spring retainer (9) to hold pressure relief valve spring

(4) and plunger (5) inside pump.

Shims (6) are used to set pressure relief valve. Num-

ber of shims inside pressure relief valve will be different

Some pumps have no shims.

there is a copper gasket (3) under threaded cap, take it out and throw it

away.

Take out pressure relief valve spring (4), plunger (5), and shims
