The Chelsea 489 Series Power Take-Off Assembly, part number 489XHITX-A3RB or 489XHITXA3RB, mounts directly to the 8-bolt transmission opening with a one-piece cast iron housing that eliminates the adapter plate and reduces potential leak paths. The 489 Series is rated for intermittent torque in the 201-300 lb-ft range and delivers the same torque capacity as the Chelsea 442 Series. Output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. The series fits most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. Tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your specific transmission.
The Chelsea 489 Series is suited for vocational and municipal equipment including utility trucks, dump trucks, snow and ice removal vehicles, and fire and rescue apparatus. The one-piece cast iron housing integrates directly with the 8-bolt transmission mount, removing the need for an adapter plate and the additional leak path it would introduce. Internal components are shared with the Chelsea 442 Series, making parts sourcing and bench service straightforward for shops already familiar with that platform. Multiple speed ratios and shift configurations are available across the 489 Series lineup. Consult the 489 Series Parts List (HY25-2442-M1_US) or the Chelsea Service Manual (HY25-6489-M1/US) for detailed assembly and service information.
