Faka esikhundleni i-gasket yekhanda le-cylinder uphinde uhlanganise ikhanda le-cylinder nokusabalalisa

Zonke izinyathelo: ukubeka ama-seams, i-camshaft, ukulungiswa kweketanga lesikhathi

I-Kawasaki ZX6R 636 Sports Car Restoration Saga 2002: Isiqephu sama-14

Ikhanda lesilinda selibuyiselwe ekugcineni. Sihlakaza yonke into futhi sihlanza ama-valve nge-potassium. Konke kubonakala kungenasici futhi kuvumelana nokuhlanganiswa kwekhanda le-cylinder.

Sibona umehluko phakathi kwama-valve ahlanzwa kwesokunxele kanye nabanye

Okusele ukukhipha i-stud ephukile lapho ususa umugqa wokuqeda bese ugoqa lowo oseqale ukuphenduka ube yikhanda le-cylinder.

Iphini lezinwele eliphukile kanye nephini lezinwele ezingekho

"Kukhona okungaphezu kokwanele." Bekumele ngisole ukuthi kuzoba lula kakhulu. Futhi kwakungenjalo nhlobo. Ayikwazi ukususa iphinikhodi. Ngokufudumeza? Niet. Ngokudabukisa? Niht. Ngokuphikelela. Cha cha. Ngomsila wengulube? Akukho okungcono. Akenzanga lutho. Umphumela? Owine iGoujon kwa-KO! Ukuziphindiselela ngomjuluko nemibono ongayithola.

Isixazululo mhlawumbe kungaba ukusika i-stud flush, ukuthepha bese ubuyisela inetha elinqanyuliwe. Kodwa anginaso isikhathi! Ngakho-ke ngizovala i-manifold ngokuhlanzeka kakhulu ekhanda lesilinda ngokunamathisela kwezinga lokushisa eliphezulu ukuze ngigweme noma yikuphi ukuvuza okwengeziwe. Ingxube yezingxenye ezimbili engeke iyeke ukuzibonisa yona. Kulokhu, isisombululo esihloliwe nesivunyiwe.

Ukuhlanza i-piston

Ama-piston abonakala endaweni evelele nawo azofaneleka ukuhlanzwa okuhle

Ama-pistons nawo azofaneleka ukuhlanzwa kahle. Ngibheka isimo samahembe epaseji ukuze ngingalithathi ibhantshi lebhonasi. I-RAN.

Hhayi-ke, ngiphinde ngathatha ithuba ngabona amakhanda episton ukuze ngiwahlanze kahle nangempumelelo futhi ngibheke isimo segumbi elivuthayo kanye nolayini walo. Qaphela ukuthi ungawisi lutho kuyo, ingaklwebha ihembe lakho noma ingene enjinini engezansi... Futhi, lokho kulungile. Sengivele ngiyayithanda le 636 ixazululiwe! Ohambweni, ngiqedela ukwakha kabusha ngemva kwalo mgijimi.

Ukusonga ikhanda le-cylinder kanye nokubeka ukuxhumana

Kuleli qophelo, kuzodingeka uhlanganise ikhanda le-cylinder bese ufaka uphawu lwekhanda lesilinda. Isici esibalulekile sesithuthuthu esiqinisekisa ukuhamba kahle koketshezi kanye nokucinana kwekhompathimenti ngayinye futhi, ngaphezu kwakho konke, igwema ukuxubana. Ikakhulukazi intekenteke, imelana nokushisa, amakhemikhali futhi, yiqiniso, ukucindezeleka kwemishini. Kuthathe isikhathi eside ukuthola lelo phawu oludumile lwe-cylinder head…. Hlehlisa: Ngizobheka emuva kuwe (ngeseluleko esihle) esihlokweni esishicilelwe kakade.

Ngemva kokudiliza ikhanda lesilinda, sasilapho

Ngenhlanhla, izigxivizo ezinenjini ephezulu sezifikile futhi yonke into ibonakala ibuyele kokujwayelekile, ngokoqobo nangokomfanekiso. Ngakho-ke, ngiyilungiselela ngendlela yokuthi indiza yokuxhuma, i.e. indawo eyisicaba ngaphansi kwekhanda lesilinda, yayibukhali ngangokunokwenzeka. Injini ephansi kanye nezindawo eziphakeme zenjini ezithinta uphawu lwe-cylinder head zibalulekile: zilungiselela isivalo esifanele.

Isivalo esisha sekhanda lesilinda sidingeka kakhulu!

Qaphela, uphawu lwekhanda le-cylinder kufanele lubekwe ngendlela efanele: awukwazi ukwenza iphutha, futhi uphawu akufanele lufakwe isicaba noma lukhubazekile ngokungalungile. Omaka bayatholakala balokhu, okuhlanganisa neyodwa enikeza indawo ephezulu yokuxhuma. Lesi sici esidumile sekhanda le-cylinder, engigijime kakhulu ngemva kwalokho, ligwema izingxube phakathi kwamasekhethi okugcoba (amafutha) kanye nokupholisa (ukupholisa uketshezi). Iyafa futhi ngezinga lokucindezelwa kwenjini. Ingcindezi, okwamanje, nginayo! Uma ngeqa lokhu, injini ingase iphuke ngesikhathi esithile.

