Mobile Maid Akron OH rebuild

John----one last question

I always have another question for John--I think I owe you a Hanukkah gift!

 

What's left of my schematic shows 3 windings inside the motor, Pump-Wash-Run. And the bottom of the diagram, the "ladder" section, shows the colors of wire for each. While I'd prefer to heat the Calrod for Wash instead of whenever the motor is running, if I use the WASH wire it's just the start windings and will turn off the heat once the motor is up and running? I believe I need to use the RUN wire to power my new relay, Yellow/Red joined to YEllow, and the heater will always work when the motor is running in any direction.

 

The top half of the diagram shows the YellowRed coming from the motor relay to the motor Yellow.

 

The relay is in the mail, hoping to get this done right with one more opening of the innards.

 

Thanks again-----this MobileMaid washes EVERYTHING. Sorry the pic is on its side.

120 Coil Relay Addition

Yes Mark I think it will be easier to just wire the heater to run whenever the motor is on.

All good

John-----it's wired up perfectly with your advice, and I even temporarily hooked up a test light to prove exactly when the heater goes off and on, exactly with the motor. And exactly with the little click from the new relay.

 

While I had the machine on its side, I undid the 4 motor screws, the wires left just enough slack, and wiped clean the sleeve bearing and spindle, then some 3-in-1 non-detergent oil on it, all back together now and one great load of dirty dishes done.

 

Also, while crawling around and scraping more paint off the cabinet, a better read of the nameplate says AMPS 6, more evidence that this rare model SP390B3 did not ever heat the water. UNTIL NOW!  And the motor says 2-18-66, not as old as me but still running.

 

Thanks for your help, John!

 

All done now except for painting

Mark, the Mobile Maid looks perfectly at home and welcome in your kitchen. That's the same kitchen I LIVED IN at my Aunt Margaret's house with her Easy Spin wheeled up to an identical sink. Your sink is now coveted by newbees, paying fortunes for retro redesigns of their kitchens. Cool idea with the table cloths. I have one exactly like one of yours. But most of all, I admire and envy your mechanical skill. Good on you, Dude! Top Load Portables Rule! Can't wait for the day when you tackle a Combo.

Thanks-----I had a kitchen table in there for ages, and collected about 10 50's print tablecloths, and used them and loved them. When I remodeled and put a 50's Westinghouse roaster and a cabinet for a Nutone Food center in, I had to get rid of the table.  All those great tablecloths had to go somewhere! The sink installation made me lose the doors under it, so more tableloths now act as curtains there. Most of the tablecloth/curtains do NOT match, but look great anyhows, I love it and appreciate your comments. Tough luck to old Martha Stewart.

Motor

Motor problem---this machine has done a load of dishes wonderfully about every other day for 10 days------then tonight it ran through most of the cycle, got to final rinse and worked fine, paused then advanced for the final pumpout, I heard the relay click and then nothing.  I advanced the timer and slowly advanced it through another cycle, each time the motor should run it clicked once, buzzed a bit, never started up. I waited for cool-down time, an hour, to see if thermal overload had kicked in, still nothing. Finally I emptied it and turned it on its side, probably 2 hours after the screwup. With no disassembly at all, you can stick your fingers into the motor bottom from underneath.  At first the blades were entirely stuck, soon my fingers freed it and it turned nicely. I set it up straight and turned it on, it ran perfectly through another load of dishes.

 

About 2 weeks ago, doing other repairs, I had the bottom of the motor off and added 3 drops of turbine oil to the bottom bearing, but I've never seen or touched the top bearing.

this pic is stolen from another thread, but is my same exact motor. Sleeve bearing at the bottom

more stealing

this pic should be the top view of my motor, but I've never had it that far apart. So yes I need to start some Ebay searches on GE motor WD26x56 or WD26X63. In the meantime, take it apart and get some cleanup done and then some turbine oil? I imagine the bearings are pretty much factory assembled to the motor, it's nothing I should think of replacing myself? Turbine oil for a sleeve bearing is correct?

 

Everything else is working wonderfully, this machine cleans everything, but a reliable motor is necessary.

 

Thanks in advance for any advice. So far I know it's a reversing motor with a sleeve bearing at the base, no capacitor but it has a relay mounted elsewhere,  not much else. But I am less fearful each project of getting into motors, relays, timers, etc. That's thanks to all you guys--

Thanks

Mark

 

PS. If I properly attribute 3 photos to Rollermatic, with thanks, I shouldn't end up as someone's prison bi&ch.

GE DW Motor Problems

Hi Mark, sorry your motor is having problems. These motors do use just sleeve bearings on both ends and turbine oil is great for this purpose.

 

I was never a big fan of this motor and pump system on GE DWs, and I always found that 3450 RPM DW motors that just had sleeve bearings to be not all that durable. D&M, WH and HP DWs also only had sleeve bearing main motors in the 1960s.

 

Overall the 1960s was not a time of real durable DWs [ with the exception of Kitchenaid ] even the great performing WPs were of poor long term durability [ pump and motor problems ] and WH , D&M and HP were throw away machines after a few repairs, LOL. A typical family running the DW once or more per day often got less that five years use out of a DW before replacement.

 

The best advice I have for DW collectors on this site is to try to find those rare machines that had little or no use if you expect to use them as everyday machines. Mark you may end up needing another motor and pump for your machine, if you do I may have a good used one, contact me if interested, John L.

John

I always appreciate your advice. I'm gonna take the motor entirely apart and get turbine oil in both bearings, then I will use it less. This is a high-mileage machine for sure, and it's a case of "you get what you pay for" which was only $20. IT washes fantastically, but I don't want to wear it out in another month.

Deep restoration!!

I love such deep restoration, and the timer rebuilding is my favourit activity especaially in cool winter spending hours and hours near th fireplace!!!!

Have a nice wash re-start!!!
