The Chelsea 442 Series Power Take-Off Assembly, part number 442KSJKX-A5GH or 442KSJKXA5GH, is a 6-bolt mount PTO with a 0.391:1 gear ratio and air shift operation. It mounts using the standard configuration with metric studs and delivers power through a 1-1/4" round standard output shaft. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which targets light-to-medium duty vocational applications including dump trucks, service trucks, and tow trucks. The no-pressure lube configuration (X designation) suits installations where a dedicated pressure lube circuit is not available. Call us to confirm proper fit for your transmission application.
