The Chelsea 489 Series Power Take-Off, part number 489GLAHX-A5GF or 489GLAHXA5GF, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a potential leak path. Compatible with most manual transmissions including Eaton Fuller, Mack, and Tremec. The 489 Series delivers up to 250 lb-ft torque capacity and features tapered bearings in place of needle bearings for greater load-bearing capability. The 1-1/4" round keyed output shaft supports greaseable output options to reduce spline fretting and corrosion. Call us to confirm proper fit for your application.
