Working on a CC 882 with Hydro. Received the rebuilt valves back today and installed them. Went out to mow and have a run away problem. On a slight down hill grade the tractor will speed up a bit and then roll to all most a stop.
Then the hydro catches up, it jerks and off we go again, only to do the same thing. Pulling up that same slight grade it works fine. I checked the linkage and control parts and found that the pin on the damper spring plate assembly is wore flat on the two side that run in the slot of the came. Could this be causing the problem or could the spring be week in the trunion be week? The trunion looks good and measures out good.
The control lever has to be about 1/3 of the way up before the tractor will move and then it is with a little jerk. I am thinking those flats places on that pin are causing this problem.
Any advise would be appreciated.
