Fixing a Cracked Motorcycle Engine Case / TS185

[@AuMechanic]

If you want to braze aluminium casing or casting you need to take the seals out and put the case in an oven and get it hot otherwise heat will flow away form the weld so fast the casing never get hot enough for the braze to flow to it. Grind the a chamfer on the edges where you are going to weld to make like a valley for the brazing to flow into and use some solvent to clean it well before welding. Might have been an idea to hold the bit in there with 2 small vise grips or bulldog clamps at each end on to the casing.

[@Hellsong89]

Also if any contact with the oil blast it several times with torch to burn any oil out from the porous since that is one of the main things that mess up alu welds, well as brazing is oil burning gasses constantly puff gasses to weld/braze pool. These engine cases are even worse when it can move oil from other areas into that if its porous enough, so yeah excellent cleaning, remove everything out, heat it several hunder C (borderline melting it) to burn out any oil least on that and surrounding spots, preheat whole thing in oven and then try to weld or braze it.

I wrecked on my Yamaha R6 and when my bike hit the ground it cracked the stator cover and took a chunk out of the motor block just like you were dealing with. I thought it was an all lost cause. This video was exactly what I needed LOL bro your a boss thanks for the video

[@cameronwatkins9056]

Hey man, I just had a similar situation happen with me on my 06 zx6r 636... cracked the stator cover, and part of the case... I’m finding all the info for jb welding vs. having someone tig weld it for me or trying the aluminum brazing. Did you end up using one of these methods and did it work? For how long? Etc. much appreciate any response. Thanks

[@Theogcarlton]

@@cameronwatkins9056 I had the same exact thing Happen to me, how did the JB weld hold up for you??

[@Exit13Boxing]

Same zx6r problem for me

[@about2mount]

Nice effort but I will tell you that that crankcase is not aluminum, it is a pewter and or pewter with a plastic polymer mix. And you are correct J.B. Weld is not the best but if you will sand the paint off and leave a feathered edge about a half inch around the area by slightly grinding it, you can then use baking soda and superglue first to seal the seams in your patch peice. Then go over that with the J.B. Weld. I repaired a RM Suzuki 250 dirt bike and my old Honda Odyssey and both have held over 12 years now. I got the idea of Super Glue and Baking soda from a Music Repair Shop. And it will hold well at 200 degree's F as well. Several videos here on KZbin demonstrate this on boiling water pots and Radiators.

[@eddieg849]

And I thought I was the only one in the world that made everything so complicated when it was supposed to been easy

[@rogerbeginify]

I've used alumiweld similar to what you used but they don't require flux. The trick is to pre heat the entire (clean)part up in an oven or gas grill then use a stainless steel wire brush to finish cleaning the part. Then the brazing should stick.Aluminum dissipates heat too fast to braze without pre heating.

I used jb weld on a f150 transmission housing front face where attaches to flywheel. Worked fine. No problem.

Hey, I'm really enjoying this playlist. I love that you show the good and the bad. With every project, it's always 2 steps forward and 1 step back. I am getting ready to restore a 1965 Yamaha YM1 that was almost in as bad of shape as this one. Not quite, but close. I'm think about putting up a playlist of my own while doing it. I'll probably have to check in with you as I have no idea what I'm doing. Good job. Keep 'em coming

[@oddis188]

If you don't get it tig welded that first piece that you glued on with the bolt hole will crack open when you put back the bolts

[@GoldGuyRides]

I'm gonna tighten all of the other bolts real tight and then just snug that one that I jb welded back into place, so the other bolts will hold it down and the snugged bolt will hold it in place, that is if the jb weld doesn't do anything

[@oddis188]

really... Are you trying to do sone Russian bushcraft shit here? I would go to a welder who knows how to weld aluminium and get it done.. you need to have all the bolts the same tightness otherwise some other bit may crack... Or leak etc

[@GoldGuyRides]

@@oddis188 as I said probably 4 times in this video, this part of the engine sees no oil, it is just a cover for the magneto. It's not a big deal bro, you can spend a fortune to get your engine fixed, but I don't like wasting my money.

