Lubricating Oil Pump Fits and Clearances8-13.OIL PUMP ASSEMBLY. See Figure 8-4.a.Install the lubricating pump shaft and gear (45 and 44) into the lubricating pump body (47).b.Support the lubricating pump shaft (45) and press the lubricating pump drive gear (43) on the shaft until it isflush with the end of the shaft.c.Install the lubricating pump shaft and gear (42 and 41) into the lubricating pump body (47).d.Position a new lubricating pump gasket (40) on the pump body, and install the cover (39), hexagon headcapscrews (37), and lockplates (38) and tighten to 30 to 35 pound-feet (41 to 47 newton-meters) torque.Bend the tabs on the lockplates to secure the capscrews.e.Check the shaft end clearance (3, Figure 8-7). The end clearance shall be 0. 004 to 0. 007 inch (0. 10 to 0.18 mm). If the end clearance is incorrect, replace the cover (39, Figure 8-4).f.Position the relief plunger (36), relief spring (35), and plain washer (34) into the pressure relief housing (30).Secure with the retaining pin (33) and roll pin dowel (32).CAUTIONIt is possible to install the of oil transfer tube (23) in a reverseposition (wrong end to the lubricating pump). Whenever thishappens, the support bracket (6) for the oil suction tube (9) will notfit. Install the long end of the transfer tube to the pressure reliefhousing (30) connection on the lubricating oil pump.g.Lubricate the supply tube seal (20) with clean engine lubricating of MIL-L-2104, or equivalent, and position iton the long-bend end of the transfer tube (23). Use a new relief gasket (31) and install the pressure reliefhousing assembly (30) and transfer tube (23) with supply tube seal (20) to the lubricating pump cover (39)with capscrews (21) and lockplates (22).
