Glossary “belt width” Definition:
Distance across a belt measured at the widest point.

Glossary “belt clamping action” Definition:
As related to a continuous variable transmission, the action taking place when the V-pulley sheaves clamp the drive belt.

Glossary “belt cover” Definition:
1). Nylon cover positioned over the belts in a tire that helps to hold the tire together at high speed, and provides longer tire life. 2). A rayon, cotton, or nylon cover to protect the interior of a drive belt from the environment and absorb the wear that occurs at the belt-sheave interface. 3). Cover(s) used to protect the timing belt.

Glossary “belt dressing” Definition:
A prepared solution, generally in spray form, formulated for use on automotive V-belts to reduce or eliminate belt noise. It is not generally recommended for serpentine belts.

Glossary “belt driven cooling fan” Definition:
A rigid or flexible cooling fan is driven by a belt from the crankshaft in vehicles that have longitudinally mounted engines. Usually the belt-driven cooling fan is mounted to the front of the water pump pulley/hub.

Glossary “belt pitch” Definition:
The distance between two adjacent tooth centers as measured on the pitch line of a synchronous belt.

Glossary “belt ride dimension” Definition:
A measurement of the distance from the top of the belt to the top of the sheave groove to determine proper belt fit in the groove.

Glossary “belt tension” Definition:
The tightness of a drive belt, generally measured in ft-lb (N.m).

Glossary “belt tension gauge” Definition:
Allows you to accurately adjust accessory drive belt tension. Drive belts which are improperly adjusted can cause conditions like overheating, noise complaints and charging system concerns. Overlt-tight belts place severe loads on accessory bearing, often causing premature component failure.
