442KXBQX-W4XD Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off, part number 442KXBQX-W4XD or 442KXBQXW4XD, is a 6-bolt, air-shift PTO built for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. The 0.391:1 gear ratio drives a 1-1/4" round standard output shaft (XD output option). Mounting uses the standard configuration with metric studs. The unit runs without pressure lube (dry-sump lubrication). Cast iron housing and tapered cone bearings on the output shaft support the 442 Series intermittent torque range of 201-300 lb-ft. A 360-degree rotatable output flange and greaseable output shaft are standard to this series. Call us to confirm proper fit for your transmission application.
