Bearing

Hi, can anyone tell me what the bearing behind the panel is called? The bike is a KZ750 N1 spectre 1982 and the bearing is rumbling slightly. Thanks

Partzilla has a photo of the bearing & from the info on it, the outer Fr bevel gear bearing is a NTN brand 4T 30205.
There's also a shim etc, so you should read the manual to see what needs to be done. I don't know anything about a shaft drive.
If you need a service manual, search EB for KZ750 shaft manual. There's usually a number of them listed, often times cheap.