[@MOUSEBOWEN]

[@worldcollections2839]

I am not sure if it works well or no .. but i think that it will break again once you knock it in a time

[@Finnegan6674]

You needed to flux both halves and heat the larger section first, the piece in your hand will heat up quick once the other half is hot.

[@blender_unleashed]

Did this end up working

[@deeglock3005]

How did you split the case after it cracked?

[@zach5994]

There are multiple points to screw in some bolts meant incase one of them broke.

[@markolivergalzote379]

Why it failed you have to the wall so it can fixed that no one is shake in welding.

[@blender_unleashed]

Also you could've mig welded it and you need a map torch to get it hot enough, the rest of the aluminum case was pulling all the heat away like a heatsink

[@jameshatfield6814]

Good luck bro. Hope it works

[@colinsharp1314]

Great job mate it's going to be ok

[@FvanBal]

I think that your soldering failed because the loose part moved. If the other responders are right, and the JB-Weld doesn't hold, then please try to attach the piece at one or two points using JB-Weld, and then try soldering it again. Also, try to us the flux on the brazing rod and not on the engine parts... Don't know if that will make any difference, but that's the way your test succeeded...

[@SHSPVR]

No the soldering failed because it cast aluminum and really need be done with tig welder and parts has be really super clean

Hello my name is Hernán and I'm from Argentina. I really like your videos, and although I do not understand the language well, I enjoy them equally. I have a Kawasaki Vulcan 750 from the year 1994, and I need new pistons. I want to ask you a favor, maybe you can help me. Do you know any page that sells them, and ship abroad? I was researching on eBay, but I found nothing. Maybe I'm not doing the search right. I'd like to find the right ones, Kawasaki. Of course, thank you very much for the inconvenience, and sorry for the ceremony. I will follow your channel, I learn a lot. Graquas again, greetings

[@ralphlamoureux266]

Caro Hernan, No pierde valor! For any motorcycle parts, you can first check on websites like Partzilla.com, Bikebandit.com, etc... to be sure about the P/N, and check the prices. Then when you know the P/N you search directly with it on your internet browser. If any person is selling it online and has mentioned the P/N , in your country or anywhere else, you should be able to access his/her offer, and you can compare the prices with the previous websites. I can see Vulcan 750 1994 new Pistons/rings are available and below are their P/N, for US models, I ...guess they are the same for Argentinian models. in case you don't know, O/S means the piston/rings are bigger than STD standard. O/S 1.00 for 1mm bigger, O/S 0.50 for 0.5mm bigger. These O/S are only if you need/have your cylinders enlarged ("re-bored") the same way, by a specialist. if you don't need it STD is P/N 13001-1215 for your pistons and P/N 13008-1077 for the sets of Rings , and you need a quantity of 2 of each of these P/N. Hope it helps!!!!!

What did Nasa use to adhere the tiles to the space shuttle? Carbon fiber??? Glues??? JB Weld is great if you clean the metal thoroughly and "overbuild" the area with JB Weld....in other words..stack and spread out... There are times where you just cannot weld!

[@carlschroeder6811]

NASA used high temperature silicone to adhere the tiles, the differences being, much larger surface area, remains flexible and mostly compression loaded, not under tension, not a good analogy.

[@baddriversofmoosejaw8681]

Too bad a new engine case would cost a bundle, especially an aftermarket part. Oh well. I hope the patches held. Be thankful it's not the 80s and 90s anymore. There would be 2 feet of snow on the ground from November to the end of March and freezing cold. Then it would take until May for the snow to melt and for it to start raining again. Isn't global warming wonderful.

[@livewire..]

You were unable to braze the case because you used a carbon steel brush to clean to the aluminium. You must use a stainless steel brush otherwise the braze will not adhere to the aluminium. I think you should spend some time trying to acquire a good used replacement case as this one is badly messed up. Or better yet find a whole engine. I doubt the TS185 you are working on is worth the effort.
