The Chelsea 442 Series Power Take-Off, part number 442XSJKX-A5XD or 442XSJKXA5XD, is a 6-bolt air-shift PTO built around a cast iron housing with tapered cone bearings on the output shaft. This unit carries a 0.391:1 gear ratio, mounts via standard metric studs, and delivers power through a 1-1/4" round standard output shaft. The no-pressure-lube (dry-sump) lubrication design keeps installation straightforward. A low-profile shift cover aids fitment in tight cab or chassis environments. The 442 Series suits light-to-medium duty vocational applications including dump trucks, tow trucks, service trucks, and small aerial units.
