Piston, Liner, Rings, Rod and Rod Bearings.
Inspect cylinder liner in block. If any signs of wear are present, remove liner for further inspection and repair.
It is very important to follow proper method when removing cylinder liner. Do not attempt to push liner out by
inserting a bar in the liner ports and rotating crankshaft. Piston liner damage will result.
Use tool set J24563-A to pull liners. Ease the lower shoe and bolt assembly into liner. Place shoe on bottom
edge of liner parallel with bore. Hold shoe assembly in upward pulling position.
Place upper shoe with flat over threaded end of bolt. Tighten nut on bolt making sure both top and bottom
plates are square and in position on liner.
Place bridge assembly over the bolt and upper shoe.
Position thrust bearing and bolt through bridge assembly.
Turn bolt clockwise and withdraw liner from block. Remove tool set from liner.
Remove and tag liner insert from counter-bore of block. This will save time during installation.
(8) If original sleeve is to be reused, remove and discard both liner seal rings from grooves in block bore.
Repeat procedure to remove remaining liners.

Dry cleaning solvent P-D-680 (safety or Stoddards solvent) is potentially dangerous. Avoid repeated and
prolonged breathing of vapors and skin contact with the liquid. Do not use near open flame, arcing
equipment or other ignition sources. Always wear eye protection and protective clothing. The flash point of
P-D-680 is 100 to 138 deg. F (30 to 59 deg. C).
Death or serious injury could occur if compressed air is directed against the skin. Do not use compressed
air for cleaning or drying unless the pressure Is/has been reduced to 30 psi (2.11 kg/cm2) or less. When
working with compressed air always use chip guards, eye protection and other personal protective
