SMTA HYD Pump

farmhand · Sep 3, 2014

Looking for the parts numbers to the seal and oil rings for rebuilding the Hyd pump on an SMTA. Local dealer not much help in finding what I need. Motion Industries has seals but are for grease only not for oil pressure. I would like to see a parts break down of the pump if someone has it. Thanks for any help out there.

Look at hydraulics for a 400 or 450 on the case ih parts lookup site for a exploded view. Most stuff for the pumps is discontinued from case.
Need to know the type pump also. looking at the pump housings from the rear looking forward. Thompson pump will look oval shaped above the hydraulic lines manifold. Pesco will also but they have a C shaped dip on each side at or near the two top mounting bolts area. Pesco was probably original on the SMTA.

It is my understanding that these pumps are NOT rebuildable. You can't get parts because there are no parts. They are throw-away pumps. The only solution is to buy a new one to the tune of $900 and change.
