Does the marker still leak if you cock the marker? ------------- "When I grow up I want to marry a rich man and live in a condor next to the beach" -- My 7yr old daughter. |

Doesnt the bolt reset? If you shoot it and the bolt sticks forward, that is another problem. Most likely caused from overtightening the reciever screws. They only need to be finger tight. Try unscrewing everything and starting over. ------------- "When I grow up I want to marry a rich man and live in a condor next to the beach" -- My 7yr old daughter. |

Ok! just assembled the a5 and I spoke with someone earlier, at a tippmann repair shop and he said that the little plunger that the hammer hits, a lot of times it leaks or it's deeply scratched thought I let u know and after tinkering with it and I had my tank filled it's working just fine now. |

its always possible that you overdid it on the polishing.

| Found out what it was? It was not having enough air in the tank it was at 0 psi, I'm pretty sure it wasen't the polishing I went to a machineist school for 2.5 yrs, so I was very carefull and sorry if I sound rude but I was told the same thing at all 3 paintball stores that I have in my home town thanks anyway. |

I'm having the same problem now. I just finished putting it back together perfectly I thought, making sure the tombstone went in nicely and that o-ring stayed put. It still leaks! I don't know how to fix it, it's put together properly and it's brand new there's no scratches or anything for a leak. It only did this after I took it apart and put it back together but I've checked so many times and everything is in place. I've run out of air to test to see if I fix the leak or not, so I'm not sure what to do now. |

| I think it's leaking from around the front. |

Ok well this is what I was told at the paintball store where I bought my marker, inside the power tube pull the inside valve out dissassemble it, check and make sure that the little valves rubber portion of it is not scratched if it is you can purchase the little valve or the whole thing thats complete and ready to install after lubing. and if it's not clean relube and put it together. |

I fixed it. I watched the video on youtube called A5 Troubleshooting Air Leaks, and I learned that you have to put the tombstone in WITH it's pushpin before you put the end cap on and all that. I never put the push pin in until later, so even though I did everything else right, without the push pin the tombstone had a little room to move and it allowed the o-ring to come loose. |

| the tombstone on an a5 will leak air if your tank is low on pressure. spring, washer, o ring, tombstone._popupControl(); |

| I'm having a problem with my A5 leaking air. I tried the obvious fixes including cleaning and reoiling and checking the power tube all of wich did not fix it... Any ideas??? |

Where is the leak coming from, and how much pressure is in your air tank. I'll be online tommorow aound noon. |

It sounds like it comes from the valve but I can't find any reason for it...
I use co2 and Im not sure how much pressure I have but normally when the can is full and it seals itself as the tank gets emptyer |

| so is that a design flaw with the hammer valve or just 'user-error' putting it back into place? |
Posted By: weiss_1172

| It does look like it is a design flaw, but if anything scrathes that valve it needs to be replaced at least thats what I was told, the only thing that I can suggest is that be very carefull when reassembling. It can be user error when assembling the hammer can hit the valve when trying to slide all the pieces together, what i can suggest is when you slide everything out take the whole gun appart it just makes assembly that much easier and you don't pop the valve apart when going back together. |

| I personaly didn't take the gun apart but when we did after about an hour of use it sealed itself and then works fine but untill then I can hear a hiss when I put my head by the cyclone feed |

| You may still need to take the power tube out and remove the valve out and dissassemble the valve body, and check and see if the rubber on the inner valve is not scratched. |

| if you go to tippmannpros.com and click on the upgrade button scroll down to tippmann and then scroll down to tippmann again go to the second page scroll down to the last picture and you will see a picture of the plunger valve if the rubber part is damaged in any way you will need to replace it. |

Taking apart a valve is not something I would necessarily recommend for a new player. It is rare that the o-rings or seals inside the valve go bad. I have had several A-5's that were 5+ years old, and none of them leaked. More than likely leaks are attributable to bad tombstone o-rings, bolt resting on the valve pin (you should cock the marker prior to airing up), dirt or other debri in the marker, lack of oil, or low air causing the bolt not to reset and again pushing against the valve pin. There is no design flaw in the A5 that causes leaks. ------------- "When I grow up I want to marry a rich man and live in a condor next to the beach" -- My 7yr old daughter. |

| Well I'm fairly new to the sport I've owned my A5 for only 2 months and that same day I took the whole thing apart I stripped it down to bare metal and plastic parts, but thats me. I polished my a5 3 weeks after I bought it and thats when I had my leaking problem and thats when I was pounding the pavement to get some answers and all it was for me at least it was my air tank that was low on air. |

Disassembling the marker and learning the parts is always a good idea and I recommend it to every marker owner. You can't fix it, if you don't know how it works. The exception to this is taking apart the valve. Unless it's leaking or causing problems, there is really no need to ever take it apart. The seals rarely go bad in my experience and there is more chance of mucking it up than doing any good. When it comes to the valve, if it isn't broke, don't fix it. As for polishing the internals, other than making it look pretty, I have seen no real evidence that this really improves performance either. Again, just another opportunity to screw something up if you don't know what you're doing.
Regardless, glad you were able to solve your issue. ------------- "When I grow up I want to marry a rich man and live in a condor next to the beach" -- My 7yr old daughter. |
