1. Detailed inspection of each component shall meet the corresponding standards.
    
2. The perpendicularity of the two end surfaces of the gear and the shaft centerline, and the parallelism of the two end surfaces of the gear should be combined with the internal mesh gear pump gears in good condition.
   
 3. The shaft diameter should meet the technical requirements, and the coaxiality between the shaft sleeve or bearing and the shaft diameter is qualified.
   
 4. Adjust the gear end clearance properly.
    
5. When tightening the end bolts, use symmetrical and even force; move the rotor tightly. If you get stuck, loosen the bolts and tighten again.
