Damaged crankcase with pictures -- FIXED

As did mine, the casting broke where the length of the bolt finished. You can see 4 more thread depth which is still good. A longer bolt which is 4 threads more or piece of mind tap a few more threads and it will work.

pretty sure those castings are a aloominum / magnesium alloy . I have a friend who specialises in welding and repairs to engine cases . It can be done , and 're machined so youse never know it had happened The big but here tho , is that the engine would have to be stripped to bare cases to do it . He himself would advise you to look for a set of cases on eBay . If you don't sleep for a couple of nights and devote your days to clever ideas , I'm pretty sure you will eventually come up with a brilliant plan ! It really pains me to read this , as it is exactly the kind of mistake I would make . why are the simplest **** ups to make , usually the most devastating?

It's life! It's why we men men get married !!

Aluminum/ magnesium alloy can be welded. Do not believe this is a cast of that nature. The alloy that you speak of has a much finer grain. Could be wrong but appears to be a low quality cast aluminum. Which would explain issues in the past with blocks that developed leaks. Yamaha used a lot of Magnesium alloys on their cases and covers. Very easy to repair. Welds up nice with the right rod and can be machined. Honda's the same. Might add not only a certified military spec welder but have a two year degree in metallurgy along with a mil spec for certified weld inspector. Not your average welder. Certified in mil specs for the following Aluminum, stainless, Copper, Brass, Magnesium, Titanium, Mild Steel and cast aluminum. You fly hopefully your plane does not have a part that i welded up on a Monday with a hang over. Do commercial aircraft to.

yea but getting married takes weeks of planning and even more weeks to realise you ain't getting laid very often if you don't? it only takes one little oversight to leave a side stand down when trailering ! That said , one little oversight could end up getting yourself married ! Yea I'd have to agree with you there Grumpy .

Paddy O if you are interested I have decided to sell my Rivco Center Stand. Send me a PM.



Edit: Oh You have a Touring. I do not know if it will fit on a Touring.

I have done weld repairs on the sumps.It might weld ok as far as weld ability goes.

You know a few folks on here have made a few comments that make me laugh. Let me share a bit of my background with these folks. Got out of navy in 1999. After a short time as a heavy equipment operator and starved to death due to lack of work because of the weather applied at the local vo-tech for enrollment. Due to the fact that it was two days before classes started did not have a lot of lot of options. Physical therapist or welding course. Counselor and i decided Physical therapist was not going to work out for me. Took the welding course. After two months applied at a F.A.A. Repair station and passed the full penetration stainless steel test as set by the military weld specs. Never looked back. Just forward. Worked my way and do mean worked my way up the ladder. Sumps and engine blocks are no competition at my level. Took it a bit farther by getting a degree in metallurgy so i could acquire a military spec as a weld inspector. I weld both commercial and military aircraft parts for a living and have done so for the last twenty years. Key word here is flight critical parts. Now days live rather well. Paid of the mortgage about 15 years ago. Two pickup trucks 4 wheel drive types paid for. one fiat bought cash out right. Modifications paid for in cash. Harley and S%S engine cash. Rocket X has been paid for about two years running. learned a long time ago Knowledge and ability is what gets your rear end ahead of the game. Not talk. Know a lot of pipe welders that wish they had my skills and ability. Work in a air condition shop and sit most of the time while welding in a very comfortable chair. Got it that way after a lot of hard work. Anytime any place lets drop the hood. The bull**** stops when the hood is dropped. (SMC retired)

Thing is, I'm sure any asshat could make the broken bit stick in place.

BUT

Is it going to be up to bearing a load?
Is it going to crack when you try to tap it?
What is the work going to do to the strength of the case around it?

There is a high likelihood that even trying is going to cause more damage than current.

When an aircraft welder (read: aluminum welding expert) tells you it ain't gonna fly, perhaps...listen...
