The Chelsea 489XCAHX-A3GQ or 489XCAHXA3GQ is a 489 Series power take-off assembly built for 8-bolt manual transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. The one-piece cast iron housing bolts directly to the 8-bolt aperture, eliminating the need for an adapter plate and reducing potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key option) delivers up to 48 HP at 1,000 RPM and 24 HP at 500 RPM. Intermittent torque capacity for the 489 Series is 201-300 lb-ft. Internal components are common to the Chelsea 442 Series, so replacement parts are straightforward to source. Call us to confirm proper fit for your specific transmission.
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 operations. The 489 Series parts list (HY25-2442-M1_US) and service manual (HY25-6489-M1/US) are available through Parker Chelsea's product support section for detailed assembly and maintenance information.
