The Chelsea 442ZWBZX-M4RC is a 442 Series Power Take-Off built for 6-bolt transmission applications. The series features a cast iron housing with tapered cone bearings on the output shaft, delivering an intermittent torque range of 201-300 lb-ft and output power of 46-55 HP. The round output shaft uses a 1-1/4" key configuration, and the wire/cable mechanical shift keeps the unit low-profile. Rotatable output flanges allow clearance adjustment to suit the installation. Typical applications include tow trucks, service trucks, dump trucks, and small aerial trucks. Pro Gear and Transmission carries this genuine Chelsea unit for 6-bolt drivetrain setups.
