The Chelsea 489GFAHX-A5XK or 489GFAHXA5XK is a 489 Series power take-off assembly built for 8-bolt PTO mounting apertures on manual transmissions including Eaton/Fuller, Volvo/Mack, and other compatible makes. The integral 8-bolt housing eliminates the need for an adapter plate, reducing potential leak paths at the mounting face. Shift actuation is wire/cable mechanical, with an electric-over-air shift option available. The output shaft is a 1-1/4" round configuration (with key option), and the unit delivers up to 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, simplifying parts sourcing and service. Cross-references include S-10497 and WA20-08-7044. Call Pro Gear and Transmission to confirm proper fit for your transmission and application.
