The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-W3RA or 489XSAHXW3RA, mounts directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate, reducing both installation time and potential leak paths. Shift is wire/cable mechanical; this unit also supports an electric-over-air shift option. The 1-1/4" round output shaft (with key) delivers up to 48 HP at 1,000 RPM, with an intermittent torque rating in the 201-300 lb-ft range. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts share commonality with the Chelsea 442 Series, simplifying parts sourcing. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series fits a wide range of vocational applications including utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The kit-style PTO design makes field service straightforward, and with eleven internal speed ratios available across the 489 Series, this platform supports varied hydraulic and mechanical accessory requirements. Internal parts commonality with the Chelsea 442 Series means parts counters already stocked for the 442 can cover many 489 service needs.
