The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-A3GY or 489XHAHXA3GY, mounts directly to an 8-bolt transmission opening without an adapter plate, eliminating a potential leak path. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series, rated at 201-300 lb-ft (301-400 Nm). Shift is via wire/cable mechanical actuation. Output is through a 1-1/4" round shaft (with key option), and shaft power is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. The 489 Series fits most manual transmissions including Eaton/Fuller, Mack, and Tremec applications with an 8-bolt PTO aperture. Call us to confirm proper fit for your transmission.
