The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-A3GY or 489XFAHXA3GY, mounts directly to an 8-bolt transmission opening using a one-piece cast iron housing that eliminates the need for an adapter plate, reducing potential leak paths. This unit uses a wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. The 489 Series fits most manual transmissions with an 8-bolt PTO aperture, including Eaton/Fuller, Mack, and Tremec. Internally, the 489 shares common parts with the Chelsea 442 Series and uses tapered bearings rather than needle bearings for greater load capacity. Call us to confirm proper fit for your specific transmission.
The Chelsea 489 Series is suited for utility trucks, dump truck and trailer applications, snow and ice removal, fire and rescue, and aerial and vocational equipment. The 489 Series offers eleven internal speed ratios and twenty-seven output options, including a 360-degree rotatable flange. For parts and service information, refer to the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
