  1. Before removing the crankshaft, measure the crankshaft end play using the following procedure:
    1. Reinstall the lower crankcase.
    2. Place a dial indicator at the crankshaft nose.
    3. Gently force the crankshaft to the extreme front and rear positions with a pry tool while monitoring the movement of the dial indicator.
    4. The crankshaft end play should not exceed 0.05-0.5 mm (0.002-0.020 in).
    5. If the specifications are exceeded, replace the thrust bearing.
    6. If a new thrust bearing does not bring the tolerances within specification, replace the crankshaft.
    7. Remove the lower crankcase.
  2. Locate or fabricate two V-blocks to support the crankshaft.
