Install bearing (2) in body assembly (1) with tool group (A). Make sure the face of the bearing is not beyond surface (D). 3. Install the idler shaft in body assembly (1) until the face of the shaft is .371 .003 in. (9.42 0.08 mm) above surface (D). 4. Put a thin layer of 8S6747 Gasket Sealer (Permatex No. 3) on the outside diameter of seal (4). Install the seal in cover assembly (3) with tool group (A). Make sure dimension (E) is .45 in. (11.4 mm). Make sure the rubber lip of the seal is toward surface (F). Put a light amount of clean diesel fuel on the rubber lip of the seal.5. If necessary, make a replacement of the ferrules in cover assembly (3) so they extend .25 in. (6.35 mm) above surface (F). 6. Install plunger assembly (4), spring (6), the gasket and plug (5). Tighten the plug to a torque of 27 3 lb.ft. (38 4 N m). 7. Put clean oil on shaft assembly (7) and install it in the body assembly. 8. Put clean oil on idler gear (8) and install it in the body assembly.9. Put a thin layer of 8S6747 Gasket Sealer (Permatex No. 3) on the contact surfaces of the cover and body assemblies.
Make sure the Permatex does not get on the inner surfaces of the transfer pump.
