Nguva yekutsiva Nissan Almera

Nissan Almera kutsiva kwenguva pfupi kunodiwa ega ega zviuru makumi matanhatu emakiromita kana mushure memakore mana (chero anouya pekutanga). Kukurumidza kutsiva bhandi renguva paNissan Almera kunogona kukonzera kuputsika kana kuveura kwemazino, uye izvi, zvakare, zvinogona kutungamira mukukotama kwemavharuvhu, kukuvadzwa kwepiston uye zvigaro. Kazhinji, mavharuvhu mavharuvhu ndiwo kiyi yekudhura kwekugadzirisa injini. Zviri nani kusazviburitsa. Imwe pfungwa inokosha ndiyo pombi, iyo pulley iyo inotendererawo nekuda kwebhanhire renguva. Saka, kana uchitsiva bhandi, zvinogona kuitika kuti iwe uchada kuwedzera kutsiva pombi, iwe unofanirwa kugadzirira izvi.

Uyewo nguva yeNissan Almera, iyo inoratidza zvakajeka pfungwa dzose dzinokosha.

Kuti uende zvakananga kutsiva bhandi, iwe uchafanirwa kuita zvakakomba uye zvinorwadza basa.

1. Bvisa kudzivirira kwesimba remagetsi uye bapiro rerudyi kubva kune injini. Ipapo iyo Almera accessory drive bhandi.
2. Isu tinoisa bhari pakati peimba yeinjini uye subframe kuitira kuti bhuraketi rerudyi rechikamu chesimba risisagone kutsigira huremu hweyuniti. Kuti uite izvi, simudza mota uchishandisa yakafara mounting ndiro. Mushure mezvose, tinofanira kubvisa imwe yeinjini inokwira.
3. Isu tinotora kubva kumabhuraketi ari pachitsigiro chekutsigira, mapaipi ekupa mafuta kune njanji uye nekupa mafuta vapor kune anogamuchira.
4. Uchishandisa musoro we "16", sunungura mabhaudhi matatu uchichengetedza bhuraketi rekutsigira kune chivharo chepamusoro chetiming drive.
5. Uchishandisa chishandiso chimwe chete, sunungura masiruuru maviri anochengetedza bracket kumuviri. (Chenjerai kuti kureba kwakasiyana).
6. Bvisa bhaketi rekurudyi kubva pamagetsi emagetsi.
7. Ne "13" musoro, tinosunungura mabhaudhi matatu uye nzungu mbiri kuchengetedza chivharo chepamusoro chenguva.
8. Mushure mekusunungura bhaudhi rakabata crankshaft pulley, zvinodikanwa kuvhara kutenderera kwe crankshaft. Kuti uite izvi, mubatsiri anofanira kupinza giya rechishanu uye kudzvanya brake pedal. Kana panguva imwechete zvisingakwanisi kusunungura pulley mounting bolt nekuda kwekutenderera kwe crankshaft, ipapo shaft inofanira kuvharwa. Kuti uwane iyo flywheel ring giya, iyo crankshaft chinzvimbo sensor inofanira kubviswa.
9. Kuti uite izvi, sunungura zviputi zviviri ne "10" musoro uye bvisa sensor.
10. Isu tinopinza nepahwindo mudzimba dzeclutch pakati pemazino eiyo flywheel ring giya blade inokwira yakagadzirirwa kutanga injini neanotangira.

Nemusoro we "18", tinosunungura sikururu takabata dhiraivha yekuwedzera. Tinoburitsa kiya.

Bvisa accessory drive pulley. Zvadaro tinobvisa zvivharo zvepurasitiki kubva kuNissan Almera nguva yebhandi reimba.

Nehurombo, paNissan Almera injini, hapana yakakosha nguva mamaki pane crankshaft uye camshaft pulleys. Kuti urege kushandura nguva yevhavha, usati wabvisa bhanhire renguva, zvakakosha kuisa crankshaft uye camshafts muTDC (yepamusoro yakafa pakati) nzvimbo yekumanikidzika kwesimbi yekutanga cylinder.

Kuti uone nzvimbo ye camshafts, zvinodikanwa kubvisa maviri erubha uye simbi plugs kubva kumakomba ari kuruboshwe kumucheto we cylinder musoro.

Bvisa resonator kubva munzira yemhepo. Pakati pepuragi (rubber matrix), tinochera gomba ne screwdriver. Uchishandisa screwdriver serevheti, bvisa plug kubva pahumburumbira musoro gomba. Bvisa imwe plug nenzira imwechete. Chinhu chikuru usati watsiva bhanhire hakusi kukanganwa kutenga spark plugs kutsiva iyo yakakuvadzwa.

Shandura crankshaft wachi nechekure neanobatsira dhiraivha pulley bolt kudzamara magonhi ari kumagumo ecamshaft atora nzvimbo yakachinjika (inowanikwa pakatarisana nendege yebutiro uye cylinder head connector) uye inotamiswa pasi inoenderana nemasanhu ecamshafts.

Kugadzirisa camshafts paunenge uchitsiva bhanhire kubva kune ndiro yesimbi nehupamhi hwe 5 mm, zvakakosha kuita chigadziro chehumwe hukuru (ona mufananidzo uri pasi apa).

Isu tinoisa chishongedzo mumagrooves eNissan Almera injini camshafts.

