Mounting, Pump & Tank Assemblies
NOTE - The following give general instructions. Refer to
instructions included with the mounting assembly for
information specific to a particular prime mover make
and model.
Front Pump Units
1. Remove any parts, such as a knockout, that block access
to the tractor engine’s crankshaft pulley.
2. Attach the mounting assembly to the tractor.
3. Secure the drive hub to the pulley. Some tractors require a
crankshaft adapter.
4. Install the pump mounting bracket on the front of the
tractor. Position the pump so the inlet faces the right-hand
side of the unit. Do not secure with hardware.
5. Assemble the coupling halves and fasten the chain
around them.
6. Apply grease to the pump and drive shafts.
7. Slide the coupling assembly onto the pump shaft.
8. Place the keyed end of the drive shaft in the chain coupler.
9. Slide the drive shaft into the drive hub.
10. Fasten the pump to the bracket.
11. Center the chain coupler and tighten set screws.
12. Install the tank and valve assembly.
13. Install hydraulic fittings and hoses.
a. Attach the barb fitting to the pump inlet and the
adapter fitting to the pump outlet.
b. Connect the suction hose to the tank outlet and to the
barb fitting on the pump inlet. Secure with clamps.
c. Attach the 36 inch hose to the valve and the pump’s
outlet port. Tighten the fittings.
14. Go to Swing Assembly.
Rear Pump Units
1. Install the mounting assembly on the tractor.
2. Attach the pump to the rear PTO shaft and secure it
with the chain provided. This prevents the pump from
spinning on the shaft.
CAUTION - Avoid damage to the pump and other
hydraulic components. Do not use rear pump
drive on PTOs faster than 540 RPM.
3. Install the tank and valve assembly.
4. Install hydraulic fittings and hoses.
a. Attach the barb fitting to the pump inlet and the
adapter fitting to the pump outlet.
b. Connect the suction hose to the tank outlet and
to the barb fitting on the pump inlet. Secure
with clamps.
c. Attach the pressure hose to the valve and the
pump’s outlet port. Tighten fittings.
5. Go to Swing Assembly.
