Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489XWAHX-A5XD or 489XWAHXA5XD, is an 8-bolt direct-mount PTO designed for manual transmissions including Eaton Fuller, Mack, and Tremec applications. 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. This unit delivers intermittent torque in the 201-300 lb-ft range, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4″ round output shaft is available with key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, and the kit-style design simplifies servicing. Call us to confirm proper fit for your transmission and application.
