Note: The shims replace the crush ring in the cover plate. If the camplate, cover
plate or housing is replaced during servicing of the pump, the old crush ring can
not be used to make sure of proper preload.
1. Remove the crush ring from the cover plate. Measure thickness of crush ring.
2. Stack shims to the thickness of the crush ring.
3. Insert shims into the cover plate in the same location that the crush ring
was removed from.
4. Assemble housing sub assembly consisting of the housing, camplate,
bearing cone, bearing cup and cover plate (see
Repair Information, Model 70160 Variable Displacement Piston Pump).
5. Install the washers and cap screws to the cover plate and housing. Torque
cap screws to 39 N·m (29 ft−lbs).
6. Check torque required to rotate control shaft. Torque should be from 1.7 to
2.8 N·m (15 to 25 in−lbs).
A. If torque is too low, add additional shims and repeat steps 3 through 6
until the specified torque is achieved.
B. If torque is too high, remove shims and repeat steps 3 through 6 until
the specified torque is achieved.
7. Complete assembly of the pump (see
