Kuvugurura moteri yimodoka harimo cyane cyane gusimbuza valve, piston, silinderi, cyangwa silinderi, gusya, n'ibindi. Ukurikije ibipimo byububiko rusange 4S, bigomba gusimburwa nibikoresho 4 bifasha, ni ukuvuga piston, impeta za piston, indangagaciro, kashe ya peteroli ya kashe, ubuyobozi bwa valve, shitingi ya crankshaft, guhuza inkoni, imikandara yigihe, ibiziga bikurura.
Niba urunigi rwarageze igihe, birakenewe guhindura urunigi rwigihe, tensioner, usibye gutunganya, amaboko ya silinderi, urusyo rusya, umuyoboro ukonje, ariko nanone ugomba gusimbuza pake ivugurura, kashe ya peteroli yimbere, kashe ya peteroli yinyuma. Ikidodo camavuta ya camshaft, pompe yamavuta, valve yubushakashatsi bwinshi, nibindi, rimwe na rimwe bikenera no gusimbuza ibikoresho byo hanze nka disiki ya clutch, nibindi. Muri make, birakenewe gusimbuza ibice bitizeye neza gusana moteri kugirango byemeze imikorere ya moteri.
