The Chelsea 489 Series Power Take-Off Assembly, part number 489GFITX-V3RA or 489GFITXV3RA, is an 8-bolt PTO designed to mount directly to the transmission opening without an adapter plate, reducing potential leak paths and installation time. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series (201-300 lb-ft / 301-400 Nm). Shift is air shift. Output is a rotatable SAE B 2-bolt flange with a 7/8" 13-tooth SAE B shaft. Output power reaches 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Fits manual transmissions including Eaton/Fuller, Volvo/Mack, and others. Internal parts share commonality with the Chelsea 442 Series. Call us to confirm proper fit for your application.
