Table 9-5. Cylinder Liner Counterbore Shims
Just prior to installation, lubricate the crevice seal (30) and packings (28 and 29) with dean
lubricating oil, MIL-L-9000.
(6) Install the crevice seal (30) on the liner (27). Be sure the seal is seated squarely and firmly on the liner and the
chamfered edge faces toward bottom of liner.
To avoid coolant leaks and subsequent engine damage, do not over stretch or twist the
packings during Installation, and be careful to avoid cutting or nicking the packings on sharp
Install the top (black) packing (29) in the top groove of the liner (27) next to the crevice seal (30).
Install the bottom (red) packing (28) in the lower groove of the liner (27).
Observe the mold marks on the packings (28 and 29) to be sure the packings are not twisted. Straighten the
packings as required.
Apply 1/16 inch bead of silicone 3801048 to lower flange of cylinder liner (27). Lubricate the liner bore in the
cylinder block (58) with dean lubricating oil, MIL-L-2104, and install the liner (27) in the bore. Push the liner down
carefully by hand until the packings (28 and 29) enter the lower bore in the block. If difficulty is encountered,
remove the liner and check for improper seal or packing installation.
With the liner (27) firmly seated in the bore by hand, use liner installation tool 3375422, and complete the liner
installation as follows:
Position plate 3375424 on top of the liner (27).
(b) Center the bridge assembly 3375423 over the plate 3375424 and secure it with cylinder head capscrews.
To avoid damage to the tool, liner, or cylinder block, do not tighten the bridge center bolt over
50 pound-feet (68 newton-meters) when seating the liner.
Tighten the center bolt on the bridge assembly until the liner is seated in the bore. Do not exceed a torque
of 50 pound-feet (68 newton-meters) on the bridge center bolt.
Remove liner installation tool 3375422.
