[GreenKeys] M28ASR Motor Saga

[Steve Garrison]

It is definitely the bearings!  With the motor assembly removed from the
base, spinning the motor quickly even by hand is quite noisy.  Under power
on the test bench it is a very noticeable noise and qualifies as the "funny
sound" I was hearing after replacing the fuse blown by my mistake and
powering the machine back up.

 

Live and learn, and at my ripe old age I still learn something new every
day.

 

I now need to replace the bearings.  Does anyone have a Teletype part number
84020 bearing puller the wouldn't mind parting with?  Or maybe I should
check with Paul Cembura.  Or just use eBay or Amazon.

 

I already have the bearings on order.
