Motor is refitted, up and running nice and smooth.
Great result.

The motor has failed after 147 miles. At first I thought it was the bearings until I opened up the motor and found this.

Have emailed Xiongda about some replacment gears.
AWOL. this happened to me. You need to replace the white, dry lube with some good PFET gear grease on one side, and some PFET drip lube on the other. I did this after getting my new gears and have quite a few miles. Been almost 3 years. Look in the endless sphere forum and read what d8veh wrote. Need to skip around - he wrote a LOT.

Thanks for the info, I have often wondered what that white grease is inside a motor.

Any idea where pfet gear grease can be sourced?

Probably a typo and should be white PTFE grease, which is easily available.

Not a typo. Worse, bad recollection. After 3 years of no problems I forgot the abbrev. Thanks, you're right Neath, and my brand was Tri-Flow. My light drip lube is also PTFE Tri-Flow. I amazoned, I believe...

BTW, pretty sure that skummy stuff your motor came with is NOT PTFE white gear grease. It's sticky, with no resemblance to me of the slick, translucent "white" PTFE gear grease.
