The Chelsea 489 Series Power Take-Off Assembly, part number 489XUAHX-W3GF or 489XUAHXW3GF, mounts directly to an 8-bolt transmission opening on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions - no adapter plate required. The one-piece cast iron housing eliminates a common leak path and delivers the same 250 lb-ft intermittent torque rating as the Chelsea 442 Series. Shift type is wire/cable mechanical. The 1-1/4" round output shaft (with key) is supported by tapered bearings rather than needle bearings for greater load capacity. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM, with a continuous rating achieved by de-rating 30% from the intermittent figure (confirm actual values on Chelsea's application pages). Internal parts are common to the 442 Series, making service straightforward. Call us to confirm proper fit for your transmission and application.
