Tag Archives: ball-bearing swivel plate (H3-40 seats)

2015/11/04 (W) Southbound Liberty

Linda decided last night to work at home today rather than driving into the bakery in Hamtramck.  That meant she did not have to get up at 5:45 AM.  She was up just before 7 and I was up just after that.  I made a large pot of Sweet Seattle Dreams half-caffe coffee and Linda toasted slices of cinnamon raisin bread for breakfast.  After breakfast she settled in to work at her desk while I tended to several chores.

I last changed our whole house water filter in May (of this year) and it looked like it was overdue for replacement.  I had one filter element left so I used it.  The process is simple enough:  I turned off the well pump, shut off the valves on either side of the filter housing, released the pressure in the housing, and unscrew the removable bowl.  When I unwrapped the filter and read the directions I was reminded that I am supposed to clean the bowl with warm, soapy water, rinse it clean, and then sanitize it with a bleach solution and rinse it out again.  That requires water, of course, but I had the water shut off and the filter housing disassembled so I had n way to turn the water back on.  The only way to accomplish this would be to stage the needed water before shutting off the water system but I never remember to open the new filter element are read the directions before I start.  I mean, really, it’s not the sort of procedure that requires me to read the directions each time.

Not having any running water I wiped out the bowl with paper towels as best I could.  The directions called for lubricating the main O-ring with silicon grease.  I knew I had some from the last time I changed the filter.  It was hiding in plain sight but took me a while to find.  After greasing the gasket and installing it back on the bowl, I put in the new filter element and screwed the bowl back into the filter head, tightening it with the filter wrench.  I turned the well pump back on, opened the inlet and outlet valves for the filter, and let the trapped air out with the purge valve.

Our filter housing takes a larger than usual element.  It is 10″ long, which is the most common length, but 5″ in diameter, which is much bigger than usual.  It’s a dual density spun polypropylene material with a 50 micron nominal rating at the large outside surface and a 5 micron nominal rating towards the smaller core.  These filter elements are not available at the local home stores so I get them from Adam’s Well Drilling and Water Treatment, who installed out current water treatment system.

I gathered up the laundry and put a load in the washer.  I took the label from the new filter element and headed out on an errand run.  My first stop was Adam’s where I bought four filter elements and two bottles of chlorine tablets for the taste and odor portion of our water treatment system.  Wilson Marine is located next door to Adam’s so I stopped there to see if they sold marine grade plywood.  They didn’t but I had a good chat with the associate.  He suggested that for patching the floor in the bus I just use treated plywood or use Thompson’s Water Seal to treat whatever wood I use.

My last stop was O’Reilly’s Auto Parts.  Their parking lot was finally open so I could park near the door.  Ronald had me load the containers of used oil and the bag of filters into a shopping cart.  The bag had leaked onto the paper towels I put under it in the back of my car so Ron gave me a cardboard box to put it in.  He simply put the bag of filters in a container but he emptied the six containers of oil and gave them back to me.  They recycle oil but not the containers.

When I got home Linda checked to see if we could take the plastic oil bottles to Recycle Livingston.  Used motor oil is considered hazardous waste and anything that has had used motor oil in it is considered a hazardous material so we could not take the containers there.  I helped Linda load all of the other recyclables into my car and she made a run to the recycling center, the first in a few weeks.  After moving the laundry from the washer to the dryer and putting another load in the washer I got back to work on the bus floor.

I spent most of the afternoon working on the floor under the front passenger seat.  First I removed the blocking that provides support for the bottom edge of the switch panel but also spans the three floor boards.  I cleaned out the mouse nest behind the switch panel and found the skeleton of a small mouse.  I then got the piece of wood between the mounting channels out.  The drain line for the front CruiseAir evaporator went through this floor near the outside edge but the floor was rotted enough that I was able to break out the wood on the back side and pull the board out.  As I did this I was reminded, once again, about how much of this conversion was built with the idea that it would never have to be disassembled.

I took a break for lunch, which was leftover lentils and quinoa pilaf with some fresh fruit.  After lunch I resumed working on the floor under the front passenger seat in the bus.  I managed to remove most of the rusted metal filler plate.  I made a lucky guess as to where my wire brush was stored and used it to clean the surface of the rusted metal that remained.  I played with different combinations of wood thicknesses and pondered how I will rebuild this area.  I then sprayed the rusted areas with POR-15 cleaner/degreaser and scrubbed them with a sponge soaked in hot water.

