The crankshaft runs in four bearings with clamped two layer bearing shells. The upper and lower shells of bearing number 4 are flanged, which limits the end float of the crankshaft. The main bearing caps are double bolted and cross bolted to increase the strength and rigidity of the engine block.

The main bearings are selective split plain bearings. An oil groove in the top half of each bearing transfers oil into the crankshaft for lubrication of the connecting rod bearings.

The crankshaft rear seal and retainer assembly is a one-piece unit and is supplied with its own fitting sleeve. The seal and retainer have two locating dowels, ten fixing bolts and a seal. In addition, the retainer has a location for the Crankshaft Position Sensor (CKP). For additional information, Refer to: ELECTRONIC ENGINE CONTROLS

Crankshaft Reluctor Ring

The crankshaft reluctor ring is located on the rear of the crankshaft. It is pressed onto the crankshaft using a special tool, which also precisely aligns the reluctor ring for crankshaft position and timing.

The crankshaft reluctor ring consists of 60 magnets minus 2 for Powertrain Control Module (PCM) crankshaft position reference and synchronization. The magnets cannot be seen on the reluctor ring, which therefore can only be positioned using the special tool.

If the reluctor ring is removed for any reason, then a new reluctor ring must be fitted.

Crankshaft Pulley/Mass Damper 

The crankshaft pulley/mass damper is bolted to the front of the crankshaft to provide the drive for the engine accessory components. For additional information, Refer to: ACCESSORY DRIVE
