CAMSHAFT - LEFT
DESCRIPTION
The camshafts consist of powdered metal steel lobes which are sinter-bonded to a steel tube. A steel post or nose
piece is friction-welded to the steel camshaft tube. Five bearing journals are machined into the camshaft, four on the
steel tube and one on the steel nose piece. Camshaft end play is controlled by two thrust walls that border the nose
piece journal. Engine oil enters the hollow camshafts at the third journaland lubricates every intake lobe rocker
throughadrilledpassageintheintakelobe.
REMOVAL
1. Remove cylinder head cover (1) (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT forcefully
rotate the camshafts or crankshaft independently of each other. Severe valve and/or piston damage can
occur.
CAUTION: When removing the cam sprocket, timing chains or camshaft, Failure to use Special Tool 8350
will result in hydraulic tensioner ratchet over extension, requiring timing chain cover removal to reset the
tensioner ratchet.
2. Set engine to TDC cylinder #1, camshaft sprocket V8 marks at the 12 o’clock position.
3. Mark one link on the secondary timing chain on both sides of the V8 mark on the camshaft sprocket to aid in
installation.

CAUTION: Do not hold or pry on the camshaft target wheel (Located on the right side camshaft sprocket)
for any reason, Severe damage will occur to the target wheel resulting in a vehicle no start condition.
4. Loosen butDO NOTremove the camshaft sprocket retaining bolt. Leave the bolt snug against the sprocket.
NOTE: The timing chain tensioners must be secured prior to removing the camshaft sprockets. Failure to
secure tensioners will allow the tensioners to extend, requiring timing chain cover removal in order to reset
tensioners.
CAUTION: Do not force wedge past the narrowest point between the chain strands. Damage to the tension-
ers may occur.
5. Position Special Tool 8350 (4) timing chain wedge between the timing chain strands, tap the tool to securely
wedge the timing chain against the tensioner arm and guide.
NOTE: When gripping the camshaft, place the pli-
ers on the tube portion of the camshaft only. Do
not grip the lobes or the sprocket areas.
6. Hold the camshaft (3) with adjustable pliers (2)
while removing the camshaft sprocket bolt and
sprocket (1).
7. Using the pliers, gently allow the camshaft to rotate
15° clockwise until the camshaft is in the neutral
position (no valve load).

8. Starting at the outside working inward, loosen the
camshaft bearing cap retaining bolts 1/2 turn at a
time. Repeat until all load is off the bearing caps.
CAUTION: DO NOT STAMP OR STRIKE THE CAM-
SHAFT BEARING CAPS. SEVERE DAMAGE WILL
OCCUR TO THE BEARING CAPS.
NOTE: When the camshaft is removed the rocker
arms may slide downward, mark the rocker arms
before removing camshaft.
9. Remove the camshaft bearing caps and the
camshaft.
INSTALLATION
1. Lubricate camshaft journals with clean engine oil.
NOTE: Position the left side camshaft so that the
camshaft sprocket dowel is near the 1 o’clock
position, This will place the camshaft at the neu-
tral position easing the installation of the camshaft
bearing caps.
2. Position the camshaft into the cylinder head.
3. Install the camshaft bearing caps, hand tighten the
retaining bolts.
4. Working in
1⁄2turn increments, tighten the bearing
cap retaining bolts starting with the middle cap
working outward.
5. Torque the camshaft bearing cap retaining bolts to
11 N ꞏm ( 1 0 0 i n . l b s . ) .

COVER(S) - REMOVAL).
CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT forcefully
rotate the camshafts or crankshaft independently of each other. Severe valve and/or piston damage can
occur.
CAUTION: When removing the cam sprocket, timing chains or camshaft, Failure to use special tool 8350 will
result in hydraulic tensioner ratchet over extension, Requiring timing chain cover removal to re-set the ten-
sioner ratchet.
2. Set engine to TDC cylinder #1, camshaft sprocket V8 marks at the 12 o’clock position.
3. Mark one link on the secondary timing chain on both sides of the V8 mark on the camshaft sprocket to aid in
installation.

6. Remove the camshaft position sensor (1).
NOTE: When gripping the camshaft, place the pli-
ers (1) on the tube portion of the camshaft only.
Do not grip the lobes or the sprocket areas.
7. Hold the camshaft with adjustable pliers (1) while
removing the camshaft sprocket bolt (2)and
sprocket (3).
8. Using the pliers (1), gently allow the camshaft to
rotate 45° counter-clockwise until the camshaft is in
the neutral position (no valve load).

9. Starting at the outside working inward, loosen the
camshaft bearing cap retaining bolts 1/2 turn at a
time. Repeat until all load is off the bearing caps.
CAUTION: DO NOT STAMP OR STRIKE THE CAM-
SHAFT BEARING CAPS. SEVERE DAMAGE WILL
OCCUR TO THE BEARING CAPS.
NOTE: When the camshaft is removed the rocker
arms may slide downward, mark the rocker arms
before removing camshaft.
10. Remove the camshaft bearing caps and the
camshaft.
INSTALLATION
1. Lubricate camshaft journals with clean engine oil.
NOTE: Position the right side camshaft so that the
camshaft sprocket dowel is near the 10 o’clock
position, This will place the camshaft at the neu-
tral position easing the installation of the camshaft
bearing caps.
2. Position the camshaft into the cylinder head.
3. Install the camshaft bearing caps, hand tighten the
retaining bolts.
4. Working in 1/2 turn increments, tighten the bearing
cap retaining bolts starting with the middle cap
working outward.
5. Torque the camshaft bearing cap retaining bolts to
11 N ꞏm ( 1 0 0 i n . l b s . ) .

6. lubricate the camshaft journal with clean engine oil
then Position the camshaft (with the sprocket dowel
on the left camshaft at 11 o’clock and the right
camshaft at 12 o’clock), then position the camshaft
bearing caps.
7. Install the camshaft bearing cap retaining bolts.
Tighten the bolts 9–13 Nꞏm (100 in. lbs.) in
1⁄2turn
increments in the sequence shown.
8. Position the hydraulic lash adjusters and rocker
arms.

FILTER - ENGINE OIL
REMOVAL
All engines are equipped with a high quality full-flow,
disposable type oil filter. DaimlerChrysler Corporation
recommends a Mopar
or equivalent oil filter be used.
1. Position a drain pan under the oil filter.
2. Using a suitable oil filter wrench loosen filter.
3. Rotate the oil filter counterclockwise to remove it
from the cylinder block oil filter boss.
4. When filter separates from cylinder block oil filter
boss, tip gasket end upward to minimize oil spill.
Remove filter from vehicle.
NOTE: Make sure filter gasket was removed with
filter.
5. With a wiping cloth, clean the gasket sealing sur-
face of oil and grime.
INSTALLATION
1. Lightly lubricate oil filter gasket (2) with engine oil.
2. Thread filter (3) onto adapter nipple. When gasket
makes contact with sealing surface, hand tighten
filter one full turn, do not over tighten.
3. Add oil, verify crankcase oil level and start engine.
Inspect for oil leaks.
