belts and pulleys of road cutter
- A v-belt drive should be tensioned so that the belts won’t slip under full load at their lowest tension.
- Tighten the bolts until they are snug in the grooves. To “seat” the belts, run the drive for 5 minutes. Apply the maximum load. Tighten the belts until they do not slip under peak load. Once the belts have been installed, they will require additional tensioning.
- Excessive tension shortens the life of belts and bearings.
- During the first day of operation, check the belt tension frequently. After that, make adjustments as needed.
- Sheave misalignment is often caused either by a) The engine drive shaft is not parallel with the blade shaft, or b) the pulleys are not positioned properly on the shafts.
- Use a steel straight edge to check alignment.
