The Chelsea 442 Series Power Take-Off, part number 442XHAHX-A4XK or 442XHAHXA4XK, is a 6-bolt mount PTO built around air shift actuation. The unit uses a standard mount, and the output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. The unit runs without pressure lube (dry-sump configuration). Housing is cast iron, and the output shaft rides on tapered cone bearings for durability in light-to-medium duty service. Typical applications include tow trucks, dump trucks, service trucks, and aerial units. The 442 Series supports up to 36 output configurations and 11 internal speed ratios across the family, making it adaptable to a wide range of vocational builds.
