Compensator Motor lubrication

Hi Gang,
I'm in the process of rebuilding and cleaning up the T-L system in my '55. This includes cleaning up and regreasing the compensator & motor. I took the motor off and apart and was wondering about whether to use oil or grease for the oiling wick at the base of the motor. With a wick, I would normally assume an oil, but it looks like there was grease in there so asking here. The lube charts in the manual don't address this point. I'm using the StaLube SL 3303 for the Compensator gearbox and can use that for the motor shaft wick, too. But worried it may be a tad too thick to migrate down the wick to the armature shaft in the bushing.

thanks,
Bob

You are correct -- that end is not covered in the manual but since the motor is actually a slightly modified generator case and armature I believe the same generator lube specs would apply.

thank you for the reply. Since the plate that covers the oil wick would be vertical when installed, making oil messy with no real reservoir in that orientation, I thought grease would make sense.

But since these motors don't spin as often as a generator, I was thinking they wouldn't get warm enough to melt grease so oil would make sense.

The generator lube chart in the SM calls for drops of 20W oil (every 1,000 miles! Who does that?) but it has oil cups to drop the oil down...

The wick on this T-L motor touches the armature shaft (vs oiling an oil-lite bushing) so I was thinking grease..

:)

Maybe it really doesnt matter as long as there is oil or light grease there vs nothing at all.

The stuff I pulled out felt like grease vs congealed oil but never can be sure..

Updating in case others are rebuilding their compensator motor. Following Howard's input that this motor was a reconfigured generator, that helped me be more precise in my Googling. I found this link which really helped me. The backplate isn't exactly like our motors, but the rest looks the same. I didn't replace the bushing so didnt have to do any drilling, etc. I bought a new wick (John Deere Wick R11201, $1.61) from this site https://www.shopgreendealer.com/John-Deere-Wick-R11201.html and it was the perfect thickness.

Hope this helps someone else, someday
