The Chelsea 892HCFJW-B5XK or 892HCFJWB5XK is a hydraulic PowerShift power take-off from the Chelsea 892 Series, engineered to fit Allison 3000 MD and 4000 HD Series transmissions. The 892 Series mounts to the transmission's 10-bolt pad and positions the pump output flange to the rear of the transmission, tucking the housing and gear section tightly alongside the frame rail for improved pump clearance. The output shaft uses a SAE C ("XS") flange with Wet Spline technology to extend PTO and pump shaft life under continuous heavy-duty operation. Continuous-duty torque for the series reaches up to 670 ft-lb; shaft output is rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM. Applications include aerial trucks, fire and rescue vehicles, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
The Chelsea 892 Series is a single-unit PTO, not a PTO with a separate extension. The main shaft is one piece, eliminating input splines between the PTO body and the output extension. The clutch is located at the rear of the PTO so the housing and gear section sit tightly against the transmission for maximum clearance. The unit can be configured for transmissions with or without a cooler, retarder, or both. Typical applications include aerial trucks, fire and rescue, snow and ice equipment, refuse trucks, and truck cranes.
