C658 c-3102 error, fuser drive assembly?

[tsbservice]

Pretty much all of our 8 series needed to have their fuser drives replaced at 1 million, we kept a couple rebuilt fuser drives in stock and swapped out as needed.

Thanks for heads up. What parts you replacing in fuser drive and what are symptoms for you to start replacing procedure?

Main Symptom is the fuser stop turning😄. It will make noise. The rear shaft eats thru the bushing then the assy frame! The assy frame gets marred but survives. There where the drive engages and disengages by the slit where the transfer door interlocks in you will find greasy bushing dust that some times stops the fuser from engaging after opening the door.

One shaft and 2 bushings. Available to order. I just keep all the drives before machines gets eco dumped.

If the tech seats the fuser back gently and evenly it will help a bunch seat the fuser properly before fixing it down.
Get rid of the fuser AUX cleaning section at 400K. Does well without it. 1.2M yield is a pipe dream. Like mentioned 1M is the upper limit. More like 700K in my experience. Rebuild once get anther 300K from it.

It's been a hot minute but if I remember correctly,,, First indicator is noise. As allan mentioned, the shaft will wear through the bushing on the drive side and sometimes even start wearing into the plate of the drive assemble A79K255600. If the clutches are really dirty we usually replace them at the same time, might as well since you've taken it apart this far.

its possible to replace the shaft and bushings without removing the drive unit.

when rebuilding the old drive unit replace the bushings with roller bearings, they are a bit more noisy but last longer.

Thank you very much for that. One minor correction - part number for item 12 is A161702200 Bushing.

Oh, yeah, lol sorry, was going back and forth comparing my notes, manuals etc and labeled it incorrectly. I read your quote and was like "yeah, I know that's the part for it, what did I do?" lol old eyes.

Nope. Its possible to do the clutch with the assy installed on the machine but not the shaft. That is caged in there with C-clips and pins. Accounting for what needs to be done it takes a good 2 hours to complete that service. 55min if the force is with you.
