Routine Maintenance
Pulley / Roller Replacement
Procedure:
1) Unplug power to the Conveyor.
2) Loosen the Shaft from the Rail with a ½” wrench.
3) Turn the Shaft out with your fingers.
4) Place a new Roller and/or Pulley on the Shaft.
5) Make sure that the shoulder of the Shaft extends past the Pulley to prevent
the Pulley from being pinched against the Rail (See below).
6) Turn the Roller Assembly into the rail with your fingers until snug.
7) Using a Torque Wrench set to 32 inch/pounds, tighten the Roller Assembly.
8) Hand spin the Pulley and Roller to make sure they spin freely and are not
being pinched into the Rail.
9) Restore power to the Conveyor.

Collar Clamp Removal
Procedure:
1) Unplug power to the Conveyor.
2) Remove the 4-40 x ¼” Socket Head Cap (SHC) Screws from the Collar Clamp.
(2 screws for narrow clamps, 4 screws for wider clamps)
3) Pry the pieces apart using a small, straight-blade screwdriver.
Collar Clamp Assembly
Procedure:
1) Unplug power to the Conveyor.
2) Check the Drive Side and Passive side Pulleys for proper position. The Pulleys
should be against the Rails.
3) Place one Clamp piece on the Pulleys. Be sure that the piece is as close to centered
as possible.
4) Place the other Clamp piece on in alignment with the first piece.
5) Tighten the Collar Clamp in place by using the following procedure:
a) Tighten one 4-40 x ¼” SHC Screw until snug.
b) Tighten the second screw until snug.
c) Fully tighten the first screw.
d) Fully tighten the second screw.
Note: 1.)Three piece clamps use four screws, two at each end. Tighten screws gradually
and evenly while keeping parts centered. Rotate the assembly by hand to check.
2.) Clamps 1.50”— 2.50” use 1 FHCS.
This diagram is of a two piece clamp. Three piece clamps are similar.

Motor Pulley Gauging
Important: This procedure is for Belt Drive models.
Many problems can occur if the Motor Pulley and the Drive Side Pulley are not properly
aligned. Problems created by running a Conveyor with a poorly aligned Drive Belt include:
1) Worn Drive Components
2) Debris accumulation from pulley wear.
3) Drive Belt breakage
4) Belt noise
5) High current draws
The importance of proper Drive Belt alignment cannot be overstated. Therefore, Motor
Pulleys should be gauged every time that the Drive Belt is removed or whenever it can easily
be gauged as part of another maintenance procedure.
Please Note: Make sure that the proper Gauge is being used.
Procedure:
1) Unplug power to the Conveyor.
2) Remove the Drive Belt (See Page 13).
3) Slide the Gauge (*Not Provided) between the Motor Pulley and the Motor
Mount. If the gauge* slides in and fits snugly, the Motor Pulley is positioned
correctly, skip to procedure number 7. If not, continue to procedure number 4.
4) Loosen the set screw(s) on the Motor Pulley.
5) Slide the Gauge* between the Motor Pulley and the Motor Mount.
6) With the Motor tightly held to the Motor Mount, press the Motor Pulley and
Gauge* to the Motor Mount, tighten the set screw(s).
7) Slide the Gauge* out.
8) Attach the Drive Belt (See Page 13).
9) Visually confirm that the Drive Belt is aligned vertically on the Motor Pulley and
Drive Side Pulley.
