The Chelsea 489 Series Power Take-Off, part number 489XCAHX-A5RF or 489XCAHXA5RF, is an air-shift PTO built around an 8-bolt mounting pattern that fits most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the 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 tapered bearings for greater load capacity than needle-bearing designs. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your application.
