I talked to Kyocera support and they suggested that I try this bulletin to help with machines that are over heating the drum units and causing the toner to harden inside the drum unit resulting in broken gears, etc.
Has anyone tried installing all the parts listed in this bulletin? Does it really work? Is it a nightmare to replace these parts? Thanks.
The drive assembly is a bitch to replace. Much stuff on the rear side of machine must be removed. We usually replace the entire assy, but have rebuilt them with gears when necessary. Never had to go back in a second time for the drive unit.
If you're getting some gear noise, and the front tips of the cleaning augers have a nice toner rock each you might want to start elsewhere.
The miter gears that drive the waste bottle drive can jump teeth. It's about the inferior plastic C-clips allowing too much gear lash. To see these gears remove the toner bottle holder, and separate the metal support frame from the plastic cover.
Replace the plastic C-clips with metal E-clips and place a few 0.5mm shims behind the miter gear to snug up the gear lash. If you're lucky you may be able to clean some of the drum/cleaning units. You'll probably have to replace a few of the drum units.
As testing goes, you'll only hear the noise during printing or copying. If you run the paper conveying motor in simulation U030 you won't hear the noise. There is a clutch that is not engaged in the simulation, but engaged during coping.
Does that sound familiar?

I checked those miter gears and drive plus replaced plastic clips with metal. I did find that the paper jam access gate labeled 'B1' that is supposed to latch securely, drives the waste toner gears. There was so much play between those gears that I am starting to think that the customer opened that access gate and then failed to securely latch it, which resulted in no gear mesh and no drive of the waste toner.
