Emva kokuba ivili lesithuthi lifakwe ngokupheleleyo, umda wangaphandle wetayara uya kubambelela ngokuqinileyo kwi-hub flange ukuthintela ukuvuza kwegesi ngaphakathi kwitayara. Ukuba i-hub flange ikhubazekile ngokungqubana, iya kuchaphazela ukulingana kwayo nomda wangaphandle wetayara, ibangele ukuvuza kwetayara. Ke, kwinkqubo yokuqhuba imihla ngemihla, kubalulekile ukunqanda ukungqubana nehabhu yevili kwaye uthintele ukuguqulwa kwehabhu yevili. I-deformation enzima ye-hub flange yevili yesithuthi inokubonwa ngeso lenyama. Ukuba ayinakubonwa, ibonisa ukuba i-deformation ayibonakali. Kuyimfuneko ukususa ivili kuqala kwaye ufefe amanzi kunxibelelwano phakathi kwevili kunye nehabhu yevili. Ukuba amaqamza aveliswa, oko kubonisa ukuba le ndawo yimbangela yokuvuza kwamatayara. Ukuba i-deformation ye-hub yevili lesithuthi ayilungiswanga ngexesha, iya kubangela umonakalo omkhulu ngakumbi - ukugqabhuka kwe-hub yevili. Ukugqabhuka kwe-hub yevili kunokubangela ukuvuza kwerhasi kwi-crack ngaphakathi kwetayara lomoya lokwenene, libe yingozi efihlakeleyo yokugqabhuka kwetayara. Xa le meko iyenzeka, kuyimfuneko ukutshintsha isondo kunye nentsha ngexesha elifanelekileyo, njengoko umngcipheko wokuphuka kwetayara uphezulu kakhulu kwaye usongela ukhuseleko lomntu womqhubi. Ngoko ke, umntu makangakhathali.
