The Chelsea 890CDFJW-B3ZS or 890CDFJWB3ZS is a hydraulic PowerShift power take-off engineered specifically for Allison 3000 (MD) and 4000 (HD) series transmissions. It uses a 10-bolt mounting flange and an SAE C ("XS") output shaft, delivering continuous-duty torque up to 670 ft-lb and intermittent torque rated at 501+ lb-ft. Shaft power reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The one-piece main shaft eliminates input splines between the PTO and the output extension, placing the clutch at the rear of the housing so the gear section tucks tightly against the transmission. The wet-spline output lubricates the shaft interface to extend service life in demanding duty cycles. Call us to confirm proper fit for your application.
