TM 9-2815-210-34-2-2 FRAME 4 1. 2. 3. 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.
