Broken Crankcase???

I was taking off my crankcase cover to replace it after I laid my bike down , and noticed THIS:




Um... I'm not too mechachanically inclined, but I have a feeling this is a bad thing. it's where the coolant goes from the crankcase to the crankcase cover. can I weld the pieces back? I can't afford to get a new crankcase.

I just had my cases apart and can vouch that you do indeed have a broken portion of your lower crankcase. I have seen JB weld work wonders for coolant leaks and holding insignificant pieces of metal together so I say give that a shot. You are right, you can't afford to replace the crankcase, it would be cheaper to buy a motor off of ebay when it is all said and done.

Your best bet is to take the bike to a machine shop and let them advise you on a repair. The case may or may not be weldable and it will require close tollerance drilling to get the O ring to seal properly. If the problem did not involve the O ring, you might give the JB weld a try but in this case,( no pun intended!) I would advise against it.

Thanks. I was freaking out last night when I saw that and thinking the worst. I'll take it in and see what the shop says, but holpfully its not going to take much work.
Maybe i can do it myself with some jb weld and some gasket sealant, depends on what their verdict is... I just really want to get riding again as soon as possible now that all my parts are here and begging me to put them on.

I'm glad this forum is here. its nice to have rc51 guys sharing knowledge with each other - and giving each other shit... always entertaining, especially at work.

That's it, screw the med school fantasy, welding appears to be where the green is. 250 bucks OMFGod!!!! I know aluminum is one of the trickier metals to weld, but damn that is an awful lot of money for a small fix like that. But still cheaper than a motor off of ebay

That's repairable and not too difficult for someone , who can weld Aluminum.

I can top that. My diesel pickup needs new fuel injectors. The dealership estimates $5,000!
I can buy an injector replacement kit online for $350 to $800.
I think I'll do it the myself.

Sounds like an lb7 duramax. I just did mine. If it is you also have to replace the fuel lines that screw into the injector and fuel rail. Also changing the injector cups is not a bad idea. You can get your injectors checked and repaired for less.


Anyway I had a bike split a case where the oil banjo screws in. Had it welded and machined flat again cost around 150$ total.
