PREVENTIVE CARE
1) WASH
the two crankcases and the bearings with petrol and blow them with compres-
sed air, checking that the bearings run freely and noiselessly.
CAUTION: if it should be necessary to replace a bearing, the seat must be
heated before installing the new bearing.
2) MAKE SURE
the connecting rod is in perfect working order and check for faults, espe-
cially in the bearing seats. Make sure assembly on flywheel side has been properly accomplis-
hed. Using a comparator, check the eccentricity of the two connecting rod axle shafts. The
maximum eccentricity value must not exceed 0.04 mm. On the contrary, centre accordingly.
Make sure the connecting rod is perpendicular.
3) MAKE SURE
the transmission is in perfect working order and fit the shim washers in
the right positions. If you have replaced components, make sure that they are put in the
same positions as the parts removed and that the end float does not exceed 0.1 mm. To
obtain this condition, measure the distance of the shim washers on the crankcase and com-
ponents, and fill any gaps with other shim washers, as shown in the photo (F-28).
4) CHECK
the distance of the shim washer of the desmodronic shaft both on the crankcase
and on the part, and fill any gaps with other shim washers, as shown in the photo (F-29).
The end float must be less than 0.1 mm.
5) CHECK
the distance of the shim washers of the shift shaft both on the crankcase and
on the part, and fill any gaps with other shim washers, as shown in the photo (F-30). The
end float must be less than 0.1 mm.
