Roads overhaul of injini, kunyanya mashoko izvo Somuenzaniso, nokuti motokari German akagadzirwa kakawanda kupfuura zvimwe mavanga mota kubereka nyika. Asi usakanganwa kuti nokuda zvokuimba basa rinogona kuva vakadzikama neforogo.

Rakagadzirwa Vaz injini anogona kuitwa panguva garaji, zvakakwana Stock nyore yakatarwa maturusi, pakati vaifanira kuva gasi burner, sezvo pisitoni hoko kune rokumusoro unobatanidza shamhu iri akaiswa imwe tembiricha kuti 750-800 inegumi.

Chokutanga, tinofanira kuziva kuti injini overhaul kunosanganisira rakwo disassembly, saka vachinyatsoziva vanofanira kutarisira kubasa yakachena, basa rokuita nani pane avabvisa injini pasina zvakabatanidzwa. Uyewo, unofanira Stock kukwira yakasimba yakawanda eparafini zvaida "kugeza" nokuti miseve, uyewo mamwe mashoko.

Kana injini yabviswa, zvino basa anofanira muzvikamu zvitatu: humburumbira musoro, chikwata pacharo, uyewo lubrication hurongwa. Uye ikozvino - kuitira uye zvakawanda.

First unofanira kuita zvose zvose, asi zvinokosha kuyeuka kuti vharafu mashandiro usingagoni kutsiviwa, inofanira kuiswa saizvozvo sezvo yakanga. The mavharuvhu, pashure yokutsiva uye yaitsiva mutungamiriri maoko dzinofanira lapped vachishandisa kurovera pastes. The camshaft (kana miseve, kana paine vaviri kana kupfuura) mutengo kunzwisisa micrometer uye kana paine zvarakasiya kubva ndozvakajairwa, kutsiviwa. Zvinokoshawo kuti unyatsoteerera rutsigiro rwavo, sezvo kazhinji Vakaitawo kubva kukandira aruminiyamu (asi nyoro zvinhu kuti ane yakaderera simba).

Zvino zvishoma pamusoro injini chinhu chinogumbura. Pano kugadzira ari chete kutsiviwa. Chokwadi, kana une musha muchini kuchifinha uye honing pamusoro humburumbira, vose basa uchakwanisa kuzadzikisa pachavo, asi vanhu vakadaro vashoma chaizvo. Naizvozvo, chinhu chinogumbura pachakwo kupa mumwe musangano unokosha apo nyanzvi kushanda.

Shure anodzoka, zvichava nasechen pistons mukirasi, izvo zvinofanira kunhonga. Nokuti kirasi imwe neimwe kirasi pisitoni nembambo uye pisitoni zvindori zvaro. yakatarwa kurema nerimwe humburumbira inofanira Zvakanakisa kuva akafanana, asi kukanganisa akabvumira muna 2 magiramu.

Enda mberi. Next pachikwata lubrication hurongwa. injini overhaul uye kugadzira nzira ino, nokuti anokonzera kuchengeteka uye mukurumari wemigove. Pano, zvakare, tinofanira micrometer kuona kana crankshaft magazini kukuya kunodiwa. Kana zvakadaro, tinofanira kuita zvakafanana pamwe chikwata. Kana kwete - unotofanira yokutsiva Mapedhi. saizi kwavo kazhinji zvinoratidzwa yokugadzirisa pamatama pachiyero. Kana pakukura kusingajekeswi, kuti cervix haana yakakweshwa, zvino rinoenderana aizviti ukoshi.

Shure kwema izvi zvose vakaungana, uyewo yaitsiva consumable zvinwiwa, uye firita zvinhu. Pamberi pokutongwa run inokurudzirwa kudira mafuta kupinda mafuta Sefa uye kutsausa pasi crankshaft noruoko. It anotevera kubva zvatakurukura kuti injini overhaul nemaoko avo - hazvina kuipa, nekuti nguva yedu haisi nyore kuwana chero Chinyorwa.
