The Chelsea 489 Series Power Take-Off, part number 489DAMCX-56XD, is an 8-bolt mechanical shift 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. Output is through a 1-1/4" round keyed shaft. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and up to 55 HP intermittent output power, with shaft power rated at 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
