The Chelsea 892HDFJW-D5XS or 892HDFJWD5XS is a hydraulic hot-shift power take-off from the Chelsea 892 Series, engineered specifically for Allison 4700 Series transmissions. The 892 Series moves the PTO mounting flange to the rear of the transmission, locating the pump output rearward for improved clearance between the PTO and the frame rail. The unit uses a 10-bolt mounting configuration and an SAE C outlet flange with a wet spline output shaft, extending service life of both the PTO and pump shaft in demanding duty cycles. Applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 892 Series is a single-unit PTO, not a PTO with a separate extension. The clutch assembly sits at the rear of the housing, allowing the gear section to tuck close to the transmission for maximum clearance. The 892 Series can be configured for transmissions equipped with or without a cooler, a retarder, or both. The part number 892HDFJW-D5XS is also referenced as SP892HDFJW-D5XS in distributor catalog records. Parker publishes the 892 Series Parts List (HY25-2892-M1_US) and the 890/892/897/899 Series Owner's Manual for service reference.Parts Manual: Chelsea 892 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
