The Chelsea 489XLAHX-H3AF or 489XLAHXH3AF is a 489 Series Power Take-Off assembly built around a one-piece cast iron housing that bolts directly to an 8-bolt transmission opening on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions. This unit has no shift assembly, and the SAE B 2 or 4-bolt flange output has a 1" 15-tooth SAE BB shaft. Intermittent torque for the 489 Series runs 201-300 lb-ft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The tapered bearing design improves load capacity compared to needle-bearing arrangements, and internal parts share commonality with the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
