The Chelsea 890CAFJW-B3CS or 890CAFJWB3CS is a 890 Series power take-off assembly engineered for Allison 3000 MD and 4000 HD series automatic transmissions. It mounts via a 10-bolt pattern and uses hydraulic PowerShift engagement. The SAE C ("XS") output shaft and SAE C outlet flange deliver up to 670 lb-ft of continuous-duty torque and 128 HP at 1,000 RPM shaft speed. The wet-spline design lubricates the PTO-to-pump interface to extend shaft life, and the extended output shaft provides added clearance for direct-mount pump installations.
