The Chelsea 489QHITX-V3RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The integral one-piece cast iron housing eliminates the adapter plate leak path common on other PTO designs. The 489 Series delivers intermittent torque of 201-300 lb-ft and output power of 46-55 HP, with a 1-1/4" round keyed output shaft. Shift type is wire/cable mechanical. Tapered bearings replace needle bearings for greater load-bearing capability. Pro Gear and Transmission carries this genuine Chelsea unit for vocational, municipal, and utility truck applications.
