I have a Ricoh MPC 4500 that is making a terrible gear grinding noise that is coming from the back of the machine. The sound is localized in the bottom right corner of the machine near the Y drum/development motor and the toner transport motor. I already replaced the Y drum/develpment motor as well as the Y development clutch and the toner transport motor. If i were to take a guess i believe that it is coming from a gear that is connected to the pulley to the right of the Y development clutch. Any advice?

Go into OUTPUT and check each motor to find the cause. -

He means go to SP5804 in service mode and go through the outputs until you find the motor that's causing (or driving the gear that's causing) the noise.Comment

Re: Ricoh MPC 4500 - Bad Gear Grinding Sound
It may be the Y dev unit has siezed and stripped the two white gears that drive it. If you take the PCU out and look at the drive unit you can see them.It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
Hit it.Comment

Re: Ricoh MPC 4500 - Bad Gear Grinding Sound
Main drive gear for the yellow PCU is stripped. Remove all PCU's;look inside the machine where the Y-PCU meshes to the main drive and you may see a damaged main drive gear. I've seen this a couple of times for K-PCU's on the high volume machines.
Otherwise check that your new Y-PCU has not flipped the drum cleaning blade over causing the PCU to bind and lockup.

Hi there!
Had the same issue 1 year ago
, the end of the song was to change the complete gear-assembly (lot of fun).

Re: Ricoh MPC 4500 - Bad Gear Grinding Sound
Thank you all...it was a combination of both. The Y PCU cleaning blade had flipped up and was causing the drum to lock. I ran the output and the Toner transport motor is causing all that noise. I already replaced the Toner transport motor, so I guess the next step is replacing all those gears.Comment

Re: Ricoh MPC 4500 - Bad Gear Grinding Sound
For anyone reading this thread in the future...all the above information is very helpful, but before you go through all the work and trouble of taking apart the whole back, all the way down to the gear assembly (which I did), make sure you check you waste toner bottle, and make sure the end cap is on the right way.
Thank you all for your help