I moved to the driver’s seat area and repeated the process.  There was one area with damaged wood that I still had to deal with.  There was an edge about 10 inches long capped with two thin gage metal angles that were badly rusted.  I removed as much of the angles as I could.  I cut off a strip of wood about 2″ wide and 10″ long and removed the rest of the angles.  I wire brushed the area but left the POR-15 cleaner/degreaser for tomorrow.  In anticipation of applying the POR-15 tomorrow and coating it with black spray on rubberized undercoating paint I began masking off the area with painter’s plastic.

For dinner Linda made a salad, roasted eggplant with garlic and breadcrumbs, and mock fish with vegan tartar sauce.  We finished the Frey Natural Red wine with our meal.  I would love to support this company but this wine is too dry for my pallet.

PBS had an interesting lineup of shows this evening on continental formation, natural wonders, and the human brain.  I dealt with e-mail before the shows and we turned in after the last one.  Chuck and Barbara were planning on leaving this morning, southbound for Florida in their 1993 H3-40 Liberty motorcoach.  I did not have any messages from Chuck today so I presume they got away as planned.  They bought a lot at the Pelican Lake Luxury Motorcoach Resort in Naples where they have spent the last six winters and that is where they are headed.  We will be staying about 90 minutes north of there in January and February and will get together with them as time and commitments permit.  We are looking forward to seeing their lot; it has a coach house and they are doing some landscaping, including large palm trees.

 

2015/10/27 (T) The Pilot’s Seat

My morning started at 8 AM in its usual fashion.  I fed the cats, made coffee, started a load of laundry, made/ate breakfast (orange/grapefruit juice and granola with fresh blueberries), drank my coffee in the living room with the fireplace on and Jasper at my side, day-dreamed about high quality used Sony alpha lenses, and finally got to work on the bus a little after 10 AM.  Rain is coming tonight and forecast to stick around into Thursday so today would be a good day to do some more trimming, felling, and cutting up of dead trees.  The temperature this morning was still in the 40’s, however, and there is still much to be done in the bus.

A few days ago I installed a new AC outlet on the forward side of the cabinet behind the driver’s seat.  I wired it into the outlet on the aft side of the cabinet and then discovered that the original outlet was cracked.  I had also used an oversized cover plate on the new outlet and it interfered with the Corian cabinet top.  I finally got around to replacing the cracked outlet this morning.  I also switched the cover plates.  The regular size one still interfered slightly with the Corian top so I cut 1/8″ off of the top edge and added strips of felt on the three edges of the cabinet to raise the Corian top slightly and cushion it.  Everything fit nicely.  I turned the circuit breaker on and checked for power.  The outlets were good to go and I checked this mini-project off my (mental) project list.

I took a break and called the Escapees RV Club to register Linda and me as staff for the July 2016 Escapade.  I then called Josh at Coach Supply Direct regarding extra brackets for our MCD shades/brackets, the wiring of the passenger seat switch, and the correct orientation of the swivel bearings.  I learned that the flange, which wraps around the other piece on the inside of the ring, goes down.  (I had puzzled out that it should go the other way so I am glad I asked.)  When I was done with my phone calls I had a quick lunch of Sabra Roasted Red Pepper Hummus and Snyder sourdough pretzel nibblers.

My next task was unbolting the driver seat pedestal base from the floor.  The pedestal is secured by four large carriage bolts that go through holes at the four corners of the base plate and thread into nuts that I presume are welded into the floor structure.  The base had to be removed in order to remove the old vinyl floor tile which was installed under the base.  To get the old tile out I also had to remove a plastic cover around the steering linkage and a floor mounted bracket that retained the bottom if it.  Last, but not least, I had to unscrew the accelerator bracket from the floor by removing three small lag screws.  The accelerator is electrical, with a cable that runs through the floor, but other than limited access it was easy to detach.

Removing the old vinyl tile from the driver’s area of the cockpit was relatively straightforward.  It’s somewhat flexible and wasn’t glued down that tightly.  When Creative Mobile Interiors installed the tile they laid it out in a way that allowed the pieces to be trimmed in reasonable ways to fit around the steering column and brake pedal.  The brake pedal is mechanically linked to a complex multi-port air valve in the compartment under the floor and any finished floor has to be installed around it.

The plywood under the driver’s seat area was depressed directly under the base.  It seemed unlikely that this was the result of the base being bolted down.  It may indicate that this area also got wet like the area under the passenger side seat base.  I plan to install SurePly underlayment on the floor under the passenger seat but not the under the driver’s seat so I will either have to replace this piece or use floor leveling compound to fill the depressed area.  Replacing the plywood is probably the correct, but more involved, solution.

