The Chelsea 890EEFJW-B5AF or 890EEFJWB5AF is a hydraulic hot-shift Power Take-Off from the 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions via a 10-bolt mount. The one-piece main shaft eliminates input splines between the PTO and output extension, and the clutch sits at the rear of the housing so the gear section tucks tightly against the transmission for improved clearance. A SAE C ("XS") output flange couples to the pump, and wet-spline technology on the output shaft extends spline service life in demanding duty cycles. Continuous torque rating reaches 670 lb-ft; shaft power is rated at 64 HP at 500 RPM and 128 HP at 1000 RPM. Suited for aerial, fire and rescue, refuse, and truck crane applications where pump space is limited and high torque is required. Call us to confirm proper fit for your transmission configuration.
