1.6.3 Cylinder Liner
black 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 Range rests on the bottom of
the counterbore in the block.
Do not drop or slam the liner flange
CAUTION:
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 2 1793 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
Fig. 8 - Installing Piston and Connecting Rod
limits are not met, install the liner in another bore and
Assembly in Ring Compressor and Cylinder
recheck, or use a new liner.

4. Matchmark the liner and the cylinder block with
same position in the same block bore. Place the
chalk or paint so the liner may be reinstalled in 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 non-tapered Inside
diameter end. Nicks or burrs on the inside
