Install the pilot ring and the locating pin in the cylinder block (refer to Fig. 25).
Figure 25.
Figure 27.
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. 26).
Assemble the bearing race shim (if required) and locating pin in the end cap. Lubricate the end cap face with
clean hydraulic oil. Install the valve plate so that the milled slot locates over the pin and the center bore fits
over the protruding bearing race.
Check the valve plate to be certain it is a motor valve plate (has 4 tapered slots) (refer to Fig. 27).

Figure 28.
Place the end cap gasket on the housing, being certain the locating pins are in place, then install the end cap
and valve plate. Hold the valve plate so it does not drop off during assembly. The end cap and gasket will only
align with housing mounting holes in one position (refer to Fig. 28).
Install two end capscrews and alternately tighten them until the internal spring has compressed far enough for
the end cap to rest on the housing. Install the remaining screws (refer to Fig. 29).
