Checking V-Belt

CHECK CONDITION OF V-BELT
Check for:
- Splits in base material (cracks, core fractures, cross-section fractures).
- Separation of layers (top layer, tensile cords) bursting on base material.
- Fraying of cords.
- Flank wear (material flaking, frayed flanks, hardening of flanks [glassy surface], surface cracks)
- Traces of oil or grease.

Replace the V-belt if faults are found.

CHECK V-BELT TENSION
Check V-belt tension by applying strong thumb pressure to the area of the belt between the two pulleys that are furthest apart.

^ Deflection for used V-belt: approx. 5 mm (0.197 inch).
