    Typical example

  1. If the crankshaft gear is a sliding fit on the crankshaft, remove crankshaft gear (1) from crankshaft (2).

    If the crankshaft gear is an interference fit on the crankshaft, use Tooling (A) in order to remove crankshaft gear (1) from crankshaft (2).

  2. If necessary, remove key (3) from crankshaft (2).

    Note: Do not remove the key from the crankshaft unless the key is damaged.

Installation Procedure


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


  1. Ensure that all components are clean and free from wear or damage. If necessary, replace any components that are worn or damaged.

  2. If necessary, install a new key (3) to crankshaft (2).

    Note: The crankshaft gear may be a sliding fit on the crankshaft or an interference fit on the crankshaft.

    ------ WARNING! ------

    Hot parts or hot components can cause burns or personal injury. Do not allow hot parts or components to contact your skin. Use protective clothing or protective equipment to protect your skin.


  3. If the crankshaft gear is a sliding fit on the crankshaft, align the keyway on crankshaft gear (1) with key (3) in the crankshaft. Install crankshaft gear (1) to crankshaft (2).

    If the crankshaft gear is an interference fit on the crankshaft, heat crankshaft gear (1) in an oven to 150° ± 50°C (302° ± 90°F). Align the keyway on crankshaft gear (1) with key (3) in the crankshaft. Install crankshaft gear (1) to crankshaft (2).

    Ensure that shoulder (4) of crankshaft gear (1) is toward the front of the engine.

End By:

  1. Install the front housing. Refer to Disassembly and Assembly, "Housing (Front) - Install".

  2. Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
