Carlisle Sheave Gauges accurately check pulley grooves for wear. A worn pulley can cause belt damage, slippage and excessive downtime.
A new v-belt should never be installed without proper inspection of the condition of the pulley or sheave. Sheave condition and alignment are critical for v-belt performance and lifetime. Particular attention should be given to wobbling sheaves, a shiny groove bottom and worn groove sidewalls.
Use the sheave gauge to accurately check grooves for wear. A flashlight held behind the template, when placed in the groove, will help you observe the amount of wear. Wear should not exceed 1/32″ for individual v-belt drives and 1/64″ for banded belt drives.
