小四轮拖拉机变速箱二轴左端轴承易损坏的根本原因是轴承选择不合理和使用不当造成的。如果二轴左端还是用的205球轴承,建议你尽快改用12205短圆柱滚子轴承,因为此处用205轴承其强度严重不足。1986年改用12205轴承的实践证明,其使用寿命比205轴承长20多倍,而且不须更换任何其它零件。装配时应注意:“12205”字样朝外,卡簧朝内,装反了就很容易损坏。若二轴左端是刚刚换上的新205
Small four-wheel tractor gearbox The left shaft bearing easy to damage the underlying reason is the bearing selection is not reasonable and caused by improper use. If the biaxial left or use 205 ball bearings, it is recommended that you switch to 12205 short cylindrical roller bearings as soon as possible, because here 205 with a serious shortage of strength bearings. In 1986 the 12205 bearing switch to the practice proved that the service life of 20 times longer than the 205 bearing, and without having to replace any other parts. Assembly should pay attention to: “12205 ” words outward, snap spring inward, installed anti-very easily damaged. If the two-axis left just put on the new 205
