Regulator rebuild?

[Guinness]

My reg needs some work - it's leaking from the backside. There's a large nut, that when I remove it there's a spring under it. Not really a nut, of course, it's kind of a bolt hollowed out in the middle where the spring sits.

I cleaned it all up, and put it back on together, but it's still leaking. When I tightened up the nut, it bottomed right out, which surprised me.

I'll admit I'm being lazy (that, and I've had a few!) A quick search here didn't turn anything up, can someone point me to something to help me rebuild my regulator?

look for a rebuild kit for your make/model of regulator.

It's probably the diaphragm- same thing happened to me. Got a rebuild kit from Rapid's Wholesale.

I'm trying to figure out a part number for my regulator.

From the tag:
Cornelius Mfg Co. Ltd
Rexdale, On
Min. Inlet Press 500#
Primary (0-60)

I wouldn't screw with it. Any decent local welding supply shop will rebuild/fix it for you quite reasonably.

Are you sure there wasn't a fiber, copper or a small "O" ring under the bolt head you for missed on reassembly? Just checking. Most of these bier regulators are "El Cheaps" not in the class or quality of welding regulators like a Harris or Victor. I would bet a LWS would about laugh at many of these regulators vs what they handle. JMO.
