The Chelsea 489 Series Power Take-Off, part number 489XREVX-W3RK or 489XREVXW3RK, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The integral 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. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power from 46 to 55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. The 1-1/4" keyed round output shaft and wire/cable shift mechanism make this a straightforward installation on utility trucks, dump trucks, aerial units, and snow and ice equipment. Call us to confirm proper fit for your application.
