Bedplate

This is a structural casting bolted to the bottom of the cylinder block to retain the crankshaft and to further improve overall rigidity.

Slight changes to main bearing clearance due to expansion are minimized by means of iron inserts cast into the bedplate main bearing supports.

Two hollow dowels align the bedplate with the cylinder block and the joint is sealed by a continuous bead of sealant.

The engine speed sensor is located at the rear of the bedplate and is a variable reluctance sensor that provides an input to the ECM representing engine crankshaft speed and position.
