6.  Tighten  the  set  screws,  replace  the  V-belt, 

and  repeat 

Step 3 to  verify  proper  pulley 

alignment.  Pulleys  should  be  parallel  and 
aligned, as shown in 

Figure 37, when belt is 

properly tensioned.

7.  Replace the pulley cover.

Tracking 

Conveyor Belt

The conveyor belt must track straight. If the feed 
belt  tracks  to  either  side,  then  the  tracking  must 
be  corrected  or  the  conveyor  belt  will  become 
damaged and have to be replaced. The tracking 
was properly set at the factory, but it is the respon-
sibility of the end user to keep it tracking properly 
during the life of the machine.

Tracking the conveyor belt is a balancing process 
that  takes  patience  and  a  small  degree  of  trial-
and-error. Usually you must over-tighten the loose 
side (the side the belt is tracking towards) to make 
the conveyor belt move to the middle of the rollers, 
then loosen that same side to make the feed belt 
stay  in  position.  If  you  adjust  the  tracking  screw 
too much either way, then you have to repeat the 
process until the conveyor belt rides in the middle 
and stays there during continuous operation.

Note:  Tracking affects tension, so tension must 
always be adjusted after tracking.

Items Needed 

Qty

Wrench 8mm ......................................................1 
Hex Wrench 4mm ...............................................1

Working around moving conveyor and parts 

presents pinch/entanglement hazards that 

can cause personal injury. Use extreme 

care to keep hands clear of in-running pinch 

points while adjusting tracking nut/screw 

when machine is running. Roll up sleeves 

and do not wear gloves or other apparel that 

could become entangled in moving parts.

To track conveyor belt:

1.  Turn conveyor belt ON and watch it track. 

—If the belt quickly moves to one side, imme-

diately  stop  the  machine  and  adjust  the 
belt  tracking  before  running  the  conveyor 
again. 

 

—If the belt tracks evenly, leave it alone.
