The Chelsea 890MAFJW-B5XS is a 10-bolt, hydraulic PowerShift Power Take-Off from the Chelsea 890 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The 890 Series moves the pump mounting flange to the rear of the transmission, improving clearance where space is tight. The output uses an SAE C flange with Wet Spline technology, which extends PTO and pump shaft service life in demanding duty cycles. The one-piece main shaft eliminates input splines between the PTO body and the output extension. Common applications for the 890 Series include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes. Available from Pro Gear and Transmission.
