CRANKSHAFT
DESCRIPTION
The crankshaft used for the 2.5L is a forged steel
design with five main bearing journals (Fig. 40). The
crankshaft used for the 2.8L is of the same basic con-
struction and design except the rear alignment pin is
shorter (0.12mm) and the rear crankshaft diameter is
slightly larger (0.33mm) (Fig. 41). These crankshafts
ARE NOT interchangable. The crankshaft is located
at the bottom of the engine block and is held in place
with three main bearing supports
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder bores to the flywheel or
flexplate.
STANDARD PROCEDURE - CHECKING
CRANKSHAFT END PLAY
NOTE: Checking crankshaft end play is similar for
both the 2.5L and the 2.8L.
(1) Mount a dial indicator to a stationary point at
rear of engine. Locate the probe perpendicular
against the flywheel or flex plate (Fig. 42).
(2) Move the crankshaft all the way to the front of
its travel.
(3) Zero the dial indicator.
(4) Move the crankshaft all the way to the rear
and read dial indicator. For crankshaft end play
clearances (Refer to 9 - ENGINE - SPECIFICA-
TIONS) .
