Kumashishini okuvelisa kunye nokulungiswa kweemoto, iinkqubo zemibhobho zisebenza njengesithuthi esisisiseko sokuhanjiswa kwamanzi, kwaye ukuthembeka kwabo kuchaphazela ngokuthe ngqo ukusebenza kwezixhobo kunye nokhuseleko lwemveliso. Ukutyhubela iminyaka yoqokelelo lobugcisa kunye namava entsimi, ndishwankathele amava amaninzi abalulekileyo kuyilo, ufakelo, kunye nokugcinwa kwemibhobho yeauto parts, enokubonelela ngereferensi kubasebenzi boshishino.
Ukukhetha izinto eziphathekayo kubalulekile. Imibhobho yeAuto kufuneka imelane noxinzelelo oluphezulu, ubushushu obuphezulu, okanye imidiya ebolileyo (efana nesipholisi kunye ne-lubricant) ixesha elongeziweyo, ngoko ke imathiriyeli kufuneka ilungelelaniswe neemeko ezithile zokusebenza. Umzekelo, imibhobho ye-aluminiyam yealloyi ikhaphukhaphu kwaye iyachasa{2}}iyaxhathisa, iyenza ifaneleke kwiinkqubo zokupholisa enjini, ngelixa imibhobho yentsimbi engatyiwayo ifaneleke ngakumbi{3}}kwimigca yeoli yoxinzelelo oluphezulu okanye iimeko ezingqongileyo ezigqithisileyo. Nika ingqalelo ekhethekileyo ekubalweni kobunzima bodonga lombhobho. Ukubhitya kakhulu kunokukhokelela ekuqhekekeni, ngelixa ukutyeba kakhulu konyusa iindleko kunye nobunzima bokufakela. Ngokwesiqhelo, ukusetyenziswa gwenxa kwemibhobho yentsimbi yekhabhoni eqhelekileyo ukuthutha isulfure{7}equlathe ukupholisa kubangele ukugqobhoza nokuvuza kwisithuba seenyanga ezintathu. Ukutshintshela kwi-316L yensimbi engenasici yayisombulula ngokupheleleyo ingxaki.
Inkqubo yokufakela imisela ubomi bombhobho. Ukutywinwa kokudibanisa imibhobho kubaluleke kakhulu. Ukudityaniswa kwe-Flange kufuneka kuhambelane ngokungqongqo kwaye kuqiniswe kwi-torque esemgangathweni usebenzisa isitshixo se-torque ukuphepha uxinzelelo. Iinkqubo ze-welding kufuneka zingabikho kwi-pores kunye ne-slag inclusions, kunye nokuhlolwa kwe-X{3} ray kubaluleke kakhulu kwimibhobho yoxinzelelo oluphezulu{4}. Ngethuba lofakelo lwe-hose ye-brake yemoto yorhwebo, i-radius encinci yokugoba ibangele ukunyanzeliswa kokumelana nolwelo, ekugqibeleni kubangele ukulibaziseka kwe-brake. Lo mba uye wapheliswa emva koko ngokulungiselela iiparamitha zokugoba (ubuncinane berediyasi yokugoba Enkulu kuno okanye ilingana namaxesha ama-3 ubukhulu bombhobho). Ngaphezu koko, isithuba sokuxhasa umbhobho kufuneka sibalwe ngokusekelwe kububanzi bombhobho kunye nobunzima bolwelo. Ukuvala kakhulu isithuba kwandisa iindleko, ngelixa isithuba esincinci kakhulu sinokubangela ukungcangcazela kokwaphuka.
Izicwangciso zogcino zifuna uhlengahlengiso oluguqukayo. Ukuhlola rhoqo imibhobho yokonakala komhlaba, iindawo ezidityanisiweyo, kunye neediphozithi zokungcola kwamanzi, kwaye useke isicwangciso sokuthintela esisekwe kwixesha lokusebenza. Umzekelo, imibhobho yerabha kufuneka itshintshwe rhoqo emva kweminyaka emi-2-3, nokuba akukho monakalo ubonakalayo. Ukudibanisa i-clamp kwiindawo ze-vibration ze-high-frequency, kucetyiswa ukuba uphinde uhlolisise isimo sokuqina rhoqo kwiiyure ezingama-500. Ukusetyenziswa kwezixhobo zedijithali (ezifana nokubeka iliso kuthungelwano lwezinzwa zoxinzelelo lwemibhobho) kunokubonelela ngesilumkiso kwangethuba malunga neengozi ezivuzayo kwaye kunciphise kakhulu ukuba nokwenzeka kokusilela ngequbuliso.
Ukuphucula izixhobo zemibhobho yeauto asiyonkqubo enye-yokudubula; ifuna indibaniselwano yezinto zenzululwazi, izenzo zobunjineli, kunye nengxelo yedatha. Kuphela ngokuqwalaselwa okucokisekileyo kwiinkcukacha kunye nokuphucula okuqhubekayo sinokuthi sifikelele ukulingana phakathi kokhuseleko, ukusebenza kakuhle, kunye nolawulo lweendleko.
