SAE J960_200804

The purpose of this SAE Recommended Practice is to provide guides toward standard conditions for operating marine hydraulic transmissions where push-pull cable control is applicable. For control cable information see SAE J917. a Provide suitable detents at forward, neutral, and reverse positions. Approximately 22 N (5 lb) of cable force are required to move the engine clutch lever out of the detent positions. b Provide an engine clutch lever with a 6.35 mm (1/4 in) diameter hole at a radius to provide 70 mm (2-3/4 in) linear travel from forward to reverse, with neutral at the center. The engine clutch lever (at 6.35 mm [1/4 in] diameter hole) to have 6.35 mm (1/4 in) maximum thickness. Common cable terminals used are ball joints, clevises, and pivots. c Provide clear cable path to engine clutch lever. d Provide choice of cable paths from different angles. This can be done by providing a sector type of lever with a series of holes equidistant from the centerline of the shaft. It can also be done by having the engine clutch lever repositionable on the engine clutch control shaft. e Provide bracket support near the engine clutch control shaft. This can be a hub, bolt holes, bolt, or other means for use for attaching a cable anchor bracket. A bolt pattern concentric with the engine clutch control shaft is desirable.
