3.6.11 DRIVING SHAFT

Carefully read 0.2.1 (PRECAUTIONS AND GENERAL
INFORMATIONS).
Check the wear of the driving shaft:
– section for main bushes (1);
wear limit min. Ø 45.955 mm;
– section for support bushes (2);
wear limit min. Ø 29.970 mm;
– housing of the freewheel gear bearing (3)
wear limit min. Ø 34.960mm;
– connecting rod small end (4);
wear limit max. Ø 22.030 mm;
– end play between connecting rod and crank arm (5);
wear limit max. 0.60 mm;
– driving shaft eccentricity, flywheel side (6);
limit max. 0.020mm;
– driving shaft eccentricity, clutch side (7);
limit max. 0.020 mm.
NOTE
Measure the eccentricity of the driving shaft be-
tween the ends.
End play of the driving shaft max. 0.5 mm.
NOTE
Use a comparator to determine the end play of
the driving shaft once the two halves of the casing are
coupled.
Determine the radial play (8) from the eye of the con-
necting rod with a comparator.
Wear limit: max. 0.060 mm.
Measure the radial play of the two main bush halves
(1).
Max. permissible radial play 0.060 mm.
NOTE
If the max. permissible radial play is exceeded,
the worn part must be replaced.
The radial play is determined based on the following
values:
maximum value of the main bushes diameter in the en-
gine casing minus the driving shaft diameter at the main
bush housing.
Measure the main bush diameter, see 3.6.5 (ENGINE
HALF-CASING - MAIN BUSHES, DRIVING SHAFT
AND COUNTERSHAFT).
Measure the radial play of the support bushes (2).
Permissible radial play max. 0.065 mm.
NOTE
The radial play of the support bushes is calculat-
ed based on the following values:
maximum value of the diameter of the bushes in the
clutch cover minus the diameter of the driving shaft in the
support bushes area.
Measure the support bush diameter, see 3.5.8 (RE-
MOVING THE CLUTCH COVER).
a
CAUTION
If the max. permissible radial play is exceeded, the
worn part must be replaced.
The following components must also be checked for wear
or broken material:
Key (9) and grooves in the driving shaft.
Colouring of a bearing housing.
Cone surface (10) of the driving shaft section on the fly-
wheel side.
Clean the thread (11) of any LOCTITE
make sure it is in a perfect state of repair.
Check to make sure the bush (12) inside the connect-
ing rod small end is correctly installed and centred (on
the longitudinal axis).
