The Chelsea 489ZHDAX-V3RK or 489ZHDAXV3RK is a 489 Series Power Take-Off unit built for 8-bolt manual transmission openings, fitting transmissions such as Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating an additional potential leak path. This series delivers intermittent torque in the 201-300 lb-ft range, with output power rated at 46-55 HP. The output is a rotatable SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your specific transmission and application.
