7. Slide a suitable pin (1) into the holes.
8. Remove camshaft sprocket attaching bolt and
remove timing chain with crankshaft and camshaft
sprockets (2).
9. If tensioner assembly is to be replaced, remove the
tensioner to block bolts and remove tensioner
assembly.
INSTALLATION
1. If tensioner (1) assembly is being replaced, install tensioner and mounting bolts. Torque bolts to 28 Nꞏm (250 in.
lbs.).
2. Retract tensioner (2) if required.
CAUTION: The timing chainmust be installed with
the single plated link aligned with the dot and or
paint marking on the camshaft sprocket. The
crankshaft sprocket is aligned with the dot and or
paint marking on the sprocket between two plated
timing chain links.
CAUTION: The camshaft pin and the slot in the
cam sprocket must be clocked at 12:00. The
crankshaft keyway must be clocked at 2:00. The
crankshaft sprocket must be installed so that the
dots and or paint marking is at 6:00.
3. Place both camshaft sprocket and crankshaft
sprocket on the bench with timing marks on exact
imaginary center line through both camshaft and
crankshaft bores.
4. Place timing chain around both sprockets.
5. Lift sprockets and chain (keep sprockets tight
against the chain in position as shown).
6. Slide both sprockets (2,3) evenly over their respec-
tive shafts and check alignment of timing marks.
7. Install the camshaft bolt. Tighten the bolt to 122 Nꞏm (90 ft. lbs.) torque.

ENGINE - 5.9L DIESEL - SERVICE INFORMATION
DESCRIPTION
DESCRIPTION - 5.9L DIESEL
The cylinder block is constructed of cast iron. The casting is a skirted design which incorporates longitudal ribs for
superior strength and noise reduction. The block incorporates metric straight thread o-ring fittings at lubrication oil
access points. The engine is manufactured with the cylinders being a non-sleeved type cylinder. However, one
approved service method is to bore out the cylinders and add cylinder sleeves to the cylinder block.
The cylinders are numbered front to rear ; 1 to 6. The
firing order is 1–5–3–6–2–4.

DIAGNOSIS AND TESTING - CYLINDER COMPRESSION/LEAKAGE TESTS
CYLINDER COMPRESSION PRESSURE
The results of a cylinder compressionpressure test can be utilized to diagnose several engine malfunctions.
Ensure batteries are completely charged and the engine starter motor is ingood operating condition. Otherwise, the
indicated compression pressures may not be valid for diagnostic purposes.
1. Disconnect the fuel inlet line to the fuel filter housing. Plug the fuel line from the fuel tank.
NOTE: Failure to plug fuel line will result in fuel leak.
2. Remove fuel transfer pump relay from PDC.
3. Start the engine and idle until the engine stalls (runs out of fuel).
4. Remove the cylinder head cover. (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) -
REMOVAL)
5. Remove the cylinder head cover carrier gasket. (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL)
6. Remove the high pressure fuel line between the cylinder head and fuel rail for the cylinder to be tested. Use
tool# 9011 to cap this fuel rail on the cylinder being tested.
7. Remove the fuel connector tube nut and fuel connector tube.
8. Remove the exhaust rocker lever.
9. Use Tool 9010 to remove the injector and copper sealing washer.
10. Install the exhaust rocker lever and torque to 36 Nꞏm (27 ft. lbs.).
11. Cover the remaining rocker levers with clean shop towels to prevent anyoil splatter under the hood.
MoparEngine RTV GEN II is used to seal components exposed to engine oil. This material is a specially designed
black silicone rubber RTV that retains adhesion and sealing properties when exposed to engine oil. Moisture in the
air causes the material to cure. This material is available in three ounce tubes and has a shelf life of one year. After
one year this material will not properly cure. Always inspect the package for the expiration date before use.

AT F R T V
Mopar
ATF RTV is a specifically designed black silicone rubber RTV that retains adhesion and sealing properties
to seal components exposed to automatic transmission fluid, engine coolants, and moisture. This material is avail-
able in three ounce tubes and has a shelf life of one year. After one year thismaterial will not properly cure. Always
inspect the package for the expiration date before use.
MOPAR
GASKET MAKER
Mopar
Gasket Maker is an anaerobic type gasket material. The material cures in the absence of air when
squeezed between two metallic surfaces. It will not cure if left in the uncovered tube. The anaerobic material is for
use between two machined surfaces. Do not use on flexible metal flanges.
MOPAR
GASKET SEALANT
Mopar
Gasket Sealant is a slow drying, permanently soft sealer. This material isrecommended for sealing
threaded fittings and gaskets against leakage of oil and coolant. Can be used on threaded and machined parts
under all temperatures. This material is used on engines with multi-layersteel (MLS) cylinder head gaskets. This
material also will prevent corrosion. Mopar
Gasket Sealant is available in a 13 oz. aerosol can or 4oz./16 oz. can
w/applicator.
FORM-IN-PLACE GASKET AND SEALER APPLICATION
Assembling parts using a form-in-place gasket requires care but it’s easier than using precut gaskets.
Mopar
Gasket Maker material should be applied sparingly 1 mm (0.040 in.) diameter or less of sealant to one
gasket surface. Be certain the material surrounds each mounting hole. Excess material can easily be wiped off.
Components should be torqued in place within 15 minutes. The use of a locating dowel is recommended during
assembly to prevent smearing material off the location.
Mopar
Engine RTV GEN II or ATF RTV gasket material should be applied in a continuous bead approximately 3
mm (0.120 in.) in diameter. All mounting holes must be circled. For corner sealing, a 3.17 or 6.35 mm (1/8 or 1/4 in.)
drop is placed in the center of the gasket contact area. Uncured sealant maybe removed with a shop towel. Com-
ponents should be torqued in place while the sealant is still wet to the touch (within 10 minutes). The usage of a
locating dowel is recommended during assembly to prevent smearing material off the location.
Mopar
Gasket Sealant in an aerosol can should be applied using a thin, even coat sprayed completely over both
surfaces to be joined, and both sides of a gasket. Then proceed with assembly. Material in a can w/applicator can
be brushed on evenly over the sealing surfaces. Material in an aerosol can shouldbeusedonengineswithmulti-
layer steel gaskets.
STANDARD PROCEDURE - REPAIR DAMAGED OR WORN THREADS
CAUTION: Be sure that the tapped holes maintain the original center line.
Damaged or worn threads can be repaired. Essentially, this repair consistsof:
Drilling out worn or damaged threads.
Tapping the hole with a special Heli-Coil Tap, or equivalent.
Installing an insert into the tapped hole to bring the hole back to its original thread size.
STANDARD PROCEDURE—HYDROSTATIC LOCK
CAUTION: DO NOT use the starter motor to rotate the crankshaft. Severe damage could occur.
When an engine is suspected of hydrostatic lock (regardless of what causedthe problem), follow the steps below.
1. Disconnect the negative cable(s) from the battery.
2. Inspect air cleaner, induction system, and intake manifold to ensure system is dry and clear of foreign material.
