The Chelsea 489XFAHX-V3RF or 489XFAHXV3RF is a Power Take-Off unit from Chelsea's 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the 8-bolt opening without an adapter plate, eliminating a potential leak path and reducing installation time. The 489 Series supports wire/cable mechanical shift operation and delivers intermittent torque in the 201-300 lb-ft range. Output shaft type is a 1-1/4" round shaft with key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Compatible transmissions include Eaton Fuller, Mack, and Tremec. Call us to confirm proper fit for your specific transmission and application.
