Before you start

  • When the blower wheel has been removed there is danger of this heavy weight being dropped on toes or fingers.

Procedure

  1. Remove the blower wheel through bolt.
  2. Remove the thick washer on the through bolt.
  3. Reinstall the through bolt (the center bolt of the puller will push against the through bolt and protect crankshaft threads).
  4. Fasten the puller screws with sufficient thread in the blower wheel to prevent damage to the threads.
  5. Secure the wheel in position by inserting a large screwdriver or wood block to prevent the wheel from turning.

Tools required

  • Puller 420-0100
  • Large screwdriver or wood block
