Taking it apart isn’t too bad, maybe this procedure may help?  http://stickelman.net/index.php/2024/12/07/model-28-teletype-chasing-down-squealing-noises/

I used a silicone grease and it seems to be doing well, but someone with more experience may have a better recommendation.

There are oil channels but you may consider taking the motor apart to get to bearings if the oil grease has solidified.  The grease in mine was like old cosmoline or wax

Hi all, 

I've got a M28 that developed a noisy bearing. Seems to be coming from the fan side of the motor. Before I take it apart, is there a spot I should try to oil first? There's oil/grease fittings but the manuals says the bearings are "service free". Just looking for any insight before I tear it apart.

Thanks,
Frankie Caswell
