Sheave Gauges

Sheave gauges are a great tool that surprisingly people don’t always know about. They have been around for quite a few years, and are just as useful as ever. They are small plastic cutouts that you place inside a sheave groove to see if there is enough wear that the sheave should be replaced. If more than 1/32” of wear can be seen between the gauge and the sidewall of the groove, the sheave should be replaced. Worn sheaves are a big contributor to premature belt failure.

With the set, you get a gauge for multiple sections, and each gauge has 3 different angles for measuring a wide range of diameters within that belt section. These can also be used to help identify what type of belt a particular sheave is designed for if it is not significantly worn down. There is also a belt gauge in the set that can be used to help identify the particular belt section as well.
