Chez Dovinta Heavy Truck & Equipment Service, nous avons r\u00e9cemment effectu\u00e9 une r\u00e9paration et une r\u00e9vision du d\u00e9marreur sur un Western Star 4900 \u00e9quip\u00e9 d\u2019un moteur Detroit Diesel 60 Series.<\/p>\n\n\n\n\n\n\n

\n\n\n\n

Sympt\u00f4mes signal\u00e9s<\/strong><\/p>\n\n\n\n

Le camion pr\u00e9sentait une rotation lente du moteur au d\u00e9marrage. Par temps froid, le probl\u00e8me s\u2019aggravait, n\u00e9cessitant un temps de d\u00e9marrage plus long et exer\u00e7ant une contrainte inutile sur les batteries et le syst\u00e8me \u00e9lectrique.<\/p>\n\n\n\n

\n\n\n\n

Diagnostic<\/strong><\/p>\n\n\n\n

Apr\u00e8s avoir retir\u00e9 et d\u00e9mont\u00e9 le d\u00e9marreur, notre inspection a r\u00e9v\u00e9l\u00e9 les causes principales :<\/p>\n\n\n\n

Des contacts du rotor br\u00fbl\u00e9s et encrass\u00e9s, recouverts de d\u00e9p\u00f4ts de carbone.<\/p>\n\n\n\n

Des contacts de sol\u00e9no\u00efde us\u00e9s, avec des piq\u00fbres visibles qui limitaient le passage correct du courant.<\/p>\n\n\n\n

Ces deux probl\u00e8mes emp\u00eachaient le d\u00e9marreur de fournir toute la puissance n\u00e9cessaire au moteur Detroit Diesel.<\/p>\n\n\n\n

\n\n\n\n

Le processus de r\u00e9vision<\/strong><\/p>\n\n\n\n

Notre \u00e9quipe de service poids lourd a effectu\u00e9 une r\u00e9vision compl\u00e8te du d\u00e9marreur, incluant :<\/p>\n\n\n\n

Reprise du rotor au tour pour restaurer des surfaces de contact lisses et conductrices.<\/p>\n\n\n\n

Entretien et remplacement des contacts du sol\u00e9no\u00efde, garantissant une distribution fiable du courant.<\/p>\n\n\n\n

Inspection d\u00e9taill\u00e9e des enroulements, des isolants et du c\u00e2blage.<\/p>\n\n\n\n

Remontage professionnel avec le couple de serrage et l\u2019alignement appropri\u00e9s.<\/p>\n\n\n\n

(Voir les photos du rotor avant et apr\u00e8s l\u2019usinage.)<\/p>\n\n\n\n

\n\n\n\n

R\u00e9sultats<\/strong><\/p>\n\n\n\n

Une fois r\u00e9install\u00e9, le moteur du Western Star d\u00e9marrait plus rapidement et plus vigoureusement, avec un lancement ferme et fiable \u00e0 chaque tentative. Le conducteur a imm\u00e9diatement constat\u00e9 une am\u00e9lioration des performances et de la fiabilit\u00e9.<\/p>\n\n\n\n
