MANUAL OUTER FOLD ROLLERS Section 8<br />
Remove the nut and washer securing the spring block and remove<br />
the block, taking care to hold the spring to avoid losing it and the<br />
spring pad.<br />
Release both grub screws in both the large gear and the drive<br />
gear, five full turns, to clear the shaft and remove the gear.<br />
Remove the calliper jaw by removing the two socket head cap<br />
screws.<br />
Remove the two bolts securing the linear bearings to the backplate<br />
and remove both bearings and back-plate.<br />
The calliper and roller may now be released from the side-frames<br />
and the calliper can be pulled off the roller bearing.<br />
The drive side bearing and calliper remain undisturbed.<br />
Note ........Take care of the circular shims that are fitted between<br />
the calliper and the bearing. They should be kept safe<br />
and used when replacing the roller.<br />
The roller is replaced in the reverse sequence. However, before<br />
fitting and setting the pressure spring, the linear bearings must be<br />
correctly adjusted - see the following sections for the procedures.<br />
8.2 .......Outer Fold Rollers - Linear Bearings<br />
The fold rollers are located in moving callipers which must move<br />
freely up and down without any lateral movement.<br />
This is achieved by setting the linear bearings very carefully which<br />
is carried out at the factory and will require no further attention<br />
unless the rollers are removed.<br />
Before any attempt is made to set the linear bearings, the pressure<br />
spring must be removed,(as in section 8.1 above). This is so that it<br />
is easier to feel the tightness or slackness in the moving calliper.<br />
