Matching crankshaft bearings, installing
crankshaft
Note
These operations should be performed if the
dimensions of the crankshaft journals or of the
basic bearing bores in the crankcase and at the
are not known, e.g. if the crankshafts
have been remachined.
All the bearing covers fit into the side of the
crankcase (arrows) and are attached each with
2 bolts.
The fit (arrows) is offset from the center so that
the bearing covers can only be installed in one
position.
In addition, they are marked from front to rear
with the code numbers 1, 2, 4 and 5 (arrows),
with the exception of the thrust bearing covers,,
and must not be interchanged or replaced.
1
Install crankshaft bearing covers without
bearing shells.
2
Oil fastening bolts for crankshaft bearing
covers and tighten to 90 Nm (hexagon bolts) or
55 Nm initial torque and
angle of rotation
torque (stretch bolts), respectively.
3
Measure basic bore in two planes in the
direction A, B and C (conicity).
If a basic bore exceeds the specified value or is
conical, dress the mating face of the bearing
cover on a surface plate to max. 0.02 mm.
