Measure cylinder liner height above cylinder block as follows:
Ensure that cylinder liner bore in cylinder block and top deck of cylinder block are
Install cylinder liner in cylinder liner bore without O-rings and packing.
Insure that cylinder liner rotates smoothly by hand. If cylinder liner does not rotate
smoothly by hand, remove cylinder liner and polish cylinder liner bore with emery
cloth or Brush. Use shop towel or other suitable means to collect debris when
polishing cylinder liner bore.
Position cylinder liner with liner mark towards front of engine. Secure with
capscrews and washers, refer to paragraph 5.4.5. Torque capscrews to 50 lb-ft (68
Using Piston and Liner Height Gauge and Dial Indicator, measure cylinder liner
height above cylinder block at 1, 5, 7, and 11 oclock positions as viewed from back
of engine. Record measurement. Compare cylinder liner height above cylinder
block with specifications given in Table 5-11.
If cylinder liner height above cylinder block is above specification, check cylinder
block for burrs. Repair or replace as required.
