The Chelsea 892HBFJW-B5AF or 892HBFJWB5AF is a hydraulic PowerShift PTO from the Chelsea 892 Series, designed for Allison 3000 MD and 4000 HD series transmissions. It mounts via a 10-bolt pattern and features an SAE C outlet flange with a wet-spline output shaft that reduces wear on both the PTO and pump shaft in demanding duty cycles. The 892 Series uses a one-piece main shaft, eliminating intermediate input splines, and positions the clutch at the rear of the PTO housing so the gear section tucks tightly against the transmission. The pump output is located to the rear of the transmission, providing clearance in tight frame-rail installations. Continuous-duty torque reaches up to 670 ft-lb; output power is rated at 56+ HP. Call us to confirm fit for your specific transmission configuration.
