Downloaded from www.Manualslib.com manuals search engine (7) Place timing chain around both sprockets.
(8) Turn crankshaft and camshaft to line up with
keyway location in crankshaft sprocket and in cam-
shaft sprocket.
(9) Lift sprockets and chain (keep sprockets tight
against the chain in position as described).
(10) Slide both sprockets evenly over their respec-
tive shafts and use a straightedge to check alignment
of timing marks (Fig. 25).
(11) Install the camshaft bolt. Tighten the bolt to
47 N´m (35 ft. lbs.) torque.
(12) Check camshaft end play. The end play should
be 0.051-0.152 mm (0.002-0.006 inch) with a new
thrust plate and up to 0.254 mm (0.010 inch) with a
used thrust plate. If not within these limits install a
new thrust plate.
PISTONSÐFITTING
Piston and cylinder wall must be clean and dry.
Specified clearance between the piston and the cylin-
der wall is 0.013-0.038 mm (0.0005-0.0015 inch) at
21ÉC (70ÉF).
Piston diameter should be measured at the top of
skirt, 90É to piston pin axis. Cylinder bores should be
measured halfway down the cylinder bore and trans-
verse to the engine crankshaft center line.
Pistons and cylinder bores should be measured at
normal room temperature, 21ÉC (70ÉF).
Check the pistons for taper and elliptical shape
before they are fitted into the cylinder bore (Fig. 26).
PISTON RINGSÐFITTING
(1) Measurement of end gaps:
(a) Measure piston ring gap 2 inches from bot-
tom of cylinder bore. An inverted piston can be
used to push the rings down to ensure positioning
rings squarely in the cylinder bore before measur-
ing.
(b) Insert feeler gauge in the gap. The top com-
pression ring gap should be between 0.254-0.508
mm (0.010-0.020 inch). The second compressionring gap should be between 0.508-0.762 mm (0.020-
0.030 inch). The oil ring gap should be 0.254-1.270
mm (0.010-0.050 inch).
(c) Rings with insufficient end gap may be prop-
erly filed to the correct dimension. Rings with
excess gaps should not be used.
(2) Install rings and confirm ring side clearance:
(a) Install oil rings being careful not to nick or
scratch the piston. Install the oil control rings
according to instructions in the package. It is not
necessary to use a tool to install the upper and
lower rails. Insert oil rail spacer first, then side
rails.
(b) Install the second compression rings using
Installation Tool C-4184. The compression rings
must be installed with the identification mark face
up (toward top of piston) and chamfer facing down.
An identification mark on the ring is a drill point,
a stamped letter ªOº, an oval depression or the
word TOP (Fig. 27) (Fig. 29).
(c) Using a ring installer, install the top com-
pression ring with the chamfer facing up (Fig. 28)
(Fig. 29). An identification mark on the ring is a
drill point, a stamped letter ªOº, an oval depression
or the word TOP facing up.
(d) Measure side clearance between piston ring
and ring land. Clearance should be 0.074-0.097 mm
(0.0029-0.0038 inch) for the compression rings. The
steel rail oil ring should be free in groove, but
should not exceed 0.246 mm (0.0097 inch) side
clearance.
(e) Pistons with insufficient or excessive side
clearance should be replaced.

