CRANKSHAFT
DESCRIPTION
The crankshaft is constructed of nodular cast iron. The crankshaft is a crosshaped four throw design with eight
counterweights for balancing purposes. The crankshaft is supported by five select fit main bearings with the number
three serving as the thrust washer location. The main journals of the crankshaft are cross drilled to improve rod
bearing lubrication. The number eight counterweight has provisions for crankshaft position sensor target wheel
mounting. The select fit main bearing markings are located on the rear sideof 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.

ing halves. Use care when handling bedplate as
not to drop or damage bearing halves. Installing
main bearing halves in the wrong position will
cause sever damage to the crankshaft.
