Figure 60.
Install the pilot ring in the bearing plate and the locating pin in the cylinder block. Install the bearing plate so
that the milled slot locates over the pin and the pilot ring fits in the center bore of the cylinder block. After
installation, lubricate the exposed surfaces with clean hydraulic oil (refer to Fig. 61).

Figure 62.
Assemble the bearing race, shim (if required), and locating pin in the end cap. Check the valve plate to be
certain it is a pump valve plate (has two tapered slots) and that it is for correct rotation (slots point away from
direction of rotation) (refer to Fig. 62).
Lubricate the end cap face with clean hydraulic oil. Install the valve plate so that the slot locates over the pin
and the center bore fits over the protruding bearing race. Place the end cap gasket on the housing, being
certain the locating pins are in place, then install the O-ring in the counter bore in the housing (refer to Fig. 63).
Figure 63
Install the end cap and valve plate, holding the valve plate so it does not drop off during assembly (refer to Fig.
64).
