JaseGill Posted October 28, 2014 Share Posted October 28, 2014 Hi all, I have an Iwata TR1 Airbrush and after a recent deep clean (dismantle) it pulses. Diffcult to explain but its a fast pulse as if it takes time to build pressure then lets go but in very short fast bursts. On low trigger setting the cup also bubbles. This is with water as I usually use water to test before use. I'm guessing its the nozzle tip as I have changed the needle, the packing screw O-ring and the PTFE washer (which I had as spares in the stash). I am wondering if the Packing Screw is too tight/too loose. Does anyone have any pointers in troubleshooting it? I have ordered a new nozzle tip and nozzle cap just in case. Thanks in advance, J.

JaseGill Posted November 6, 2014 Author Share Posted November 6, 2014 Fixed it. Just in case anyone else has this issue it was a loose nozzle. The new tool I bought doesn't do it up as tight as the old. Doh! Back to the old spanner that comes with the brush. 1 Link to comment Share on other sites More sharing options...
RalphSarc Posted November 9, 2014 Share Posted November 9, 2014 Yea I was going to say backflow/bubbles in the cup is indicative of a leaking O ring or something not tight! Be careful changing the nozzle tip on a Iwata as they are easily crushed!! 1 Link to comment Share on other sites More sharing options...
Administrators James H Posted November 9, 2014 Administrators Share Posted November 9, 2014 Always make sure you clean the crap out from the joint between the crown cap and the section behind it. If you don't get a good mechanical and crap free joint there, you can have impaired performance. 2 Link to comment Share on other sites More sharing options...
JaseGill Posted November 9, 2014 Author Share Posted November 9, 2014 It was a combo of that and the not so great new Iwata nozzle tool (the red one like a barrel). It cant tighten the nozzle enough to get a good seal so I'm back to the spanner that came with it. I knew it was a dodgy seal just after 3 cleans, rebuilds, new nozzle, needle, packing washer and packing seal I was at my wits end All good now, just need to find some time to go "play" with it Link to comment Share on other sites More sharing options...

JaseGill Posted November 11, 2014 Author Share Posted November 11, 2014 Its not great. very good at removing it without damaging it and putting it back on loosely though so not all bad.. As far as tightening it up it doesn't give the same "feel" as the spanner that comes with the Airbrush. Link to comment Share on other sites More sharing options...
