The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-V3GF or 489XRAHXV3GF, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec models. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path while delivering the same intermittent torque capacity as the Chelsea 442 Series. Output shaft is a 1-1/4" round shaft with key. Shift is wire/cable mechanical. Output power ranges from 46 to 55 HP (31 to 40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
