CRANKSHAFT
DESCRIPTION
The crankshaft (Fig. 22) is of a cast nodular steel
splayed type design, with five main bearing journal-
s.The crankshaft is located at the bottom of the
engine block and is held in place with five main bear-
ing caps. The number 3 counterweight is the location
for journal size identification.
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder bores to the flywheel or
flexplate.
REMOVAL
NOTE: This procedure can be done in vehicle. How-
ever the transmission must be removed first.
(1) If crankshaft is to be removed while engine is
in vehicle remove the transmission. Refer to Group
21, for correct procedure.
(2) Remove the oil pan (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - REMOVAL).
(3) Remove the oil pump from the rear main bear-
ing cap (Refer to 9 - ENGINE/LUBRICATION/OIL

(5) Remove the timing chain cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL).
(6) Identify rod bearing caps before removal.
Remove rod bearing caps with bearings.CAUTION: Support crankshaft before removing
main bearing caps. failure to do so will allow the
crankshaft to fall damaging the crankshaft.
(7) Using a suitable jack, support the crankshaft.
(8) Identify main bearing caps before removal.
Remove main bearing caps and bearings one at a
time.
(9) Lower the crankshaft out of the block.
(10) Remove and discard the crankshaft rear oil
seals.

oil.
(3) Install the new upper rear bearing oil seal with
the white paint facing towards the rear of the engine.
(4) Position the crankshaft into the cylinder block.
(5) Lightly oil the new lower seal lips with engine
oil.
(6) Install the new lower rear bearing oil seal into
the bearing cap with the white paint facing towards
the rear of the engine.

Maker, or equivalent, on each side of the rear main
bearing cap (Fig. 23). DO NOT over apply sealant or
allow the sealant to contact the rubber seal. Assem-
ble bearing cap to cylinder block immediately after
sealant application.
(8) To align the bearing cap, use cap slot, align-
ment dowel and cap bolts. DO NOT remove excess

HYDRAULIC LIFTERS
DIAGNOSIS AND TESTINGÐHYDRAULIC
TAPPETS
Before disassembling any part of the engine to cor-
rect tappet noise, check the oil pressure. If vehicle
has no oil pressure gauge, install a reliable gauge at
the pressure sending-unit. The pressure should be
between 207-552 kPa (30-80 psi) at 3,000 RPM.
Check the oil level after the engine reaches normal
operating temperature. Allow 5 minutes to stabilize
oil level, check dipstick. The oil level in the pan
should never be above the FULL mark or below the
ADD OIL mark on dipstick. Either of these two con-
ditions could be responsible for noisy tappets.
OIL LEVEL
HIGH
If oil level is above the FULL mark, it is possible
for the connecting rods to dip into the oil. With the
engine running, this condition could create foam in
the oil pan. Foam in oil pan would be fed to the
hydraulic tappets by the oil pump causing them to
lose length and allow valves to seat noisily.
LOW
Low oil level may allow oil pump to take in air.
When air is fed to the tappets, they lose length,
which allows valves to seat noisily. Any leaks on
intake side of oil pump through which air can be
drawn will create the same tappet action. Check the
lubrication system from the intake strainer to the
pump cover, including the relief valve retainer cap.
When tappet noise is due to aeration, it may be
intermittent or constant, and usually more than one
tappet will be noisy. When oil level and leaks have
been corrected, operate the engine at fast idle. Run
engine for a sufficient time to allow all of the air
inside the tappets to be bled out.
TAPPET NOISE DIAGNOSIS
(1) To determine source of tappet noise, operate
engine at idle with cylinder head covers removed.
(2) Feel each valve spring or rocker arm to detect
noisy tappet. The noisy tappet will cause the affected
spring and/or rocker arm to vibrate or feel rough in
operation.
