489XFAHX-P3AF Chelsea PTO Assembly

The Chelsea 489 Series Power Take-Off assembly, part number 489XFAHX-P3AF or 489XFAHXP3AF, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path while delivering the same intermittent torque capacity as the 442 Series (250 lb-ft / 339 Nm per application pages). The output is an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. Shift type is 12V electric/air shift. Output power reaches 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your application.
