The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-P3GK or 489XLAHXP3GK, is an 8-bolt mount PTO designed for 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. 12V electric/air shift is standard on this unit, with a greaseable SAE B 2 or 4-bolt flange and 7/8" 13-tooth SAE B shaft. The 489 Series shares internal parts with the proven 442 Series and delivers intermittent torque of 201-300 lb-ft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
