278 Posted December 23, 2008 Report Share Posted December 23, 2008 (edited) So I recently made a post about finding a billet clutch cover, the reason for this was the original owner put some kind of putty on the bottom part of the clutch cover so I assumed it was cracked. I was inspecting it earlier today and found out it wasn't cracked so I decided to grind off the putty to see why he put it there. this is what I found.... amazingly it wasn't cracked but I want to fix this so I can ceramic coat it but it needs to be able to with stand heat so can I weld this up then grind it down to the original shape or can I use JB weld and just sand it down to the original shape if so will the JB weld with stand 400 F degrees? Help me out guys, thanks :beer: Edited December 23, 2008 by 278 Quote Link to comment Share on other sites More sharing options...
blackedout96 Posted December 24, 2008 Report Share Posted December 24, 2008 Not sure about the JB Weld man, I've seen it used in a case repair(not mine) and it didn't hold up at all there. It is dealing with more than just heat there though.... I have a decent clutch cover I was going to throw on ebay, but if you want it so your starting with something fresh let me know, I'll let it go cheap.

Thanks for the offer Im not really looking at buying one yet, I was just really trying to see if I could fix this one so I don't have to buy one later on. Is the clutch cover aluminum or steel... Im pretty sure its aluminum!? Quote Link to comment Share on other sites More sharing options...
Bill Posted December 24, 2008 Report Share Posted December 24, 2008 Yea its aluminum, from what I know JB weld doesn't take extreme heat very well. It will start to separate. Quote Link to comment Share on other sites More sharing options...
2slow350 Posted December 24, 2008 Report Share Posted December 24, 2008 If I were you I would called direct drive or any builder (F.A.S.T., K&t, A&S, etc) to ask what kind of epoxy they use on cases or the lockouts when they were mostly built out of stock clutch covers..

278 Posted December 24, 2008 Author Report Share Posted December 24, 2008 I think what I'm going to do is take it to one of my buddies and have him sand blast the whole thing then fill it in with his welder then just grind the welds down and coat it. It's free so it cant hurt. thanks for the help guys Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted December 24, 2008 Report Share Posted December 24, 2008 hell i had my old stock cover laying around the house i could have given u if this came up a month ago, but i tossed it out before i moved out here. Quote Link to comment Share on other sites More sharing options...
05.Banshee.SE Posted December 24, 2008 Report Share Posted December 24, 2008 JB weld is good up to 500 degress farenheight (constant) and 600 degrees (short period...10 minutes.) I think someone told me they used it somewhere within a car drag motor and it was fine...granted whatever he used it on couldn't be removed any longer! I think exhaust/cat converters/inside the combustion chamber it's not reccommended. But hell, if your friend will do that for free, it sounds a lot more professional, and done the right way.

2001Stroker Posted December 24, 2008 Report Share Posted December 24, 2008 I've repaired a crack in my boat engine block with JB Weld. As long as you clean up the area real good, it will hold, no problem. I can't remember the name of the stuff, but they sell some two part epoxy for repairing cylinder walls in ship engines. It comes in an orange tub, and a black tub. I'll ask my boy that works at the shipyard what it's called. Quote Link to comment Share on other sites More sharing options...
278 Posted December 24, 2008 Author Report Share Posted December 24, 2008 I may just try some JB weld or some kind of high temp epoxy, I'm not to worried about engine heat just the ceramic coating I like to bake on even though you can let the engine heat bake it on for you... I like to bake it on I think it works a little better, but it take 400F degrees for I think and hour or hour and a half so if JB can take that then I might consider that.

What happens to most people that try and use JB weld is they dont prep the area well enough before they apply it. If you sand the area you are going to apply it too them clean it well with carb cleaner or ether it will hold just like you welded it.

278 Posted December 24, 2008 Author Report Share Posted December 24, 2008 Ok thanks guys, Ill give it a try and I'll post some pics of the final project when it's done. :smile: Quote Link to comment Share on other sites More sharing options...
2001Stroker Posted December 25, 2008 Report Share Posted December 25, 2008 well, since you're taking it off, just build it back up with an aluminum mig welder. If you don't have one, I'm sure there's a local company that can do it for you cheap. Just get them to build it up high, and then smooth it out with a 3M wizz wheel on an air die grinder.

278 Posted December 31, 2008 Author Report Share Posted December 31, 2008 I said I'd post pics so here they are, I used the JB weld and it came out great. The lighting was bad so it's making the case have a silver or grey tint, it's black trust me, and it's clear coated so the light is reflecting a little Quote Link to comment Share on other sites More sharing options...
