LATER
EARLIERRemove Fuel Transfer Pump
1. Disconnect fuel lines (1) and (2) from the fuel transfer pump. Put plugs and caps in the openings. 2. Remove two bolts (3) that hold the fuel transfer pump to the fuel injection pump drive.3. Remove fuel transfer pump (4).Install Fuel Transfer Pump
1. Put fuel transfer pump (1) in position so the shaft is in alignment with the groove in the fuel injection pump drive. Install the bolts that hold it. 2. Remove the plugs or caps from the openings. Connect fuel lines (2) and (3) to the fuel transfer pump.3. Remove the air from the fuel system. See PRIMING THE FUEL SYSTEM in LUBRICATION AND MAINTENANCE GUIDE.Disassemble Fuel Transfer Pump (Earlier)
start by: a) remove fuel transfer pump 1. Remove six bolts (1) that hold the transfer pump cover to transfer pump body. Remove the cover.2. Remove the plug (2), seat, spring and fuel bypass valve from cover. 3. Remove the gear (5) and shaft assembly (4) from the body (3). 4. Remove the seals (6) from the body. 5. Use tooling (A) to remove the bearing from the body.Assemble Fuel Transfer Pump (Earlier)
1. Use tooling (A) to install bearing into body.2. Use tool (B) to install inner seal in body. Install seal with lip of seal in the direction of the gears. 3. Use tool (C) to install outer seal in the body. Install seal with lip of seal toward the outside. 4. Install tool (D) on to shaft assembly (1) and install shaft assembly into body.
Tool (D) must be used to install shaft assembly. The shaft will cause damage to seals if it is not used.
5. Install idler gear (2) in the body. 6. Install fuel bypass valve (3), spring (4), seat (5), and plug into cover.7. Put a thin amount of 8S6747 Aviation Type Permatex on face of body.
Do not let Permatex get into the pump body.
8. Put the cover (6) in position on the body and install the six bolts. After tightening cover to body, the gear and shaft assembly must turn freely.end by: a) install fuel transfer pump