I started thinking about installing the new tile so I laid out all of the old tiles on the floor in the garage, kind of like putting a simple jigsaw puzzle back together.  I plan to use them as a pattern to cut the new tiles.  With a clear view of the whole driver’s area I became intrigued by the lower sidewall counsel next to the driver’s seat.  The more I looked at it the clearer it became that Royale Coach had cut the top off of a bumped out area, removed the upper three inches of the wall of the bump out, replaced the top piece, and tried to fill in the three inch gap in the side wall.  They had also cut out an access plate and then screwed it back in.  It eventually became obvious to me that they had done this to create horizontal space for the wide Villa driver’s seat that was in the coach when we bought it.  Had Royale Coach left the ISRI seat in place these modifications would not have been needed.  They were originally hidden under carpet but once the carpet was removed the really poor quality of the workmanship in this area was all too apparent.

I probably should have applied adhesive remover to the stairs and walls around the cockpit but it has to sit for 1 to 3 hours and the timing wasn’t right.  The weather was still decent and I needed to finish working on the trees at the west end of our property.  The adhesive remover can be left on for up the 24 hours so applying it at 5 PM with the intent of removing it the next morning might be ideal.  The weather forecast for overnight, through tomorrow, and into Thursday, however, is for rain and colder temperatures, so they will not be good mornings for working with the door of the bus open.

Around 3:30 PM I had a banana nut muffin and then called Phil at Precision Grading.  I got his voice mail and left him a message.  I was getting ready to use the chainsaw to cut down a small dead tree at the west end of the property when Linda texted that she was leaving the bakery.  A few minutes later Chuck called.  He had some carpet remnants for us and was nearby so he came over.  He could not stay long but took the time to look at what I was working on in the bus before he left.  It would still be awhile before Linda got home so I took the chainsaw to the west end of the yard, cut down the tree, de-limbed it, and cut it up into manageable size pieces.  I then cut up another tree of similar size that has been on the ground for a while and cut up some of the larger branches that I trimmed off the trees yesterday.

Linda got home while I was finishing the tree work and started fixing squash and a lentil/quinoa pilaf for dinner, both of which would take some time.  After cleaning the saw and putting it away I took one of the carriage boots from the bus driver’s seat and went to Lowe’s to see if I could find slightly longer replacements.  The old ones were somewhat rusted and some of the threads were in less than ideal condition.  The new Armstrong vinyl tiles are also a bit thicker than the old ones and I wanted to make sure I had bolts that were long enough to completely thread into the retained nuts.  It turned out that the bolts are metric, specifically M12-1.75×80.  Lowe’s had Grade 8 M12-1.75×90 bolts (10 mm longer than the 80s) so I bought four.  I also bought some thick M12 fender washers that were larger than the old ones.  While I was there I picked up a role of red electrical tape.

Dinner was excellent.  The squash was baked without butter (vegan) or brown sugar but was very tasty.  The pilaf had onions, garlic, and mixed greens and was very good.  We finished the Witch’s Brew wine from Leelanau Cellars that Linda used to poach the pears on Saturday.  The squash did not look that big, but neither of us was able to finish our half so we saved it for tomorrow’s lunch.

I checked e-mail after dinner and then we settled in to watch our Tuesday night TV programs.  We caught the weather report at 11 PM and then turned off the television and lights.  I turned down the brightness on my iPad display and worked for another 30 minutes before going to sleep.  I did not hear back from Phil this evening but I already knew he would not be here on Wednesday if the rain came as forecast as he had another job to work on that was better suited to working in rainy conditions than ours.

 

2015/10/25 (N) Bus Dinner

It was 44 degrees outside when we got up this morning but cozy in the house.  We were out of Linda’s homemade granola so we had oatmeal for breakfast.  It’s a nice change of pace on occasion and was a hot, hardy start on a chilly day.  I made a pot of Sweet Seattle Dreams coffee and we had a quiet morning in the living room.  We talked about going to the Howell Farmers Market, as today is the last day of the 2015 outdoor season, but did not need anything and given the temperatures decided not to go.  I changed into my work clothes at 10:30, went out to the bus, and turned up the thermostats to raise the interior temperature.

My focus in the bus today was tasks that I could not do alone.  I got my 15/16ths closed-end ratcheting wrench and removed the main retaining nut from the driver’s seat and from the front passenger seat.  Each of these nuts threads over a vertical stud that is fixed to the pedestal/riser which is in turn bolted to the floor.  In between the top of the riser and the bottom of the 6-way power base is a ball-bearing swivel plate which is centered on the mounting stud.  To get to these nuts I had to move the seats forward using the motorized bases and reach in from behind but I had good access and the nuts were not hard to loosen and remove.  I bought this closed end ratcheting wrench specifically for removing/installing these seat mounting nuts and it was worth every penny I paid for it.

