NOTE: TECHNICAL INFORMATION
Observe the classification of the bearing shells.
The code letters of the crankshaft and crankcase mark the classification of the bearing shell for the respective bearing position.
The letters from the crankcase and crankshaft are required to determine the bearing shell colors.
The first letter from the left applies to the first bearing position on the timing chain drive system.
Bearing seat 3 is designed as a guide bearing.

Observe the assignment of classification of the bearing seats (1) to (5) on the crankshaft:

Bearing seat:
Bearing seat 1
Bearing seat 2
Bearing seat 3 (guide bearing)
