The Chelsea 442 Series Power Take-Off Assembly, part number 442ZSDAX-A3RF or 442ZSDAXA3RF, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including tow trucks, dump trucks, and service trucks. This unit runs air shift actuation and a rotatable SAE B 2-bolt flange output with a 1" 15-tooth SAE BB shaft. Mounting uses a deep mount. The no-pressure-lube (dry sump) configuration keeps the design compact and low-maintenance.
