Remove check valve (13).Assemble Fuel Transfer Pump
1. Install bushing (4) in body (3) with Tooling (B). The bushing must be .80 .50 mm (.031 .020 in) below the (gear) surface of the body.2. Install the check valve in the body with Tooling (A).3. Install lip-type seal (5) with Tooling (C). Install the seal until it is 26.19 .13 mm (1.031 .005 in) from the bottom (drive gear) surface of body (3) and with the lip toward bushing (4) as shown.4. Install lip-type seal (6) with Tooling (D). Install the seal until it is 14.2 0.5 mm (.559 .020 in) from the bottom (drive gear) surface of body (3) and with the lip away from seal (5) as shown.5. Install bearing (7) in body (3) with Tooling (E). The bearing must be even with the bottom (drive gear) surface of the pump body. 6. Heat gear (8) to a maximum temperature of 315° C (600° F). Install gear (8) on shaft (11) until dimension (X) is 49.71 0.25 mm (1.957 .010 in).7. Install the drive shaft and gear in body (3). Install the key, gear (10) and nut (9). Tighten the nut to a torque of 30 7 N m (22 5 lb ft).8. Install idler gear (12) in body (3).9. Install lip-type seal (2) with Tooling (C). Install the seal until it is 22.61 .05 mm (.890 .002 in) from the top surface of cover (1) with the lip toward the inside as shown. 10. Install plunger (14) (bypass valve), spring (15) and seal and plug (13) in pump cover (1). Tighten plug (13) to a torque of 37 4 N m (27 3 lb ft).
Do not let the liquid gasket enter the pump during application or assembly.
