The Chelsea 892CCFJW-B3CS or 892CCFJWB3CS is a hydraulic hot-shift power take-off from the Chelsea 892 Series, designed specifically for Allison 4700 Series transmissions. The 892 Series locates the PTO and pump mounting flange at the rear of the transmission, tucking the housing tightly to the frame rail and creating clearance that a standard side-mount PTO cannot provide. The unit uses a one-piece main shaft that eliminates input splines between the PTO body and the output extension. Output is through an SAE C flange with wet spline technology, which extends pump shaft life under continuous-duty and demanding conditions. The 10-bolt mounting pattern and rear support bracket give the assembly a stable, compact fit. Call us to confirm proper fit for your truck and transmission configuration.

Additional Information
The Chelsea 892 Series was engineered for applications where pump space and high continuous-duty torque are both critical. Typical uses include aerial trucks, fire and rescue vehicles, refuse trucks, truck cranes, and snow and ice equipment. The unit mounts like a standard side-mount PTO but adds a bracket at the rear of the transmission for added support. This is a single-unit design, not a PTO with a separate extension. Parker's 890/892/897/899 Series Owner's Manual and the 892 Series Parts List (HY25-2892-M1_US) are available for installation and service reference.
