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.
