Starter 2108 Hur man gör reparation med egna händer

Starter på VAZ 2108 bil, till den stora ångeren av G8-vinnarna, bryter ganska ofta. Varje gång du går till bilservice under hans uppdelning, är det naturligtvis dumt, och därför det är nödvändigt att lära sig hur man reparerar det här objektet. Om detta vidare i artikeln.

Startaren är en anordning som är avsedd för omvandling av elektrisk energi i mekanisk för att starta motorn. Faktum är att starteren är en likströmsmotor.

Starter VAZ 2108, tecken på funktionsfel

Det finns ett antal tecken på en startfel med bil VAZ 2108:

  1. Startaren vrider inte motorn. Under tändningsnyckelns tur roterar inte ankaret, och retraktorns relä fungerar inte. Efter att ha startat strömmen är startaren inte avstängd. Dessa symptom indikerar som regel misslyckandet av drivrelälindningen.

  2. Startaren vrider långsamt motorn. När du slår på starteren vänder vevaxeln långsamt. Oftast indikerar det ett fel i stärkelsens borstar, grenrör, stator eller förankringslindning.
  3. Startverket fungerar, men vevaxeln roterar inte. I det här fallet är det troligt att problemet med Bendix-startaren.

Varför starter 2108 bryter

Starter är en kortsiktig motor. När det är i gott skick, och batteriet ger en högkvalitativ ström, börjar enheten vara några sekunder. Det är omöjligt att fungera länge, så förare som gillar att "köra" måste startaren överges av en sådan vana och applicera den endast som tillverkare råd.

Som praktik är det ofta nödvändigt att reparera och ersätta starten på VAZ 2108 i de fall där autoägaren starkt överbelastar den eller körs med ett svagt batteri. Dessutom kan starten från starteren associeras med de eller andra problem som beror på funktionsfel i fordonets kraftenhet.

Som påverkar starterprestandan negativt

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

Som regel uppstår problem med starteren på vintern. Vid negativa temperaturer måste han uppleva extremt höga belastningar. Om enheten är gammal vägrar den helt enkelt att fungera, vilket inte är överraskande, eftersom det uppfattar en stor strömbelastning, vilket är 450 ampere. Den här strömmen orsakar den enskilda gemensamma startbrottet, där kontakterna brinner på reläreläet. I det här fallet talar vi om att placera ledningar som är anslutna till statormotorn och "plus" i batteriet.

Varför kontakterna brinner hur man fixar

Det är omöjligt att undvika att bränna kontakter under bilens funktion, eftersom den ständigt passerar genom kraftkedjorna en stor ström. Följaktligen kvarstår endast en utgång - reparera reläet enligt följande schema, för att rengöra kontakterna och därigenom återställa startens prestanda.

Verktyg, armaturer, förbrukningsmaterial

  1. Ommeter.
  2. Figurerad skruvmejsel.

  3. Nyckeln till "10".
  4. Små sandpapper.
  5. Sats av nycklar.

Hur ringer startaren, vilket indikerar behovet av att byta startaren

Implementeringssystemet för denna händelse är väldigt enkelt, det är nödvändigt att sätta ut startlindningarna uppåt, dvs i slutet, varefter vi producerar sådana åtgärder: ena änden av den tråd som vi går med i mekanismbultarna, den andra till den positiva terminalen, starta sedan enheten.

Om mekanismen efter start inte vrider sig alls vänder sig illa, djärvt tar det för reparationen. Men om enheten fungerar normalt betyder det att det inte finns något behov av att demontera det, troligtvis, orsaken till en dålig start består i en annan del av fordonet.

Dessutom kommer det att vara värt att kontrollera mekanismreläet. I denna situation är inspektionssystemet elementärt:

  1. Vi tillämpar "minus" till reläet.
  2. Vi levererar 12-volts spänning till utgången.
  3. Vi ansluter kontaktbultarna.

Om gnistor uppträdde på kontaktbultarna, och kopplingen rör sig in i hålet, vilket innebär att reläet är ordentligt. Bristen på specificerade fenomen och spänningshopp på enheten kommer att indikera att det är nödvändigt att byta ut reläet, eftersom startaren inte vrider på grund av det.

Starter 2108, hur man byter ut det, steg för steginstruktion

  1. Först och främst, koppla loss terminalerna från startaren.

  2. Därefter skruva loss muttern med reläet och demontera ledningsblocket.

  3. Demontera sedan skyddet av motorvevhuset.

  4. Nu skruva vi på startmuttrarna.

  5. Därefter skruva du på den övre mounter monteringsmuttern.

  6. Ta försiktigt bort startaren utåt.

  7. Ny startmontering i omvänd ordning.

Hur man demonterar VAZ 2108 starter, hur man byter borstar, ärmar, ankare

För att demontera starteren, gör följande:

  1. Med hjälp av nyckeln till "10" skruvar vi de två muttrarna i tapparna.
  2. Tillsammans med ankare får vi den enhet du vill ha.
  3. Från trädankaren tar vi bort huvudväxeln.
    004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.
  4. Med en krökt skruvmejsel skruvas vi bort två skruvar från bakluckan.
  5. Ta bort locket.
  6. Ta ut borstarna och ta ett ankare från statoren.
  7. Med ankare, ta bort den speciella justeringsbrickan och axelns uggla.

Nu kommer vi att demontera drivkugghjulen och själva drivkraften, varefter vi separerar stödet från hävarmen för att få tillgång till alla inre starteruppgifter (ankarlindning, penslar och borsthållare, ärm och så vidare). På mekanismens element bör det inte vara spår av charring, och arbetsgrenröret och lindningarna ska alltid vara rena utan olika föroreningar.

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

Om du behöver ändra ärmen. Om det finns små repor på kollektorn, bearbeta dem med liten "sandpapper". Om ankaren brände eller starkt slitna, ändra det till en ny. Om axelagren har loopat eller täppt, bearbeta dem med litet korn. När det gäller borstarna, med sitt slitage, är det nödvändigt att ersätta dem med borsthållaren. Det är värt att notera att deras slitage är synligt omedelbart. Efter alla reparationsaktiviteter utför vi en montering av startaren.

Tips Prof.

Som du ser, reparerar och ersätter startaren - är evenemanget ganska mödosamt, men det är inte svårt. Men om du tvivlar på dina förmågor är det lämpligt att kontakta hundra. Lycka till!
