1. Install the inner seal in the body with tool (A). Install the outer seal with tool (B). The lip of the inner seal must be toward the pump gears. The lip of the outer seal must be toward the outside. 2. Install key (1) and drive gear (2) on the shaft. 3. Install O-ring seal (4) and idler gear (3) on the body.4. Install body (5) on the housing. Install the bolts that hold the body to the housing. 5. Put sleeve (6) in position on the camshaft. The timing pin must be in position ithe camshaft to keep the camshaft from turning during assembly.6. Install the sleeve on the camshaft with tooling (C).
Do not hit the sleeve with a hammer to install it. This will put end force on the camshaft and cause damage to the other components in the pump housing.
7. The end clearance of the camshaft must be .023 .018 in. (0.58 0.46 mm) after sleeve (6) is installed.end by: a) install fuel injection pump housing and governorRemove Fuel Injection Pumps (Later Sleeve Metering Fuel System)
Before removal of the fuel injection pumps, clean the outer surface of the fuel injection pump housing.
1. Remove bolts (1) that hold cover (2) in position. Remove the cover.2. Remove the spring from the bypass valve. Do not loosen screws (3) that hold the levers when the fuel injection pumps are removed or installed. If the levers are moved, the fuel pump adjustment will be changed.3. Remove the fuel injection pumps with tool (A). The sleeve on the plunger will slide off the lever as the fuel injection pump is removed.Install Fuel Injection Pumps (Later Sleeve Metering Fuel System)
1. Put the fuel injection pump in the bore of the fuel pump housing. Make sure the fuel injection pump (1) is clean and free of dirt and foreign material.2. The sleeve (2) will be engaged with the lever when installed correctly.
If the levers have been moved on the shaft, the fuel pump adjustment must be made. (See TESTING AND ADJUSTING).
