Measure cylinder liner height as follows:
If liner height was not checked when liners were removed, refer to paragraph 3-34.6., step e, or a new liner
is being installed in a new or used cylinder block, liner height must be checked.
Be sure liner bore in cylinder block is clean.
Install liners without -rings and packing.
Liner should rotate smoothly by hand when installed. If not, remove liner and polish bottom liner pilot
bore in cylinder block with emery cloth. Use a shop towel or other suitable means to collect debris
when polishing bore.
Install liner with its mark toward the front of the engine. Secure with capscrews and washers. Tighten
screws to 50 ft-lbs (68 Nm).
Using gage (JDG451) and dial indicator, measure each liner height in four places, at approximately 1, 5, 7,
and 11 o'clock positions as viewed from the rear of the engine (flywheel end). Record all measurements.
Liner height specification is 0.0004 to 0.004 inch (0.01 to 0.10 mm). Maximum permissible difference
between readings within one cylinder or between adjacent cylinders is 0.002 inch (0.06 mm).
If liner height is above specification, check cylinder block for burrs on liner support flange or incorrect
Only one shim (1, FIGURE 3-161) is allowed per cylinder. If liner requires more than one shim,
install either a new liner or engine block.
If liner height is below specification, install one liner shim on bottom of liner flange. Two sizes of shims are
0.002 inch (0.05 mm) Part No. CD15466.
0.004 inch (0.10 mm) Part No. R65833.
Deglaze cylinder liners as follows:
Fabricate cylinder liner holding fixture (FIGURE D-3, Appendix D).
Secure cylinder liner in holding fixture.
Use honing oil (MB-30) along with deglazer when deglazing liners.
