The Chelsea 890HAFJW-B5XS or 890HAFJWB5XS is a 890 Series Power Take-Off Assembly built for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and engages through Hydraulic PowerShift, putting it in service without a manual shift lever. The SAE C (XS) extended output shaft positions the pump mounting flange further rearward than a standard unit, improving clearance between the transmission and the hydraulic pump. Wet-spline lubrication is built in, which reduces wear at the PTO-to-pump shaft interface. Continuous-duty torque rating is 670 lb-ft, with shaft power reaching 64 HP at 500 RPM and 128 HP at 1,000 RPM. Cross-references include 247A-0069 and 247A0069. Call us to confirm fit for your specific Allison application.
