Isikrufu sekhompathimenti yesihlungi sikawoyela esinemihlathi emithathu, esaziwa nangokuthi isikrufu sikawoyela esinemihlathi emithathu, siyithuluzi eliklanyelwe ukushintsha izihlungi zikawoyela ezinjinini zezimoto. Ivamise ukufaka imihlathi emithathu elungisekayo ukuze iqinise futhi isuse izihlungi zosayizi abahlukahlukene. Leli thuluzi ngokuvamile lisetshenziswa lapho kushintsha uwoyela ukuze kube lula ukususwa nokufakwa kwezihlungi zikawoyela.
Izici ze-three-jaw oil compartment wrench zimi kanje:
Uma usebenzisa isikrufu sekhompathimenti kawoyela esinemihlathi emithathu, qiniseka ukuthi imihlathi ilungiswe kahle ngobukhulu ukuze ilingane nesihlungi, inamathiselwe ngokuvikelekile futhi usebenzise inani elifanele lamandla ukuze ukhiphe noma ufake isihlungi. Leli thuluzi lingasiza ukwenza ukugcinwa koshintsho lukawoyela kube lula, liqinisekise ukuthi injini yakho isebenza kahle futhi igcina ukusebenza kahle.
