JB Weld

[Texas T]

Went to install some peg lowerers today and when I removed the left side peg bracket I found that the bracket had been fractured at the lower mounting hole, probably when the PO dropped the bike. The peg bolts were only in finger tight and I didn't even have to break them loose with the socket wrench. When I undid the lower bolt the bottom part of the peg bracket just fell to the ground. :eek:

I put some JB Weld Quik on the part and let it set for a little while, but when I tried to bolt it back up the bracket fractured again. I think my mistake was that I coated the outside of the break. I've never used this product before.

So then I made another batch and coated the facing surfaces of the two parts and pressed them together. I'll wait till tomorrow to try to bolt it up again.

I'm not taking any chances so I ordered a new bracket from Ron Ayers tonight.

What experiences have you had with this product and did I just screw up the first time by putting the paste on the outside of the crack?

Should've used JB Weld. If you apply it to a clean surface and let it set up overnight it would be stronger than the aluminum that your fixing.

And yes, the proper way to epoxy something is between the two pieces along the fracture line. Putting it on the outside doesn't give you enough surface area for the epoxy to bite into....

Should've used JB Weld. In retrospect, yes. But I bought the Quik to throw in the saddlebags just in case I needed a fast repair and didn't have four hours to let something set up. Granted, the regular stuff has almost double the tensile strength as the quik but the fracture is a result of the drop so I'm not "too" concerned about its holding properties once it's bolted back in place and I don't drop the bike on the peg.

Hopefully it will hold enough until the new bracket arrives. I can't comprehend not being able to ride for the next week or so! :shock: :mrgreen:

One more question... how thick should this be applied? Goop it on there or just a thin amount?

If you're using the 2-part, quantity doesn't matter as long as you have coated the surface that is being joined. More goop dribbling all over the place is just messy looking, but doesn't add strength. Also, be sure to fully mix the two parts together. When you think you have it mixed, mix it another full minute.

Mmm, I try not use jbweld unless it's an emergency and then only temporarily. I just get the new part if I can.

Just me though, I wasn't always that way.

My experience with JB weld, both quick and reg, has been good when repairing parts where no major stress is going to take place. Major stress, like a footpeg, is likely to be too much for JB.

If it is a part that you are going to experience major stress at, or is a critical part, I'd replace not repair.

I carry some with me also for road repairs b/c it can be a real savior in a jam, but then when I get home I would likely hit bikebandit.com for the part.
