Connecting Rod Weight Group Specifications





The con-rods are allocated to weight classes. The last digit of the part number indicates the weight class. The last digit is marked on the shaft of con-rods supplied as spare parts.

NOTE:
^ The weight difference between con-rods installed in the same engine must not exceed 6 g. To determine the weight class, weigh the entire con-rod without the bearing shells.

^ The con-rod markings for spare parts are stamped with paint.

Type 1 and 2 con-rods are no longer available as spare parts. If con-rods need to be replaced, a complete set of type 3 con-rods must be installed.

NOTE: Type 3 con-rods are also available as individual parts.
