REPAIR INSTRUCTIONS
Cylinder Sleeve Installation
[212 NC]
GENERAL INFORMATION
The cylinder sleeves are a wet-dry design made
of centrifugally cast alloyed iron. Working with the
pistons, piston rings, cylinder heads and cylinder
head gaskets, the sleeves provide a seal against
combustion pressure. The sleeves also transfer
combustion heat to the engine coolant and guide
piston travel. Correct extension of the sleeve
flange above the top deck and uniform cylinder
block counterbore are essential for satisfactory
sleeve service life and head gasket seal.
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.

INSTALLATION PROCEDURE
Refer to Figure 145.
1. Thoroughly clean and dry the prepared
cylinder block (4), counterbore ledge (3) and
cylinder sleeves (1). Refer to the cylinder
block cleaning and inspection procedures in
this section.
2. If the counterbore ledge (3) has been cut,
place the shims (2) on the cylinder block
counterbore ledge. Use the fewest number
of shims required to achieve the proper
cylinder sleeve flange height. Always place
the thickest shim on the bottom.
If shims are used, apply RTV silicone on top of
the shims only. If RTV is applied under the shims,
the shims may be displaced when the sleeve is
installed
3. Apply approximately a 0.120–0.160-inch
(3.048–4.064-mm) bead of RTV silicone
(MACK Silastic
®
342SX32, Dow Corning
Silastic
®
RTV732 or General Electric
RTV130) on the cylinder block sleeve seat
and completely around the cylinder wall as
shown in Figure 145. Do not use excessive
amounts of RTV. Do not apply more than a
0.160-inch bead.
