Hello all. I recently aquired this 2086, it's in fair shape but has one major problem, the hydro speeds up and slows down. If you read about trunnion springs / repair this describes my problem exactly. The problem is my trunnion is in near perfect shape and the springs seem like they are about the same stiffness as the ones I bought. Is there any other problem that could cause these same symptoms? I'm about ready to send this thing to its new owner if you know what I mean.

Do you have any pics of the trunion area and have you checked all the linkage from the speed selector to the cam plate on the hydro unit itself. My 1572 was pretty sloppy because all the rod ends were shot.

Ill snap some pictures tonight. that could be the case because the lever had to be up in the "2.5-3" position for the tractor to start moving.

Here is a video with the new springs installed. The problem I think is how worn the pin is that slides in the groove of the plate

It all looks to be in pretty good shape trunnion wise. I have taken the plates apart in the past and built up the pin that rides in it with good results. I also replaced all of my rod ends in the forward/reverse linkage with heim joints. I actually found washers the correct size and installed them in between the springs and ends on the trunnion. That will tighten them up as well. Sounds like your neutral adjust needs to be centered as well. Down load a service manual that describes how to do that.

Do you think the pin could be my issue?
