start by:a) remove fuel injection pump housing and governor 1. Install the fuel injection pump housing on tool (A).2. Remove bolts (1) and governor housing (2). Later fuel injection pump housings have a thrust washer for the fuel injection pump camshaft. The thrust washer is behind the flange for the flyweights on the camshaft. To hold the thrust washer in place, governor shaft (3) and the camshaft must be held in toward the fuel transfer pump any time sleeve (4) is removed. 3. Remove the plug from the cover and install tool (B) in the hole as shown. Turn the injection pump camshaft until tool (B) can be pushed into the groove (slot) in the camshaft. Any time the drive sleeve is removed from the camshaft a new one must be installed. The camshaft has serrations (splines) that cut grooves into the drive sleeve when it is installed to give a positive drive connection. If a formerly used drive sleeve is installed again, it can slip (slide around) on the camshaft. 4. Install tool (C) in the threads of sleeve (4). Tighten the bolt until the sleeve can be removed.5. Remove four bolts (5) and fuel transfer pump body (6) from the housing. 6. Disconnect drain line (7) from the fitting on the back of the fuel transfer. 7. Remove gear (8) and O-ring seal (9) from the pump body. 8. Remove seals (10) from the pump body. 9. Remove drive gear (11) and the key from the camshaft.Install Fuel Transfer Pump
