This is because both the standard bearing bush and the enlarged bearing bush are marked on the back with machine model numbers and size figures. As long as the bearing bushings are matched with the models and properly installed, the standard bushings can be matched with the bushings on the body And the axis of the correct match. In view of the above situation, I am willing to talk with the new crew about the assembly of bearing bush for reference. 1. Correct choice of bearings To choose with the type of bearings, main bearing and connecting rod bearing to distinguish, do not make mistakes. For example, if one hand mistakenly converts the main bearing of a Shanghai -50 tractor into a connecting rod bearing bush when changing hands,
