The Chelsea 442XSJWX-S5XK or 442XSJWXS5XK is a 442 Series Power Take-Off engineered for 6-bolt transmission applications. The 442 Series uses a cast iron housing and tapered cone bearings on the output shaft, giving it a strong torque rating and long service life suited to light-to-medium duty vocational work. The series supports wire/cable or mechanical shift and a round output shaft with a 1-1/4" key. With eleven internal speed ratios and thirty-six output options, including a 360° rotatable flange, the 442 Series covers a wide range of truck configurations. Common applications include dump trucks, service trucks, tow trucks, and aerial units. Call us to confirm proper fit for your specific transmission and application.
With eleven internal speed ratios, thirty-six output options, and ten shift configurations, the 442 Series offers flexibility that covers a broad range of hydraulic and mechanical output demands. The 360° rotatable flange is particularly useful in tight engine compartments where output direction is constrained.
Typical applications include snow and ice trucks, service trucks, dump trucks, and towing and recovery vehicles. Not sure this is the right PTO for your truck or transmission? Give us a call and we can help you verify the fit.
