2005 CHRYSLER CARAVAN checking oil

Upper and lower number 2 bearing halves are
flanged to carry the crankshaft thrust loads and are
NOT interchangeable with any other bearing halves
in the engine (Fig. 69). All bearing cap bolts removed
during service procedures are to be cleaned and
lubricated with engine oil before installation. Bearing
shells are available in standard and the following
undersizes: 0.025 mm (0.001 in.) and 0.254 mm
(0.010 in). Never install an undersize bearing that
will reduce clearance below specifications.
CRANKSHAFT BEARING OIL CLEARANCE
Inspect the crankshaft bearing journals. (Refer to 9
- ENGINE/ENGINE BLOCK/CRANKSHAFT -
INSPECTION)
Engine crankshaft bearing clearances can be deter-
mined by use of Plastigage or the equivalent. The fol-
lowing is the recommended procedures for the use ofPlastigage with the engine in the vehicle or engine
on a repair stand.
PLASTIGAGE METHODÐENGINE IN-VEHICLE
NOTE: The total clearance of the main bearings can
only be determined with the engine in the vehicle
by removing the weight of the crankshaft. This can
be accomplished by either of two following meth-
ods:
(1) Preferred method:
a. Shim the bearings adjacent to the bearing to be
checked in order to remove the clearance between
upper bearing shell and the crankshaft. This can be
accomplished by placing a minimum of 0.254 mm
(0.010 in.) shim (e. g. cardboard, matchbook cover,
etc.) between the bearing shell and the bearing cap
on the adjacent bearings and tightening bolts to
14±20 N´m (10±15 ft. lbs.).
²When checking #1 main bearing shim #2 main
bearing.
²When checking #2 main bearing shim #1 & #3
main bearing.
²When checking #3 main bearing shim #2 & #4
main bearing.
²When checking #4 main bearing shim #3 main
bearing.
NOTE: Remove all shims before reassembling
engine.
(2) Alternative Method:
a. Support the weight of the crankshaft with a
jack under the counterweight adjacent to the bearing
being checked.
(3) Remove oil film from surface to be checked.
Plastigage is soluble in oil.
(4) Place a piece of Plastigage across the entire
width of the bearing shell in the cap approximately
6.35 mm (1/4 in.) off center and away from the oil
holes (Fig. 70). (In addition, suspected areas can be
checked by placing the Plastigage in the suspected
area). Torque the bearing cap bolts of the bearing
being checked to the proper specifications.
(5) Remove the bearing cap and compare the width
of the flattened Plastigage (Fig. 71) with the scale
provided on the package. Locate the band closest to
the same width. This band shows the amount of
clearance in thousandths. Differences in readings
between the ends indicate the amount of taper
present. Record all readings taken. (Refer to 9 -
ENGINE - SPECIFICATIONS)Plastigage gener-
ally is accompanied by two scales. One scale is
in inches, the other is a metric scale.

NOTE: Plastigage is available in a variety of clear-
ance ranges. Use the most appropriate range for
the specifications you are checking.
PLASTIGAGE METHODÐENGINE OUT-OF-VEHICLE
(1) With engine in the inverted position (crank-
shaft up) and mounted on a repair stand, remove
main journal cap.
(2) Remove oil from journal and bearing shell.
(3) Cut Plastigage to same length as width of the
bearing and place it in parallel with the journal axis
(Fig. 70).
(4) Carefully install the main bearing cap and
tighten the bolts to specified torque.
CAUTION: Do not rotate crankshaft or the Plasti-
gage will be smeared.
(5) Carefully remove the bearing cap and measure
the width of the Plastigage at the widest part using
the scale on the Plastigage package (Fig. 71). Refer
to Engine Specifications for proper clearances (Refer
to 9 - ENGINE - SPECIFICATIONS). If the clearance
exceeds the specified limits, replace the main bear-
ing(s) with the appropriate size, and if necessary,
have the crankshaft machined to next undersize.
REMOVAL - CRANKSHAFT MAIN BEARINGS
(1) Remove the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - REMOVAL)(2) Identify main bearing caps before removal.
(3) Remove bearing caps one at a time. Remove
upper half of bearing by inserting Special Main Bear-
ing Tool C-3059 (Fig. 72) into the oil hole of crank-
shaft.
(4) Slowly rotate crankshaft clockwise, forcing out
upper half of bearing shell.
INSTALLATION - CRANKSHAFT MAIN
BEARINGS
NOTE: One main bearing should be selectively fit-
ted while all other main bearing caps are properly
tightened.
(1) For main bearing fitting procedure, (Refer to 9

TORQUE CONVERTER CLUTCH (TCC)
In a standard torque converter, the impeller and
turbine are rotating at about the same speed and the
stator is freewheeling, providing no torque multipli-
cation. By applying the turbine's piston to the front
cover's friction material, a total converter engage-
ment can be obtained. The result of this engagement
is a direct 1:1 mechanical link between the engine
and the transmission.
The engagement and disengagement of the TCC
are automatic and controlled by the Powertrain Con-
trol Module (PCM). The engagement cannot be acti-
vated in the lower gears because it eliminates the
torque multiplication effect of the torque converter
necessary for acceleration. Inputs that determine
clutch engagement are: coolant temperature, vehicle
speed and throttle position. The torque converter
clutch is engaged by the clutch solenoid on the valve
body. The clutch will engage at approximately 56
km/h (35 mph) with light throttle, after the shift to
third gear.
REMOVAL
(1) Remove transmission and torque converter
from vehicle. (Refer to 21 - TRANSMISSION/TRANS-
AXLE/AUTOMATIC - 41TE - REMOVAL)
(2) Place a suitable drain pan under the converter
housing end of the transmission.
CAUTION: Verify that transmission is secure on the
lifting device or work surface, the center of gravity
of the transmission will shift when the torque con-
verter is removed creating an unstable condition.
The torque converter is a heavy unit. Use caution
when separating the torque converter from the
transmission.
(3) Pull the torque converter forward until the cen-
ter hub clears the oil pump seal.
(4) Separate the torque converter from the trans-
mission.
INSTALLATION
Check converter hub and drive notches for sharp
edges, burrs, scratches, or nicks. Polish the hub and
notches with 320/400 grit paper or crocus cloth if nec-
essary. The hub must be smooth to avoid damaging
the pump seal at installation.
(1) Lubricate converter hub and oil pump seal lip
with transmission fluid.(2) Place torque converter in position on transmis-
sion.
CAUTION: Do not damage oil pump seal or bushing
while inserting torque converter into the front of the
transmission.
(3) Align torque converter to oil pump seal open-
ing.
(4) Insert torque converter hub into oil pump.
(5) While pushing torque converter inward, rotate
converter until converter is fully seated in the oil
pump gears.
(6) Check converter seating with a scale and
straightedge (Fig. 305). Surface of converter lugs
should be 1/2 in. to rear of straightedge when con-
verter is fully seated.
(7) If necessary, temporarily secure converter with
C-clamp attached to the converter housing.
(8) Install the transmission in the vehicle. (Refer
to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC
- 41TE - INSTALLATION)
(9) Fill the transmission with the recommended
fluid. (Refer to 21 - TRANSMISSION/TRANSAXLE/
