The Chelsea 489XFAHX-C5RB or 489XFAHXC5RB is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO opening, including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, cutting installation time and eliminating an extra leak path. This unit uses a special shift control and bracket kit and delivers an intermittent torque rating in the 201-300 lb-ft range, matching the torque capacity of the 442 Series. The 489 Series supports shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call Pro Gear and Transmission to confirm proper fit for your specific transmission and application.
