690B relief adjustment

dimanche 31 décembre 2017

Good Morning,

Im back to running our B model more and when curling a tree root it seems like its bogging down too soon. I was thinking of checking relief pressure. On the steel boom cylinder lines there are JIC caps. I was thinking of welding a CAT male quick connect fitting to those caps and watching gauge while in relief. Would this be an acceptable way to test? Are these relief valves preset? Im sure everything is discontinued.

Also, has anyone resealed the swivel manifold? I would like...
