The Chelsea 890XAFJW-B5XS or 890XAFJWB5XS is a Series 890 Power Take-Off assembly built for Allison 3000 MD and 4000 HD series transmissions. It mounts with a 10-bolt pattern and shifts via hydraulic powershift. The output is an SAE C flange with a wet-spline configuration that lubricates the PTO-to-pump interface to extend shaft life. Continuous-duty torque rating reaches 670 lb-ft (908 Nm), with intermittent torque capability above 501 lb-ft. Shaft output power runs 64 HP at 500 RPM and 128 HP at 1,000 RPM. The extended output shaft design improves clearance for direct pump mounting. Call us to confirm proper fit for your specific Allison application.
