The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-P5RB or 489XRAHXP5RB, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), matching the 442 Series torque capacity. Output is a 1-1/4" round shaft with key, and shift is wire/cable mechanical. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, simplifying parts inventory. Available with pressure or no-pressure lube configurations. Call us to confirm proper fit for your specific transmission and application.
