CONVEYOR BELT ASSEMBLY AND SERVICE
BREAK-IN AND ADJUSTMENT OF CONVEYOR BELTS
the conveyor belts in the MTS have been pre-tensioned by the factory, prior to delivery, but due to a
stretch factor of up to 1-1/2%, will need to be retensioned after the initial use and possibly, after the
first few uses. Once the belt is broken in, the frequency of need to adjust the belt should be reduced.
SYMPTOM
The symptom of lost tension on the belt is floor slippage during operation, making it difficult to unload
material.
NOTICE
Do not overload the unit beyond reccomended capacity. Failure to comply could result in prod-
uct damage
TOOLS NEEDED
To tighten the floor, you will need a 1-13/16 in., open-ended wrench and a tape measure, scale, or
calipers. At the rear of the machine, you will find a take-up bearing on both sides, as shown below in
Figure 9 (Side Conveyor, use a 15/16-in. wrench).

MAKE ADJUSTMENTS
Prior to making any adjustments, check both bearings and note the measurement per Figure 9. These
numbers may vary from side to side, due to adjustments made for belt tracking. For instance, the first
side may start at 5.25 in. and you tighten to 5.375 in. In this case, you have increased tension by
.125 in.. Therefore, the other side should be increased by 0.125 in. to maintain tracking. If the second
bearing starts at 5.375 in., and you tighten it by 0.125 in., it should be at 5.500 in. after adjustment.
(Reference dimension of 1.750 in. for the side conveyor.)
NOTE: If tracking issues occur, they should be corrected by tightening one
side, not loosening.
Operate unit to see if the slipping issue has been resolved; if not, repeat the procedure until no slipping
is present.
