641 diesel throttle issue

I am helping a friend with his 641 D. Throttle will not stay put when you throttle it up. I notice a spring under the throttle shaft and a spring washer on the (what i"m calling) the pivot under the battery tray. I do not see any other springs of anything else at the injector pump. Will a new spring washer help. If so, where can I get one. Thanks
 
On two different tractors, I've had oil get onto the friction disk and make it too slippery to hold. Needed cleaning and new disks and, obviously, needed to stop the oil -- one was from a leaking valve cover and the other was from the auxiliary hydraulic controls mounted on a loader.

Good luck.
