Super M Hydraulic Reservior

David Goode · May 24, 2008

Is The Hydraulic Reservior of a Stage I Super M just held on by six bolts? I see six bolts that seem to hold the "oil pan" of the reservior on. Then how hard would it be to remove the old pump? Is it direct drive from the engine? Thanks for any help.

David - The Stage 1 SM hydraulic reservoir his held to the underside of the belly by 4 capscrews. It's driven by a slotted flex coupling from an extension of the transmission countershaft - ie. from the REAR of the reservoir.

Removal the pump/reservoir is not difficult. But it is HEAVY and kinda awkward to handle (it's top heavy)

First remove the dust cover in front of the reservoir, disconnect (unscrew) the 3 hydraulic outlets and remove the control lever. Then put a transmission jack beneath the resevoir to hold it up, remove the 4 cap screws holding the reservoir in place, and carefully let the jack down to lower the reservoir. Be careful - it will want to tip over and fall off the jack as soon as it is free of the tractor belly!

Alternatively the reservoir can be lowered by removing 2 diagonally opposite capscrews and replacing them with 2 lengths of 3/8" threaded rods and nuts. Run the nuts snug to the underside of the reservoir mounting flange, remove the remaining 2 capscrews, then alternately turn the nuts down on the threaded rods to lower the reservoir.

Bob, I think he will also need to take off the coupling cover behind the pump. allowing access to the drive coupling. I also wonder if putting an old piece of Hydraulic hose on the filler stand pipe would allow some directional control? A woden (jorgensen) type clamp could be loosened or tightened to keep some tension on the top of the pump! JimN
