How to use the V-belt tension meter
▪ The tension meter is a tool designed to check and re‑tighten the V‑belts. It is
made of two sliding pipes with a graded spring inside.
▪ Refer to Figure: Belt tensioning. Set the first O-ring at 1 mm (0.03 inch) (PIX)
on the millimetre scale or 25 inches of span, as shown in picture 3, and the
other O‑ring on position 0 on the Newton scale.
▪ Install the tension meter as shown in picture 1, in the middle, halfway between
the V‑belt contacts point of the V‑belts and the two pulleys.
▪ Push the Newton scale's black rubber down to reach a 10 mm (0.39 inch)
bending of the V‑belt as shown in pictures 2 and 4.
