The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-V3RA or 489XFAHXV3RA, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and cutting installation time. Shift type is wire/cable mechanical. The 1-1/4" round output shaft (with key option) delivers up to 48 HP at 1,000 RPM, with an intermittent torque rating in the 201-300 lb-ft range for this series. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series is suited for aerial, vocational, and municipal equipment applications including utility trucks, snow and ice removal, fire and rescue, and dump truck and trailer use. The series offers eleven internal speed ratios and twenty-seven output options, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline wear and corrosion. Strong tapered bearings replace needle bearings for improved load-bearing capability. For service documentation, reference Chelsea parts list HY25-2442-M1_US and service manual HY25-6489-M1/US.
