BELTS&PULLEYS

NEVER MAKE ADJUSTMENTS TO V-BELTS AND PULLEYS WHILE ENGINE IS RUNNING

1. The best tension for a v-belt drive is the lowest tension at which the belts will

not slip under full load.

2. Take up tension until the belts are snug in the grooves. Run the drive for about

five (5) minutes to “seat" the belts. The impose the peak load. If the belts slip, tighten

them until they no longer slip at peak load. Most new belts will need additional

tensioning after seating.

3. Remember, too much tension shortens belt and bearing life.

4. Check the belt tension frequently during the first day of operation. Check the

belt tension periodically thereafter and make any necessary adjustments.

5. The two most common causes of sheave misalignment are:

- the engine drive shaft and the blade shaft are not parallel.

- the pulleys are not located properly on the shafts.

6. To check alignment, use a steel straight edge. See Figure 1.

Fig.1

7. Line up the straight edge along the outside face of both pulleys shown in the

drawing. All pulleys have (2) set screws in the bottom of their grooves. Set screws require

thread locking lock title.
