Uma imingcele yanoma yiziphi izingxenye ingahambisani naleyo enikeziwe, ingxenye kufanele ishintshwe futhi ihlanganiswe kabusha.

Ama-valve, njengama-guide bushings, athengiswa kuphela ngamasethi ayisishiyagalombili. Futhi hhayi ize. Lezi zakhi nazo ziyinkimbinkimbi. Akunconywa ukufaka esikhundleni se-valve eyodwa kuphela noma umkhono owodwa.

Ukuxazulula inkinga kwe-valve kwenziwa kusetshenziswa i-micrometer

Inqubo yokushintsha i-valve ukukhipha eyonakele bese ufaka entsha. Abukho ubunzima lapha. Kodwa nge-bushings kufanele ucabange kancane. Basuke efakwe usebenzisa mandrel efanayo ukuthi thina wawakhipha. Kudingeka siphendule ikhanda ngomshini we-valve ubheke kithi. Ngemva kwalokho, umhlahlandlela omusha ufakwa esokhethini, i-mandrel ibekwe onqenqemeni futhi ingxenye igaywe ngesando ize ime.

Ukugaya ikhanda le-cylinder

Ukugaya ikhanda le-cylinder kuyadingeka ukuze kulungiswe i-geometry yayo noma ukuyibuyisela ngemva kokushisela. Ikhanda lingase lilahlekelwe ukuma kwalo uma injini ishisa ngokweqile. Imisebenzi ye-Welding enemifantu, ukugqwala futhi kubangela ushintsho kumingcele evamile yejometri yengxenye. Ingqikithi yokugaya iwukuba izinga eliphezulu lokukhwelana kwayo ngangokunokwenzeka. Lokhu kuyadingeka ukuze uqinisekise ukuxhumana okungcono ne-cylinder block.

Akunakwenzeka ukunquma ngeso ukuthi ikhanda le-cylinder lilahlekelwe ifomu layo le-soy. Kulokhu, amathuluzi akhethekile asetshenziswa. Ngakho-ke, ukugaywa kwekhanda kuvame ukuqhutshwa ekuhlakazweni ngakunye. Ukwenza lokhu ekhaya ngeke kusebenze, ngoba lapha udinga umshini. Akufanele kucatshangelwe iseluleko "sochwepheshe" abathi ikhanda le-cylinder lingafakwa ngesandla ngesondo le-emery. Kungcono ukuphathisa leli bhizinisi kochwepheshe. Ngaphezu kwalokho, umsebenzi onjalo ngeke ubize ngaphezu kwama-ruble angu-500.

Ukufaka i-gasket entsha nokuhlanganisa injini

Lapho zonke izingxenye ezingalungile sezishintshiwe futhi ikhanda le-cylinder lihlanganisiwe, ungaqhubeka nokufakwa kwalo. Lapha kuyadingeka ukukhombisa ukuthi ngokufakwa ngakunye kwekhanda, kungcono ukusebenzisa ama-bolts amasha ukuze aqiniswe, ngoba anwetshiwe. Uma ungenaso isifiso esithile sokuthenga ama-fasteners amasha, ungabi nobuvila kakhulu ukuwakala. Ubude bawo akufanele bube ngaphezu kuka-115,5 mm. Uma noma yimaphi amabhawodi makhulu, kufanele ashintshwe. Uma kungenjalo, ngeke ukwazi "ukwelula" kahle ikhanda le-cylinder. Kunconywa ukucwilisa kokubili amabhawodi amasha namadala emafutheni enjini okungenani isigamu sehora ngaphambi kokufakwa.

Okulandelayo, faka i-gasket entsha hhayi ekhanda, kodwa ku-block. Awekho ama-sealant okudingeka afakwe. Uma ikhanda le-cylinder liphansi, lizobe selivele linikeze ukuqina okufunayo kokuxhumeka. Ngemuva kokufaka ikhanda, sishaya ama-bolts, kodwa noma kunjalo ungawaqinisi ngamandla. Kubalulekile ukunamathela kuhlelo olumisiwe lokuqinisa (esithombeni), nangomzamo othile.

Amabhawodi aqiniswa ngesikrufu se-torque ngamandla athile

Okokuqala, wonke amabhawodi aqiniswa nge-torque engu-20 Nm. Ngaphezu kwalokho, sinyusa amandla ku-70–85,7 Nm. Ngemva kokuphendula wonke amabhawodi amanye angama-90⁰, futhi nge-engeli efanayo. Okokugcina ukuqinisa ibhawodi lokuqiniswa kwangaphandle kwekhanda. I-torque eqinisayo kuyo ingu-30,5–39,0 Nm.

Lapho konke kwenziwa, sihlanganisa injini ngokulandelana kwemiyalelo engenhla. Uma imoto isihambe amakhilomitha ayizinkulungwane ezingu-3-4, ukuqiniswa kwamabhawodi kumele kubhekwe futhi lawo azonwebeka ngokuhamba kwesikhathi aqiniswe.

Ngokwemvelo, noma yimuphi umsebenzi ohlobene nokuhlakazwa kwenjini uyabiza futhi udla isikhathi. Kodwa kunoma yikuphi, ukulungisa iyunithi yamandla kuzoba ishibhile uma uzenzela wena. Ngaphezu kwalokho, lo mkhuba nakanjani uzoba usizo esikhathini esizayo.
