Hello everybody-I have had several issues over the years with my three point hitch on my 1970 135 diesel with no pressure control in the hydraulic system.
I have opted to rebuild it completely this winter and upon attempting final by the book adjustments I have run into an issue with setting up the internal linkages.
Two manuals state that you are to prop the rock shaft up on a special block (I have used a 3/8" bolt per advice out there)
place the draft control in between two points on the guide decal and set the lift control to the very top (constant pumping)
Then while pulling back on the vertical control lever with 3 lbs of force turn the adjusting bolt until you can pass a .002" feeler gauge through the gap between the damper and the vertical control shaft.
This is not possible on my unit. No matter what I do the pressure from the return springs on the guide pins requires 10 plus lbs to pull back the vertical actuator in any but the most extremely over adjusted positions.
It all works perfectly, however, if i put a cotter key through the hole in the guide pin so that the spring is partially collapsed. In manual no picture or drawing is this done, nor online.
Everything looks right, what can I be missing?
