Service Procedures
Journal Grinding
MAIN JOURNAL
All main journals are to be ground in the opposite direction of engine rotation (clockwise as viewed from the front of crankshaft). Polish the journals
in the same direction as engine rotation.
Crankshaft Main Journal Dimensions
The main bearing grinding specifications are shown.
Crankshaft Thrust Journal Width Dimensions
Thrust journals can be ground in the same increments and using the same specifications as all other main journals. The main journal radius may be
ground using either the preferred or the alternative procedure providing the thrust surface width is not being ground. The preferred procedure must be
used when the main bearing thrust width surface is ground. When the thrust surface width requires grinding, the main journal must be ground to the
same undersize dimension.
