The Chelsea 489 Series Power Take-Off Assembly, part number 489GFAHX-P3RA or 489GFAHXP3RA, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings. Its one-piece cast iron housing bolts directly to the transmission face, eliminating the adapter plate and reducing potential leak paths. Output power ranges from 46 to 55 HP (31 to 40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque capacity for the 489 Series is 201 to 300 lb-ft (301 to 400 Nm); check application pages for your specific rating. Compatible transmissions include Eaton Fuller, Mack, Tremec, and others with an 8-bolt aperture. The output shaft is a 1-1/4" round with key, and the "P" suffix confirms pressure lube. Call us to confirm fit for your specific transmission and application.
