CRANKSHAFT
DESCRIPTION
The crankshaft (1) is constructed of nodular cast iron.
The crankshaft is a three throw split pin design with
six counterweights for balancing purposes. The crank-
shaft is supported by four select fit main bearings with
the No. 2 serving as the thrust washer location. The
main journals of the crankshaft are cross drilled to
improve rod bearing lubrication. The No. 6 counter-
weight has provisions for crankshaft position sensor
target wheel (2) mounting. The select fit main bearing
markings are located on the rear side of the target
wheel. The crankshaft oil seals are one piece design.
The front oil seal is retained in the timing chain cover,
and the rear seal is pressed in to a bore formed by
the cylinder block and the bedplate assembly.
