The Chelsea 442 Series Power Take-Off Assembly, part number 442ZFITX-A3XD or 442ZFITXA3XD, is a 6-bolt mount PTO built for light-to-medium duty vocational truck applications. This unit runs a 0.391:1 gear ratio and engages via air shift, making it a straightforward fit on transmissions where pneumatic control is already present. The output is a 1-1/4" round standard shaft with no pressure lube requirement. Mounting uses standard metric studs. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, giving it a long service life in demanding cycles. Typical applications include tow trucks, dump trucks, service trucks, and small aerial units. Call us to confirm proper fit for your transmission.
