Question: Hobby

1216874

I have a porter cable roofing gun rn175 it has just started that when you pull the trigger it goes full auto until I unhook the hose. I took the trigger off and just pushed in on the pin at the trigger valve and it still goes auto.
What do I need to fix this?

Hi,
I'm not sure what trigger valve you have .They use two different trigger valves one was a valve that screwed in and the other was a MAX plastic valve that was held in with roll pin.I've never had that problem with a Max valve but the older type valves would wear and allow air to bleed by the port in the valve causing that problem. If you have the older screw in valve you will need to order the o-rings separately and rebuild the valve.Replace your head valve o-rings also while your at it to fix this problem cleanly.Hope that helps.Good luck.

Hi David,

I would suspect the problem is the Check Seal. It is an o-ring around the cylinder that acts as a valve. It commonly will cause the problem you described. The Check Seal is part #886119 and is available from http://www.ereplacementparts.com.

I hope this helps with your repair!

The gun is leaking air around the trigger and at the top of the gun. Do you have a repair suggestion?

Where is the check seal part 127 located at on the cylinder?
Glenn
Reply: Check Seal Location

Glenn

I had the same problem at 1st. Found out that #127 check seal goes over#126 cylinder, right over the small holes on the cylinder. when you pulled it apart #127 catches on#128 cylinder spacer and falls into the bottom. The parts diagram will not show this very good. Try this

Hi Jeremy,

It sounds like you have problems with several different seals in the gun. I would suggest installing the overhaul kit. It will replace all of the o-rings that commonly leak and the trigger valve. It is part #903789 and is available from http://www.ereplacementparts.com.

I hope this helps with your repair!

Hi Keith, Your best bet is to install an overhaul kit, part # 60075. The kit will replace the o-rings and gaskets that most commonly cause air leaks in your gun. The overhaul kit is available here at http://www.ereplacementparts.com. Good luck with your repair! -Mark

Question: Double Firing

Doug

My Porter cable RN 175 roof coil nailer double fires when depressed and I pullback on the trigger.

My gun doesn't have an adjustment on the trigger.

What can I service to rectify this.
UtahAV
Reply: Double Firing

UtahAV

Hi Doug,

I have found that most double firing issues are a result of the gun bouncing when it is fired. You press the gun to the shingle, pull the trigger ans the gun fires. The recoil pushes the gun up just enough to reset the safety. The trigger is still depressed from the first shot as the gun presses against the shingle again and the second nail fires. All of this happens in a fraction of a second. You can test this theory by making a conscious effort to apply downward force to the gun. Use two hands to push down on the gun and see if the problem goes away. If it does it was simply recoil, if not then you will need to dig into the gun. Other causes could be a trigger valve issue, a safety linkage issue or a worn magazine.

I hope this helps,

Question: Stuck Piston

clong1946

I have a porter cable rn175 coil nailer. when you pull the triger the piston fires but it will not return. it stays in the down position. I have installed a rebuild kit part #60075 but this did not help. Also the nailmover piston retracts and slowly moves the next nail into the fireing position.Help please!!

Reply: Stuck Piston

The nail driver not returning could be several things. Check the o-ring around the cylinder which covers little holes.

Check the driver o-ring and make sure it moves freely.

Does the nailer leak air? Plant the nose on a piece of wood and hold it down. Pull trigger and hold. Driver should stay down and you should not have any air leaking. Sometimes when it leaks out the nose you have a bad bumper.

As far as the feeder goes....

Your best bet is to pull out the feed piston and check for chunks of the bumper blocking the air passage. Also check to make sure the piston is straight and that it moves freely.

I have had a few of those that the nose was actually bent. If I loosened up the nose screws about 1/2 turn then then feed piston would retract properly.

Reply: Stuck Piston

EngineerJim

To add the the previous post, you will need to remove the piston cylinder. About 1/3 up there are a series of small holes around the circumfrence of the piston. They are covered by what looks like a wide elastic band. When the piston fires and gets past these holes air is allowed to bleed into the lower pressure chamber. ( the band flares outward acting as a 1 way valve) For the return stroke the pressure in the piston is vented, This leaves the lower chamber charged with compressed air which is what drives the cylinder back up. This air also powers the nail feed cylinder.
So - Check that the holes are not blocked and that the " elastic band" is sealing off these holes to prevent air from leaking back into the piston chamber.
if they are ok then you have a leak in the bumper seal or somewhere else in the lower chamber.
when I took apart this roofing gun the check seal popped out and I am unsure where it goes.Please help.

Hey Casey,
What item # is the check seal ..? Some of these parts are only made to assemble one way and wont work otherwise..kinda of the trial by error way..! Just try to follow the parts breakdown as close as possible..

the # is 127 ,it seems to me that it goes over the holes in the cylinder inbetween the snap ring and the plug towards thed front of the gun but the illusration isn't specific enough to tell.

It does go over the holes with the lip side up..all this does is help diffuse the air when fired..make sure those holes are clear and not filled with gunk..when you reassemble also make sure that you use some air tool oil on the o-ring on the driver assy..hope this helps..
