[Shop-talk] Clean and lube suggestions for A/C fan

[Donald H Locker]

My window air conditioner started up a few days ago sounding very ill. Clearly the fan/blower bearings are noisy, so I pulled all apart, cleaned and am thinking lubrication would be in order.

I think it has sleeve bearings, but I'm not certain. I just spun it again and it feels like balls without the fan and blower attached. (GE; 1/10HP; 1000/860/700 RPM; 120VAC; 1.40A; 1-phase double-ended; thermally protected; class B insulation; "SKCP 29HC A101CS" (presumably model or type) if anyone recognises it.)

I haven't used any solvents yet on the bearing region, because I don't want to wash any crud into the bearings.

I am soliciting suggestions for cleaning and re-lubricating the bearings - most things are accessible but the motor case is riveted shut, so I'll not be opening it that far.

Donald.
