Installation Notes

V-belt replacement is typically performed by HVAC technicians or mechanical maintenance professionals. Always de-energize and lock out the equipment before removing or installing belts. Adjust sheave spacing to allow belt installation without forcing or prying, then tension the belt according to the equipment manufacturer specifications. Inspect sheave grooves for wear before installing a new belt to avoid premature failure.
