The Chelsea 489 Series Power Take-Off Assembly, part number 489ZLDAX-P5XK or 489ZLDAXP5XK, mounts directly to an 8-bolt transmission opening with a one-piece cast iron housing that eliminates the need for an adapter plate and reduces potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft (301-400 Nm) and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Shift is wire/cable mechanical. The 1-1/4" round output shaft is available with or without a keyway. This unit fits manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. Internal parts are common to the Chelsea 442 Series, and tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your specific transmission and application.

The Chelsea 489 Series shares internal components with the proven 442 Series, giving technicians a familiar service experience. The integral 8-bolt cast iron housing delivers 442 Series torque capacity (250 lb-ft) in a design that bolts straight to the transmission face. Tapered bearings replace needle bearings for improved load-bearing capability under demanding vocational cycles. Applications include utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. Part number 489ZLDAX-P5XK is also referenced as SP489ZLDAX-P5XK in some distributor catalogs. The 489 Series supports twenty-seven output configurations and eleven internal speed ratios across the full model range.
