The Chelsea 890LDFJW-B5AF or 890LDFJWB5AF is a 890 Series hydraulic hot-shift power take-off engineered for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and uses an SAE C ("XS") output flange. The one-piece main shaft moves the pump mounting flange to the rear of the transmission, improving clearance between the PTO and the frame rail without requiring a separate extension unit. The clutch sits at the rear of the housing so the gear section tucks tightly against the transmission. Wet-spline output technology helps extend PTO and pump shaft life under demanding duty cycles. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
