The Chelsea 489 Series Power Take-Off Assembly, part number 489GSAHX-V5XK or 489GSAHXV5XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The integral one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path at that junction. Output shaft is a 1-1/4" round with keyway. Shift is wire/cable mechanical. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); for continuous-duty applications, de-rate by 30% and verify against the Chelsea application pages for your specific setup. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, making service components straightforward to source. Call us to confirm proper fit for your transmission and application.
