Chelsea 442 Series power take-off assembly, part number 442ZQFNX-A5XK or 442ZQFNXA5XK, is a 6-bolt mount PTO engineered for light-to-medium duty vocational truck applications. This unit runs an air shift actuator and a 0.391:1 gear ratio, putting output speed above input speed for hydraulic pump and auxiliary equipment drives. The 1-1/4" round standard output shaft accepts a keyed connection, and the standard mount uses metric studs for direct bolt-up to compatible transmissions. No pressure lube is required; the output shafts are greaseable for routine field maintenance. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series platform. Call us to confirm proper fit for your transmission application.