With the nuts removed I unplugged the 12V DC power supply wires to each seat.  Linda and I were then able to lift the seats off of the pedestals without too much difficulty, carry them back into the kitchen (of the bus), and lay them down on their backs on the floor, which was protected with blankets.

The reason for removing the seats was two-fold:

  1. We were going to hang wallpaper on the living room walls where they merged into the cockpit and needed better access to those areas, and
  2. I plan to tile the floor and walls in the cockpit and entry this coming week and needed these seats out of the way in order to be able to do that.

Our next task, preparatory to hanging wallpaper, was to remove the walnut cover (half box) from the front eight feet of the passenger side OTR HVAC duct and wiring chase.  We set it across the two seats we had just removed to get it out of the way.

When we were finally ready to start wallpapering we needed three relatively short pieces; two to finish the driver side and one to finish the passenger side, at least as far as we intended to go.  I made a sketch for the shape of each piece, took measurements, and added them to the sketches.  The wallpaper is 26.5″ wide on the roll and the longest piece we needed was only 24″.  I got the 3′ and 6′ rulers from the shop while Linda got the roll of wallpaper.  We used the dining room table in the house to measure, mark, and cut each piece.  Although relatively small these pieces took some additional, careful, attention because they had to fit over, under, and around cabinets and window trim.  To make the installation easier I trimmed away as much of the waste material as possible before hanging the piece.

Linda partially filled two 5-gallon buckets with water, added soap to one of them, and brought them out to the bus while I retrieved the paint tray and liner and the 6″ pasting brush.  We laid out all of the wallpaper tools, put a towel on the floor, and set the paint tray/liner on the towel.  I poured the amount of wallpaper paste I thought we would need into the tray and started with the piece of wallpaper at the right end of the built-in sofa (towards the front of the bus).

As we had done previously everywhere else in the bus I applied the paste to the wall rather than to the back of the wallpaper.  The wall behind the sofa had been primed but the small strip above/behind the end cabinet and around into the cockpit had not been, so I used more paste in the unprinted areas.  This first piece required a lot of trimming so it took a while to hang but it looked good when we were done.  As I got each piece installed, with Linda’s help, she rolled the seams and then washed off the excess paste with a large sponge using the soapy water followed by a second sponge with clean water.

We continued along that wall towards the front of the bus with the second piece.  It did not require as much trimming as the first piece and went in a little faster and easier.  I overlapped the thin strip above/behind the cabinet with the first piece and cut through both of them to create a clean, tight seam.  When we hung wallpaper in our house many years ago all of the seams were done by overlapping adjacent panels and cutting through both pieces.  The paper we are using in the bus, which is actually vinyl, is installed by butting the factory edges together.  This certainly simplifies installation, and speeds it up a bit, but it is harder to get a perfect seam.  Still, it was the right choice for our motorcoach as it is washable and scrubbable and goes very well with the interior.

On the passenger side of the coach I pasted up the last section of the living room wall and part of the small section of wall under the trim on the window next to the front passenger seat.  I ended up cutting off a small part of this piece and installing in separately as the trimming required was intricate and awkward to do.

After installing the two parts of this third piece we decided to go ahead and paper a small triangular section of wall above the bottom window trim.  I got a scrap of wallpaper from the house that was big enough to cover the right triangle shape and cut it approximately to size.  I pasted the wall, set the bottom edge flush to the sill, pressed the back edge into its vertical corner, and trimmed off the excess.  This little section of wall was capped by a piece of walnut that ran at an angle along the bottom edge of the glass.  I trimmed off the paper at the bottom edge of the wood trimmed and tucked the paper in under the walnut.

The reason we did not wallpaper all of the small wall section below the window is that part of the plywood wall is severely water damaged and a piece of it rotted and is missing.  There is no practical way to replace the plywood and the only practical way to repair this area is to panel over it.  We could use thin plywood and wallpaper it but we have enough of the 1/4″ walnut veneered plywood that we salvaged from the old refrigerator to panel this area.

We were done with the wallpapering by 2:30 PM.  Linda cleaned off most of the tools and then took the two buckets of water out of the bus to pour them out and clean them.  I took the paint tray/liner, pasting brush, and some of the tools to the laundry room and cleaned them.  There was very little paste left in the tray liner so I had estimated quite closely on the amount I needed for today’s work.

