    Posted: 20 hours 38 minutes ago at 6:14pm
What's the best way to repair the air cleaner cups that are retained by a bail (like on the WD and WD-45)?

I have two that have pin holes in them from water. I cleaned them up well and was going to JB Weld them, but I got to thinking that my not hold up well with the bail pulling up on the bottom of the cup and putting pressure on the cup. Then repeat (untension/retension) every time you want to change the oil. I wouldn't think twice about it for a B/C/CA clamp style air cleaner cup that doesn't have any stress on it.

Solder? Braze? Or am I overthinking it and JB weld is just fine?

On the bright side, JB weld will melt out when you heat to braze...Wink

I’d think that if you could get the JB Weld to squeeze out the pin holes that it would hold…
Otherwise you could put some silicone/ gasket maker in them..

Oil resistant RTV silicone on the inside AFTER cleaning the cup well with brake Kleen. Let cure for a couple of days before using.

I'd braze it, but then I like to braze. I wouldn't think it would be hard to find a good used one? Pretty sure I've got a few out in the parts vault and Lon probably has 20-30, if he can find them after the move.

Pretty sure as I think about things there is a WD style cleaner that the main body is damaged but the cup is fine out there. I'd give you the cup, when do you need it? Could bring it to Hutch or possibly ship it?
