1.Mbere yo gushiraho impeta ya piston, igikonjo cya piston kigomba gusukurwa kugirango harebwe niba epfo na ruguru no hejuru no hepfo yibice byimpeta idafite imyanda kandi ntabwo byangiritse.

2.Gukoresha pisitori idasanzwe ya pisitori kugirango ushyireho, ntigomba gushyirwaho intoki;

3.Gushiraho bigomba guhera munsi yimpeta yamavuta. Mugihe ushyiraho, menya neza ko TOP isura yimpeta ya piston hamwe nijambo "TOP" ireba hejuru.

4. Witondere kwishyiriraho impeta yamavuta menshi: banza ushyireho isoko yinkunga, hanyuma ushyireho scraper, scraper igomba gufungwa mucyerekezo cyumwobo wa pin, nyuma yo gushiraho scraper yo hejuru, funga isoko yinkunga, kwishyura kwitondera kudahuzagurika, hanyuma ushyireho scraper yo hepfo;

5.Iyo ushyizeho impeta yamavuta yisoko ya coil, fungura isoko hanyuma uyishyire mumashanyarazi, funga intera, hanyuma ushyire umubiri wimpeta yamavuta mumashanyarazi, gufungura impeta yamavuta bigomba kuba bihabanye igitereko cy'isoko;

6.Ntukoreshe imbaraga nyinshi mugihe cyo kwishyiriraho, cyangwa impeta ya piston izacika. Gufungura impeta ya piston yashyizweho bigomba kwirinda umwobo wa piston hamwe nicyerekezo gihagaritse cyu mwobo wa piston, kandi imyanya yo gufungura ya buri mpeta igomba guhindagurika kuri dogere 90-120. Impeta ya piston imaze gupakirwa mumashanyarazi, igomba kuzunguruka kugirango yirinde gukomera;

7.Nyuma yimpeta ya piston imaze gushyirwaho, isuzumabumenyi riri hagati yisura yo hejuru nu munsi yo hepfo no hejuru no hepfo yuruhande rwimpeta. Icyemezo ntarengwa ntigishobora kurenga 0,10mm. Niba intera yemewe itariyo, nyamuneka reba niba impeta ya piston ihuye na piston. Impeta ya Chrome isize piston ntigomba gukoreshwa nurukuta rwimbere nayo ni chrome isize silinderi.
