Cylinder kit installation
Set the pump on its side. Secure the end of the shaft with one hand and keep it horizontal. Insert the
cylinder kit onto the shaft. While holding the shaft still, slightly rotate the cylinder block kit to help
start the shaft splines into the ball guide and align it with the block splines. When the cylinder block
kit slides completely over the shaft splines, reposition the unit with the flange facing downward.

Valve plate and Endcap
1. Clean the valve plate (B070) and endcap (J020). Install the timing pin (J050) in the endcap and verify
that it is properly oriented with the split facing into or out of the slot in the valve plate. The timing pin
should be installed 3.6 ± 0.25 mm [0.14 ± 0.01 in] above the endcap surface. Apply a liberal amount of
assembly grease to the backside of the valve plate surface to hold it in position. Install the valve plate
over the timing pin, check valve, and bearing cup.
2. Using assembly grease to hold seals, install the endcap to the housing. Ensure that seals remain
properly seated and are not pinched during assembly. Install and torque endcap screws at 47.5 to 61
N•m [35 to 45 lbf•ft], using the criss cross pattern, and retorque the first screw to ensure proper torque
retention.
