The Chelsea 442 Series Power Take-Off Assembly, part number 442GQAHX-A3XK or 442GQAHXA3XK, is a 6-bolt transmission-mount PTO built around an air shift actuator and a 0.391:1 gear ratio. Output is a 1-1/4" round standard shaft, and the mounting configuration uses standard mount hardware with metric studs. The unit runs without a pressure lube system (dry-sump, no external lube line required). The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series and contribute to its reputation in light-to-medium duty vocational applications such as tow trucks, dump trucks, and service trucks. Cross-references for this part include 1450-442GQAHXA3XK, CHL442GQAHXA3XK, S-10644, TG6BU6808A1KX, WA20-06-5334. Call us to confirm proper fit for your transmission and application.
The Chelsea 442 Series is designed to work with virtually all existing 6-bolt transmission applications. Typical vocational uses for this series include tow trucks, dump trucks, service trucks, and small aerial trucks. The 442 Series owner's manual and parts list (HY25-2442-M1_US) are available through Parker Chelsea for service and installation reference.
