489XUAHX-A5XD Chelsea PTO Assembly

The Chelsea 489XUAHX-A5XD or 489XUAHXA5XD is an 8-bolt power take-off assembly from the 489 Series, designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft is available with keyway. The 489 Series delivers the same intermittent torque capacity as the 442 Series at 250 lb-ft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying service. Call us to confirm proper fit for your transmission.
