Sequence of operation

  1. Critically check the seal ring. If necessary, apply new seal rings, coated with acid free grease and slipped over the liner from below. When inserting into the ring grooves, note that the ring should be evenly tensioned round the circumference and that they must not be twisted.
  2. Carefully pull the support ring from below over the cylinder liner, paying attention to seal ring.
  3. Mount traverse onto support ring and turn home the puller screw until the cylinder liner rests firmly in the support ring.
  4. Insert the support ring with cylinder liner with care into the crankcase & cylinder block, paying attention to the correct position of the support ring in relation to the locating collar.
  5. Fit two hexagonal screws.
  6. Detach traverse and two eye bolts, and again measure the liner bore.
  7. After completion of assembly work, unscrew the check screw and with the cooling water pressure being present, check the seal ring for leaks.

Note: If new cylinder liners have been installed, they must be run in according to instructions.
