Crankshaft lankwasawa nakasawa: Kuskuren runout na radial bai kamata ya wuce 0.04 ~ 0.06mm ba. Mujallar Crankshaft: Kuskuren zagaye da cylindricity gabaɗaya baya wuce 0.01 ~ 0.0125mm.

(1) Zaɓi micrometer na waje tare da kewayon da ya dace bisa ga mujallar crankshaft

(2) Auna yawan lalacewa akan babban jarida na crankshaft da haɗin haɗin sanda tare da micrometer na waje bisa ga ka'idar sawa, da ƙididdige kuskuren zagaye da cylindricity. Da farko auna a bangarorin biyu na ramin mai na jarida, sannan zaɓi 90° don sake aunawa. An zaɓi sassa biyu don kowace jarida, kuma kowane sashe an zaɓi kusan 1/3 na tsawon jaridar.

(3) Ba a yarda da tsage-tsalle masu jujjuyawa a saman mujallar crankshaft. Don fashe-fashe, idan zurfin yana cikin girman gyaran jarida, ana iya niƙa shi ta hanyar niƙa, in ba haka ba ya kamata a goge shi.

(4) Lokacin da kuskuren zagaye da cylindricity na injin crankshaft ya fi 0.025mm, ya kamata a ƙasa kuma a gyara shi bisa ga girman gyaran. 3. Gyaran mujallar crankshaft na injunan motoci na Santana da Jetta ya kasu kashi uku na girman girman gyara, tare da matakin daya a kowace 0.25mm.

(5) Kayan aikin crankshaft ya bambanta, kuma bukatun aiki sun bambanta a lokacin gyaran gyare-gyaren sanyi. Kula don hana crankshaft karye ko sabbin fasa.

(6) Kula da hankali don bambance alaƙa tsakanin kuskuren radial da'irar runout na jarida, kuskuren madaidaiciyar axis crankshaft, da curvature.

(7) Lokacin auna girman jarida na crankshaft, zagaye da kurakurai na cylindricity, ya kamata a yi shi tare da ramin mai.
