1. Add the large and small pulley diameters together.
10 + 2 = 12
2. Multiply the total
amount by 1.6
(Half of 3.14 (pi) of the sum of
the two pulleys)
12 x 1.6 = 19.2
3. Add twice
the distance between the two shafts.
24 x 2 = 48
48 + 19.2 = 67.2
The total will be the
approximate belt length.
67" belt
