Checking and replacing the Dam Regulator Seat

It's leaking!  Where from?

AIR LEAKING FROM THE AIRPORT

(Following is taken from the Dam Manual)

  • Check the O-ring on the air system. If needed change the O-ring and try again. The O-ring normally used is an 015/70 but some manufacturers might use a different size. Consult the manual of the air system you are using.
  • Replace the #006 O-ring located inside the airport. This can be disassembled using a 3/16" Allen wrench and a 7/16" socket.
  • Check that the hose connector is tight. Use a 7/16” Allen key to tighten. If needed remove and apply thread sealant to the thread and re-tighten. If unsure consult expert advice.
  • Check that the end of the hose is cut straight and is not worn out. If needed cut a small piece off the hose with a razor blade and re-insert hose into the fitting. Make sure hose goes all the way to the end.
AIR LEAKING BETWEEN BODY AND FRAME

(Following is taken from the Dam Manual)

  • Firstly. check that the In-Line Regulator input pressure has not been adjusted too high or too low.
  • The other possibility is that one of the gas passages is leaking. Gas up the DAM without the frame attached and try to locate the exact point of leakage. If the leak is coming from one of the blocked holes remove the screw, apply some thread sealant and re-attach screw to the body.
  • If the leak comes from the small hole on the bottom of the DAM’” body directly below the In-Line Regulator then consult a trained technician before attempting to disassemble the in-line Regulator.
AIR LEAKING FROM BACK OF THE DAM"

(Following is taken from the Dam Manual)

  • Check that the bolt kit is tightened all the way into the DAM“. If the bolt kit is loose, it will start to leak.
  • If the leak is coming from the Back of the regulator you will need to disassemble the regulator and change the #010 O-ring and the seat on the brass seat retainer mounted inside the in-line Regulator.
  • If above does not solve the leak. remove the bolt kit and change the #020 O-ring on the back cap of the bolt. Also change the two 009 O-rings located on the tail of the bolt. Lube well and re-insert the bolt kit into the DAM. Check bolt kit break down for o-ring locations

  • Last. check that the gas passage blocking screw located on the right side of the DAM is not leaking. If the leak is coming from this hole, remove screw and apply thread sealant to it. Make sure to tighten the screw well and wait for sealant to dry (24-48 hours) before re-gassing marker.
AIR LEAKING FROM FRONT OF THE DAM"

(Following is taken from the Dam Manual)

  • Remove the Bolt kit from the marker and change the #017 O-ring located inside of the Can and the #014 O-ring located inside the Manifold. Lube well and re-assemble.
  • If above doesn't help. try changing the #020 O-rings located outside of the Can. Lube well before re-inserting bolt kit.
