(1) Install any of the original connecting rod and
piston assemblies into the No.1 cylinder. DO NOT
install the piston rings.
(2) Install the upper bearing shell in the connect-
ing rod with the tang of the bearing in the slot of the
connecting rod. The connecting rod bearing shell
must be installed in the original connecting rod and
cap. Use clean lubricating oil to coat the inside diam-
eter of the connecting rod bearing shell.
(3) Install the bearing shell in the connecting rod
cap with the tang of the bearing in the slot to the
cap. Use clean lubricating oil to coat the inside diam-
eter of the bearing shell.
(4) The four digit number stamped on the connect-
ing rod and cap at the parting line must match andbe installed on the oil cooler side of the engine.
Install the connecting rod cap and cap screws.
Tighten the cap screws to 35 N´m (26 ft. lbs.) torque.
(5) Use a fine grit stone to remove any burrs from
the cylinder block head deck. Zero the dial indicator
to the cylinder block head deck.
(6) Move the dial indicator directly over the piston
pin to eliminate any side-to-side movement.
(7) Rotate the crankshaft to top dead center
(TDC). Rotate the crankshaft clockwise and counter-
clockwise to find the highest dial indicator reading.
Record the reading.
(8) Remove the piston and connecting rod assem-
bly from the No.1 cylinder and install the assembly
into the No.2 cylinder. Repeat the procedure for every
cylinder using the same piston and connecting rod
assembly.
(9) Determine the grade of the piston being used
by referring to the Piston Protrusion Chart below.
Four digits on top of the piston can be cross refer-
enced to a DaimlerChrysler part number for replace-
ment (Fig. 126). If the number on the piston cannot
be seen, measure from the top of the piston to the top
of the piston pin to see what grade piston is used
(Fig. 127).
NOTE: NEVER INTERMIX PISTONS FROM ONE
ENGINE APPLICATION TO ANOTHER ENGINE
APPLICATION. SEVER DRIVEABILITY CONCERNS
MAY RESULT.

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).
(14) Install the cylinder head onto the engine
(Refer to 9 - ENGINE/CYLINDER HEAD - INSTAL-
LATION).
(15) Install a new filter and fill the crankcase with
new engine oil.
(16) Connect the battery negative cables and start
engine.
PISTON RINGS
STANDARD PROCEDURE - PISTON RING
FITTING
(1) Determine the piston diameter and obtain the
appropriate ring set. The piston rings can be identi-
fied as shown in (Fig. 137).

LUBRICATION
DESCRIPTION
NOTE: Refer to (Fig. 148) and (Fig. 149) for circuit
illustrations.
A gear driven gerotor type oil pump is mounted
behind the front gear cover in the lower right portion
on the engine.
OPERATION
A gerotor style oil pump draws oil from the crank-
case through the suction tube and delivers it through
the block where it enters the oil cooler cover and
pressure regulator valve. When oil pressure exceeds
449 kPa (65 PSI), the valve opens exposing the dump
port, which routes excess oil back to the oil sump.
At the same time, oil is directed to a cast in pas-
sage in the oil cooler cover, leading to the oil cooler
element. As the oil travels through the element
plates, it is cooled by engine coolant traveling past
the outside of the plates. It is then routed to the oil
filter head and through a full flow oil filter. If a
plugged filter is encountered, the filter by-pass valve
opens, allowing unfiltered oil to lubricate the engine.
This condition can be avoided by frequent oil and fil-
ter changes, per the maintenance schedules found in
the owners manual. The by-pass valve is calibrated
to open when it sees a pressure drop of more than
344 kPa (50 psi) across the oil filter.
The oil filter head then divides the oil between the
engine and the turbocharger. The turbocharger
receives filtered, cooled and pressurized oil through a
supply line from the filter head. The oil lubricates
the turbocharger and returns to the pan by way of a
drain tube connecting the bottom of the turbocharger
to a pressed in tube in the cylinder block.
Oil is then carried across the block to an angle
drilling which intersects the main oil rifle. The main

DIAGNOSIS AND TESTINGÐENGINE OIL
PRESSURE
(1) Remove the engine oil pressure sensor and
install Oil Pressure Line and Gauge Tool C-3292 with
a suitable adapter.
(2) Start engine and warm to operating tempera-
ture.
(3) Record engine oil pressure and compare with
engine oil pressure chart.
CAUTION: If engine oil pressure is zero at idle, DO
NOT RUN THE ENGINE.
Engine Oil Pressure (MIN)
At Idle 103.4 kPa (15 psi)
At 2000 rpm 310.2 kPa (45 psi)
If minimum engine oil pressure is below these
ranges, (Refer to 9 - ENGINE - DIAGNOSIS AND
TESTING).
(4) Remove oil pressure gauge and install the oil
pressure sensor. Tighten the sensor to 16 N´m (144
in. lbs.) torque.
OIL
STANDARD PROCEDURE
STANDARD PROCEDURE - ENGINE OIL LEVEL
CAUTION: Do not overfill crankcase with engine oil,
oil foaming and oil pressure loss can result.
To ensure proper lubrication of an engine, the
engine oil must be maintained at an acceptable level.
The acceptable oil level is in the SAFE RANGE on
the engine oil dipstick (Fig. 150).
Unless the engine has exhibited loss of oil pres-
sure, run the engine for about five minutes before
checking oil level. Checking engine oil level of a cold
engine is not accurate.
(1) Position vehicle on level surface.(2) With engine OFF, allow approximately ten min-
utes for oil to settle to bottom of crankcase, remove
engine oil dipstick.
(3) Wipe dipstick clean.
(4) Replace dipstick and verify it is seated in the
tube.
(5) Remove dipstick, with handle held above the
tip, take oil level reading.
(6) Add oil only if level is below the SAFE RANGE
area on the dipstick.
(7) Replace dipstick
STANDARD PROCEDURE - ENGINE OIL
SERVICE
WARNING: HOT OIL CAN CAUSE PERSONAL
INJURY.
NOTE: Change engine oil and filter at intervals
specified in the owner's manual.
(1) Operate the engine until the water tempera-
ture reaches 60ÉC (140ÉF). Shut the engine off.
(2) Use a container that can hold at least 14 liters
(15 quarts) to hold the used oil. Remove the oil drain
plug and drain the used engine oil into the container.
