Cracked case
 

After I replaced my chain it came off as I was riding. It cracked and broke off the brackets the bolts that hold the front sprocket and hydraulic clutch housing. How would you go about repairing this. The clutch will not work because the bolts held everything in position. Lost on what I should do. Any help would be greatly appreciated thank you

A few more photos looking straight on would be good.

Here are more pictures after I pulled it apart. This is a very clean bike with just over 18k on it I hope I can save it. Any suggestions or direction to go would be greatly appreciated thank you.

From where I sit you have a few options:

$ JB Weld;););)
$$ Tig Weld:|:|
$$$ New lower case:shock:

I know what I would do and that would be JB unless you know a talented tig welder. Make sure you clean the surfaces thoroughly and mix the JB well and correctly. On the other hand, It is a good opportunity to get a second block and rebuild an even more kickass motor.

If it comes down to choice there is at lease one forum member than supply most if not all of what you need.

Would you really trust JB Weld on that? I don't know I've just never had the greatest luck with it on anything that mattered... I don't see why it should be a big deal to have tig welded. Just don't take it to some muffler shop. Find something along the lines of a custom car shop that tigs frames and roll cages or custom headers, etc... i.e. someone who knows what they're doing.

The covers on my S4 and CBR are plastic...I'd JB in a sec. the location is the hard part for getting it tigged--that and the contamination from grease makes it difficult to make a decent weld.

...just my 2 rupees of advice.

At today's rates, that's closer to 3 cents, but I get your meaning.

That sucks. I wouldn't JB it. It'll be a long drawn out mess to get the material in place to set up, then it'll end up failing on you. W/ rubber bits in close proximity, welding might not be feasible either. I think you're looking at a new case 1/2.

Upper and lower case are numbered and matched based on crank bore...if you get a lower you need a matched upper.

Can it be repaired? Yes.
WIll you find a local skilled welder to do it? Maybe, will they require the parts to be welded to be clean, oil free, not assembled with oil seals, gaskets in them at or near the are to be welded? Likely. Will that welder want the part to be welded on their bench? Likely.

At some point a $100 set of Ebay cases that you transfer your good motor internals into is a good idea......but alas I could never do JUST that , so add new bearings, rings, cylinder prep, gaskets at least...and well your there so all new radiator hoses

I have looked at the photos , multiple times .. And have to agree on a engine case as A last possible. Yet being that the engine case is a Molded cast of a Metal /aluminum..
Question1 -Do you have all the pieces?
Question2 - Can you braze weld?
Braze welding would be the cheapest process to attempt in fix the issue.
TIG welding the pieces would be the next process.. Professional would be advised

I’m going to try and braze it this weekend. I’ll up date with results. Wish me luck.

Any luck?
