4.2.8.2 Belt Replacement Procedure
Turn OFF the machine being worked on as well as the machines on each
side of the machine being worked on while replacing the belt.
1. Note the direction of the arrow on the belt. This may be located either on the inside or the
outside of the belt.
a. Place the bounce board assembly inside the belt with the V-shaped cutout toward the ball
exit. The arrow on the belt must point in the direction the belt turns during operation.
b. Wrap the belt around the bounce plate assembly and place it in the pit slightly forward on
the pit support brackets. Do not fasten the bounce plate down at this time.
2. Install the rear roller by passing it from the adjacent machine on the side opposite the ball exit
side of the machine, through the opening in the rear of the kickback plates and through the
belt. The axle of the roller should protrude through the hole in the kickback plate and into the
space occupied by the PBL.
3. Place the rear roller bearings in the bearing supports and hook the handle of the rear roller
support bracket under the retaining tab on the kickback plate.
4. Install the drive pulley and conveyor drive belt.
5. Place the bounce plate in position inserting the studs on the pit support brackets through the
mounting holes in the vibration dampers.
