Decalinate kanye nokuhlanza i-valve
Okuqukethwe
Okokufundisa: Ukuqaqa, Ukuhlanza kanye Nokweqa Amavavu
6 Kawasaki ZX636R 2002 Sports Car Restoration Saga: Isiqephu 12
Inkinga ngezinjini ezivuthayo zangaphakathi ama-hydrocarbon angashile azinza endaweni evuthayo yenjini futhi acwebezele ngokushisa enze izinsalela zekhabhoni. Impela wukungcola okuphazamisa ukusebenza kahle kwenjini, okuwumphumela wokuqala wokuphelelwa amandla kanjalo nokuguga kwamavalvu. Ngakho-ke, kuyadingeka ukuhlanza noma ngokunembe kakhudlwana decalamine ukuze injini ibuyele ukusebenza evamile.
I-valve yokungena, noma ngabe eyokuqala noma inkambiso, iyabiza. Lindela kusuka kuma-euro angama-40 kuye kwangama-200 ukuthola ivalvu, kuye ngomsebenzi wayo nezinto ezibonakalayo. Ngakho-ke kuyafaneleka, ikakhulukazi lapho injini isivele ihlakaziwe, ukuchitha isikhathi lapho uhlanza futhi uyakhe kahle. I-valve iyingxenye encane, kodwa iqukethe izingxenye eziningi ezinencazelo yazo.
Injini yethu engu-4-cylinder inamavalvu angu-16. Lokhu kuhambisana nendilinga ngayinye encane eboniswe esithombeni sekhanda lesilinda elihlakaziwe. Cabanga ngezindleko, noma kunalokho ukonga ngokudla.
Ngakolunye uhlangothi, angifuni ukuphuthelwa mina lapho ngihlanza noma ngiqaqa / ngihlanganisa kabusha. Ngaphezu kwalokho, ithuluzi elikhethekile liyadingeka ukuze ukhiphe isiphethu futhi uyisuse.
Ngenhlanhla, naphezu kokwehluleka kwami, okuvame ukungihlupha, ngihlangana nabantu abahle. U-Edouard, umakhenikha omnene we-Rollbiker e-Boulogne, e-Billancourt, unginikeza usizo lwakhe. Kungeseluleko sakhe esihlakaniphile nesinobungane ukuthi ngiye endlini yakhe, ngiphethe isilinda, ukuze ngiyokwenza izifundo ezisheshisiwe zemishini kanye nomboniso wokuhlanza okuphelele nokudlula nge-valve. Isimo sabo sokungcola sibalulekile futhi ukubukeka kwabo akukhanyi kakhulu, ake sibone ukuthi umpheki wethu ohloniphekile nomakhenikha waseBoulogne angenzani.
Ungikhombisa izimpawu zokushukuma komzimba, angithulise futhi angiphonse kubhavu omkhulu ukuze ngifunde ukubhukuda. Okungcono nakakhulu, ngomusa unginikeza amathuluzi adingekayo ukuze ngimbuyisele egalaji ukuze ahlanganyele. Makabongwe izikhathi eziyinkulungwane. Ngakho-ke ngizohamba ne-tappet ye-valve elayishwe entwasahlobo kanye nokujikajika. Ngakolunye uhlangothi, i-lapping paste isendaweni yokungcebeleka eyi-ZX6R 636, lapho mina no-Alex sizoqeda khona ukuqondisa. Kwabangafundile, ngihlolisisa lesi sifundo ngokuningiliziwe.
Amathuluzi okusesha athile
Amathuluzi ashintshiwe ayatholakala ku-inthanethi. Ngabheka, uma kwenzeka.
I-valve ye-compressor elayishiwe yasentwasahlobo iboniswa ngentengo ephansi ecishe ibe ngama-euro angama-20. Izinga okufanele kwengezwe ngalo izinga lokushaya kwe-valve. Kuyinkomishi yokumunca enamathela ekhejini ye-valve (ikhanda layo) futhi isetshenziselwa ukuyizulisela yona ngokwayo ukuze kwenziwe kabusha uphawu oluphelele phakathi kokufinyelela kwayo (ingxenye ethintana nekhanda le-cylinder) kanye nomzimba ikhanda le-cylinder. Kunamamodeli amabili ezinduku: igundane elishintshwayo kanye negundane elikwazi ukujwayela umshini wokubhoboza noma we-compressor. Amanani avela kuma-euro angu-5 kuya kwangu-300 ... Kimina kuzoba yi-classic, ukuze nje ugcine umuzwa omuhle wokumelana nokusanhlamvu ngesikhathi sokungqubuzana.
Ngempela, kumelwe sengeze inhlama edumile yokuqhoqhobala endleleni. Lokhu kuzovumela izindawo ezimbili zokuxhumana ukuthi zivumelane nezimo, zizisuse futhi zizisuse njalo nakunoma yimuphi umdlalo. Ngakho, noma iyiphi ingozi ukuvuza. Lokhu kusebenza kubucayi futhi ukunamathisela okucwecwayo kungaba yizinhlobo ezimbili: okusanhlamvu okumahhadla futhi okusanhlamvu. Endabeni yami, okusanhlamvu okuhle kwenza izimangaliso. Siyibeka phezulu kancane ukuze "siyipholise" futhi siyizungezisa, siyizungezisa kuze kube yilapho uzwa noma yikuphi ukumelana ne-valve, kuze kube yilapho yonke into ishelela, ikhombisa ubuso obushelelezi. Kuhle, lokho kuphawuliwe.
