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. 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.
