There could still be a couple of different causes for the problem you are having. A constant leak that does not prevent cycling normally indicated either a damaged spool seal or the main valve face seal. The problem is that now we're getting into the area where you need to find that leak and the easiest way to find it is not the safest way. Try this; take out the regulator cap screw, spring and piston out of the regulator cavity. Put the cap screw back in and make sure you leave the regulator sleeve in place (otherwise you'll blow tank pressure straight out the regulator cavity). Now connect your air again. There should be no pressure going to the pneumatics now so if you hear a leak still it can only be from the main valve seal. Now if you have an air leak from the regulator cavity then your poppet seal is damaged.
A very important step is to put that cap screw back in place. There can be a chance with older guns for the sleeve to fail and blow out of the housing, this is very bad and will cause severe injury including possible death. A few years ago I had one blow by my head bounce of the ceiling and break a jar 40 feet away on the other side of the shop. I kid you not, if you are not completely sure of what you are doing don't do it and just send it in.
The procedure I just went through will isolate the leak. This will not correct it, just confirm what is leaking. It may be simplest to send it in for the repair, but I can walk you through some more steps if you would rather go it alone.
If the poppet is leaking this will allow higher pressure than needed to get into the pneumatics and will cause it to leak. |
