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 seven select 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 select fit main bearing markings are located on the crankshaft counter weights. The crankshaft rear oil seal is a two piece design. The front oil seal is a one piece design retained in the timing chain cover (Fig. 5).
