1.6.3 Cylinder Liner

block. Refer to Section 1.0 for the specified piston-to-liner clearance.
NOTE: Do not modify the surface finish in a new service cylinder liner. Since the
liner is properly finished at the factory, any change will adversely affect the seating
of the piston rings.
Fitting Cylinder Liner in Block Bore
1. Wipe the inside and outside of the liner clean and make sure the block bore and counterbore are clean so the liner
flange will seat properly. Then slide the liner into the block until the flange rests on the bottom of the counterbore in the
block.
CAUTION: Do not drop or slam the liner flange against the bottom of the
counterbore in the block.
2. Tap the liner lightly with a soft hammer to make certain the liner flange seats on the bottom of the counterbore.
3. Clamp the liner in place with hold-down clamp J 21793 and measure the distance from the top of the liner flange to
the top of the block with dial indicator set J 22273 (Fig. 7). The top of the liner flange should be .0465" to .0500" below
the top of the block, and there must not be over .0015" difference in depth between any two adjacent liners when
measured along the cylinder longitudinal center line. If the above limits are not met, install the liner in another bore and
recheck, or use a new liner.
4. Matchmark the liner and the cylinder block with chalk or paint so the liner may be reinstalled in the same position in
the same block bore. Place the matchmark on the engine serial number side of the block (In-line engine),

5. Remove the hold-down clamp and the cylinder liner.
Install Piston and Connecting Rod Assembly
1. With the piston assembled to the connecting rod and the piston rings in place -as outlined in Sections 1.6 and
1.6.1, apply Cindol 1705 oil to the piston, rings and the inside surface of the piston ring compressor J 6883.
NOTE: Inspect the ring compressor for nicks or burrs, especially at the nori-tapered
inside diameter end. Nicks or burrs on the inside diameter of the compressor will
result in damage to the piston rings.
