[212 NC] CYLINDER SLEEVE
Description
The cylinder sleeve works with the piston, piston
rings, cylinder head, and cylinder head gasket to
seal combustion pressure. It transfers
combustion heat to engine coolant and guides
piston travel during engine operation. Correct
extension of sleeve flange above top deck and
uniform cylinder block counterbore are essential
for satisfactory sleeve life and head gasket seal.
The cylinder sleeves are a wet-dry design, made
of centrifugal cast iron. A crevice seal is needed
for sealing purposes.

Installation
Refer to Figure 6-12.
1. Thoroughly clean and dry the prepared
cylinder block (6), counterbore ledge (5) and
cylinder sleeves (3). Refer to cylinder block
cleaning procedures in this section.
2. Install the crevice seal (2) into the cylinder
sleeve groove with the pointed face toward
the cylinder block (6) (outward). Lubricate
with ethylene glycol.
3. If the counterbore ledges (5) have been cut,
place the shims (4) on the cylinder block
counterbore ledges. If more than one shim is
necessary, use the fewest number of shims
required to achieve the proper cylinder
sleeve flange height. Always place the
thickest shim on the bottom.
The crevice seal groove (1) must be clean and
free of any oil residue. Under no circumstances
should oil contaminate the crevice seal groove or
crevice seal. Damage to the seal will result.
Applying a Silastic bead is now standard
assembly procedure whenever cylinder sleeves
are installed.
To prevent partial curing and questionable
sealing and bonding, apply Silastic just before
installing the sleeves.
4. Apply approximately a 1/8-inch (3.18 mm)
bead of RTV silicone (Mack Silastic
342SX32, Dow Corning Silastic RTV732, or
General Electric RTV130) around the
cylinder block sleeve seat and completely
around the cylinder wall. Do not use
excessive amounts of RTV.
The cylinder block counterbore ledges and the
cylinder sleeve must be kept clean and free of
any oil residue to ensure that the Silastic bead
seals and bonds properly.
5. Position the cylinder sleeve (3) in the
cylinder bore until it contacts the crevice
seal (2).
6. Placing the palms of the hands on the upper
end of the cylinder sleeve 180 degrees
apart, push downward with a quick, even
pressure. Using a large plastic-faced
hammer, tap the sleeve close to the inside
diameter. Tap alternately from one side to
the other, gradually working around the
entire circumference of the sleeve.
