Installing the Belt
To install a new belt, reverse the above instructions,
but keep in mind the following important notes and
instructions.
Important:
The conveyor belt is designed to
work primarily in one direction. Ensure that the
painted arrow in the middle of the belt is pointing
toward the rear of the machine (looking down
from above).
Note:
Before sliding the rear drive roller back up
through the slot and into place, ensure that you
have already installed the four bolts (from the inside
facing out) for connecting the pillow block bearings.
Otherwise, you must remove the drive roller to gain
enough clearance to install these bolts.
•
When installing the rear drive roller, ensure that
the shaft connecting to the motor is on the left
side. It has a keyhole cut into it for securing the
drive sprocket.
•
Before applying tension with the tensioner rods
at the front of the machine, use your hands to
manually center the belt at the front and rear.
•
Track and tension the belt by following the
instructions in

•
The front idler and rear drive rollers provide
excellent traction for pulling the belt under load.
Important:
Do not overtighten or stretch the
belt.
•
Apply silicone sealer to the rear side of the metal
rails and at the two front corners of the floor where
the rails meet. The sealer deflects any material
from getting past the rails.
