The Chelsea 890RFFJW-B5XV or 890RFFJWB5XV is a 890 Series hydraulic PowerShift power take-off engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and uses a one-piece main shaft that eliminates the input splines between the PTO and the output extension, locating the SAE C ("XS") output flange at the rear of the transmission for improved pump clearance. The clutch sits at the rear of the housing so the gear section tucks tightly against the transmission. Wet Spline Technology on the output extends pump shaft life under demanding duty cycles. The 890 Series continuous-duty torque rating reaches 670 ft-lb, with intermittent torque rated at 501+ lb-ft, and shaft power of 64 HP at 500 RPM or 128 HP at 1,000 RPM. Common applications include aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
