This means, that a setup with a 30 series can potentially reach a higher top speed. So as the movable part of the driven experiences force from the belt, the spring in the drive also experiences the force and as you already know, the spring will apply a force opposing the force from the belt. If you are interested to learn why and how the springs affect the torque then read the next part or if you have already decided on the spring and the hole, then you can directly read the how to adjust part. Heres a diagram explaining how to install them properly. This Stamp does not determine the series type, ignore it completely. A damaged belt is a symptom of another problem.

Ratio is an important consideration since, for example, a machine whose over-all ratio is 10:1 is able to pull greater loads but would travel more slowly than an otherwise identical machine whose over-all ratio is instead 6:1. Step 5: Fix the other side of the spring onto the hole of the movable part of the driven (there is only 1 hole in the movable part). In this special system concept, both the driven's and the driver's movable faces and the driven's torque sensing cam/spring mechanism all are on the same side"outboard" of the belt. This Stamp does not determine the series type, ignore it completely. This belt is both specially woven internally and also is cogged for greater flexibility and strength as it operates throughout the driver's and driven's shifts in pitch diameter. Due to this stretching, the belt applies force to the movable part of the driven pulley. Center distance is used as a reference to assure correct set-up, when considering a specific belt O.C.
