  1. Support crankshaft (1) on a suitable stand.

  2. Remove Allen head screws (2) from the crankshaft timing ring (3). Do not reuse the allen head screws.

  3. Carefully remove crankshaft timing ring (3) from crankshaft (1). Do not reuse the crankshaft timing ring.

    Note: Ensure that seal surface (4) of the crankshaft is not damaged when the crankshaft timing ring is removed.

    Note: Do not remove dowel (5) from crankshaft (1) unless the dowel is damaged.

Installation Procedure


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


  1. Ensure that the flange for the crankshaft timing ring on the crankshaft is clean and free from damage.

  2. Support crankshaft (1) on a suitable stand.

  3. If dowel (5) was removed, install a new dowel to crankshaft (1).

  4. Position new crankshaft timing ring (3) on the crankshaft with the teeth toward the crankshaft web. Align the hole in crankshaft timing ring (3) with dowel (5) in the crankshaft. Carefully install crankshaft timing ring (3) to the crankshaft (1).

    Note: Ensure that seal surface (4) on the crankshaft is not damaged when the crankshaft timing ring is installed.

  5. Install new Allen head screws (2). Tighten the Allen head screws to a torque of 9 N·m (80 lb in).

End By:

  1. Install the crankshaft. Refer to Disassembly and Assembly, "Crankshaft - Install ".

  2. If a crankshaft wear sleeve was previously installed to the crankshaft, install a new crankshaft wear sleeve. Refer to Disassembly and Assembly, "Crankshaft Wear Sleeve - Install".
