The Chelsea 489 Series Power Take-Off, part number 489XHAHX-A4RB or 489XHAHXA4RB, is an 8-bolt mechanical shift PTO built for most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. 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 compared to multi-piece designs. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and delivers up to 46-55 HP output, with strong tapered bearings in place of needle bearings for greater load capacity. The output shaft is a 1-1/4 inch round shaft with key. Call us to confirm proper fit for your application.
