O le oloa ua mamanuina e le Inisetiute a Ji nan Institute of foundry ma forging machinery, ma e talafeagai mo inter axle ma fetuutuunai transmissionJt faatagaina tele axial radial displacement ma angular displacement, ma ei ai le lelei o le fausaga faigofie, tausiga talafeagai, disassembly faigofie ma le faapotopotoga, maualalo leo. , itiiti le leiloa o le felauaiga lelei ma umi auaunaga ola. E faʻafeiloaʻi e tagata faʻaoga Ina ia mafai ona faʻafeiloaʻi ituaiga uma o faʻafouga masini ma filifiliga ma meafaigaluega faʻapitoa, e mafai e la matou fale gaosi oloa ona tuʻuina atu ituaiga uma o nifo faʻapipiʻi elastic i totonu ma faʻamatalaga eseese, ma talia faʻatonuga e le masani ai e tusa ai ma manaʻoga o tagata faʻaoga.
