(11) Use a wrench to turn push screw until bottom of liner flange touches special ring. Remove
installation tool.
NOTE
New cylinder liners can be 0.0002 to 0.0006 inch (0.005 to 0.015 mm) smaller than
the minimum specification due to the lubrite coating.
(12) Use dial bore gauge to measure inside diameter at top, bottom, and middle of liner. Take
two measurements 90 degrees apart at each location. Verify m asurements are between
e
6.2495 and 6.2510 inch (158.737 and 158.775 mm). Also verify that two measurements at
top are within 0.003 inch (0.076 mm) of each other and two measurements at bottom are
within 0.002 inch (0.05 mm) of each other.
NOTE
A new bead of sealant must be applied if liner is removed and re-installed.
(13) If measurements are not within specification, remove liner, check for twisted preformed
packing and out of round liner.

CAUTION
Parts must be clean and free of nicks and burrs to accurately measure the
protrusion.
(15) Position gauge block so that indicator needle contacts liner flange on the outside of the
sealing bead (FIG. 4-91).
(16) Gently push indicator needle down until it touches the liner. Turn gauge until the "O" is
aligned with the indicator needle of the dial. Repeat step to ensuredial reads "O" when
needle touches the liner.
(17) Raise indicator needle. Move gauge block until indicator needle is over the cylinder block.
Gently push indicator needle until it touches the block. Verify dial reads between 0.006 and
0.008 inch (0.15 and 0.20 mm).
