Allocating Main Bearing Shells for Used and Reworked Crankshafts

Allocation of Bearing Shells for Cylinder Block





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

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

• Basic dimension of main crankshaft journals = 65.00 mm diameter.

• Repair stage of main crankshaft journals = 64.75 mm diameter.

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





Allocation of Bearing Shells for Guide Frame

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

• Any other markings on the crankshaft are invalid when reworking crankshafts.

• Allocate bearing shells to the determined diameter of main crankshaft journals according to the following table.
