The Chelsea 442 Series Power Take-Off Assembly, part number 442ZQAHX-H3XD or 442ZQAHXH3XD, is a 6-bolt, standard-mount unit engineered for light-to-medium duty vocational truck applications including tow trucks, dump trucks, and service trucks. This assembly runs an air shift mechanism, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The unit operates without pressure lubrication (no pressure lube configuration). The cast iron housing and tapered cone output shaft bearings are characteristic of the Chelsea 442 Series, which carries a series intermittent torque rating of up to 300 lb-ft. The output shaft is greaseable, and the output flange is rotatable for clearance flexibility. Call us to confirm proper fit for your specific transmission application.
