The Chelsea 489XLAHX-A5XK or 489XLAHXA5XK is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating an extra potential leak path. Shift is air shift, with an electric-over-air option available in the series. The 489 Series delivers up to 48 HP at 1000 RPM, and intermittent torque for the 489 Series is rated at 201-300 lb-ft. Internal components are common to the Chelsea 442 Series, and the kit-style design simplifies field service. Call us to confirm proper fit for your application.
The 489 Series is suited for aerial, vocational, municipal, and other mobile equipment applications including utility trucks, snow and ice removal, fire and rescue, and dump truck and trailer service.