equipped, the speed control and transmission kick-
down cables.
(10) Remove the distributor cap and wires.
(11) Disconnect the coil wires.
(12) Disconnect the coolant temperature sending
unit wire.
(13) Disconnect the heater hoses and bypass hose.
(14) Remove the closed crankcase ventilation and
evaporation control systems.
(15) Remove intake manifold bolts.
(16) Lift the intake manifold and throttle body out
of the engine compartment as an assembly.
(17) Remove and discard the flange side gaskets
and the front and rear cross-over gaskets.
(18) Remove the throttle body bolts and lift the
throttle body off the intake manifold (Fig. 40). Dis-
card the throttle body gasket.
INSTALLATION
(1) If the plenum pan was removed, position pan
gasket and pan.
(2) Install plenum pan retaining bolts. (Fig. 41).
(3) Tighten plenum pan mounting bolts as follows:
²Step 1. Tighten bolts to 5.4 N´m (24 in. lbs.)
²Step 2. Tighten bolts to 9.5 N´m (84 in. lbs.)
²Step 3. Check all bolts are at 9.5 N´m (84 in.
lbs.)
(4) Using a new gasket, install the throttle body
onto the intake manifold. Tighten the bolts to 23 N´m
(200 in. lbs.) torque.
(5) Apply a bead of Mopar Silicone Rubber Adhe-
sive Sealant, or equivalent, to the four corner joints.
The sealant bead height should be slightly higher
than the cross-over gaskets, approximately 5 mm (0.2
in). An excessive amount of sealant is not required to
ensure a leak proof seal, and an excessive amount of
sealant may reduce the effectiveness of the flange
gasket.
(6) Install the front and rear cross-over gaskets
onto the engine (Fig. 42).
(7) Install the flange gaskets. Ensure that the ver-
tical port alignment tab is resting on the deck face of
the block. Also the horizontal alignment tabs must be
in position with the mating cylinder head gasket tabs
(Fig. 43). The words MANIFOLD SIDE should be vis-
ible on the center of each flange gasket.
(8) Carefully lower intake manifold into position
on the cylinder block and cylinder heads. long studs
at the front and rear of the manifold will help to
align the intake manifold. After intake manifold is in

REMOVAL AND INSTALLATION (Continued)

Downloaded from www.Manualslib.com manuals search engine (4) Before removing valves, remove any burrs from
valve stem lock grooves to prevent damage to the
valve guides. Identify valves to ensure installation in
original location.
INSTALLATION
(1) Coat valve stems with lubrication oil and insert
them in cylinder head.
(2) If valves or seats are reground, check valve
stem height. If valve is too long, replace cylinder
head.
(3) Install new seals on all valve guides. Install
valve springs and valve retainers.
(4) Compress valve springs with Valve Spring
Compressor Tool MD-998772A, install locks and
release tool. If valves and/or seats are ground, mea-
sure the installed height of springs. Make sure the
measurement is taken from bottom of spring seat in
cylinder head to the bottom surface of spring
retainer. If spacers are installed, measure from the
top of spacer. If height is greater than 42.86 mm
(1-11/16 inches), install a 1.587 mm (1/16 inch)
spacer in head counterbore. This should bring spring
height back to normal 41.27 to 42.86 mm (1-5/8 to
1-11/16 inch).
HYDRAULIC TAPPETS
REMOVAL
(1) Remove the air cleaner assembly and air inlet
hose.

and push rods. Identify push rods to ensure installa-
tion in original location.
(3) Remove intake manifold, yoke retainer and
aligning yokes.
(4) Slide Hydraulic Tappet Remover/Installer Tool
C-4129-A through opening in cylinder head and seat
tool firmly in the head of tappet.
(5) Pull tappet out of bore with a twisting motion.
If all tappets are to be removed, identify tappets to
ensure installation in original location.
INSTALLATION
(1) If the tappet or bore in cylinder block is scored,
scuffed, or shows signs of sticking, ream the bore to
next oversize. Replace with oversize tappet.
(2) Lubricate tappets.
(3) Install tappets and push rods in their original
positions. Ensure that the oil feed hole in the side of
the tappet body faces up (away from the crankshaft).
(4) Install aligning yokes with ARROW toward
camshaft.
(5) Install yoke retainer. Tighten the bolts to 23
N´m (200 in. lbs.) torque. Install intake manifold.
(6) Install push rods in original positions.(7) Install rocker arm.
(8) Install cylinder head cover.
(9) Install air cleaner assembly and air inlet hose.
(10) Start and operate engine. Warm up to normal
operating temperature.
CAUTION: To prevent damage to valve mechanism,
engine must not be run above fast idle until all
hydraulic tappets have filled with oil and have
become quiet.
