Bobcat 642 Problem

[Schifference]

Hello, I have a Bobcat 642 and the right hydro motor is noisy and almost non responsive. I switched hoses coming off the pump on both sides front to back. The right drive motor works fine now with the left control handle. I read in an old forum that when this is the case the pump needs to be disassembled and "swash" plates can be sanded. Old Forum thread: http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=54&frmView=ShowPost&PostID=11488 Are they called swash plates or splash plates? Any input on how to do this will be greatly appreciated. Winter is knocking on my door and I have not finished my summer project. Thanks in advance!

So I removed the pump assembly and I am hoping someone will chime in on what I need to so to hone/sand/fix the swash plates. I don't want to take apart anymore of it than necessary. Thanks! I don't know if I have the ability to post pictures. I do not see any way to do that.
