The Chelsea 489 Series Power Take-Off Assembly, part number 489XAAHX-P3XD or 489XAAHXP3XD, mounts directly to 8-bolt manual transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions without an adapter plate, eliminating that potential leak path. The one-piece cast iron housing delivers an intermittent torque rating of 250 lb-ft (339 Nm) and output shaft power of 24 HP at 500 RPM, scaling to 48 HP at 1,000 RPM. This unit features a 1-1/4" round output shaft with key, wire/cable mechanical shift, and pressure lube ("P" suffix). Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
The Chelsea 489 Series is suited for utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump truck applications. The 489 Series electric-over-air shift option and 27 available output configurations, including Chelsea's 360-degree rotatable flange, make this a versatile PTO for vocational and municipal equipment. For service documentation, refer to the 489 Series Parts List (HY25-2442-M1_US) and Chelsea Service Manual (HY25-6489-M1/US).
