Always use a belt tension gauge that indicates static tension, such as the Gates Krikit® Tension Gauge, (Part No. 91107 for Standard, Part No. 91132 for Micro-V) to determine proper tension from the Installation Chart. Tension ranges above are for drives requiring single belts. If multiple belts are needed for a drive, divide tension by number of belts to give per belt tension to be measured.

  • Step 2: Run belt for five minutes.
  • Step 3: If belt tension drops below Suggested Tension range, retighten belt to Installation Tension.

This will allow the belt to seat-in and run at Suggested Tension after it has operated under normal driving conditions.
