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

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

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