E2550c Loud Squeak

[tech07]

This 2550c has a very loud squeak that seems to be originating from the left rear of the copier. It has characteristics of a squeaking clutch but after removing rear cover and listening to machine make copies, I dont think its a clutch. It only squeaks when the lower motor (feed/developer ) is turning. The noise seems like its deeper inside. Normally, I would just tear into it and look for an issue but this copier is in a construction trailer with an inch of red clay dust everywhere. I'll need an extra change of clothes everything is so dirty. So, any suggestions on this that might save some agony ? Squeak, Squeak, Squeak

I've encountered the loud squeak from 2nd transfer unit, problem resolved after lubricated the 2nd transfer roller.

Remove the black grease on the paper exit assembly bushings and replace with with some super lube.

Take a glance at the black developing unit bearings. I've seen quite a few of these seize up and squeal. =^..^=