The swivel mechanisms for the two front seats consist of two rings separated by ball bearings and interlocked around the inside edge.  They have an ‘A’ side and a ‘B’ side and one of them was installed ‘A’ side up and the other ‘B’ side up.  They also have a large washer.  The driver seat was installed with the washer between the swivel bearing and the power base.  The passenger seat had the washer directly beneath the retaining nut inside the power base.  Given these differences I could not tell the correct orientation and order of assembly by casual inspection of the pieces involved.  It is possible that the swivel plates are, in fact, symmetrical and thus can go in either way, but one of the washers had to be in the wrong place.

My interest in all of this was motivated, in part, by the fact that both of these seats have always wobbled since we bought the coach.  The new seats are firmly attached to the power bases which seem tight but may have some play.  I was suspicious of the swivels, however, as the main source of the play.  I studied the design for a while and came to some tentative conclusions.

When the swivel plates are installed the ring on the bottom (that sits on the pedestal) is not going to move as the pedestal is bolted to the floor.  The top ring, which will be in contact with the power base, is going to move relative to the fixed bottom ring when the seat is tuned.  I decided that the larger ring, which wraps around the inside edge of the smaller ring, should go on the bottom.  With regards to the washer it seemed to me that it should go directly under the retaining nut, allowing the power base to swivel relative to the nut without loosening it.  Further, placing it between the swivel plates and the power base would potentially prevent the base from fully resting on the swivel plate and allow the whole seat to wobble.

I will examine all of this again more carefully when we are ready to reinstall the seats.  For now, I took the two swivel bearings to the garage to clean and lubricate them.  After wiping them off I sprayed them with WD-40, worked them around, and wiped them off again.  I then sprayed them with garage door lubricant, worked then around again, and wiped them off.  Finally, I worked Red Tack ‘grease’ into the ball bearing race, spun the rings to distribute it evenly, and the wiped the outer surfaces clean.  After cleaning the grease off of my hands I took the swivel plates back to the bus, wiped the pedestal plates clean, and set them back in place.

We quit working around 3 PM so Linda could cut my hair and beard.  I then shaved, showered, and got dressed for dinner.  Linda showered after me but was dressed and ready to go before I was.  We made plans yesterday to meet Bruce (W8RA) and Linda (K4YL) at Carrabba’s in Novi at 5 PM for dinner.  We left at 4:30 and arrived in Carrabba’s parking lot just after 5.

The parking lot was not full so we knew there would not be a wait for a table.  Bruce and Linda were already there and had opted for a booth.  The booths will seat six adults so they have more table space than a table for four. They also offer a bit more privacy for conversation in an otherwise not very private setting.

Carrabba’s had changed its menu since we were last here.  The one dish they had before, Tag Pic Pak (seriously), was no longer on the menu.  It was Linda’s favorite dish and one of only two that we could eat.  They had something with a different name that the waitress said was the same but it included chicken.  She said they could leave the chicken out but the price would still be $14.95.  The Tag Pik Pak was $10.95 as I recall.  We have come to resent paying for animal products that we don’t eat.  Linda ended up getting whole grain spaghetti with Pomodoro sauce and I got whole grain spaghetti with olive oil and garlic.  Linda said the sauce lacked flavor.  My dish was “off menu” and was unimpressive.  Our salads, dressed with vinegar and oil, were OK and the bread was very tasty.  Linda had a glass of wine and I had blackberry sangria.  Sangria is Spanish, not Italian, but it was good.  The meal overall was disappointing but we had a great time chatting with Bruce and Linda over dinner.  The manager stopped by to ask how our meal was (as a courtesy) and ended up having to talk to us for 20 minutes.

Back home Linda made vegan banana nut muffins.  The organic bananas we bought at Meijer’s two days ago must have been bruised because they were going bad very quickly.  Banana bread or muffins was a great way to salvage what we could.  While she made the muffins I went to my office, checked e-mail, and off-loaded the photos we took today.

At 8 PM I turned on the Yaesu FTM-400 ham radio and participated in the SLAARC Info Net.  When the net was over I came back upstairs, reviewed the items in my B&H Photo shopping cart, and placed the order.  I then spent a little time researching DC distribution panels on the DX Engineering website and doing a Google search for cantilevered table supports and legs.  We each had a muffin for dessert and went to bed at 10 PM.  I put on the Detroit PBS Create channel, turned down the volume, and worked on this post for a while before finally going to sleep.
