The Chelsea 489DLMCX-56XY is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing covers an intermittent torque range of 201-300 lb-ft and supports a wire/cable mechanical shift configuration. Output is via a 1-1/4" round keyed shaft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 Series uses tapered bearings in place of needle bearings for increased load-bearing capacity, and internal parts are common to the Chelsea 442 Series. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Available from Pro Gear and Transmission.
