BEARINGS-CRANKSHAFT MAIN
STANDARD PROCEDURE
MAIN BEARING FITTING
SELECT FIT IDENTIFICATION
The main bearings are “select fit” to achieve proper oil
clearances. For main bearing selection, the crankshaft
position sensor target wheel (2) has grade identifica-
tion marks stamped into it. These marks are read from
left to right, corresponding with journal number 1, 2, 3,
4. The crankshaft position sensor target wheel is
mounted to the number 6 counter weight (1) on the
crankshaft.
INSPECTION
Wipe the inserts clean and inspect for abnormal wear patterns and for metalor other foreign material imbedded in
the lining. Normal main bearing insert wear patterns are illustrated.
Inspect the back of the inserts for fractures, scrapings or irregular wearpatterns.
Inspect the upper insert locking tabs for damage.
Replace all damaged or worn bearing inserts.
MAIN BEARING JOURNAL DIAMETER (CRANKSHAFT REMOVED)
Remove the crankshaft from the cylinder block (Refer to 9 - ENGINE/ENGINE BLOCK/CRANKSHAFT - REMOVAL).
Clean the oil off the main bearing journal.
Determine the maximum diameter of the journal with a micrometer. Measure at two locations 90° apart at each end
of the journal.
The maximum allowable taper is 0.008mm (0.0004 inch.) and maximum out of round is 0.005mm (0.002 inch). Com-
pare the measured diameter with the journal diameter specification (MainBearing Fitting Chart). Select inserts
required to obtain the specified bearing-to-journal clearance.
Install the crankshaft into the cylinder block (Refer to 9 - ENGINE/ENGINEBLOCK/CRANKSHAFT - INSPECTION).
Check crankshaft end play.
CRANKSHAFT MAIN BEARING SELECTION

SWITCH-OIL PRESSURE
DESCRIPTION
The 3 wire, solid-state engine oil pressure sensor (sending unit) is located in an engine oil pressure gallery.
OPERATION
The oil pressure sensor uses three circuits. They are:
A 5 volt power supply from the Powertrain Control Module (PCM)
A sensor ground through the PCM’s sensor return
A signal to the PCM relating to engine oil pressure
The oil pressure sensor has a 3 wire electrical function very much like the Manifold Absolute Pressure (MAP) sen-
sor. Meaning different pressures relate to different output voltages.
A 5 volt supply is sent to the sensor from the PCM to power up the sensor. The sensor returns a voltage signal
back to the PCM relating to engine oil pressure. This signal is then transferred (bussed) to the instrument panel on
either a CCD or PCI bus circuit (depending on vehicle line) to operate the oil pressure gauge and the check gauges
lamp. Ground for the sensor is provided by the PCM through a low-noise sensor return.
REMOVAL
1. Disconnect the negative cable from the battery.
2. Raise vehicle on hoist.
3. Remove front splash shield.
4. Disconnect oil pressure sender wire (4).
5. Remove the pressure sender (2).
INSTALLATION
1. Install oil pressure sender.
2. Connect oil pressure sender wire.
3. Install front splash shield.

5. Connect the negative battery cable.

MANIFOLD-INTAKE
DESCRIPTION
The intake manifold (2) is made of a composite mate-
rial and features 300 mm (11.811 in.) long runners
which maximizes low end torque. The intake manifold
uses single plane sealing which consist of six individ-
ual press in place port gaskets to prevent leaks. The
throttle body attaches directly to the intake manifold.
Eight studs and two bolts are used to fasten the intake
to the head.
DIAGNOSIS AND TESTING -INTAKE MANIFOLD LEAKS
An intake manifold air leak is characterized by lower than normal manifoldvacuum. Also, one or more cylinders may
not be functioning.

WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR THE FAN. DO NOT WEAR
LOOSE CLOTHING.

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.
