MOTO GUZZI V10 CENTAURO Werkstatt-Handbuch Seite 137

In order to check the coupling of the pinion and crown,
cover the pinion teeth, on the drive side, with one of
the many products available on the market.
Apply a universal extractor «A» - Fig. 15-17 with an
appropriate spacer «B» - Fig. 15-17, so that the
bored pivot - crown unit is held tightly against the
cover side; rotate pinion «C» - Fig. 15-17 in the
working operation direction, whilst locking the crown.
Remove the extractor, remove the cover and check
the contact zone on the pinion teeth.
Contact control (Fig. 15-18)
■ if the contact is correct the traces on the pinion teeth will be seen as shown in detail 1 (the pinion is seen from
the drive shaft side);
■ if the contact is the same as detail 2 the crown is too near to the pinion rotation axis: move the crown away
by increasing the thickness of the spacers between the box and the cover;
■ if the contact is the same as detail 3 the pinion is too near to the crown rotation axis: move the pinion away
by reducing the thickness of the spacers between the bearings and the pinion;
■ if the contact is the same as detail 4 the pinion is too far away from the crown rotation axis: move the pinion
closer by increasing the thickness of the spacers between the bearings and the pinion;
■ if the contact is the same as detail 5 the crown is too far away from the pinion rotation axis: move the crown
nearer by reducing the thickness of the spacers between the box and the cover;
■ with a correct coupling the play between the pinion teeth and the crown teeth should be between 0.10 mm and
0.15 mm.
