(4) Tighten the bolts to 27 N´m PLUS 1/4 turn (20
ft. lbs. PLUS 1/4 turn)Do not use a torque
wrench for last step.

CRANKSHAFT
DESCRIPTION
The crankshaft is made of nodular cast iron and
includes five main bearing journals and four connect-
ing rod journals (Fig. 46). The number three journal
is the location for the thrust bearing. The mains and
connecting rod journals have undercut fillet radiuses
that are rolled for added strength. To optimize bear-
ing loading, eight counterweights are used.
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder to the flywheel or flex-
plate.

(2) Move crankshaft all the way to the rear of its
travel.
(3) Zero the dial indicator.
(4) Move crankshaft all the way to the front and

ENGINE 3.3/3.8L
DESCRIPTION
The 3.3 Liter (201 cu. in.) and 3.8 Liter (231 cu.
in.) engines are 60É V-6 engines with cast iron cylin-
der blocks and aluminum cylinder heads (Fig. 1). The
engine uses a single, block mounted camshaft with
pushrods to actuate the valves. These engines do not
have provisions for a free wheeling valve train.The firing order is 1±2±3±4±5±6. The cylinders are
numbered from the front of the engine to the rear.
The front cylinder bank is numbered 2, 4, and 6. The
rear cylinder bank is numbered 1, 3, and 5.
The engine identification number is located on the
rear of the cylinder block just below the cylinder
head (Fig. 2).

DESCRIPTION - 3.8L
The nodular iron crankshaft is supported by four
main bearings, with number two position providing
thrust bearing location (Fig. 52). 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. 52). Crank-
shaft end sealing is provided by front and rear rub-
ber seals.
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder to the flywheel or flex-
plate.
