pump housing. Make sure the cast knob on the swashplate fits over the bias spring and that it settles
properly unto the journal bearings.
Input shaft
Insert the input shaft (J010) through the bearing into the housing.
Cylinder kit assembly
1. Coat all parts with hydraulic fluid prior to reassembly.
2. Install the inner block spring washer (K042), block spring (K043), and outer washer (K044) into the
cylinder block. Using a press, compress the block spring enough to expose the retaining ring groove.
Wind the spiral retaining ring (K045) into the groove in the cylinder block.

Warning
Risk of personal injury: Compressing the block spring requires about 350 to 400 N [80 to 90 lbf]. Use a
press sufficient to maintain this force with reasonable effort. Ensure the spring is secure before
attempting to install the spiral retaining ring. Release the pressure slowly after the retaining ring is
installed.
3. Turn the block over and install the retaining ring (L Frame only; K048), hold-down pins (K046), and
ball guide (K047) to the cylinder block.
4. Install the pistons (K050) to the slipper retainer (K049). Install the piston/retainer assembly into the
cylinder block. Ensure the concave surface of the retainer seats on the ball guide. If you’re reusing the
pistons, install them to the original block bores. Lubricate the pistons, slippers, retainer, and ball
guide before assembly. Set the cylinder kit aside on a clean surface until needed.
Be sure to install the slipper retainer so it mates correctly with the ball guide (concave side of the slipper
retainer against the convex side of the ball guide).
