How to Install the Sinotruk HOWO Shift Fork (AZ2214220040) – Technician’s Guide

1. Preparación: Park the vehicle on level ground, drain transmission oil, and safely remove the gearbox. Keep your workspace clean to prevent debris from entering the transmission housing.
2. Access Selector Rail: Remove the side cover of the transmission and locate the selector rail for the 3rd/4th gear assembly. Identify the retaining bolt or pin securing the old fork.
3. Remove Worn Fork: Loosen the mounting hardware and slide off the damaged unit. Inspect for bending, groove wear, or cracks — common after prolonged high-torque use.
4. Install New Fork (AZ2214220040): Slide the new forged steel fork onto the selector rod. Ensure full contact with the synchronizer sleeve; movement should be smooth without binding or lateral play.
5. Torque Specification: Reinstall fastener and tighten to 20–22 Nm. Do not over-tighten — risk of thread stripping is high, especially on aluminum transmission cases.
6. Test Before Final Assembly: Manually move the rail back and forth. Check for even resistance and free travel. Any grinding or sticking indicates misalignment.
7. Rebuild & Refill: Reinstall transmission, reconnect linkages, and refill with GL-5 80W-90 gear oil. Test shifting at idle before road testing under load.
