I had a noisy MX3050n with dev drive issues that needed the Main Drive Assembly, and all was well after replacing it.
5 months down the road the same machine was jamming and making a weird noise. Apparently the motor that drive the Transport Assembly was worn at the spiral gear just the same.
Sharp is out if stock on this motor and gonna try CPLTM8993DS51 Transport Drive Motor Assembly that includes the motor in question.
Here's my pics :

I pulled the paper feed motor (just above the transport motor), same part number, and there is wear on the gear in the same area where it meshes with the next gear. So looks like that one will be next. If that happens, that will make 3 major drive assemblies in one machine. 38K blk and 22K clr.
FYI: for a temporary fix that actually worked until part comes in
I shimmed the motor assembly mounting screws by applying washers in between the copier frame and motor mounting bracket. This moves the "bad" part of the gear away from the mesh and good part of the gear to drive the assembly.
hope it helps for you too
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

The motor issue is 90% of the time to do with toner between the gears due to spillage during shipping. The toner on these models has dev in it as well and as such is quite abrasive. When replacing motors strip ad clean the whole drive unit or the issue will return. lubricate with the correct greases as per the service manuals. I noticed in the photos the gears are very dirty. I will bet this is toner / dev.
