[quote="Tx Jim"](reply to post at 04:51:33 12/03/10) [/quote I am watching with great interest now as the dynamics seemed to have changed from what was posted originally, it was said that the boom leaked down and the 1200 lb base pressure needed to lift the boom raised to 2500 lbs which is consistent with what I explained. That scenerio would be consistent with oil leaking by the packing and the diameter of the rod displacing oil into the top of the cylinder which had no return to sump. Now we've gone to a no leakdown situation and a steady 1200 lbs in the base of the cylinder so the info that I and Owen posted on no longer fits. If the original post was correct that the pressure rose as the boom lowered with the engine shut off then a mechanically induced pressure rise is the only possibility. Now that the boom no longer leaks down I will wait and evaluate further as more information is gathered. In the modern Case backhoes it would be considered normal for oil under some pressure to come from the hoses even with the spool not activated, probably from a regen circuit that another poster pointed out. Interesting discussion, keep the info coming. mEl
