Adjustment

- Loosen the screws (G) on the upper pla-

te.

- Recover the clearance by intervening on

ring nut F.

- Check that the rotation of the steering

gear takes place in a fluent way. Excessive
tightening of the steering gear bearings
may jeopardise operation.

- Tighten nut E.

To re-secure, proceed in reverse order.

CHAIN TENSION

For  a  longer  life  of  the  final  drive  chain,
we  suggest  you  to  check  its  tension  pe-
riodically.
Always clean off dirt deposits and lubricate it.
If  the  free  clearance  in  the  chain  exceeds
20 mm, it needs tensioning as follows:

- Slack off nut A.

- Adjust with lever B.

- Adjust with the same lever on the opposi-

te side, taking it to the same position.

- Check the wheel alignment.

- Re-tighten nut A.
