The Chelsea 442 Series Power Take-Off Assembly, part number 442ZHDAX-P3AF or 442ZHDAXP3AF, is a 6-bolt mount PTO built for light-to-medium duty vocational applications. This unit uses 12V electric/air shift actuation and delivers power through an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. Mounting uses the deep mount. The housing requires no pressure lube. Tapered cone bearings on the output shaft work alongside a cast iron housing to support the 442 Series intermittent torque range of 201-300 lb-ft. Typical applications in this series include dump trucks, tow trucks, service trucks, and aerial units. Call us to confirm proper fit for your transmission application.