Kuti utarise kuti crankshaft iri munzvimbo yeTDC yepiston 1 uye 4 yemasilinda, gomba rine tambo yeM10 rinopihwa mucylinder block, umo mune yakakosha pini yekuwana ine shinda 75 mm kureba inoiswa. Kana crankshaft iri munzvimbo yeTDC yemapistoni eiyo 1st uye 4th silinda, chigunwe chinofanirwa kuzorora pakatarisana neyakagayiwa lining padama re crankshaft uye kuvhara shaft paunenge uchiedza kuitenderedza wachi.

Tichishandisa musoro we "E-14", tinosunungura puragi yetekinoroji kubva pagomba rakarukwa muvharovha iri kumberi kwechivharo, mudunhu rekutanga silinda, pazasi peoiri yekumanikidza alarm sensor (injini inoratidzwa. mumufananidzo wakabviswa kuti ujekeswe).

Sepini yekugadzirisa, bhaudhi ine tambo yeM10 uye kureba kweanenge 100 mm inogona kushandiswa. Tinoputira maviri M10 nzungu pabhaudhi uye tinovhara kuitira kuti kureba kwechikamu chakarukwa chinyatsoita 75 mm. Yakagadzirwa chishongedzo: Isu tinokurisa pini inokwirisa mugomba rakarukwa muhumburumbira.

Kana crankshaft iri munzvimbo yeTDC yemapistoni ekutanga uye 1th silinda, pini yekutsvaga (4) inopindirwa mugomba kusvika kumagumo eshinda yayo uye inomira pakatarisana neyakagayiwa lining (1) pa crankshaft web (ye kujeka, mufananidzo unoratidzwa pane injini yakabviswa uye nemafuta pani yakabviswa). Muchiitiko ichi, crankshaft haifanirwe kushandurwa newachi.

Kana, kana iwe uchikwenya mupini inokwira, iwe unonzwa kuti yanamira, uye kupera kwenati papini kusingabati kumagumo kwebhegi regomba mu cylinder block (pachava nemukaha pakati pe nut. uye lug), wobva watendeutsa crankshaft inopesana newachi zvishoma kuti uise bhaudhi inokwirisa pulley. Zvadaro tinopinza pini yekugadzirisa mugomba muvharo kusvikira yamira (kusvikira magumo epini nati uye mukuru wegomba muvharo rekubata) uye shandura crankshaft newachi kusvikira shaft lining yamira mupini.

Mushure mekusunungura tensioner inokwirisa nati ne "13" kiyi, shandura roller counterclockwise, kuderedza tension yebhandi renguva.

Isu tinobvisa bhanhire kubva kune tensioner roller uye ipapo kubva pamvura pombi pulleys, crankshaft uye camshafts. Bhandi renguva reAlmera rine mazino zana nemakumi matatu nerimwe uye rakafara 131 mm.

Paunenge uchitsiva bhandi, tensioner uye tensioner inofanirawo kuchinjwa. Isu tinosunungura nati inobata tensioner uye kuibvisa. Uchishandisa Torx T-50 wrench, bvisa screw yakabata cam roller. Bvisa idler roller uye roller bushing. Isa iyo itsva cam roller mune reverse order.

Paunenge uchiisa bhandi idzva renguva nemiseve, ritarise kuitira kuti miseve ienderane negwara rekufamba kwebhandi (wachi).

Isu tinoisa bhandi pamapulleys ane mazino e crankshaft, pombi inotonhorera uye camshaft pulleys.

Zvadaro, panguva imwe chete, tinoisa bhanhire pane tension roller uye tinoisa chigadziro pane stud yepombi inotonhorera. Pakuisa tensioner, isa panoperera bhuraketi mugomba repombi inotonhodza.

Isu tinotora pini yekugadzirisa kubva mugomba mune cylinder block. Isu tinobvisa ndiro kubva kune grooves ye camshafts. Isu tinotenderedza crankshaft kaviri kumberi kuburikidza nescrew takabata yekubatsira dhiraivha pulley kudzamara grooves kumagumo ecamshafts mechi.

Isu tinopinza pini yekugadzirisa mugomba mune cylinder block kuti titarise kuisirwa kwakaringana kwe crankshaft munzvimbo yeTDC yemasilinda 1 ° - 4 °. Dzorera bhandi renguva kana zvichidikanwa.

Isu tinosunungura pini inokwirisa kubva mugomba mune cylinder block uye kuisa screw plug munzvimbo yayo. Isa zvikamu zvakabviswa mune reverse order.

Nekuvhuvhuta kwakareruka kwesando ine mupfuri wepurasitiki, tinodzvanya mapulagi matsva mumakomba ari mumusoro wecylinder.

Kuwedzera kuiswa kweinjini kunoitwa mune reverse order. Isu tinotsiva bhoti kuchengetedza iyo yekubatsira dhiraivha pulley neitsva uye toisimbisa ne torque ye30 Nm, mushure mezvo tinoishandura ne80 ± 5 madhigirii.

Nekunetsekana kwebhandi kwakaringana, chiratidzo chinofambiswa chemuchina chinofanirwa kuenderana nenotch yechiratidziro chakamisikidzwa cheiyo tensioner.

Kana museve unofambiswa wakadzimwa kubva pamuseve wakagadzika, hapana kutekenyedza kwakakwana pabhandi. Kufamba kwewachi kuchasimbisa tambo.

Muzviitiko zvose izvi, kusungirirwa kwebhanhire kunofanira kugadziriswa. Sei uchitora kiyi "13" uye usunungure tensioner coupling nut, shandura roller munzira yaunoda ne "6" hexagon, zvino, uchibata hexagon, simbisa roller ne13 key.
