Crankshaft
Tools
Use the tool kit 544 10 36-02 to press
the crankshaft into the bearing, after first
fitting this in the relevant crankcase half.
The threaded mandrel for the clutch and
flywheel side is M10V and M8x1, respec-
tively.
Assembly
Pictures 1 and 2.
Secure the crankcase half with the cylinder
base plane facing downwards so that the
connecting rod is not forced against the
crankcase while working. Slide the crank-
shaft in the bearing.
Picture 3.
Position the sleeve from the tool kit
against the crankcase half. Screw the
threaded mandrel on the crankshaft by
hand until it bot toms. Note that the
crankshaft has a left-hand thread on the
clutch side.
Picture 4.
Lock the threaded mandrel's movement
and press in the crankshaft by turning
the nut until the bearing reaches the stop
in the crankcase half. Make sure that the
connecting rod is not held against the
crankcase half.
Picture 5.
Fit the guides.
Picture 6.
Fit the new crankcase gasket.
Picture 7.
Assemble the other crankcase half using
the same method as the first. Change to
the other threaded mandrel.
IMPORTANT! Pay attention to the
position of the connecting rod while
tightening so that this does not get jam-
med in position. Also align the guides in
time so that the crankcase gasket is not
damaged. Prefit the screws before the
crankcase halves are brought together to
guide the gasket into place.
Picture 8.
Fit the screws and tighten these crosswise
to a torque of 8–9.5 lbf·ft/ 11–13 Nm.
Check that the crankshaft runs free
after assembly. Knock the ends of the
shaft using a small plastic hammer usu-
ally releases any tension.
Picture 9.
Cut the gasket at the cylinder face.
Bild 10.
Fit new stuffing boxes (page 36).
Once the cylinder has been assembled
the crankcase should be leakage tested.
