Rotatable Wet Spline Pump Flanges

Chelsea has a rotatable Wet Spline option for the 277 and 278 series PTOs. The ability to index the output flange of the PTO 360 degrees provides the ability to maximize pump clearance between the transmission and frame rails where space is always at a premium. Torsional vibrations from today's diesel engines prematurely wear out the mating shafts between the PTO and pump. The Wet Spline output option helps provide extended shaft life.
