The motor in my '61 A700 does not look like it can be oiled. It works great and looks like new. It looks original to the machine too. Should I leave it alone or should it be disassebled and have the bearings/bushings oiled with turbine oil? I know some motors use an oil impregnated-type bronze bushing (called "oilite") but I don't know if these are like that. The motor has "Maytag" ink stamped on the side but was made by GE.

Thanks for any advice - and for putting up with all of my questions!

Andrew S.

Do you have the round style motor? If so, yes. I disassemble, clean, file down the start switch contacts, lube the centrifugal clutch, and oil the spongy pads for the motors bushings with turbine oil. Always makes for a happy quiet motor.

Thanks Dan

Yes, it is a round case motor. I was hoping to "get away" with leaving it alone but I guess I had better service it now to ensure a longer life. I bought some turbine oil that I used on the pump so it can go to good use here too.

I always say "if it ain't broke, don't fix it". A little PM can't hurt, as long as you can get it back together OK.

That was my original thought too, but it may be dry of oil b

When I take it off to change the carriage rollers I'll survey how difficult it looks to take apart. If it looks like a problem I may leave it alone. At least new motors are easy to get for this model.

The transmission is another item that I could get into, but since it isn't leaking and is nice and quiet I'll let that sleeping dog lay.

Oh, before you take the motor apart, turn the motor shaft back and forth a few times to get a good feel how it reacts. This will help guide you to align the motor by slightly loosening/tightening the motor case rods and nuts once it's time for re-assembly. If the alignment is off, the motor shaft will be hard to turn or will be frozen in place. I also use a black marker on the casing and top/bottom halves so I can put the motor back together exactly like it left the factory.

OILING WASHER & DRYER MOTORS

Great advice Dan I do think its worth trying add oil to older motors that are being put back into regular use. On the newer aluminum frame glued together Emerson motors [ in use since 1971 ] I will even drill holes in both ends into the felt wick area and add oil. I have saved many motors this way.

Ahhhh, so that's the trick to sneak a little oil in the sealed motors. Is there a specific area to drill or just anywhere at the end caps? Thanks for that bit of advice.

I found it makes a huge difference in

motor life. I broke down two of my Duomatic motors and you can hear the difference in the 3rd one I rushed into service.

Good reminder, must get that motor out and service it!
