Service Intervals; Conveying Belt Tension - HARVEST FC1545 Operator's Manual

!
4C Service Intervals
8 Hours or Daily:
1. Lubricate all roller bearings.
2. Check gas engine drive belt tension. The belts should deflect 1/4" with 5 lbs force at the
center of the span.
3. Check conveyor belt tension and alignment.
4. Check drive chain tension.
5. Check belt lacing.
50 Hours or Annually:
1. Lubricate the drive chain.
2. Check wheel bearing tightness & repack if necessary.

4D Conveying Belt Tension
Proper belt tension depends on several factors. The main two are 1) the commodity being
conveyed and 2) the capacity at which the conveyor is running. At greater capacities, the belt
needs to be tightened to prevent slipping. In the same way, when moving a heavier product,
the belt also must be tightened.
The tension and alignment of the belt should be checked daily (if not more often). A
properly tensioned belt will not slip while in operation. It is the operator's responsibility
to ensure there is no slippage while in use.
A new belt requires more care than one that has been broken in. Within the first 10 hours of
operation, the belt will stretch and contract. After these first ten hours, the belt tension
requires much less observation.
ADJUSTING THE BELT TENSION:
NOTE: This is only a starting point. Belt tension must be closely monitored throughout first 10
hours of operation and daily after those first 10 hours.
WARNING: Failure to follow these steps will result in serious damage to the
conveyor. A belt that is too tight results in bearing failure and belt failure. A
belt that is too loose results in damage to drive roller and conveyor belt.

1. Disable the gas engine before adjusting belt tension.
