ZGOMOT IN ZONA ALTERNATOR


Recommended Posts

e39 - 530i, model 2001 salut. este vorba de un zgomot gros si repetitiv, il veti auzi in upload, distinct, care se aude in zona alternatorului (care este chiar deasupra pompei servo). am inlocuit cureaua de alternator (a 4-a oara) si cureaua de clima, rola intinzator, de ghidaj, rulmentii fata si spate la alternator, zgomotul persista. de mentionat ca daca nu pun curea originala de bmw, cu 2mm mai lunga, nu mai face zgomot (dar ma enerveaza ca aluneca pe role si scartaie pana se incalzeste motorul). sunetul se amplifica odata cu consumatorii porniti, si inclusiv odata cu rotirea usoara a volanului. cei care lucreaza pompe servo in oras au zis clar ca nu este zgomot de pompa servo. la alternator iara am schimbat rulmentii. fulia arborelui cotit nu are nici un fel de problema. am nevoie de ajutor si de idei care sa ma duca la o diagnoza corecta. mersi anticipat! :)
