    Default Releaser wont get vacuum

    I had trouble with my releaser, 12x12x18x6 model 12-280 lappierre. One side would charge to 26"+ and the other side only to 16" vacuum. I tore it apart and cleaned it with hot soapy water. I was given a care guide from the guy I bought it fro finally. I ordered the right lubricants as I was using a food grade grease called White Gaurd. After cleaning it I threw some olive oil on it just to retry it out of curiosity. Now I have No vacuum at all past the line that enters the manifold with the pistons. I'm having a hard time thinking it's because of lack of grease. Anyone have a diagram of gaskets and such?

    sounds like maybe the 5/16 lines are reversed

    My Lappierre releaser is 12 years old, this season on start up it would not dump, discovered that one of the fitting that the 5/16 tubing attaches to was plugged, new tubing and clean fittings works like brand new, very important that the tubing is hooked back up correctly, they cross each other before hooking to the air cylinder; I always thought that was odd, but that is how they have to be to work properly

    Wasted an hour of my life and an hour of my wifes as well. Can't figure out how to post a pic. Just says file error.

    When you say reverse the 5/16 lines. Mine are probably only 1/4. And then left side to left side of rocker. Center one up over to back side of tee. The lines are not long enough to try any other way in my opinion.

    2 C cup seals replaced. 4 o rings on pvc (2 smaller 2 larger). New ¼ lines. Brass nipples clear. Block removed. Clean and clear.

    Now it charges 1 side but when tripped it leaks thru the three slots on the side that was just charged. I tried adjusting the plunger on the threads. Nothing. Switched end caps and plungers to other sides. No change. Still the same side that will charge and dump but then leak.

    Make sure nothing is blocking the flapper going from the horizontal champer to the vertical one. I've seen Ice build there and make this happen.
