BLOCK-ENGINE
DESCRIPTION
The cylinder block is made of a sand-cast aluminum alloy. The cylinder block has interference-fit cast iron cylinder
liners. The cylinder liners are thermally installed during block manufacturing; they are not serviceable items.
Six iron main bearing caps use four bolts per cap; two vertical and two horizontal. A crankshaft oil scraper is
attached to the main bearing caps via extended main bearing cap bolts and nuts.
STANDARD PROCEDURE - CYLINDER BORE HONING
Before honing, stuff plenty of clean shop towels under
the bores and over the crankshaft to keep abrasive
materials from entering the crankshaft area.
1. Used carefully, the Cylinder Bore Sizing Hone
C-823, equipped with 220 grit stones, is the best
tool for this job. In addition to deglazing, it will
reduce taper and out-of-round, as well as removing
light scuffing, scoring and scratches. Usually, a few
strokes will clean up a bore and maintain the
required limits.
CAUTION: DO NOT use rigid type hones to remove
cylinder wall glaze.
2. Deglazing of the cylinder walls may be done if the
cylinder bore is straight and round. Use a cylinder
surfacing hone, Honing Tool C-3501, equipped with
280 grit stones (C-3501-3810). about 20-60
strokes, depending on the bore condition, will be
sufficient to provide a satisfactory surface. Using
honing oil C-3501-3880, or a light honing oil, avail-
able from major oil distributors.
CAUTION: DO NOT use engine or transmission oil, mineral spirits, or kerosene.
3. Honing should be done by moving the hone up and down fast enough to get a crosshatch pattern. The hone
marks should INTERSECT at 50° to 60° for proper seating of rings.
4. A controlled hone motor speed between 200 and 300 RPM is necessary to obtain the proper crosshatch angle.
The number of up and down strokes per minute can be regulated to get the desired 50° to 60° angle. Faster up
and down strokes increase the crosshatch angle.
5. After honing, it is necessary that the block be cleaned to remove all traces of abrasive. Use a brush to wash
parts with a solution of hot water and detergent. Dry parts thoroughly. Usea clean, white, lint-free cloth to check
that the bore is clean. Oil the bores after cleaning to prevent rusting.
CLEANING
CAUTION: Remove all gasket material from cylinder block using a plastic gasket scraper and MoparBrake
Parts Cleaner or the equivalent, this will prevent damage to the cylinder block.
1. When cleaning the cylinder block, remove the oil gallery plugs at the front and rear of the block.
2. Spray compressed air into all oil gallery passages to ensure they are clear of blockage.
3. Use a wooden or plastic scraper and MOPAR
Brake Parts Cleaner or the equivalent to remove the old gasket.
4. Clean the oil passages in the crankshaft with a brush.

INSPECTION
The cylinder walls should be checked for out-of-round
and taper with Special Tool C-119 (1). If the cylinder
walls are badly scuffed or scored, the cylinder bore
can be machined oversize. Oversize piston and rings
are available.
Measure the cylinder bore at three levels in directions
A and B. Top measurement should be 12 mm (0.50
in.) down and bottom measurement should be 12 mm
(0.50 in.) up from bottom of bore. (Refer to 9 -
ENGINE - SPECIFICATIONS) for cylinder bore and
piston specifications.

HYDRAULIC TAPPETS
DESCRIPTION
The roller type design hydraulic tappets (3) are posi-
tioned in the cylinder block. Roller tappet alignment is
maintained by machined flats on tappet body being fit-
ted in pairs into ten aligning yokes (2).
REMOVAL
1.Removecylinderhead(s)(Referto9-ENGINE/
CYLINDER HEAD - REMOVAL).
NOTE: If tappets (3) are to be reused, identify tap-
pet location to ensure installation in original loca-
tion.

3. Remove tappets (3) from bores.
CAUTION: Do not disassemble tappets.

INSTALLATION
1. Lubricate tappets.
2. Install tappets in their original positions with oil
holes (1) facing up.

ing yoke assemblies. Apply Mopar
Lock & Seal
