BELT MEASURING INSTRUCTIONS

KEY

A: 1/2IN

B: 5/8IN

3L: 3/8IN

4L: 1/2IN

5L: 5/8IN

Note: If you’re in-between sizes, minor pulley adjustments may

be necessary. With this in mind, we recommend sizing down with

increments less than 0.5in and sizing up when 0.5in or greater.

Place the other end of the belt in the bottom guide and

stretch the belt as much as you can by pulling downward.

Place your belt in the upper guide.

Determine the belt width using the markings on the side

of the lower guide. (This example is an “A” Belt)

Determine the length by rst locating the markings that

correspond with the width, then on the left side, in-line

with that marking, you’ll see the fractional belt number.

The left size of the ruler will tell you the belt number and

the right side will tell you the belt length. (A63K / 4L650)

Locate the Sunbelt belt of that size in the display.
