442XXBSX-A3XD Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off, part number 442XXBSX-A3XD or 442XXBSXA3XD, is a 6-bolt mount PTO built around a cast iron housing and tapered cone output shaft bearings. This unit runs a 0.391:1 gear ratio and shifts via air, with a standard mount using metric studs. The 1-1/4" round standard output shaft (XD option) is greaseable for extended service life, and the output flange rotates 360 degrees to give you clearance flexibility during installation. No-pressure-lube design keeps the configuration simple. The 442 Series is suited for tow trucks, dump trucks, service trucks, and light-to-medium aerial applications.
