    Ok muchachos. Nige, gracias por la traducción, no quería hacerlo antes porque recuerdo haber leído en el reglamento que el idioma era inglés. Entonces tú dices iso 46.

    How are you guys doing? I wanted to inform you that after reading the manual for a while, it occurred to me to change the filter to the hpcu. I had a 1r0741 filter on, replace it with a donaldson p556064. I had not changed it before because as I said before, the machine worked at the beginning...

    This is start vent spool. Has a concave hole. And if it is free. You can look the other way. so. I want to simplify my question. The hole that is hit in the spool speed-brake drains oil or not? I do not know if I should drill there or not? I do not know if it's really a hole or a plug? Or...

    okay. Now my question With the change of the springs in the main valve body, and the machine has not re-ventilated. But here is the doubt. Now the fault has mutated.

    cmark ok. I will keep it in mind. I ask the question again. you think the load pressure drop is by improper adjustment of this valve? or they have nothing to do with the low pressure load?
