Kokubili ubakaki ongezansi wembobo yesikwele kanye nabakaki abaphansi abahlukanisiwe bangahlakazwa futhi bahlanganiswe kabusha ngendlela ecishe ifane nenye.Into yokuqala okufanele yenziwe ukususa i-chainring.Amazinyo anepuleti lezinyo.
Susa isikulufu sokulungisa i-crankset ngokuphambene newashi nge-isikhwama sokususa i-crank, screw ithuluzi lokususa i-crank yebhayisikili embotsheni yesikulufu se-crank, bamba i-crank ngenkathi uzungezisa isibambo sethuluzi lokususa i-crank ngokwewashi (uma singekho isibambo, esikhundleni salokho sebenzisa isikrufu), bese uvumela i-shaft yethuluzi lokususa ukuthi lijikeleze ngokukhululeka.Ngenkathi i-crank ixegiswa ngokucindezela ubakaki ongezansi, susa iketanga ngokuyidonsela phansi.Ngalesi sikhathi, kufanele ugweme iketango elidonsa i-derailleur yangaphambili.
Qaphela kakhulu ukuthi ungalimazi i-crankset noma imicu ye-crank njengoba ususa olunye uhlangothi lwe-crank.Lokhu kungenziwa kalula uma unganakile.Lapho ukhipha ubakaki ongezansi onemicu yaseBrithani, imicu engakwesokunxele nengakwesokudla kubakaki abaphansi kufanele ihlehliswe, futhi intambo ohlangothini lwesobunxele lwabakaki abaphansi kufanele kube intambo eya phambili.Imicu eya phambili emaceleni angakwesokunxele nakwesokudla wobakaki ongezansi onentambo yesi-Italian idinga ukuxegiswa ngokwewashi, kuyilapho intambo ehlehlayo ohlangothini lwesokudla lwe-shaft idinga ukuxegiswa ngokuphikisana newashi.Intambo ehlehlayo ohlangothini lwesokudla lwe-shaft kufanele ikhululwe ngokwewashi.
Lapho uqaqa, qala ngokususa leyo engakwesobunxele.Uma uyiqaqa, qala uyikhulule bese uyishiya endaweni yayo;ungayisusi ngokuphelele.Vula isikulufu ohlangothini lwesokudla ngokuphambene newashi ukuze usikhulule, bese usisusa ngesikhathi esisodwa kuzo zombili izinhlangothi.Phakathi nenqubo yokufaka, kubalulekile ukuhlukanisa phakathi kwezinhlangothi ezingakwesokunxele nezingakwesokudla.Ezimweni eziningi, uhlangothi lwesokudla luhambisana nomzimba omkhulu we-eksisi ophakathi, futhi uhlangothi lwesokudla luhambisana nolukhudlwana.Engakwesobunxele incane kulawa amabili.Ukusebenzisa i-lubricant kumdwebo wentambo we-shaft emaphakathi kuzokwenza umsebenzi ube lula futhi kuzokwenza kube mancane amathuba okuthi intambo izolimala.
Uma ufaka, qala ngokubeka i-shaft emaphakathi efanele endaweni, bese uyiphendulela ngokuphambene newashi ukuze uyiqinise.Ngemva kwalokho, faka ohlangothini lwesobunxele endaweni, sebenzisaisikhwama sokususa i-crankukujiya uhlangothi lwesokudla ku-shaft emaphakathi kanye nendiza yabakaki abaphansi, bese uqinisa uhlangothi lwesobunxele.Ngemva kwalokho, lengisa iketango endaweni yokubakaki engezansi ukuvimbela ukuvuza, bese ubuyisela iketanga kubakaki abaphansi.
Ngabe isikhungo se-asi kufanele sigcinwe nini, pho?Ezimweni eziningi, i-axis emaphakathi inquma ukuthi ukuphikiswa komsindo okungavamile kuphezulu kakhulu, futhi ngenxa yalokho, i-axis ephakathi kufanele igcinwe.Ukunakekelwa kwale divayisi ngokuvamile kuhlanganisa ukungeza ibhotela nokuhlanza noma imaphi amabheringi angaphakathi noma amabhola okungenzeka akhona.Esimweni lapho amabhola athwalayo noma ezinye izingxenye ezigoqayo seziphenduke Lapho ukuguga nokudabukile kubalulekile, kufanele ubeke esikhundleni.
Ngaphambi kokwenza noma yikuphi ukulungisa, qala ngokususa ngokucophelela i-bearing ku-shaft emaphakathi yebhayisikili usebenzisa i-ibhayisikili crank puller, bese usebenzisa i-taper ebukhali ukuze uphakamise ngokucophelela isembozo sothuli kusuka ekuthwaleni.Qaphela ukuthi ungaklwebheli noma ungalimazi ngenye indlela ikhava yothuli.Uma kwenzeka ukuthi into engekho ibhotela, ukhululekile ukuyifaka ngokushesha.Uma kwenzeka kutholakala ukungcola, kungase kusetshenziswe uphalafini noma uphethiloli ukuyihlanza.Uma amasongo angaphakathi nangaphandle okuthwala atholakala eguquguquka, lokhu kubonisa ukuthi ukuthwala sekufinyelele ekupheleni kokusebenza kwayo futhi kudinga ukushintshwa.
