(1)
Using cylinder liner tool, remove cylinder liner (1) from cylinder block (2).
WARNING
Dry cleaning solvent PD-680 used to clean parts is potentially dangerous to personnel and property. Avoid
repeated and prolonged skin contact. Do not use near open flame or excessive heat. Flash point of
solvent is 100-138°F (38-60°C)
(2)
Clean cylinder liner with dry cleaning solvent, and dry thoroughly.
(3)
Inspect liner for cracks, scoring, flange irregularities, out-of-round, taper, inside diameter and outside diameter.
(4)
If liner is cracked or excessively scored, replace liner.
NOTE
After removing liners from block and prior to installing liners, always store them in an upright position until
ready for use. Liners left on their side for any length of time can become egg-shaped and distorted,
making installation in cylinder bores difficult or impossible.
Counterbore must be .247-.248 in. (.627-.629 cm) in depth and must not vary more than .001 in. (.002
cm) in depth.
(5)
Wipe inside and outside of liner, clean and make sure block bore and counterbore are clean.
(6)
Install cylinder liner (1) in cylinder block (2).
(7)
Clamp liner in place with hold-down clamp.
NOTE
Top of liner flange must be .002-.005 in. (.005-.012 cm) above top surface of block. Liner height above
the block between the liners must not be over .001 in. (.002 cm).
(8)
Measure distance from top of liner flange to top of cylinder block, if measurement is not within the specified
limits, shim liner.
NOTE
Liner shims .0015 and .003 in. (.0038 and .007 cm) thick are used to adjust the height of liners to
specified .002-.005 in. (.005-.012 cm) above block.
Liner must be raised only enough to permit installation of shim under liner flange.
