Answers: The hose from the non pressurized end of the cylinder acts as an extended reservoir. To do this it needs to be connected to the reservoir. there is no provision for this use, so a 1/2" npt "T" and a close nipple, are used in the bottom of the pump housing this allows draining and access to the reservoir for the hose from the non pressure end. Putting the hose in the filler pipe will not allow it to suck and push the extra fluid. Doing this keeps the cylinder lubricated at the packing, keeps water and dirt out, and allows a larger res capacity. The control rod with a loop on the end has 4 positions (three being used) hold is a mid travel position with the little welded on tab hooked on the support casting. This is basically neutral, and holds the cylinder/s at their current position. Pulled out all the way, it lifts. Pushed in all the way it lowers. Pushed in 1/2 way from hold is delay lower. (operates on the left rear outlet only) You can ignore this aspect unless fitted with a old IH cultivator, or other sequential lift implement. Both left and right regular outlets are "T"ed together inside, not separate. IH Hytran or JD hydraulic Transmission fluid are great. I would not use the ND oil as it may have been as good as was available then but Hytran has much better properties. (it will mix with residual oil in the unit, no flush needed after draining. JimN
