10) Timing the conditioning rollers after having removed the upper roller drive gearbox

If at any time it becomes necessary to remove the upper roller drive gearbox, then the following procedure
must be followed when reinstalling this gearbox to be sure the rollers are timed correctly and the gearbox
pulley has been installed correctly.
1. Slide the gearbox on the roller drive shafts.
2. Attach the gearbox using 2 screws (1) and 2 nuts (2).
3. Attach the link (3) on the gearbox with screw (4) and washer (5).
4. Lock the rollers using wooden wedges (6) by centring the upper roll in the lower roll, with equal distance between

the lugs and grooves of the opposite roll.

5. Thoroughly degrease the contact area between mounting surfaces of pulley (7)and pinion (8) using a grease

eliminator  such as Loctite 7063.

6. Apply a Loctite 638 retaining product on these mounting surfaces.
7. Install pulley (7),washer (9), and nut (10) using socket (11) and pulley locking lever (12). Torque to 30 daNm/220

ft.lbs.

8. Do not put the machine into service before 24 hours after having installed the gearbox, to allow the bonding

adhesive to cure completely and develop good strength.
