13. Pitch Gauge Measuring Tool for Volta Positive Drive Belts
Volta Positive drive belts need to be welded endlessly while maintaining a correct pitch tolerance between the teeth
closest to the weld. A small tool has been developed to ensure this.
The Pitch Gauge Measuring Tool is not included in the FBW Welding kit.
This tool can be purchased as a separate unit - Cat.No. - 81307570.
Positive Drive Pitch Gauge Tool Instructions

WELD
PITCH IS TOO SMALL
Replacing the belt type gauge
blocks:
Remove the four bolts using the
supplied 3mm Allen key and
reconnect upper and lower to the
desired belt type gauge block.
Calibrating the gauge:
1. Unfasten the knob and place
the gauge blocks on two adjacent
belt teeth. (Not the teeth adjacent
to the weld).
2. Push the gauge base to the
position so it sits firmly to the
outer side of the gage block. (The
gauge blocks should sit firmly on
both teeth). Tighten the knob to
lock the gauge in place.
3. Checking the weld:
Place the gauge on the two closest teeth on both sides of the weld.
The gauge should sit firmly on both teeth. If there is a small gap as seen in picture 3a the pitch is within the allowed
tolerance. In case the gauge doesn’t sits firmly on the teeth refer to pictures 3b and 3c.
