Allocation of Main Bearing Shells for Used and Reworked Crankshafts

Allocation of Crankshaft Bearing Shells for Cylinder Block





• Bearing shells are allocated to cylinder block corresponding to color markings stamped into cylinder block.

• For worn and reworked crankshafts, the crankshaft journals must be measured in order to allocate the matching bearing shells.

• Crankshaft journal diameter = dia. 65.00 mm.

• Repair stage crankshaft journal = dia. 64.75 mm.

• Thicker over-sized bearing shells are available for reworked crankshafts. These have the same color markings as the original-size bearing shells.





Allocation of Crankshaft Bearing Shells for Guide Frame

• For worn and reworked crankshafts, the crankshaft journals must be measured in order to allocate the matching bearing shells.
