Matching crankshaft bearing shells to bearings in retaining
frame
♦ Bearing shells of the correct thickness are assigned to the
bearing caps at the factory. Coloured dots on bearing shell
are used to identify bearing shell thickness.
♦ The correct allocation of bearing shells to crankshaft is in-
dicated by a sequence of letters on the crankshaft webs.
The number “1” -arrow- preceding the sequence of letters
indicates the colour code for No. 1 bearing.
