Default VIR Construction Question

Am I correct in assuming this VIR Air Valve Housing is a press-in fit, or by some chance a screw-in type?



Thanks.
Steve

Not removable, made together. You can change the schrader valve though.

Well.......

That's the problem.



I went to remove the old Schrader Valve, as a new one came with the kit. The old one in there didn't want to come out, like a conventional one that just screws out. It unscrewed but remained held in there. I got a needle nose on it and pulled: some of it came out, some of it remained in there. Now I got a mess on my hands and not sure how to proceed. To trash a whole VIR Top just because of a busted Schrader Valve doesn't sit well with me.

After thought, I could drill and re-tap for a new Schrader valve, but don't these valves require a seat?

Check the local parts store for a combination tool that has an easy-out, tap and die for tire valve stems. The easy-out should get the old piece of the schrader valve out.

This tool works great, have had one for years and it's saved me a few times.

Both tire stems and a/c work.

Thanks for the tip guys. I forgot all about that tool. Everyone out there at the shop has one in their toolbox!

I first screwed the tap side of the tool down in there. Screwed it in pretty hard too, until I could not turn it anymore by hand (fingers). It compressed what valve remanents were in there.

Then I took a 5/32" drill bit and went at it. I then pulled this out.



The old valve part just stuck to the drill bit.



Hole now clear;



..and accepts a new air valve.



Blind luck.

Default Thanks for the help folks.

Next challenge: Engineer this tool to remove the Expansion Valve Capsule so as to clean and replace the O-rings inside. It's really gummed up and somewhat "glued" in place.