Izinyathelo zokuvuselela ama-valve
Buyela egalaji ukuze ubambe iqhaza namanye ama-valve angu-15. Ngokusobala, ngamagama alula, i-636 inama-valve angu-4 isilinda (ama-valve amabili okungenisa, i-2 exhaust) ngakho-ke inani lama-valve angu-16 adinga ukusabalalisa kabusha. U-Edward wangibonisa enye yazo, ebuka ukuthi yonke into izohamba kahle, ngakho nganginezinto ezingu-14 okufanele ngizenze. Wathembisa ukuthi uzokhathala futhi abe yingozi, akunjalo.
Kusukela ekusabeni kokuqala okudlule, ngizizwa ngikhululekile. Ukuzivuselela kwakuwumsebenzi omnandi. Ithinta amavalvu angumongo webhayisikili. Kudinga ukunemba, ukugxila, ukuthinta okuphephile, kanye nendlela yokugomela eyalungiswa ngokushesha njengoba injabulo ikhula.
Susa i-valve ngayinye nge-valve ye-compressor elayishwe entwasahlobo
Ukuphatha kulula. Ngibeka ikhanda lesilinda "phansi". Ngakho-ke, ama-valve atholakala ohlangothini lwe-"carpet" lwebhentshi lomsebenzi futhi ahlala ebanjwe ngokuqinile ngokucindezela intwasahlobo yawo ngokumelene nodonga lwekhanda le-cylinder.
Ngibeka isiphakamisi se-valve esizimisa phakathi nendawo lapho ngiqinisa i-clutch yaso. Ingxenye eyisiyingi futhi egobile, ehambayo, ixhumene "nenkomishi" ebambe amacembe. Enye ihlezi ngakolunye uhlangothi lwekhanda lesilinda. Njengoba ngiqinisa i-hug, ucindezela inkomishi (inkomishi eqinisa okhiye) futhi ucindezela isiphethu se-valve. Lokhu kukhipha okhiye (engiphinde ngibabize ngokuthi ama-crescent), abavame ukubamba umsila wevalvu ezingeni lokopha elihlinzekelwe ukubekwa kwabo.
Lolu uhlobo lwesimiso sezimayini esiphethwe ingcindezi, iziphethu uze ushaye irabha noma ikepisi.
I-valve iwa ngokwemvelo futhi ngiyakha kabusha ngokuphakamisa ikhanda lesilinda. Ukuze ngingalahlekelwa yinyanga ecwebezelayo, ngikhulula i-compressor yasentwasahlobo. Bayiziboshwa futhi. Futhi zingasuswa ukuze kube lula ukuphunyuka kwesikhathi esizayo. Hhayi-ke, uma kwenzeka, ngabuza, ngisho noma kunzima kakhulu ukubadukisa ngesikhathi sokudilizwa, singawathenga futhi, kusukela ku-2 kuya ku-3 euro ... ngayinye.
Ukupholisha i-valve
Kuleli qophelo, uma i-valve ngayinye ihlakazwa futhi ikhishwa emzimbeni (yeka ikamelo elihle, noma kunjalo!), Ngiyihoxisa ngobumnene ku-drill chuck (intambo noma engenazintambo) bese ngiphendulela ikhanda lami! I-carousel ehambisana nomcimbi neshizolo lokhuni elibukhali. Ithuluzi lokususa i-valve ngaphandle lingasetshenziswa, kodwa bengingenaso isisombululo samakhemikhali nanoma yini esebenza kahle njengalokhu engikwenzayo njengamanje. Akukho ukwesaba ukuhlasela isakhiwo: siqinile kusuka kuqinile. Ngakolunye uhlangothi, ngiyaqaphela kakhulu emaphethelweni e-valve: ungawahlaseli, njengesihlalo (ngezansi). Ngokusobala, ukuthatha isithombe ngezandla zombili akulula ukufanekisa iphuzu, kodwa uthola isimiso.
Ngiyajabula ukubona indlela engifaka ngayo i-valve yangemuva ku-chuck. Lokhu kuthatha imizuzu emi-5 kuya kweyi-10 ivalvu ngayinye, kuye ngesimo sayo kanye nezinyathelo zokuphepha engizithathayo. Ngiyabonga ngokuthola imodi elungile yokuzungezisa kahle ukulungisa isivinini esifanelekile ukuze sikwazi ukususa izikali nezinsalela. Ngiyabaleka ngokoqobo, ngilungisa ukuthinta. Ngiyabuka, ngitadisha ngokucophelela, ngiyabuka, ngamafuphi, ngiyakuthanda!
