The Chelsea 489 Series Power Take-Off, part number 489XSITX-A4XK or 489XSITXA4XK, is an air shift PTO designed for 8-bolt manual transmission openings including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The integral one-piece cast iron housing bolts directly to the transmission's 8-bolt aperture, eliminating the adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range, with air shift actuation on this unit. Output is through an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
