As promised I’m making a detailed guide for rebuilding AAV.
First step is to remove thermo bulb.
You can do that by pressing in the other end (air outlet).
Spray decent amount of oil inside the valve to make disassembly easier.
Don’t worry you will not brake anything inside.
Keep pushing till the bulb falls out.
When the bulb falls out, take out the piston and spring and then push the remaining part the other way back.
Theoretically you can just press it back to its previous location, but in this case I’m pressing it all the way out as I want to use different air hole configuration (more info on different air holes will follow)
After full disassembly all parts go to ultrasonic cleaning.
To be continued…
