The Chelsea 489 Series Power Take-Off, part number 489XQAHX-P5RE or 489XQAHXP5RE, is a mechanical-shift PTO designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec. The integral 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. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, backed by strong tapered bearings for greater load capacity compared to needle-bearing designs. The round output shaft measures 1-1/4" with a key drive. Call us to confirm proper fit for your specific transmission and application.
