(1) Ibiranga piston na piston biranga amakosa

Ihuza hagati ya piston na silinderi yo gukuraho urukuta bifitanye isano itaziguye na moteri yo kubungabunga ubuzima hamwe nubuzima bwa serivisi. Mugihe cyo gufata moteri no kugenzura, shyira piston hejuru muri bore ya silinderi, hanyuma ushyiremo igipimo cyubugari nuburebure bukwiye muri silinderi icyarimwe. Iyo igitutu cyuruhande gishyizwe, urukuta rwa silinderi na piston bihuye nubuso bwa piston. Koresha impuzandengo kugirango ukande imbaraga zerekanwe gukurura Kuri Birakwiye gukuramo igipimo cyubugari bworoheje, cyangwa ubanza gupima diameter yumwenda wa piston hamwe na micrometero yo hanze, hanyuma upime diameter ya silinderi hamwe na bore gipima. Amashanyarazi yatwaye gukuramo diameter yo hanze yumwenda wa piston nuburyo bukwiye.

(2) Gupima no gukemura ibibazo bya piston na piston

Shira impeta ya piston iringaniye muri silinderi, usunike impeta iringaniye hamwe na piston ishaje (mugihe uhinduye impeta kugirango usanwe byoroheje, uyisunike kumwanya aho impeta ikurikira igenda yerekeza hasi), hanyuma upime icyuho cyo gufungura nubunini igipimo. Niba icyuho cyo gufungura ari gito cyane, koresha dosiye nziza kugirango utange bike kumpera yo gufungura. Kugenzura kenshi bigomba gukorwa mugihe cyo gusana dosiye kugirango wirinde gufungura kuba binini cyane, kandi gufungura bigomba kuba binini. Iyo gufungura impeta bifunze kugirango bipimishe, ntihakagombye gutandukana; impera yatanzwe igomba kuba idafite burrs. Reba inyuma, shyira impeta ya piston mumurongo wimpeta hanyuma uzunguruke, hanyuma upime icyuho hamwe nubunini bwimbitse utatanze pin. Niba gusiba ari bito cyane, shyira impeta ya piston ku isahani iringaniye itwikiriye imyenda ya emery cyangwa isahani yikirahure itwikiriwe numusenyi hanyuma usya neza. Reba inyuma hanyuma ushyire impeta ya piston mumurongo wimpeta, impeta iri munsi ya banki ya groove, naho ubundi impeta yimpeta igomba guhinduka kumwanya ukwiye.