Kushintshwe ikhava yekhanda yesilinda

Ngibeka uxhumano, nginqume ikhanda lesilinda libe izinti ngandlela-thile, futhi ngilungise ucingo olunamathiselwe kumjikelezo wokusabalalisa ngaphambi kokuwuhlanganisa ngomzimba. Ngokusobala, akuyona yonke into ehlelwa kahle okokuqala nxazonke, kodwa iyonke ayihambi kabi kakhulu. Ubona okuningi. Okungenani kuze kube yilapho izindawo zokusabalalisa sezibuyile endaweni. Kuthathe izandla eziyisithupha (u-Alex, uKirill kanye nami) kanye namakhanda amathathu ukuthola ukuthi i-WD40 encane futhi yayanele ukuvumela into embi ukuthi ithathe indawo yayo.

Uchungechunge lokusabalalisa lwase lulungele ukudonselwa endlini yalo. Intambo esidladleni, i-screwdriver engiyikhiye phezulu kwekhanda le-cylinder, ngiyayi-ayina bese ngiyishintsha. Ekugcineni, sithatha indawo yakhe, u-Alex, uKirill kanye nami. UKirill akayona into engaphezu komphefumulo wegaraji ngokubamba iqhaza, kodwa sizobuyela kuye.

I-Camshaft nebhande lokuvala

I-shaft engancibilika enomaka wokulawula isileyiti

Bese ngibeka ama-camshafts endaweni. Qaphela, kukhona okubili okuhlukene, ngakho-ke landela ukumaka: IN kwangaphakathi kanye ne-EX yangaphandle, okungukuthi, isiqondiso lapho umaka uphendukela khona ngokuhlobene nenjini, bese ngifaka ibhande kuma-sprockets. Kalering igama. Ngishintsha ama-tampon amabili, ukuhlinzwa okungithathe isikhathi esingakanani ngenxa yokuntuleka kwendlela elungile kanye ne-shuya ejabulisayo ngezinye izikhathi edingekayo kumuntu oqalayo. Ihhashi elibi! Ngabe sengibeka eceleni i-tensioner, ecindezela ngokushesha iketanga, elinwebeka. Ilungele ukugqokwa nokuhlolwa kokulungiswa kwesikhathi esizayo.

I-Tensioner ye-Timing chain isesimweni esihle

Isikhathi sochungechunge lokusabalalisa

Ngakho-ke, manje sikhuluma ngesikhathi sochungechunge lokusabalalisa. Ngomqondo othile, ngivumelanisa ukusebenza kwenjini ephansi kanye nenjini ephezulu. Ukwenza lokhu, ama-pistons kufanele abekwe endaweni efanele ngokuphendula umaka we-axis we-crankshaft onyakazayo kumaka ongashintshi (ngemuva kokudiliza indlu ukuze ufinyelele kuyo). Leli phuzu eliphansi libeka ukusabalalisa, bese sihlola ukuthi sinenombolo efanele yezixhumanisi phakathi kwezihlahla ezimbili. Ngiphinde ngihlole ukuthi izimpawu ze-camshaft zihambisana kahle nendiza ephezulu yokuhlangana. Futhi manje ngiyajabula: konke kulungile. Hhayi inqwaba yemidlalo. Lutho. Iketango lisendaweni ekahle, liqinile futhi lisesimweni esihle. Ngimamatheka. Ukuze kube kuhle.

Manje kufanele sihlanganise wonke lo mhlaba omncane. I-torque wrench iyimpoqo futhi indlela ayiguquki. Izinqubo ezibonisiwe kufanele zihambisane nencwadi kanye nephethini: zisakaza amabutho ngendlela engcono kakhulu ezingxenyeni ezibuthakathaka kanye nokubekwa uphawu kwekhanda le-cylinder, ukugwema ingozi yokuguqulwa okungalungile, ukulungiswa okungalungile, ngamafuphi, ukuhlanganisa kabusha okungalungile. Ngivele ngishiye ama-valve ngaphakathi kwebanga le-bilge ngaphandle kokukhuphukela phezulu kwekhanda lesilinda: isembozo sekhanda lesilinda kanye nophawu lwaso. Kuzoba nomdlalo onama-valve, futhi lona kuzophinde kube ngowokuqala kimina.

Ngikhumbule

• I-cylinder head disassembly iyisici esivelele sokwakhiwa kabusha, kodwa ukuhlanganisa kabusha kunzima kakhulu kokubili.
• Ukubuyisela kabusha kudinga ukulungiswa kokusabalalisa
• Ukushiya isivalo sebhodwe sivuliwe kukuvumela ukuthi udlale ama-valve ohlelweni
• Noma iyiphi injini ehlukanisiwe yophawu kuyodingeka ishintshwe kufakwe entsha.
• Noma iyiphi i-crankcase seal ehlakaziwe kuyodingeka ishintshwe kufakwe entsha.

Hhayi ukwenza

• Ukugqokwa kwegeyimu nokusatshalaliswa okunganakiwe
• Sebenzisa kabusha isilinda sekhanda esivele sihlanganisiwe
• Skrola ikhanda lesilinda ukuze uzwe futhi ngendlela engafanele

Amathuluzi

• Ukhiye wesokhethi ne-hex socket,
• i-torque wrench noma i-adaptha ye-torque
