Procedure:
CAUTION
Be sure to put on safety goggles in carrying out the following items of work
being in danger of injury to eyes.
- If the liners are not to be removed, they can be deglazed in place, either
by hand or by a honing machine. If done by hand, a fine (No 40) emery paper
should be used, and sanding should be in a circumferential direction, NOT in
an up-and-down direction.
- Close the bottom of the liner with plastic or similar material to prevent
abrasive material from falling into the crankshaft and sump areas while
sanding.
4.3.3 Measurement of Liner Bore
- After deglazing, measure the liner bore using a dial indicator or
micrometer. Measuring points are described in the Clearance and Wear Table.
If the measured values exceed the maximum wear limits, the liner must be
replaced.

following:
・
Improper seating between the liner flange and the top surface of the
block.
・
Improper installation of the o-ring seals at the bottom of the liner.
・
Excessive liner wear (if out-of-roundness still exceeds 0.2 mm after
checking the above, a new liner should be installed.
