The Chelsea 489ZFDAX-A5RE is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, engineered to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts straight to the 8-bolt transmission opening, eliminating a common leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft output power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Shift type is wire/cable mechanical. The output shaft is a 1-1/4 inch round shaft with key. Internal parts are common to the Chelsea 442 Series, and the unit features tapered bearings for strong load-carrying capability. Available from Pro Gear and Transmission.
