The Chelsea 489 Series Power Take-Off, part number 489XCAHX-A5GQ or 489XCAHXA5GQ, is an 8-bolt PTO designed for 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 need for an adapter plate and reducing potential leak paths. This unit uses wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Call us to confirm proper fit for your transmission and application.
