Note
The upper connecting rod bearing shells for
engines 603.96 are made using a different
material starting due to the higher load.
Caution!
Do not mix the upper and lower bearing shells.
They can be recognized by the stamped-in part
number.
Upper bearing shells
603 08 10
or
603 15 10
Lower bearing shells 601 04 11
or 601 08 11
The bore for lubrication of the piston pin has
been eliminated.
Due to higher loads in engine 603.970, the
upper connecting rod bearing shells are made of
a different material than the lower shells.
To prevent the upper locating
groove is
0.7
mm narrower.
15 Measure connecting rod bearing diameters
and note.
16 Measure connecting rod bearing journals.
Determine connecting rod bearing radial
clearance.
The bearing clearance can be corrected by
changing the bearing shells, whereby it should
be attempted to achieve the mean value of the
specified bearing clearance. Observe different
wall thicknesses.
