The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-S3RB or 489XLAHXS3RB, mounts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, Tremec, and other manual transmissions. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and cutting installation time. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key option available) delivers up to 48 HP at 1,000 RPM, with an intermittent torque rating in the 201-300 lb-ft range for this series. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series is suited for utility trucks, dump truck and trailer applications, snow and ice removal, fire and rescue, and aerial equipment. The 489 Series shares internal components with the Chelsea 442 Series, so shops already familiar with the 442 can service this unit with common tooling and parts. Eleven internal speed ratios and multiple shift options are available across the 489 Series lineup. For detailed parts and service information, refer to the 489 Series Parts List (Parker document HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
