The Chelsea 442 Series Power Take-Off, part number 442XQAHX-W3XK or 442XQAHXW3XK, is a direct-mount, two-gear, 6-bolt PTO built for light-to-medium duty vocational truck applications. This unit runs an air shift actuator, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting uses standard 6-bolt geometry with metric studs. The no-pressure-lube (dry sump) lubrication design simplifies installation on compatible transmissions. The cast iron housing and tapered cone output shaft bearings are characteristic of the 442 Series, which covers applications including dump trucks, tow trucks, and service trucks. Cross-references include SD701, WA20-06-5008, and WA6SE01X-W1RA. Call us to confirm proper fit for your transmission and application.
