Start By:
a. remove engine oil pan
Fluid Spillage Containment
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "Tools And Shop Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of fluids according to local regulations and mandates.
1. Remove bolt (1) and tube (2) from the engine oil pump.
2. Remove three bolts (3) that hold the engine oil pump in position on the block. Remove engine oil pump (4).
NOTE: The following steps are for installing the engine oil pump.
3. Install engine oil pump (4) and the three bolts (3) that hold it in place.
4. Make sure the O-ring seal is in position on tube (2). Install tube (2) on the engine oil pump. Install the one bolt (1) that holds the tube to the engine oil pump.
NOTE: For more detailed information regarding the engine oil pump, see the topic "Engine Oil Pump" in the Specifications Module.

1. Remove the bolt and washer that hold gear (1) in position on the shaft. Remove gear with Tool (A).
2. Remove key (2) from the shaft.
Typical Example.
3. Remove the bolts and retainer (7). Remove spacer (6), spring (5) and plunger (4) from the engine oil pump.
NOTE: The 6N-1030 Engine Oil Pump does not have spacer (6) and retainer (7) is not as shown. It is more a strap than a full cover as shown in the photo.
4. Remove bolts and cover (3).
5. Use Tool (B) to remove two bearings (8) from cover (3).
6. Remove two shaft assemblies (9) from the engine oil pump body.
7. Use Tool (B) to remove two bearings (11) from engine oil pump body (10). Remove two dowels (12) from the engine oil pump body.
Assemble Engine Oil Pump
1. Use Tool (A) to install two bearings (3) in the engine oil pump body. The bearing joint must be within 30 ± 15 degrees of the centerline through the bores, as shown. The bearings must be installed so they are even with face (A).
2. Install dowels (1) and (2) in the engine oil pump body. Install the dowels so they extend 6.40 mm (.252 in) above the surface.
3. Put clean oil on the inside diameter of the bearings in the engine oil pump body and on shafts (4) and (5).
4. Install shaft (4) in the lower section of the engine oil pump as shown. Shaft (4) has the groove (slot) for the key.
5. Install shaft (5).
6. Use Tool (A) to install two bearings (6) in the cover. The bearing joint in the bearing must be 30 ± 15 degrees from the centerline through the bores, as shown.
7. Install the bearings so they are even with face (B). Put clean oil on the inside diameter of each bearing.
Typical Example.
8. Install cover (7) on the engine oil pump body. Install plunger (8), spring (9), spacer (10) and retainer (11) on the engine oil pump. Install the bolts that hold the retainer.
NOTE: The 6N-1030 Engine Oil Pump does not have spacer (10) and retainer (7) is not as shown. It is more a strap than a full cover as shown in the photo.
9. Install key (12) in the shaft.
10. Install gear (13), the washer and bolt (14). Tighten the bolt to a torque of 54 ± 7 N·m (40 ± 5 lb ft).
11. The engine oil pump must turn freely after it is assembled.
