NOTE

Shims (1) are used to set pressure relief valve. The

number of shims may differ from pump to pump. Some

pumps may have no shims.

Save all shims in new parts

kit, even if pump you are working on had no shims.

Shims will be used later for pump test and adjustment.

Relief valve spring (2) and plunger (3) come in a parts

kit. The kit also has a new retaining pin (4), one of

two types of spring retainer (5), and shims (1). If any

of these parts are damaged, all should be changed. If

kit has two plungers, the longer one is for this pump.

Some early model oil pumps used washer (6) instead of one of two types of

spring retainer (5) to hold in relief valve plunger (3) and spring (2). If

working on pump with washer, threw away washer and get a parts kit

with new spring retainer, retaining pin (4), plunger, spring, and shims (1).

WARNING

Dry cleaning solvent is flammable. Do not use near

an open flame. Keep a fire extinguisher nearby when

solvent is used. Use only in well-ventilated places.

Failure to do this may result in injury to personnel

and damage to equipment.

Check that spring retainer (5), spring (2), and plunger (3) have no

cracks or burrs.

Fix small burrs with a fine mill file or crocus cloth

dipped in dry cleaning solvent.

If spring retainer (5), spring (2) or plunger (3) are cracked or badly

damaged, throw away spring retainer, spring, plunger, retaining pin (4),

and shims (1) and get new ones.
