the correct position of trunnion is showed as follows, be in parallelogram slightly, so as to avoid sliding down due to incline. Strictly prohibit any two trunnions to be in eight, or the surface of trunnion will easily be abraded. Unevenness on tire surface, dryer vibration will be caused during run.
