NOTE:
The damper only needs to be withdrawn along the crankshaft nose by approximately 2mm before
removing the puller. The damper will then either be loose or only require a sharp tap with a mallet to
release it from the split locking ring.
Remove the damper from the crankshaft. 1. Install adaptor 303-191-02 to the damper extractor tool 303-588 (Use the socket head screws provided with the puller).
2. Locate the thrust button into the end of the crankshaft; the O-ring holds it in place.
 Assemble the puller to the damper.
 Extract the damper from the crankshaft.
9. Remove the puller components from the damper. Remove the thrust button from the end of the crankshaft.
