Below is a list of Hydraulic Clutch Pump manufacturers from Franklin, Indiana. Hydraulic clutch pumps are systems in which a clutch assembly is accompanied by a pump that allows the user to apply the required pressure to either engage or disengage the clutch system. Hydraulic clutches, like all clutches, are designed to either connect two shafts, locking them together to spin at the same speed, or to decouple the shafts, allowing them to spin at different speeds, as is necessary to shift gears or decelerate.
