Changing the steering ring
The Quattro-SE may be supplied with a steering ring with either a moulded steering indicator on the top or rivets
on the underside of the steering ring.
To change the steering ring:
1. Fully extend the column and apply the on-shot clamp (20).
2. On the underside of the steering hub (Fig 6), remove four nyloc nuts (3.1) to release the steering ring
(3). Note the position of the steering indicators (19) and remove the steering ring.
3. Position the replacement steering ring on the steering hub with the steering indicator in the position
noted above.
4. Secure the steering ring with four nyloc nuts (3.1).
Note: If a steering ring with a moulded steering indicator is changed for one with rivets, or vice
versa, it will be necessary to realign the steering mechanism. This should be carried out
by competent personnel in accordance with the procedures laid down in the Technical
Manual.
