The Chelsea 489GQAHP-A5GB or 489GQAHPA5GB is a 489 Series Power Take-Off Assembly designed for manual transmissions with an 8-bolt PTO mounting opening, including Eaton Fuller, Volvo/Mack, and other compatible units. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, which eliminates a potential leak path versus two-piece configurations. This unit uses a wire/cable mechanical shift and delivers an intermittent torque capacity of 250 lb-ft (339 Nm) with output power ranging from 46 to 55 HP (31 to 40 kW). Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. The 1-1/4" round output shaft with key suits a wide range of pump and accessory drive applications. Tapered output bearings replace needle bearings for improved load handling. Call us to confirm proper fit for your application.
