ENGINE BLOCK
DESCRIPTION
The 2.5L CRD Diesel engine uses a cast iron
engine block with wet cast iron cylinder liners (Fig.
33).
CRANKSHAFT
DESCRIPTION
The crankshaft is a forged steel type design with
five main bearing journals. The crankshaft is located
at the bottom of the engine block and is held in place
with three main bearing supports (Fig. 34).
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder bores to the flywheel or
flexplate.
