Cracked engine case - 2002

Mogly406 · Mar 30, 2007

Hello,
I have an early 2002 FE400e and I just finished splitting the cases for an engine inspection. After searching through many previous posts here, I knew to look for a crack near the swingarm pivot. Well, I found one. At the moment, it is very small hairline crack that is pretty hard to see. I figured though that I might as well have it welded since the engine is split and now is the time to do it. I am going to try and bring it by a welder this weekend. Can anyone post or PM me a photo of a repair that was done in this area? I read some posts of this area being reinforced when welded & I would like to bring a photo to my welder with some ideas. Thanks.

Le frog has my old bike and it has the weld done. Ask him for a pic.
It was welded while apart b ut it was done from the outlside . I belive the casting near the bearing is a bit thin.

I think frog got eaten by a hungry husaberg... don't know if he'll ever be regurgitated up again...

I just recently purchased a 2002 550FC and it appears that it has a crack in the rear springarm pivot as well. Is this something that needs to be repaired asap?? I've put some jb weld on it and it seems to have stopped the leak quite well. I know it seems alittle getto but its working and you can really tell.

You could try JB weld as anything beats the alternative. You may want to drill stop the crack before it spreads. Also check the swingarm through bolt to make sure it is not seized. I think that is what usually causes the cracking. That and the fact that some of the castings are really thin in that area.

Not to sound dum but how do you exactly drill stop a crack, so that it will not continue to spread??

Drydenad,

It's when you drill a small hole at either end of the crack, to keep it from continuing, before making the repair(with JB Weld, or whatever you're going to use).

thanks,

Yes....drill a very small hole at each end of the crack. Usually you will want to use a hand operated carburetor jet drill or something similar.

as i read this it was exactly what i was thinking berger. you go to the end of the crack, until you're absolutely certain that it isn't where you are about to drill, and so that the crack COMES to your drilled hole.

a 1/8th or 3mm drill should be enough.

This spreads the stress of the crack across the 360 degs. and will stop the crack in most cases. Learned this trick in the navy as a young lad.

Hey Taffy, how did you change your Avatar? I have one from Moab that I would like to use..
