7. Ukuvuza kwe-Crankshaft oil seal

Imishini emisha ivamise ukuba nezizathu ezilandelayo:

1. Indawo yokuvula indandatho ye-piston ayihlanganisiwe ngokwezidingo, ukuvuza kweringi ye-piston kubi kakhulu, i-cylindricity ye-cylinder liner iphumile, imbobo ye-shaft eyinhloko kanye ne-cylinder liner hole perpendicularity iphumile kanye nepiston. ukuvulwa kwendandatho kuya ohlangothini olufanayo ngenxa yezizathu ezihlukahlukene, lezi zici zenza inani lokucindezela elingalungile le-crankcase lehle, futhi kubangele ukuvuza kwe-crankshaft oil seal oil. Isixazululo ukushintshwa kwezingxenye ezingafanelekile ngokwezinkinga zangempela bese uzihlanganisa ngokwezidingo.

2. Ubulukhuni bejenali ye-Crankshaft 50_8.os mm bukhulu, bungapholishwa i-crankshaft ukuze ixazululwe.

3. I-Crankshaft oil seal assembly skew, kulokhu kufanele ihlanganiswe kabusha uphawu lwamafutha,

Ukunciphisa; Kwesinye isikhathi ukuhlanganiswa kophawu lukawoyela kungaphakathi kakhulu, futhi ukuvuza kukawoyela we-crankshaft oil seal kuzobangelwa ukuvimba ingxenye yembobo yokubuyisela uwoyela yekhava yeshaft enkulu. Ngakho-ke, lapho kuhlanganiswa, uphawu lwamafutha e-crankshaft kufanele luvezwe ekugcineni kwesembozo sokuphotha esingu-1.5 ~ 2 mm.

Ikhwalithi ye-4 crankshaft seal seal ayilungile, udebe alubushelelezi, aluthambile, kufanele luthathelwe indawo ngophawu lukawoyela olusezingeni elihle. Uma isiphethu se-oil seal singekho noma imodeli ingalungile, isiphethu kufanele sishintshwe ngesikhathi noma uphawu lwamafutha olusha lwemodeli efanayo kufanele lushintshwe.

5. Lapho uhlanganisa uphawu lukawoyela, udebe lwesigxivizo sikawoyela luklwejwa ngonqenqema olungaphambili lokhiye we-flywheel ku-crankshaft, okuzobangela nokuvuza kophawu lwamafutha. Ngakho-ke, lapho ufaka uphawu lukawoyela, ungakwazi ukuqala ujike indlela engukhiye ye-flywheel ye-crankshaft uye endaweni ebheke phezulu, uklwe unqenqema lwangaphambili lukakhiye ngeblade yesaha endala, bese uphakamisa uphawu lukawoyela ngesandla uma isigxivizo sikawoyela se-crankshaft. ibekwe phakathi, ukuze kugwenywe ukuklwejwa udebe lwe-oil seal.

6. Ngaphambi kokuhlanganisa uphawu lwamafutha, i-crank shaft efana ne-50-8.o. Amafutha kujenali ye-mm angabangela nokuvuza kwe-crankshaft oil seal. Ngakho-ke, ngaphambi kokuhlanganisa uphawu lukawoyela we-crankshaft, kufanele siqinisekise ukuthi ijenali ye-crankshaft 50-8.os mm ihlanzekile futhi ayinawo uwoyela.
