Well, I managed to crack my case right above my sprocket. I tryed Epoxying it, but that didn't work and neither did JB Weld. So my next step is to actually have some one to weld it. Now I am wondering if I would have to split the case and give him half to weld? or could I just get it welded on there, or will it warp something or maybe it will make some kind of gas with the oil being inside. Here's a pic of it

 

Well, the first thing is.....

Has the damage created a leak in the case?

Or is this just for cosmetic purposes?

What is the case made out of? cast iron, pot metal, or aluminum.

If this is just for cosmetic purposes and doesn't affect the ridability of the bike you might want to re-think on what your doing.

Unless you have connections, it could cost you depending on what the going shop rate is in your area.

My banshee has the exact same break and as long as it doesn't affect the riding I'm just going to leave it alone.

I am a welder by trade so I do know some things about this.

If your going to try and get it fixed I would suggest that you tear the engine down and then have it welded. Better not to take any chances.

You don't want to get it done and then find out it might have done something to the internal parts or maybe even the seals.

 

Just leave it. Its a cast. Its hard to weld and will be ugly.

 

I can't just leave it! It leaks like a mother outta that hole! Thx for the replys

 

if its not leaking, leave it

 

Did any of you look at the pic? There is a hole [img]i/expressions/face-icon-small-shocked.gif[/img]

 

OK..... Now that we have that clarified.

Do you still have the pieces that were broken off?

What was mounted in that area that it needed oil?

If you have any luck you might find someone whos got a lot of TIG welding expeareance. They might have half a chance at getting it fixed for ya.

 

Yeah I still have the peice that broke off. Is it hard to weld cast aluminum?

 

wow that looks familiar. look at my pics. i was lucky because mine was caused by a continuous problem of bolts coming out of the rear axle carrier(the top one came off 3 times, the bottom one twice). so we complained about it to the dealer and yamaha was nice enough to replace the case and pay for all the service except 2 hours(because there were 6 days left in the warranty[img]i/expressions/face-icon-small-happy.gif[/img] ) we tried this stuff called aluma-loy, but we could get the case hot enough for it to mend to the case. we tried it on scrap metal and it worked perfect. if we could have gotten the case hot enough it would have mended. u would have to seperate the cases to do that but save costs on a brand new case.

 

You can cover that piece and weld on it, you just have to figure out what the material is.

Is it cast aluminum or cast steel? (i honestly dont know, but its a casting for sure)

It will need to be welded with low heat for sure to not make a huge mess.

i would take it to a local fab shop and ask them to do it, we get guys that come in here all the time with stuff off their bikes and tracotrs and stuff, they get stuff fixed for dirt cheap.
