  • 500 Series Engagement Chart

    • The following engagement chart is based on static rotation testing only. In actual selection of components, the weight of the arm relative to the horsepower being transmitted should also be considered.

      NOTES: Although different combinations of weights and springs might result in the same engagement RPM, the heavier weights and stronger springs cause quicker upshifts (lower RPM) and slower backshifts (lower RPM).
