Aac Vavle Spring (aac Internals)

[Blood]

Gday,

Ive looked around and cant find

Can someone explain how to access the return spring inside here ?

(this isnt my exact one, took this picture off another site)

Basically i pulled this off my car to clean the valve ect.. and noticed that the tension on the spring wasnt the best.

I am looking at either re-tentioning it, or replacing the spring...............HOW ? -- Because the diaphram doesnt close all the way and i think its causing higher idel (1200-1400 rpm)

I've tried a screwdriver in there to force two bits of the sping apart further... but cant get it enough so i would have to pull it out..

Can someone explain how to remove it ?

Undo the 2 screws holding the cylinder on the RHS of the picture. CAREFULLY remove the cylinder - CAREFULLY because the spring will shoot everything inside across the garage!

Yes tried that, but when I took off the solenoid;;; I could not pull the spring/ plunger/ piston out of the aac device.

Used long nose pliers to no avail,

I was thinking perhaps the other side,

there seems to be some kind of cover and the spring stuff it moulded in there. - it may also just be a sticker,,

can you confirm if I just use more force it will slide out ?

Im right with you on this also. I was considering picking out the brown filler that is in there that seems to hold it all in. I think my spring is also weak and needs replacing. My idle is pretty crap, ECU just doesnt seem to take control of it very well.

I have a lathe. I was even thinking of putting my valve in the lathe and carefully "turning" out the brown stuff.

At the end of the day, it would probably work out faster and easier to get a whole other assembly from a wreckers for ~ $100-150, rather than playing with that one.

I'm all for the DIY route and will try wherever possible to repair parts, but some times you have to just admit defeat haha.

It's probably not coming apart because, as you said, it's VERY DIRTY.

Try spraying some cleaner - Car-b-clean, etc - in there to free it up.

Yep, tried the carby stuff...

Rpm sits around 1300 .. so ill put up with it for now -- in D its about 1000-1100 ..
