Disassembly

2. Using a 10 mm wrench, loosen the end cap bolts

(4) evenly.

3. Hold the end cap (2) in place and remove the

four end cap bolts (4).

Inspection

1. Inspect the end cap (2) body for damage, nicks

or unusual wear patterns. Replace if necessary.

2. Inspect the running surface (side that contacts

the cylinder block) of the end cap (2). The

running surface may show evidence of minor

abrasive rings, this is normal.

Grooving in the end cap, or material transfer that

is evident when the surface is checked by

dragging a fingernail across it, would be cause

for replacement of the end cap (2).

3. Replace the housing gasket (5) with a new

gasket before assembly.

Assembly

1. Install housing gasket (5) into gasket seat of

housing (1).

2. Lubricate the cylinder block (25) to end cap (2)

mating surface with clean oil prior to installation.

3. Install end cap (2). Before installing the four

end cap bolts (4), push down on end cap (92)

verifying alignment and insuring that the

cylinder block pistons spring back and forth.

Install end cap bolts (4). Tighten to the correct

torque value. See Table 2, page 56 (Torque

Values).
