DODGE RAM 2001 Service Repair Manual

(2) The upper right corner of the rear face of the
block must be stamped with a X when the block is
refaced to 0.25 mm (0.0098 inch). A second X must be
stamped beside the first when the block is refaced to
0.50 mm (0.0197 inch) - (Fig. 69).
(3) Consult the parts catalog for the proper head
gaskets which must be used with refaced blocks to
ensure proper piston-to-valve clearance.
STANDARD PROCEDURE-CYLINDER BORE -
DE-GLAZE
(1) New piston rings may not seat in glazed cylin-
der bores.
(2) De-glazing gives the bore the correct surface
finish required to seat the rings. The size of the bore
is not changed by proper de-glazing.
(3) Cover the lube holes in the top of the block
with waterproof tape.
(4) A correctly honed surface will have a cross-
hatch appearance with the lines at 15É to 25É angles
(Fig. 70). For the rough hone, use 80 grit honing
stones. To finish hone, use 280 grit honing stones.
(5) Use a drill, a fine grit Flex-hone and a mixture
of equal parts of mineral spirits and SAE 30W engine
oil to de-glaze the bores.
(6)
The crosshatch angle is a function of drill speed
and how fast the hone is moved vertically (Fig. 71).
(7) Vertical strokes MUST be smooth continuous
passes along the full length of the bore (Fig. 71).
(8) Inspect the bore after 10 strokes.
(9) Use a strong solution of hot water and laundry
detergent to clean the bores. Clean the cylinder bores
immediately after de-glazing.
(10) Rinse the bores until the detergent is removed
and blow the block dry with compressed air.

(11) Check the bore cleanliness by wiping with a
white, lint free, lightly oiled cloth. If grit residue is
still present, repeat the cleaning process until all res-
idue is removed. Wash the bores and the complete
block assembly with solvent and dry with compressed
air.
(12) Be sure to remove the tape covering the lube
holes after the cleaning process is complete.
STANDARD PROCEDUREÐCYLINDER BORE
REPAIR
Cylinder bore(s) can be repaired by one of two
methods:
²Method 1:ÐOver boring and using oversize pis-
tons and rings.
²Method 2:ÐBoring and installing a repair sleeve
to return the bore to standard dimensions.
METHOD 1ÐOVERSIZE BORE
Cylinder bore(s) can be repaired by one of two
methods:
Oversize pistons and rings are available in two
sizes - 0.50 mm (0.0197 inch) and 1.00 mm (0.0393
inch).
Any combination of standard, 0.50 mm (0.0197
inch) or 1.00 mm (0.0393 inch) overbore may be used
in the same engine.
If more than 1.00 mm (0.0393 inch) overbore is
needed, a repair sleeve can be installed (refer to
Method 2ÐRepair Sleeve).
Cylinder block bores may be bored twice before use
of a repair sleeve is required (Fig. 72). The first bore
is 0.50 mm (0.0197 inch) oversize. The second bore is
1.00 mm (0.0393 inch) oversize.
After boring to size, use a honing stone to chamfer
the edge of the bore (Fig. 72).

A correctly honed surface will have a crosshatch
appearance with the lines at 15É to 25É angles with
the top of the cylinder block (Fig. 73). For the rough
hone, use 80 grit honing stones. To finish hone, use
280 grit honing stones.
A maximum of 1.2 micrometer (48 microinch) sur-
face finish must be obtained.
After finish honing is complete, immediately clean
the cylinder bores with a strong solution of laundry
detergent and hot water.
After rinsing, blow the block dry.
Check the bore cleanliness by wiping with a white,
lint-free, lightly- oiled cloth. There should be no grit
residue present.
If the block is not to be used right away, coat it
with a rust- preventing compound.
METHOD 2ÐREPAIR SLEEVE
If more than a 1.00 mm (0.03937 inch) diameter
oversize bore is required, the block must be bored
and a repair sleeve installed.

STANDARD PROCEDUREÐCAM BORE REPAIR
The front cam bushing bore can be bored to 59.235
Mm  0.013 mm (2.332 inch  0.0006 inch) oversize.
DO NOT bore the intermediate or rear cam bore to
the front cam bore oversize dimensions. Intermediate
and rear cam bores may be bored to 57.235 mm
 0.013 mm (2.253 inch  0.0006± inch) oversize.
A surface finish of 2.3 micrometers (92 microinch)
must be maintained. Not more than 20% of an area
of any one bore may be 3.2 micrometers (126 micro-
inch).
Camshaft bores can be repaired individually. It is
not necessary to repair undamaged cam bores in
order to repair individually damaged cam bores. The
standard front bushing cannot be used to repair
intermediate or rear bores.
Install all cam bushings flush or below the front
cam bore surface. The oil hole must align to allow a
3.2 mm (0.125 inch) rod to pass through freely (Fig.
78).
