The Chelsea 489 Series Power Take-Off assembly, part number 489ZWDAX-A5AF or 489ZWDAXA5AF, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate found on some installations, reducing potential leak paths. Shift actuation is wire/cable mechanical. The 1-1/4" round output shaft with key delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM, with an intermittent torque rating in the 250 lb-ft range (verify actual rating on the Chelsea application pages for your specific installation). Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series is suited for aerial, vocational and municipal equipment, utility trucks, snow and ice removal, fire and rescue, and dump truck applications. The kit-style design simplifies service, and internal parts are interchangeable with the Chelsea 442 Series. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline wear and corrosion. Eleven internal speed ratios and shift configurations are offered across the series. For full parts and service documentation, refer to Chelsea 489 Series Parts List HY25-2442-M1_US and Service Manual HY25-6489-M1/US.
