Kusintha lamba wanthawi pa Volkswagen Golf V GTI

Lero, m'nkhani yathu, m'badwo wachisanu wa hatchbacks zamasewera a Golf GTI udzawonetsedwa. Injini yamphamvu ya 200-horsepower yagalimoto iyi ikupatsani chisangalalo choyendetsa bwino ngati simungayiwala kuyigwiritsa ntchito munthawi yake. Ndipo gawo lofunikira pakukonza ndikusinthira lamba wanthawi. Volkswagen imalimbikitsa kusintha makilomita 150 aliwonse.

Kumbukirani kuti lamba wosweka poyendetsa galimoto angayambitse kuwonongeka kwakukulu kwa injini.

Kuti mugwire bwino ntchito, muyenera kuyimitsa injini ndikuchotsa gudumu lakutsogolo lakumanja.

Choyamba, chotsani njira ya mpweya. Mpweya wa mpweya ndi ma hoses amatuluka munjira yolowera ndikutulutsa mpweya usanafike ku thupi la throttle (muvi wofiira). Mpweya uwu umadutsa mu chubu chotetezedwa ndi wononga 8mm (muvi wabuluu) ndi nyenyezi ya T30 (muvi wobiriwira) ndikulowa kudzera panjira yolumikizira mwachangu (muvi wachikasu).

Ndiye muyenera kuchotsa chitetezo injini. Pali zomangira zinayi za Torx T25 mbali iliyonse (mivi yofiyira) yogwirizira chishango m'malo mwake, chotsani ndikutulutsa thireyi yolumikizirana (mivi yachikasu) pabampa yakutsogolo.

Kenako, muyenera kuchotsa lamba woyendetsa (muvi wachikasu) ndi tensioner (muvi wofiira).

Timachotsa chotchinga chotetezera cha njira yogawa gasi kuti tiwone lamba ndi zida. Kuti muchite izi, masulani zomangira ziwiri za Torx T30 pamwamba pa chivundikiro choteteza.

Chophimbacho chimakwanira bwino, choncho samalani kuti musachiwononge pochichotsa. Pansi pa chitetezo (muvi wofiira) mutha kuwona lamba ndi sprocket (muvi wachikasu).

Timatembenuza mota mpaka notch pa giya (muvi wofiira) ikugwirizana ndi chizindikiro pathupi (muvi wachikasu).

Chidziwitso: Wina adayika gudumu m'malo awiri ndi oyera, koma tiyenera kuwona notch mugiya (muvi wofiyira).

Mutha kutembenuza injini molunjika potembenuza mtedza wa 19mm pa crankshaft.

Chotsani crankshaft pulley. Mukugwira bawuti yapakati ya 19mm (muvi wofiyira), chotsani mabawuti asanu ndi limodzi a 6mm hex pa pulley (muvi wachikasu).

Pulley ya crankshaft ili ndi bowo la pini (muvi wofiyira) womwe umalumikizana ndi pini ya crankshaft (muvi wachikasu), kotero ukhoza kukhazikitsidwa pamalo amodzi.

Timamasula zomangira zisanu za Torx T30 kuchokera pachivundikiro chapansi cha lamba wanthawi. Sitingathe kuchotsa chivundikirocho chifukwa tikufunika kuchotsa zoyikira injini kaye.

Kenako muyenera kusuntha thanki yokulitsa kuti mupeze mwayi wolowera injini. Ngati simukuwopa kutaya zoziziritsa kukhosi, ndiye kuti simuyenera kuzikhetsa kuchokera m'madzi ozizira; Lumikizani ndodo yaying'ono (muvi wobiriwira), chotsani sensa (muvi wachikasu) ndikumasula zomangira ziwiri za Torx T25 (mivi yofiira) ndikuchotsa chosungiracho kumbali, ndikuchigwira molunjika kuti chisatayike. Ngati mukuwopa kuti choziziritsira chitayike, chotsani payipi pansi ndikuchotsa choziziritsira pankhokwe. Masitepe ena onse ndi ofanana ndi oyamba.