Ukushintsha I-Tail Valve Seals
Uma i-valve isibuyele esimweni sayo sokuqala (esihle kakhulu!), Sekuyisikhathi sokuyibuyisela endaweni, ngiphathisa u-Alex umsebenzi. Unomthwalo wemfanelo wokushintsha nokufaka ama-valve tail seal. Ayifake endlini yakhe angazibeki nezinyanga ezicwebezelayo. Lokhu kuvumela ukuthi ijikeleze ngokukhululeka ekseni yayo yomsila.
Iziqu ze-valve
Manje kufanele ubeke inkomishi yokumunca isiqu phezu kwekhanda levalvu bese ufaka igravel (ingxenye engezansi negobile yekhanda levalvu) usebenzisa inhlama yokuhlikihla ngomunwe wakho.
Njengoba igama liphakamisa, indima yalo ukusebenzisa izindawo ezimbili zokuxhumana ukuze zifane kahle futhi zidale uphawu oluqinile. Sazi kanjani ukuthi lokhu kwenziwa?
Ukunyakaza kwe-frictional kuyenziwa (ukushintshashintshanisa ukusuka kwesobunxele kuya kwesokudla), i-valve isendaweni emzimbeni wayo. Ekuqaleni, uzizwa ngesiqu sesiqu njengobulukhuni.
Uhlamvu olunyamalalayo njengoba indawo ifanelana futhi inhlama isebenza. Lolu wuhlobo lokupholisha olubushelelezi izindawo ezingaphezulu. Lapho i-valve igubha njengebhotela, ukuphenduka kuqedile. Ukuze ube nenhliziyo ehlanzekile, ungayivivinya kanye ngokubuyisela inhlama ethile: okusanhlamvu kuphelile.
Njengesikhumbuzo, u-Alex, umakhenikha ofunda umsebenzi onyakeni wakhe wokuqala esikoleni sokukhanda izithuthuthu e-Angoulême, useholidini ekhaya. Ngokucophelela, ngenkuthalo, uwuthatha ngokungathi sína lo msebenzi. Ukungathí sina okungabalulekile kokuhlinzwa okunjalo, okubalulekile. Ivalvu enyakazayo, iyaxebuka noma okuthize, futhi injini isifile. Ukusebenza ndawonye kusivumela ukuba sibe nesikhathi esimnandi ndawonye.
Woza, ake sihambe imizuzu engu-10-15 yokwelashwa ... nge-valve! Futhi kukhona 14 ... ngizodlula u-Alex, isenzo sigugile ngokuhamba kwesikhathi. Ngomusa, ukusebenzisa i-seaming, i-lapping paste namafutha endololwane kuzokwenziwa ngobunono. Sicabanga ukuthi singama-Cro Magnon sizama ukukhanyisa umlilo lapho siphendulela induku ezandleni zethu, njengoba sehla senyuka ukuze siqinisekise ukubekwa kwayo kahle. Kuthatha isikhathi nesikhathi, kodwa futhi, isenzo siyaheha.
Ukuthola kabusha kwe-Crescent
Ngakho-ke, singabuyisela ama-crescents endaweni, futhi lokhu akulula ngaso sonke isikhathi: avame ukutshekiswa. I-screwdriver encane ingasiza ukuwaqondisa futhi adambise isimo. Qaphela ukubuyisela yonke into endaweni: uphawu lomsila we-valve ogxumayo, noma ama-crescents enza umgqomo, futhi sibi: izokhulula i-valve ekamelweni elivuthayo, futhi lapho ... sawubona, umonakalo.
Ukuhlolwa kokuvuza kwekhanda lesilinda
Uma wonke ama-valve esesendaweni futhi engasasebenzi, kuzoqinisekiswa ukuthi ikhanda lesilinda eliphakanyisiwe lizodala isikhala esivalekile ngokuphelele futhi esingavaliwe. Ahlinzeka ngokuminyanisa okuhle kanye nokusha okuhle nokukhipha amagesi ekuqhumeni okudalwe yi-spark plug. Ukwenza lokhu, kulokhu ngiphendulela ikhanda le-cylinder kanye nama-valve akhomba esibhakabhakeni bese uthela uphethiloli ku-crucible. Uma ngiwabona egeleza ngakolunye uhlangothi, ebhentshini lomsebenzi noma endwangu, kunenkinga futhi kufanele uhlole ukubekwa kahle kwe-valve noma uphinde ukugoqa okude nokusetshenziswayo ngokunamathisela okunolaka, okusanhlamvu okumahhadla ukuze uqale. bese kuba amabele amahle. Uma lokho namanje kungasebenzi, kuzodingeka sicabange ukushintsha i-valve (ama) okukhulunywa ngayo, noma ukulungisa kabusha ikhanda lesilinda, noma ukulishintsha, noma ... ukumemeza kahle.
Uma kungenzeki lutho, kusho ukuthi konke kuhamba kahle. Futhi esimweni sami, konke kuhamba kahle. Ukuwina okuncane ongakujabulela njengezikhathi ezichithwe ekuqeqesheni oomakhenikha abasindayo "bemfashini yakudala", kanye nalezo ezabiwe no-Alex. Kimina, vele, iphinde ibe umakhenikha: ukushintshana.
Sizokwazi ukuphakamisa ikhanda le-cylinder nokusabalalisa. Kuzoqhutshwa…
