The Chelsea 892HFFJW-D5XS is a hydraulic hot shift power take-off built for the Allison 4700 Series transmission. Part of the 892 Series, it uses a 10-bolt mounting configuration and positions the pump output flange to the rear of the transmission, improving clearance in tight frame-rail installations. The output shaft and flange are SAE C type, and the wet spline output extends PTO and pump shaft life under demanding duty cycles. The one-piece main shaft eliminates input splines between the PTO and the output extension, and the clutch sits at the rear of the PTO housing to allow the gear section to tuck tightly against the transmission. Typical applications include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes. Also referenced as 892HFFJWD5XS. Call us to confirm proper fit for your application.
