The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-A3XY or 489XRAHXA3XY, mounts directly to an 8-bolt transmission opening using a one-piece cast iron housing that eliminates the adapter plate and reduces potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft is available with or without a keyway, and the series supports 27 output options including a 360-degree rotatable flange with a greaseable shaft. Shaft power ratings are 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque capacity for the 489 Series is 201-300 lb-ft. Compatible transmissions include Eaton Fuller, Mack, and Tremec manual gearboxes with an 8-bolt PTO aperture. Call us to confirm proper fit for your application.
