Cylinder Sleeve Removal
[212 NC]
SPECIAL TOOL REQUIRED
r
Cylinder Liner/Sleeve Puller PT6435
With early engine production, a crevice seal,
similar to an O-ring, was installed in the groove
located in the outside diameter of the cylinder
sleeve, near the sleeve top. It has been
determined, however, that the crevice seal is not
necessary. Therefore, effective approximately
December 1998, the crevice seal is no longer
used in production engines. Additionally, effective
January 1999, the crevice seal groove in the
cylinder sleeve has been eliminated.
Effective with these production changes, cylinder
sleeve part Nos. 509GC463 and 509GC466 for
service use will not have the crevice seal groove,
and it is recommended that use of the crevice
seal be discontinued in all engine repairs or
rebuilds, whether or not the liner has a crevice
seal groove.
Refer to Figure 125 and Figure 126.
1. Rotate the engine in the stand so that it is
upright (deck surface upward).
2. Use puller PT6435, or equivalent, to remove
the cylinder sleeve (1) from the cylinder
block (4).
3. Position the puller above the sleeve and
guide the puller shaft through the sleeve.
Extreme care must be taken to make sure the
puller shoe is properly aligned in the bottom of
the sleeve to prevent damage to the block.
4. Position the puller shoe so that it catches the
lower lip of the sleeve. Ensure that it does
not extend beyond the outside edges of the
sleeve so it will not come into contact with
the cylinder block as the sleeve is removed.
5. Tighten screw on the puller until the sleeve
comes free from the cylinder block bore.
Remove shims (2), if any are installed.
