Before you start

  • Do not hit the sleeve to install. Damage to the governor will be the result.
  • A new drive sleeve must be installed because a used drive sleeve can slip on the camshaft.
  • The camshaft must be held in toward the fuel transfer pump during installation to hold the camshaft thrust washer in its counterbore; the thrust washer will be damaged if not in the correct position.

Procedure

  1. Install key (1) and drive gear (2) on the shaft.
  2. Put No. 3 Aviation Permatex on the outside diameter of the seals for body (3).
  3. Use tooling (B) to install the first seal lip down and second seal lip up.
  4. Remove extra permatex from the body and seals after installation. Be sure the drain hole between the seals is open.
  5. Install tool (C) in the end of the fuel injection pump camshaft. Connect drain line (6) and put the body in position on the housing. Install the bolts.
  6. Install tool (E) in the camshaft so it will not turn.
  7. Put a new sleeve (7) on the camshaft.
  8. Tighten the sleeve into position on the shaft with the 4B4280 Washer of tooling (D) approximately 6.4 mm (.25 in.). Tighten remainder with 9N5022 Washer until sleeve is at bottom.
  9. Use a feeler gauge to check the end play of the camshaft after the sleeve is installed.
  10. Remove tool (E) from camshaft.
  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).
