6. Uncouple the top conveyor main drive shaft from the top module drive
shaft. Draw the top module drive shaft back through the flanged bearing
until it is clear of the top conveyor main drive shaft.
7. Remove the four lower conveyor assembly fixing screws from beneath the
top module. Carefully extract the top conveyor main drive shaft and lower
conveyor assembly from the top module. Place the lower conveyor assem-
bly on a suitable work surface.
8. Disengage the top divert belts and remove the main drive shaft from the
top conveyor assembly.
9. Remove the e-clips, spacer washers and plastic bearings from the L/H ends
of the two tower link assembly divert shafts.
10. Remove the e-clip and nylon spacer from the L/H end of the tower link
assembly pivot shaft. Withdraw the L/H pivot shaft and steel spacer tube
from the end of the pivot shaft.
11. Remove the inner e-clip and nylon washers from the pivot shaft.
12. Using a plastic mallet, gently tap the end of the pivot shaft and drive the
flanged bearing out of the R/H side plate.
13. Push all of the unfastened shafts towards the R/H side plate of the top
divert bracket and disengage them from the L/H side plate. Remove the
four conveyor belts by slipping them over the L/H ends of the shafts.
14. Replace the conveyor belts with four new ones and reassemble the
machine in the reverse order to the removal procedure. Ensure that all
removed e-clips are replaced with new ones.
