1.5 and 3.0 mm thick washers at lower left-hand drive roll position only, must be machined and hardened to keep the shaft end center bolt tight.

When replacing drive sprocket, the procedure for installing center bolt and washers in left-hand drive roll must be followed to avoid loosening of center bolt.

Make note of all washers and spacers when removing drive roll bearing. To ensure a proper joint, replace with new washers. The exact number of washers and spacers must be installed in the same order and in same location as removed when drive roll bearing is installed.