Pogwiritsa ntchito wrench 10, chotsani chosungira chamagetsi.

Kuti ntchitoyo ichitike, muyenera kuyika zoyimira pansi pa injini. Kuti mugawane kulemera kwa injini, bolodi kapena plywood wandiweyani amatha kuyikidwa pakati pa skid ndi chimango.

Timamasula mabawuti awiri a 13mm omwe amasunga bulaketi pakati pa gudumu ndi chokwera chamoto. Timamvetsetsa maziko.

Chotsani pulagi pansi pa gudumu lakumanja ndikumasula bolt 18mm pansi pake.

Pogwiritsa ntchito socket wrench ya 18mm, chotsani bawuti yapansi ya injini (muvi wofiyira). Muvi wachikasu umawonetsa bowo paphiko kuti muchotse bawuti yachiwiri.

Kenako, masulani zomangira ziwiri za 18mm.

Timamasula zomangira ziwiri za 16 mm zomwe zimateteza phirilo ku chimango.

Chotsani m'galimoto gawo la chimango chothandizira injini.

Pogwiritsa ntchito jack, jakani injini kuti mupeze chilolezo chokwanira kuti mulowetse bawuti yomaliza ya 18mm.

Bawutiyo ndi yayitali kotero payenera kukhala malo okwanira kuyitulutsa.

Chotsani chokwezera injini mgalimoto. Zimakwanira bwino kotero muyenera kumasula kuti muchotse.

Tsopano timasula zomangira ziwiri zomaliza za Torx T30 zomwe zimagwira chivundikiro cha lamba wanthawi yochepa.

Chotsani chophimba cha lamba wanthawi yochepa.

Tsopano tili ndi mwayi wofikira kutsogolo konse kwa injini. Pogwiritsa ntchito socket wrench ya 19mm (muvi wofiyira), tembenuzirani injini molunjika ndikuwonetsetsa kuti chizindikiro pa sprocket (muvi wachikasu) chikugwirizana ndi chizindikiro pamutu (muvi wobiriwira).

Ndi lamba wanthawi, pangani zizindikiro zingapo pa sprocket ndi crankcase.

Ndimapanga 2-3 kuti ndiwone ngati mukugwira ntchito pamwamba kapena pansi pa injini (mivi yofiira ndi yachikasu).

Tsopano zonse zitachotsedwa, timatha kupeza zigawo zonse za kutsogolo kwa injini: camshaft sprocket (muvi wofiirira), lamba (muvi wofiira), odzigudubuza (mivi yachikasu), crankshaft (muvi wabuluu) ndi mpope wamadzi (muvi wobiriwira).

Kuti muchotse lamba, masulani mtedza wa 13mm (muvi wofiyira) pa chomangira kenako gwiritsani ntchito wrench 8 kuti mutembenuzire chomangiracho molunjika mpaka lambayo atamasuka.

Choyamba chotsani lamba wa mpope.

Pambuyo pake, chotsani ku mbali zachitsulo za injini.

Kuyika kuli motsatira dongosolo. Nthawi zonse ikani lamba pa crankshaft pulley komaliza. Mukayika lamba watsopano, tembenuzirani chomangira kolowera (muvi wofiyira, molunjika) mpaka notch igwirizane ndi tabu (mivi yobiriwira) ndikumangitsa mtedza wa 13mm. Pogwiritsa ntchito socket wrench ya 19mm, tembenuzani injini 2 mozungulira mozungulira ndi dzanja. Zizindikiro pa sprocket, mutu ndi zizindikiro zomwe tinapanga ziyenera kukhala pamzere womwewo. Ngati sizikufanana, ndiye kuti mwalakwitsa kwinakwake, chotsani lamba ndikuyesanso mpaka zonse zikugwirizana bwino.
