General Information
The crankshaft is a balanced, forged-steel unit. Four-
cylinder engines have five main bearings. Six-cylinder en-
gines have seven main bearings. The lower bearing shells
are all the same. All of the upper bearing shells are also the
same with the exception of the journal adjacent to the rear
one. The next to last journal is fitted with a flanged upper
bearing shell. The flanges control the end thrust of the
crankshaft.
