Gates Universal Transmission Spring Tension Tester

The Universal Transmissions Spring Tension Tester is a gauge for the professionally-equipped workshop to measure and check the tension of Gates belts. It works with an integrated ruler, a scale with pointer and a measuring stone that is pretensioned by a spring and uses the deflection of the belt as a measure of the current belt tension. A correctly tensioned belt is essential for the belt drive to function optimally, so that it neither skips nor runs too heavily, thus avoiding increased wear. Common tension adjustment systems include inclined or vertical dropouts, horizontally sliding dropouts (not recommended by Gates) and eccentric bottom brackets.
Specifications:Function:Measures belt tensionType:gauge, special toolCompatibility:Gates Carbon Drive SystemInstructions:Place the Spring Tension Tester over the two sprockets on the belt. This changes the position of the finger and shifts the pointer on the scale.Use the pointer to read the current belt tension: red means the belt tension is too low, yellow means it’s too high, green means the belt tension is on an optimal level.Repeat the measurement at different crank positions. Before doing so, always return the pointer to its starting position below the red area.
