The Chelsea 442 Series Power Take-Off Assembly, part number 442ZWFNX-A3RA or 442ZWFNXA3RA, is a 6-bolt mount PTO designed for a wide range of light-to-medium duty vocational truck applications. This unit operates at a 0.391:1 gear ratio and uses air shift actuation for precise, reliable engagement. The output is a 1-1/4" round standard shaft, and the standard mount uses metric studs for proper installation. The cast iron housing and tapered cone bearings on the output shaft provide extended service life, while the 360-degree rotatable output flange aids routing and clearance. No pressure lube is required. Typical applications include dump trucks, service trucks, tow trucks, and aerial units. Call us to confirm proper fit for your transmission.
