It's a linkage that hooks to the rockshaft upper arms, most of the time on the right arm. It stops the 3pt from bottoming out all the way up. I do not have a picture for you, sorry.
Well I took the hydraulic pump off. Now trying to get a rebuild kit for it or see how much a new unit is. The problem I have is there is a 6 spline sleeve that goes over the spline shaft that is worn bad. So either I have to get the spline shaft machined for a key way or buy new pump gears which along with a rebuild kit are about impossible to find. Anyone know of a good place to look for a rebuild kit for a KYB pump? Number is GPH1-35CY if anyone has one laying around
