Description
The Chelsea 442 Series Power Take-Off 442ZRFNX-A3XD or 442ZRFNXA3XD is a 6-bolt mount PTO built around a cast iron housing with tapered cone bearings on the output shaft. This unit runs a 0.391:1 gear ratio and engages via air shift, making it a direct-acting, cab-controlled option for vocational trucks. The output is a 1-1/4″ round standard shaft, and mounting uses the standard configuration with metric studs. No pressure lube is required, simplifying installation in applications without a pressurized lube circuit. The 442 Series is suited for tow trucks, dump trucks, service trucks, and light aerial units. Call us to confirm proper fit for your transmission application.
