Disassembly (Fig. 56)
1. Plug pump ports and clean the outside of the pump
thoroughly. After cleaning, remove plugs and drain any
oil out of the pump.
2. Use a marker to make a diagonal line across the
front plate, front body, adapter plate, rear body and back
plate for assembly purposes (Fig. 57).
IMPORTANT: Avoid using excessive clamping
pressure on the pump housing to prevent distorting
the housing.
