Downloaded from www.Manualslib.com manuals search engine (4) Hold puller screw and tighten puller nut until
bushing is removed.
INSTALLATION
(1) Slide new bushing over burnishing end of Dis-
tributor Drive Shaft Bushing Driver/Burnisher Tool
C-3053. Insert the tool and bushing into the bore.
(2) Drive bushing and tool into position, using a
hammer (Fig. 64).
(3) As the burnisher is pulled through the bushing,
the bushing is expanded tight in the block and bur-
nished to correct size (Fig. 65).DO NOT ream this
bushing.
CAUTION: This procedure MUST be followed when
installing a new bushing or seizure to shaft may
occur.
(4) Install the intake manifold.
DISTRIBUTOR INSTALLATION
NOTE: Before installing the distributor, the oil
pump drive shaft must be aligned to number one
cylinder.(1) Rotate crankshaft until No.1 cylinder is at top
dead center on the firing stroke.
(2) When in this position, the timing mark of
vibration damper should be under ª0º on the timing
indicator.
(3) Install the shaft so that after the gear spirals
into place, it will index with the oil pump shaft. The
slot on top of oil pump shaft should be aligned
towards the left front intake manifold attaching bolt
hole (Fig. 66).
(4) Install distributor, refer to Group 8D, Ignition
Systems for the proper procedure.
After the distributor has been installed, its rota-
tional position must be set using theSET SYNC
mode of the DRB scan tool. Refer to Checking Dis-
tributor Position following the Distributor Installa-
tion section in Group 8D, Ignition system.
Do not attempt to adjust ignition timing by
rotating the distributor. It has no effect on igni-
tion timing. Adjusting distributor position will
effect fuel synchronization only.

INSPECTION OF JOURNALS
The crankshaft connecting rod and main journals
should be checked for excessive wear, taper and scor-
ing. The maximum taper or out-of-round on any
crankshaft journal is 0.025 mm (0.001 inch).
Journal grinding should not exceed 0.305 mm
(0.012 inch) under the standard journal diameter. DO
NOT grind thrust faces of No.3 main bearing. DO
NOT nick crank pin or bearing fillets. After grinding,
remove rough edges from crankshaft oil holes and
clean out all oil passages.
CAUTION: After any journal grind, it is important
that the final paper or cloth polish be in the same
direction as the engine rotates.
CLEANING
Clean Loctite 518 residue and sealant from the cyl-
inder block and rear cap mating surface. Do this
before applying the Loctite drop and the installation
of rear cap.

equivalent, on each side of the rear main bearing cap
(Fig. 72). DO NOT over apply sealant or allow the
sealant to contact the rubber seal. Assemble bearing
cap to cylinder block immediately after sealant appli-
cation.
(7) To align the bearing cap, use cap slot, align-
ment dowel and cap bolts. DO NOT remove excess
material after assembly. DO NOT strike rear cap
more than 2 times for proper engagement.
(8) Clean and oil all cap bolts. Install all main
bearing caps. Install all cap bolts and alternately

or equivalent, at bearing cap to block joint to provide
cap to block and oil pan sealing (Fig. 73). Apply
enough sealant until a small amount is squeezed out.Withdraw nozzle and wipe excess sealant off the oil
pan seal groove.
(10) Install new front crankshaft oil seal.
(11) Immediately install the oil pan.

(3) If front seal is suspected of leaking, check front
oil seal alignment to crankshaft. The seal installa-
tion/alignment tool 6635, should fit with minimum
interference. If tool does not fit, the cover must be
removed and installed properly.
(4) Place a suitable tool behind the lips of the oil
seal to pry the oil seal outward. Be careful not to
damage the crankshaft seal bore of cover.

CLEANING AND INSPECTION
CYLINDER HEAD COVER
CLEANING
Clean cylinder head cover gasket surface.
Clean head rail, if necessary.
INSPECTION
Inspect cover for distortion and straighten, if nec-
essary.
Check the gasket for use in head cover installation.
If damaged, use a new gasket.
CYLINDER HEAD ASSEMBLY
CLEANING
Clean all surfaces of cylinder block and cylinder
heads.
Clean cylinder block front and rear gasket surfaces
using a suitable solvent.
INSPECTION
Inspect all surfaces with a straightedge if there is
any reason to suspect leakage. If out-of-flatness
exceeds 0.00075 mm/mm (0.00075 inch/inch) times
the span length in inches in any direction, either
replace head or lightly machine the head surface.
FOR EXAMPLE:A 305 mm (12 inch) span is
0.102 mm (0.004 inch) out-of-flat. The allowable out-
of-flat is 305 X 0.00075 (12 X 0.00075) equals 0.23
mm (0.009 inch). This amount of out-of-flat is accept-
able.
The cylinder head surface finish should be
1.78-3.00 microns (70-125 microinches).
PISTON AND CONNECTING ROD ASSEMBLY
INSPECTION
Check the crankshaft connecting rod journal for
excessive wear, taper and scoring.
Check the cylinder block bore for out-of-round,
taper, scoring and scuffing.Check the pistons for taper and elliptical shape
before they are fitted into the cylinder bore (Fig. 83).
OIL PAN
CLEANING
Clean the block and pan gasket surfaces.
Trim or remove excess sealant film in the rear
main cap oil pan gasket groove.DO NOT remove
the sealant inside the rear main cap slots.
If present, trim excess sealant from inside the
engine.
Clean oil pan in solvent and wipe dry with a clean
cloth.
Clean oil screen and pipe thoroughly in clean sol-
vent. Inspect condition of screen.
INSPECTION
Inspect oil drain plug and plug hole for stripped or
damaged threads. Repair as necessary.
Inspect oil pan mounting flange for bends or distor-
tion. Straighten flange, if necessary.
OIL PUMP
INSPECTION
Mating surface of the oil pump cover should be
smooth. Replace pump assembly if cover is scratched
or grooved.
Lay a straightedge across the pump cover surface
(Fig. 84). If a 0.038 mm (0.0015 inch) feeler gauge
can be inserted between cover and straightedge,
pump assembly should be replaced.
