Chitani nokha kusintha kwa ma valve ovomerezeka pa Grant
Ndikoyenera kuphunzitsa eni eni omwe ali ndi injini za 16-valve zomwe zaikidwa kuti safunika kusintha ndondomeko ya valve. monga pamitundu yotereyi pali zonyamula ma hydraulic. Ngati muli ndi ochiritsira 8-vavu injini ku Kalina (21114) anaika pa Grant wanu kapena ndi opepuka pisitoni injini, koma mapangidwe omwewo, muyenera kusintha pa zikwi zingapo makilomita.
Kuchuluka kwa ntchitoyi kumadalira kuchuluka kwa makina omwe amafunikira. Mwachitsanzo, pali eni ake ambiri omwe, ngakhale atathamanga makilomita 100, sanakwerepo ndipo zonse zili bwino. Ngati munamva kugogoda pansi pa chivundikiro cha valve, makamaka pa injini yotentha, kapena injini sichiyamba bwino, M'malo mwake, chifukwa chake chikhoza kukhala kusiyana kolakwika pakati pa ochapira ndi onyamula valavu.
M'munsimu muli mndandanda wathunthu wazida zomwe mungafunikire kuti muchite izi:
- Socket mutu kwa 10 ndi wrench kapena ratchet
- Mapiritsi a mphuno zazitali kapena zopalira pochotsa ma washer akale
- chipangizo chosinthira chapadera (timagula VAZ 2108)
- oyendetsa
- Seti ya ma probes kuchokera ku 0,05 mpaka 1 mm.
- kusintha ma washer (ogulidwa mutatha kuyeza kusiyana komwe kulipo)
Kanema pakusintha mavavu pa Grant ndi 8-cl. injini
Kanemayu adajambulidwa ndi ine ndekha ndipo adayikidwa panjira ya YouTube, ngati muli ndi mafunso, lembani ndemanga zomwe zili kale panjira.
Chabwino, m'munsimu mukhoza kuona chirichonse mu mawonekedwe a malipoti chithunzi.
Tsopano tikuwuzani momwe mungachitire komanso momwe mungachitire. Kotero, sitepe yoyamba ndiyo kuchotsa chivundikiro cha valve ku injini, komanso chivundikiro cham'mbali, chomwe chimayendetsa nthawi. Kenako timavumbulutsa makina ogawira gasi molingana ndi zipsera kotero kuti zilembo zapa flywheel zomwe zili ndi chivundikirocho komanso nyenyezi yanthawi yozungulira yomwe chishango chimagwirizana. Werengani zambiri za njirayi apa: Momwe mungakhazikitsire nthawi ndi ma tag.
Kenaka timakweza gudumu lakumanja la galimotoyo kuti likhale loyimitsidwa, kotero kuti kutembenuza crankshaft kudzakhala kosavuta. Kotero, pamene zizindikiro zayikidwa, timayesa kusiyana pakati pa okankhira ndi makamera a camshaft:
Chidziwitso: pa valve yolowera iyenera kukhala 0,20 mm, ndi valve yotulutsa mpweya 0,35 mm. Inde, cholakwika cha 0,05 mm chimaloledwa. Ngati muyeso mipata imasiyana ndi miyeso yoyenera, ndikofunikira kusintha. Pamalo pamene zizindikiro zakhazikitsidwa, ma valve 1,2,3 ndi 5 amasinthidwa. Chifukwa chake, kutembenuza crankshaft kutembenuka kumodzi, zotsalazo zimayendetsedwa.
Kuti tichite izi, timayika chipangizocho pazikhomo za chivundikiro cha valve, monga momwe tawonetsera pachithunzichi, ndikusindikiza choyimira pa valve kuti chikhale pansi:
Ndipo panthawiyi, timalowetsa cholembera chapadera chomwe chimabwera ndi chipangizocho ndikukonzekera pusher pamalo opanikizika:
Kenaka timatenga mphuno zazitali ndikuchotsa chowotcha chosinthira, yang'anani kukula kwake ndipo, malingana ndi kusiyana komwe kukufunika kuchepetsedwa kapena kuwonjezereka, timasankha washer watsopano wofunikira mu makulidwe. Mtengo umodzi ndi ma ruble 30.
Ma valve ena onse amasinthidwa mofanana. Ndipo muyenera kuchita izi pokhapokha ndi injini yozizira, madigiri osachepera 25, komanso bwino 20. Ngati simutsatira ndondomekoyi, ndiye kuti mukhoza kulakwitsa ndipo ntchito yonse idzapita pansi!
