INTAKE/EXHAUST VALVES &
SEATS
DESCRIPTION
The valves are made of heat resistant steel, and
have chrome plated stems to prevent scuffing. Theintake and exhaust valves are both similar in head
diameter and overall length, but they have unique
face angles which makes them non-interchangeable.
The valves are distinguished by unique dimples on
the exhaust valve head (Fig. 35) .
The exhaust valve springs are made from high
strength, chrome silicon steel. The exhaust valve
springs are also exhaust brake compatible.

(5) Before removing the piston(s) from the bore(s):
(a) Remove any carbon ridge formations or
deposits at the top of the bore with a dull scraper
or soft wire brush.
(b) If cylinder bore wear ridges are found, use a
ridge reamer to cut the ridge from the bore. DO
NOT remove more metal than necessary to remove
the ridge.
NOTE: If cylinders have ridges, the cylinders are
oversize and will more than likely need boring.
(6) Using a hammer and steel stamp, identify the
front of the piston by stamping the cylinder number
in each piston to be removed at the top of the piston
toward the front of the engine. DO NOT stamp in the
outside 5 mm (.197 in.) of the piston diameter.
(7) Mark the connecting rod and cap with the cor-
responding cylinder numbers.
(8) Remove the connecting rod bolts and rod caps.
Use care so the cylinder bores and connecting rods
are not damaged.
(9) Use a hammer handle or similar object to push
the piston and connecting rod through the cylinder
bore.
(10) Store the piston/rod assemblies in a rack.
(11) If a piston must be replaced, replace with the
same part number (grading) that was removed.
CLEANING
CAUTION: DO NOT use bead blast to clean the pis-
tons. DO NOT clean the pistons and rods in an acid
tank.
Clean the pistons and pins in a suitable solvent,
rinse in hot water and blow dry with compressed air.
Soaking the pistons over night will loosen most of the
carbon build up. De-carbon the ring grooves with a
broken piston ring and again clean the pistons in sol-vent. Rinse in hot water and blow dry with com-
pressed air.
INSPECTION
INSPECTION
Inspect the pistons for damage and excessive wear.
Check top of the piston, ring grooves, skirt and pin
bore. Measure the piston skirt diameter (Fig. 128). If
the piston is out of limits, replace the piston.
The upper groove only needs to be inspected for
damage. Use a new piston ring to measure the clear-
ance in the intermediate ring groove (Fig. 129). If the
clearance of the intermediate ring exceeds 0.095 mm
(0.0038 inch), replace the piston.
Use a new oil ring to measure the clearance in the
oil groove (Fig. 129). If the clearance exceeds 0.085
mm (0.0034 inch), replace the piston.
Measure the pin bore (Fig. 130). The maximum
diameter is 40.012 mm (1.5753 inch). If the bore is
over limits, replace the piston.
Inspect the piston pin for nicks, gouges and exces-
sive wear. Measure the pin diameter (Fig. 131). The
minimum diameter is 39.990 mm (1.5744 inch). If the
diameter is out of limits, replace the pin.
Connecting Rods
CLEANING
Clean the connecting rods in a suitable solvent,
rinse in hot water and blow dry with compressed air.
INSPECTION
Inspect the connecting rod for damage and wear.
The I-Beam section of the connecting rod cannot have
dents or other damage. Damage to this part can
cause stress risers which will progress to breakage.

If out of limits, replace the connecting rod.
INSTALLATION
(1) Lubricate the cylinder bores with clean engine
oil.
(2) Generously lubricate the rings and piston
skirts with clean engine oil.
(3) Compress the rings using a piston ring com-
pressor tool (Fig. 133). If using a strap-type ring com-
pressor, make sure the inside end of the strap does
not hook on a ring gap and break the ring.
(4) Bar the crankshaft so the rod journal for the
piston to be installed is at BDC (Bottom Dead Cen-
ter) - (Fig. 134).
(5) Be sure the mark you made on the piston and
the numbers on the rod and cap are oriented as illus-
trated.
(6) Position the piston and rod assembly into the
cylinder bore with the mark you made on the piston
towards the front of the cylinder block. In this posi-
tion the numbers on the connecting rod should be
facing the oil cooler side of the engine, and the rod

install the piston and connecting rod so the cylinder
bore is not damaged.
(7) Push the piston into the bore until the top of
the piston is approximately 50 mm (2 inch) below the
top of the block. Carefully pull the connecting rod
onto the crankshaft journal.
(8) Use clean engine oil to lubricate the threads
and under the heads of the connecting rod bolts.
(9) The number stamped on the rod cap at the
parting line must match and be installed towards the
oil cooler side of the engine (Fig. 135).
(10) Install the rod cap and bolts to the connecting
rod. Tighten the connecting rod and bolt evenly in 3
steps.
²Tighten the bolts to 35 N´m (26 ft. lbs.) torque.
²Tighten the bolts to 70 N´m (51 ft. lbs.) torque.
²Tighten the bolts to 100 N´m (73 ft. lbs.) torque.
(11) The crankshaft must rotate freely. Check for
freedom of rotation as the caps are installed. If the
crankshaft does not rotate freely, check the installa-
tion of the rod bearing and the bearing size.
(12) Measure the side clearance between the con-
necting rod and the crankshaft (Fig. 136). DO NOT
measure the clearance between the cap and crank-
shaft.(13) Install the suction tube and oil pan (Refer to 9
- ENGINE/LUBRICATION/OIL PAN - INSTALLA-
TION).
