Before you start

  • To prevent cylinder liner damage, never use a hammer or other unsuitable device to remove the cylinder liner.
  • If the same cylinder liner is used again, it must be installed at an offset of 90 degrees from its last position.

Procedure

  1. Remove the piston. Refer to section Removal of Piston.
  2. Using a paint pen, mark the position of the cylinder liner in the cylinder block. Mark both the cylinder liner and the block. Then make another set of marks 90 degrees from the first set, in a clockwise direction.
  3. Remove the cylinder liner, using the cylinder liner removal tool (J-45876). Clean and wipe out the inside of the cylinder liner of any oil or coolant. Install the cylinder liner removal tool in the cylinder liner to be removed with bridge resting on deck of cylinder block and lip of tool resting on the top of the cylinder liner. Tighten the lower nut to expand the tool in the cylinder liner. Tighten the upper nut on the tool until the cylinder liner is pulled from the cylinder block. Remove the cylinder liner and tool. Remove the tool from the cylinder liner.
  4. Remove the shim from the block counterbore.
  5. Remove and discard the two O-rings from the block.
  6. Clean the cylinder block sealing areas and inspect for corrosion.
  7. Check the condition of the cylinder liner collar seat. Ensure that the depth of the collar seat is within the specifications listed in the installation tolerances table.
  8. Check the condition of the liner collar seat. Make sure that the depth of the collar seat is within the specifications given.
