Fan Drive Belt

Operating The Measuring Instrument





1. Prepare measuring instrument for testing
- Lower pointer into measuring instrument

2. Pick up measuring instrument
- Grasp rubber strap between thumb and index finger.

3. Position measuring instrument
- Position measuring instrument in center between pulleys on the drive belt.
- The lateral stop of the instrument must rest on the side of the V-belt.

4. Measure belt tension
- Press push-button to apply uniform pressure in perpendicular direction on top of V-belt until the detent spring can be heard (or felt) to disengage. - After the detent spring has disengaged, the measuring instrument or the push-button, respectively, must not be pressed anymore as the reading will otherwise be incorrect.

5. Read off measurement
- Lift measuring instrument carefully off the V-belt.

CAUTION:
- Do not push against instrument when lifting off the instrument as sudden impacts may alter the position of the pointer and may give a faulty reading.
- Read off measurement (tensioning value) at the point of intersection of the pointer with the upper scale (KG scale).
