The Chelsea 897NDFJW-M3CZ or 897NDFJWM3CZ is a constant-engagement Power Take-Off from the Chelsea 897 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The 897 Series relocates the PTO pump mounting flange to the rear of the transmission, tucking the housing and gear section tightly against the transmission to gain clearance where space is tight. Mounting is 10-bolt with an SAE C outlet flange and SAE C output shaft. The one-piece main shaft eliminates the input splines between the PTO and output extension, and wet spline technology at the output extends pump shaft life in demanding duty cycles. Typical applications include aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
