Camshaft and Drive System
A billet steel 1-piece camshaft is supported by 5 bearings pressed into the engine block. The camshaft has a
machined camshaft sensor reluctor ring incorporated between the fourth and fifth bearing journals. The
camshaft timing sprocket is mounted to the front of the camshaft and is driven by the crankshaft sprocket
through the camshaft timing chain. The crankshaft sprocket is splined and drives the oil pump driven gear. A
retaining plate mounted to the front of the engine block maintains camshaft location.
Crankshaft
The crankshaft is cast nodular iron. The crankshaft is supported by 5 crankshaft bearings. The bearings are
retained by crankshaft bearing caps which are machined with the engine block for the proper alignment and
clearance. The crankshaft journals are undercut and rolled. The center main journal is the thrust journal. A
