Grooving in the plate, 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).

gasket before assembly.

seat of housing (1).

block (31) to end cap (2) with clean oil prior to

installation.

end cap bolts (4), push down on end cap (2)

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 22 (Torque
