The Chelsea 489 Series Power Take-Off Assembly, part number 489XCAHX-H5XD or 489XCAHXH5XD, mounts directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec units using a one-piece cast iron housing that eliminates the need for an adapter plate. The wire/cable mechanical shift type and 1-1/4" round output shaft with key deliver intermittent torque in the 201-300 lb-ft range, with the series rated at 250 lb-ft. Shaft power reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, and the kit-style design simplifies service work. Call Pro Gear and Transmission to confirm the correct configuration for your application.
