To find the proper belt for your application, you should know the following:

  • The make and model of the engine

  • The style of pulleys (1/2 pitch, 8mm, 14mm, etc...)

  • The total tooth count of both Upper and lower pulleys

  • The center to center distance between the upper and lower blower pulley

Locate your engine and belt style in the chart below. The chart will find a total teeth range for a specific belt length. If you cannot decide which belt will work for your application, we suggest calling our tech Department.

Belt Length Chart
* Chart #'s represent the Maximum tooth count of the top and bottom sprockets.
* An allowance of 2-3 teeth less should be used to allow removal of the belt and have the slack taken up by the idler.
