The Chelsea 489XFAHX-W3AF or 489XFAHXW3AF is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing mounts directly to the transmission opening without an adapter plate, eliminating that potential leak path. Shift is wire/cable mechanical. 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 for this series, confirm actual torque for your specific application. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
The Chelsea 489 Series is designed for aerial, vocational, municipal, and other mobile equipment applications including utility trucks, snow and ice removal, fire and rescue, and dump trucks and trailers. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift configurations are offered within the series. The kit-style design simplifies field service. For parts reference, see the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US) available from Parker Chelsea.
