NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.



NOTICE

Every time that the crankshaft seal is removed from the wear sleeve, a new wear sleeve and crankshaft seal must be installed.


  1. For 3520 engine crankshafts not using the oil fed damper remove the oil plug on the front face of the crankshaft.

  2. Inspect the seal and mating hardware for any obvious issues or contamination. Clean any oil that is on the housing.

  3. Check for the correct sleeve and chamfer direction.

  4. Clean the outer diameter of the crankshaft and the inner diameter of the new wear sleeve with Tooling (G).

  5. Apply Tooling (H) to the outer diameter of the crankshaft and the inner diameter of the new wear sleeve.


    NOTICE

    If the crankshaft seal and the wear sleeve come apart during installation, the crankshaft seal and the wear sleeve must be replaced.


    Note: The front crankshaft seal and the wear sleeve cannot be interchanged with the rear crankshaft seal and the wear sleeve.


    NOTICE

    Do not place engine oil on the crankshaft seal for installation. Lubrication of the crankshaft seal can give a false indication of leakage at a later time.

  6. Install Tooling (D) onto the crankshaft.

  7. Center and press the crankshaft seal over the locator

  8. Place front seal (1) and wear sleeve (2) onto Tooling (D).

  9. Place Tooling (E) onto Tooling (D). Apply Tooling (J) onto the face of the washer on Tooling (F). Install Tooling (F) onto Tooling (E). Tighten the nut until Tooling (E) contacts Tooling (D).

  10. Loosen Tooling (F). Rotate Tooling (E) 90 degrees and tighten the nut until Tooling (E) contacts Tooling (D).

  11. Repeat Step 10 four times rotating Tooling (F) in the same direction.

  12. Remove the Tooling from the crankshaft.

  13. For 3520 engine crankshafts not using the oil fed damper, install the oil plug on the front face of the crankshaft.

Installation Procedure For Seals 436-1478 and 436-1479


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.



NOTICE

Do not place engine oil on the crankshaft seal for installation. Lubrication of the crankshaft seal can give a false indication of leakage at a later time.


Note: Ensure that there are no imperfections on the mating surfaces of the crankshaft, the installation tooling, or on the sealing surface of the crankshaft. Surface imperfections can distort the seal during installation and will cause the seal to malfunction.

  1. Using Tooling (K), install front seal (1) as outlined in the following steps:

    1. Install pilot (K1) to the crankshaft and install bolts (K2).

    2. Position front seal (1) onto pilot (K1).

    3. Install driver (K3) onto the shaft of pilot (K1). Mark driver (K3) at the 12 O' CLOCK position. Install bearing (K4) and nut (K5).

    4. Tighten nut (K5) until the base of driver (K3) contacts the skirt of pilot (K1). Loosen nut (K5) and rotate driver (K3) 180 degree. Retighten nut (K5) until driver (K3) contacts the skirt of pilot (K1).

  2. Remove Tooling (K).

  3. For 3520 engine crankshafts not using the oil fed damper, install the oil plug on the front face of the crankshaft.

End By:

  1. Install the vibration damper.
