Hello! Let's see if we can work together and come to a satisfactory conclusion!

Expert:  Curtis B. replied 8 months ago.

With the auxiliary system , you have a pressure and return line, and would have to work with a double acting cylinder. Has unit been working, or is this a new application? If you open the two lines from aux, did you have fluid flow in both directions? Is the cylinder on the puller leaking internally? Does it have lock valves n the cylinder? Lock valve may be stuck or restricted, not allowing fluid to flow back to return.??
