489GLITX-A3RA Chelsea PTO Assembly

The Chelsea 489 Series Power Take-Off Assembly, part number 489GLITX-A3RA or 489GLITXA3RA, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path in the process. Intermittent torque capacity for the 489 Series matches the 442 Series at 250 lb-ft (339 Nm); check application pages for actual torque ratings for your installation. Output shaft is 1-1/4" round with keyway. Shift is wire/cable mechanical. Shaft power is rated at 24 HP (18 kW) at 500 RPM and 48 HP (36 kW) at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, simplifying service and parts sourcing. Call us to confirm proper fit for your transmission and application.
