The Chelsea 489 Series Power Take-Off, part number 489XFAHX-V3GY or 489XFAHXV3GY, is an 8-bolt PTO assembly 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 adapter plate and the leak path that comes with it. Intermittent torque capacity for this series is 250 lb-ft (339 Nm). The wire/cable mechanical shift drives a 1-1/4" round output shaft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part available from Pro Gear and Transmission.
