Information:
The parts department will be supplying modified crankcases and bearing housing. During repairs, if the crankcase is damaged, the crankcase and the
bearing housing must be replaced together.

Due to the crankcase modifications, the previously installed bearing housing can no longer be used.
This applies for all engines in the model year 99 (X) up to following engine numbers:
M96/01 66 X 11005 or M96/02 68 X 05167
Note:
During installation of a new bearing housing the oil spray jets for piston cooling must also be installed.
The modified bearing housing can be installed retroactively in a pre-modification crankcase.
