Installation Notes

1. Safety First: Wear appropriate safety glasses and gloves. Ensure the vehicle is properly supported and the area is safe to work on.

2. Gather Tools: Have the correct tools ready, including a torque wrench, appropriate hex socket, and thread cleaner/lubricant if specified by the manufacturer.

3.Inspect Parts: Before installation, check the new bolt (MQ6-01289-0266) for any damage during shipping. Ensure the threaded hole in the component is clean, undamaged, and free of old thread locker or debris.

4. Thread Engagement: Hand-start the bolt to ensure threads are not crossed. It should screw in smoothly by hand.

5. Torque Specification: This is critical. Using a calibrated torque wrench, tighten the bolt to the manufacturer's specified torque value (refer to Sinotruk service manual for the specific application). Do not under-tighten or over-tighten.

6.Torque Sequence: Ilf multiple bolts secure a component (like a flange or cylinder head), always follow the correct crisscross or star pattern tightening sequence to ensure even clamping force and prevent distortion.

7. Thread Locker: Use thread-locking compound only if specified by the manufacturer for that particular application.

8. Post-Installation Check: After a short period of operation, re-check the torque on critical fasteners if recommended in the service manual
