Those of you familiar with the ARB will have seen the holes that they drill for the air passages thru the carrier unit. Then they plug the hole on the outside with what looks like epoxy. Has anyone had problems with these plugs failing?

This problem took us out of Saturday's run at ProRocks this weekend. One of the plugs blew out of the ARB carrier. I welded it up Sat night and they continued on Sunday. Is this a major problem? Should we drill the epoxy out and weld them up to begin with?

What's everyone's thoughts/experiences?

Never heard of that before. I know what you are talking about but never heard of that ever going out. Sounds like it is fixed for good now.

what all did Jason break Sat when he came back hard on the rear end, I heard it lose air, and the rearend looked like it was outta wack!

It snapped the rear control arm, then the arm came up and broke the fitting off the air tank.

Totally seperate from the ARB system. He's using an ARB compressor for the ARB, and an engine diven for onboard air (tools, tires, etc).

So no one has ever had an ARB fail like this?
I guess we were just the lucky ones. :)
It had to happen during competition.... :(

I've wondered about that before, but never seen it as a failure mechanism.

did the threaded screw fall out if so how? and how did you
weld it? because you must have blowwin the screw out?

I saw no sign of threads. I debated on threading in a 4-40 screw, but decided to go ahead and weld it. It's a Toy unit, so I welded it all assembled in the 3rd member. Just cleaned it good and used some 309 SS wire and my TIG. Worked great, totally air tight and minimal heating.

From the lack of responses, it guess this was a fluke deal. I would still be tempted to weld one up new, but probably does not warrent pulling one out..

So did you weld up all the holes or just the one that leaked?

The one that blew out is drilled in from the outside of the carrier, located at one of the recesses for one of the star head bolts used to assemble the ARB carrier. Thats the one I welded.

The other hole is drilled in from the end of the bearing 'snout'. It was not leaking, and I was weary of welding on that because of it's close proximity to the bearing and the ARB air ring (o-rings).

I should have taken pictures, but I was kinda in a hurry. ;)

That probably makes no sense. How about a pic..
