The Chelsea 489 Series Power Take-Off, part number 489XLAHX-A5RY or 489XLAHXA5RY, is an 8-bolt PTO designed 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. This unit uses an air shift and delivers intermittent torque rated at 201-300 lb-ft. The output is a rotatable DIN 5462 pump mount with a DIN 5462 shaft (B8x32x36). Tapered bearings replace needle bearings for greater load-bearing capability. Pro Gear and Transmission carries this genuine Chelsea part for utility trucks, dump truck and trailer, and aerial and municipal equipment applications.
