Eliminate Spline Fretting and Extend the Life of your PTO and Pump Shaft - Use PTOs with Wet Spline Design

Premature spline fretting is a common issue stemming from the torsional vibrations present in modern high torque, low speed motors. As engine speed decreases, the vibrations affecting the PTO and pump splines intensify, particularly when the PTO is disengaged, and there is minimal load on the connecting shafts.

Wet Spline is a specialized lubrication system that provides continuous flow of fresh, clean oil to the PTO and output shafts. This lubrication process operates throughout all stages of operation, including when the PTO is disengaged. By ensuring a steady flow of fresh oil to the PTO and output shafts, Wet Spline effectively combats premature fretting on the spline shaft, enhancing the durability and reliability of the hydraulic system while cutting down on maintenance expenses and downtime. Wet Spline guarantees optimal lubrication and protection, even in the face of extreme conditions.

With Wet Spline technology, maintenance downtime is significantly reduced, and pump shaft lifespan sees a remarkable increase of 7-10 times. This proven technology has been successfully utilized in military applications and various commercial vehicles, such as refuse trucks, yard spotters, material handling equipment, aerial vehicles, and more.

Before the introduction of Chelsea's Wet Spline innovation, pump shaft lubrication was a manual chore integrated into routine maintenance schedules. Every 2-3 months, pumps had to be removed from the PTO mating shafts, meticulously cleaned, and freshly greased, before reinstalling the pump and retorquing the bolts to specifications. Thanks to Chelsea's Wet Spline solution, this time-consuming task is eliminated, ensuring increased uptime and keeping your fleet on the move.
