Description
The Chelsea 442 Series Power Take-Off, part number 442XWKBX-W5XD or 442XWKBXW5XD, is a 6-bolt mount PTO built around a cast iron housing with tapered cone bearings on the output shaft. This unit runs an air shift mechanism, a 0.391:1 gear ratio, and delivers power through a 1-1/4″ round standard output shaft. Mounting uses the standard configuration with metric studs, and the unit operates without a pressure lube system. The 360-degree rotatable output flange allows clearance adjustments at installation. Suited for tow trucks, dump trucks, service trucks, and light-to-medium aerial applications, the 442 Series fits virtually all existing 6-bolt transmission configurations. Call us to confirm proper fit for your specific transmission and application.
