Usage:
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).
NOTE: 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.
NOTE: 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
NOTE: The fuel injection camshaft must be held in toward the fuel transfer pump during installation of the fuel transfer pump parts to hold the camshaft thrust washer in its counterbore. The thrust washer will be damaged when the sleeve is installed on camshaft if it is not in the correct position.
1. Install key (1) and drive gear (2) on the shaft.
2. Put No. 3 Aviation Permatex on the outside diameter of seals for body (3).
3. Use tooling (B) to install the first seal in the body with the lip down and the second seal with the lip up. Install the first seal to a depth of .453 in. (11.51 mm) and the second seal to a depth of .030 in. (0.76 mm).
4. Remove the extra Permatex from the body and seals after installation. Be sure the drain hole between the seals is open.
5. Install O-ring seal (4) and gear (5) on the body.
6. Install tool (C) in the end of the fuel injection pump camshaft. Connect drain line (6) to the fitting on the back of the body and put the body in position on the fuel injection pump housing. Install the bolts that hold the body in place.
7. Install tool (E) in the camshaft so it will not turn.
8. Put a new sleeve (7) on the camshaft.
NOTE: A new drive sleeve must be installed because a used drive sleeve can slip (slide around) on the camshaft.
9. Tighten the sleeve into position on the shaft with the 4B4280 Washer of tooling (D) approximately .25 in. (6.4 mm). Tighten the sleeve the remainder of the way with the 9N5022 Washer until the sleeve is at the bottom. This is the washer which is on the tachometer drive shaft.
| NOTICE |
|---|
Do not hit the sleeve to install. Damage to the governor will be the result. |
10. Use a feeler gauge to check the end play of the camshaft after the sleeve is installed. The end play of the camshaft must be .023 ± .018 in. (0.58 ± 0.46 mm).
11. Be sure the governor springs and gasket are in position on governor housing (8). Install the governor housing on the fuel injection pump housing.
12. Be sure bolt (9) has the washer and O-ring seal on it when installed.
13. Remove the fuel injection pump housing from tool (A).
