The Chelsea 442 Series Power Take-Off Assembly, part number 442ZSDAX-A5XD or 442ZSDAXA5XD, is a 6-bolt mounting PTO engineered for light-to-medium duty vocational truck applications including dump trucks, service trucks, and tow trucks. This unit runs a 0.391:1 gear ratio with air shift actuation and delivers power through a 1-1/4" round standard output shaft. The standard mount uses metric studs, and lubrication is splash-type with no pressure lube circuit required. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which offers a series-rated intermittent torque range of 201-300 lb-ft.
