Part Description
Standard clockwise rotation, Idler gear shaft (OEM 25791-36)
Text excerpt from the catalog:
S&S re-designed the idler-, circuit breaker-, and circuit breaker drive gears to have a quality replacement available that suits today's demands by adopting modern technology and metallurgic knowledge. Gears have a modified gear profile that provides a higher contact ratio for quieter operation and reduced gear lash for more accurate and consistent ignition timing. Both the idle gear and circuit breaker drive gear have widened hubs with two, factory installed and sized bearing bushings per gear for stable operation. This design eases installation too, as there is no need to use spacers as with the OEM gears. The circuit breaker drive gear has been narrowed to simplify installation of high lift cams, and are available in two versions. The standard version turns the timer in the stock clockwise rotation and is meant as a direct replacement for or to supersede stock gears to be used with stock style timers The counterclockwise or reverse rotation version enables the builder to use some aftermarket distributors with certain electronic ignition systems. All gears are precision manufactured to tight tolerances and critical areas are finish ground after a heat treatment to eliminate distortion and reduce wear. S&S timing gears are also available as a complete kit for that perfect overhaul.
