    NOTE: Refer to FASTENER NOTICE .
    1. 2.1. Attach the J 38196  to the crankshaft by hand, or tighten the attaching screws.

      Tighten 

      Tighten the screws to 5 N.m (54 lb in).

    2. 2.2. Turn the T-handle of the J 38196  so that the collar pushes the seal into the bore. Turn the handle until the collar is tight against the case. This will ensure that the crankshaft rear oil seal is seated properly between the crankshaft and the crankshaft rear oil seal housing.

  3. Install the engine flywheel. Refer to Engine Flywheel Replacement .
  4. Check and fill the crankcase as necessary.
