How to Measure a Belt using the 75-910 Belt Measurer
1. Define type of belt :
� 3L = 3/8" or 9.5 mm
� 4L = 1/2" or 12.7 mm
� 5L = 5/8" or 15.9 mm
2. Fit the belt over the blue plastic split pulley and pull the bottom half down tight.
3. If you are measuring an industrial belt (bulgy top) look at the left-hand slot in the half pulley.
The size (section) of the belt is indicated by the intersection of the belt top with one of the white blocks, either A or B.
If you have an FHP belt (flat top), the same procedure applies to the right-hand slot. The belt in the photo is a 4L belt (the section).
4. Now that you know the belt�s profile (section), look at the window below the split pulley and find the section number for your belt (3L, 4L, 5L, A or B) printed in white on the left side of the window. The number opposite or closest is the length in inches of the belt you are measuring.
