NMWR 9-2815-220 OIL PUMP ASSEMBLY OVERHAUL—Continued 0013 00 ASSEMBLY 1. Refer to WP 0005 00 for general assembly procedures. 2. Assemble oil pump assembly in accordance with TM 9-2815-220-34. 3. Test of the oil pump assembly requires a test bench as shown schematically in Figure 5. Performance test parameters of the oil pump assembly are listed in Table 3. Testing of the oil pump assembly is to be made using SAE 30 weight oil at a temperature between 170-180° F (77-82° C). Also check the pressure pump pressure relief valve. Maximum pressure must not exceed 250 psi (1724 kPa). Table 3. Oil Pump Assembly Test Parameters.
