In the installation process of freewheel one way clutch, the factors causing stagnation include the following aspects:
1. Factors of guiding bearing's own processing and manufacturing;
2. freewheel center hole processing and manufacturing factors;
3. Factors of material deformation caused by tightening torque of bolts;
4. Factors of assembling guide bearing methods and so on.
