(24.6 0.5 mm) from the bottom surface of body (3) and with the lip of the seal toward bearing (2) as shown.4. Install lip type seal (5) with tooling (A). Install seal (5) until it is .56 .02 in. (14.2 0.5 mm) from the bottom surface of body (3) and with the lip of the seal away from bearing (2) as shown.5. Install bearing (7) even with the surface on the drive gear end of pump body (3) with tooling (A).6. Put a small amount of clean engine oil on O-ring seal (8) and install the seal on the pump body. 7. Put the seal guide, part of tool group (B), in position on shaft assembly (9) as shown. Put clean diesel fuel on the seal guide and on the lips of seals (5) and (6). Put shaft assembly (9) in position in the pump body. 8. Install the key, gear (10) and nut (11) on shaft assembly (9).
