2004 CHRYSLER VOYAGER engine

(1) For main bearing fitting procedure, (Refer to 9
- ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN
BEARINGS - STANDARD PROCEDURE)
(2) Start bearing in place, and insert Main Bearing
Tool C-3059 into oil hole of crankshaft (Fig. 71).
(3) Slowly rotate crankshaft counterclockwise slid-
ing the bearing into position. Remove Special Main
Bearing Tool C-3059.
(4) Inspect main cap bolts for stretching (Fig. 72).
Replace bolts that are stretched.
NOTE: The main cap bolts should be examined
before reuse. Bolt stretch can be checked by hold-
ing a scale or straight edge against the threads. If
all the threads do not contact the scale the bolt
must be replaced (Fig. 72).
(5) Install each main cap and tighten bolts finger
tight.
(6) Tighten number 1, 3 and 4 main cap bolts to 41
N´m + 1/4 Turn (30 ft. lbs.+ 1/4 Turn).
(7) Rotate the crankshaft until the number 6 pis-
ton is at TDC.
(8) To ensure correct thrust bearing alignment the
following procedure must be done:
a. Move crankshaft all the way to the rear of its
travel.
b. Then, move crankshaft all the way to the front
of its travel.
c. Wedge an appropriate tool between the rear of
the cylinder block and rear crankshaft counter-
weight. This will hold the crankshaft in it's most for-
ward position.
d. Tighten the #2 Thrust Bearing cap bolts to 41
N´m + 1/4 Turn (30 ft. lbs.+ 1/4 Turn). Remove the
holding tool.
(9) Install oil pan. (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - INSTALLATION)
(10) Fill engine crankcase with proper oil to cor-
rect level.CRANKSHAFT
DESCRIPTION
DESCRIPTION - 3.3L
The nodular iron crankshaft is supported by four
main bearings, with number two position the thrust
bearing (Fig. 75). Crankshaft end sealing is provided
by front and rear rubber seals.
DESCRIPTION - 3.8L
The nodular iron crankshaft is supported by four
main bearings, with number two position providing
thrust bearing location (Fig. 76). Each main bearing
cap has two vertical retaining bolts. The two center
main caps have horizontal bolts to add increased
rigidity to the lower engine block (Fig. 76). Crank-
shaft end sealing is provided by front and rear rub-
ber seals.
