Assembly notes

Reinforced connecting rods

Adopted for production from Oct. 1, 1993, as of the following engine numbers:

42 R 00 598 (engine type M 44/43) 42 R 50 621 (engine type M 44/44)

Identification mark:

Reinforced transition area from stem to bolt head seating surface

Connecting rod installation position

The matching numbers must be fitted so that they face each other and remain legible.

The matching numbers of the four connecting rods must be located in one line, i.e. all matching numbers must be located on the same side.

If at least one of the connecting bolt unions is undone during an engine rebuild, the new reinforced connecting rods must always be fitted throughout (if the engine was equipped with the former connection rod version).

These connecting rods are retroactively applicable for spare purposes for all models as of Model Year 1992 (N).
