Problème Défaut Panne hydraulique sur MERLO

pompe rexroth a4v

marc 5 aout 2014
Bonjour,
Le télescopique qui est en panne est un merlo, C’est un circuit load sensing, mon télescopique a un problème hydraulique. pour faire fonctionner le bras ou la flèche de télescopique ou tout composant hydraulique fixé sur le bras, il faut que je tourne le volant même pas d’un quart de tour, et cela fonctionne normalement.

Sur la direction il y a une valve de priorité, j’ai l’impression qu’elle est en panne.
