If you remove the inspection plate on the RHside of the transmission casing you can see the control valve actuating lever and the roller. If you then have the engine running it is possible to move this lever (using a metal bar) and actuate the pump. DO NOT PUT YOUR HANDS INSIDE WHILST THE ENGINE IS RUNNING, BE VERY, VERY CAREFUL. If this raises the lift arms then you have done something wrong with the linkage system.

While lubricating the works in the top cover with WD-40, I noticed a round cam follower was pushed off the flat steel in which the round follower followed a curve. I gently pushed the round follower back so the described steel curve would be over the round follower. Working the controls I saw very little movement of the two flat steel fingers that operate the pump. After the top cover was reinstalled – in the same fashion as during it’s previous re-installation, the hydraulics did not work at all – not even the slightest of pressure on the piece the big piston in the top cover is attached to.

I had carefully removed silicon used to form a gasket for the top cover and wonder if a small piece of that may have clogged the pump, or, did I foul something up in the control linkage causing such little movement of the two fingers and that causing the pump not to actuate to move fluid? Any idea what I mucked up? Thanks for the reply – I need to get this working before the snow flies in Southern Illinois, US.
