The Chelsea 890CAFJW-B3CF or 890CAFJWB3CF is a 10-bolt PTO assembly from the Chelsea 890 Series, engineered for Allison 3000 MD and 4000 HD Series transmissions. It uses Hydraulic PowerShift engagement and delivers an SAE C ("XS") extended output shaft that increases clearance between the PTO and pump. The wet-spline lubrication option (W designator) reduces wear at the shaft interface for sustained duty cycles. Continuous torque is rated at 670 lb-ft, with shaft power output reaching 64 HP at 500 RPM and 128 HP at 1,000 RPM. Intermittent torque is rated at 501+ lb-ft.
