Nice job on the repair. Just FYI though, on those cases they don't use gaskets on the sealing surfaces as the machined surfaces have to be exact to establish crankshaft endplay. I repaired a lot of cast aluminum cases from powersports equipment (motorcycles, ATVs, snowmobiles, etc.) over the years and it seems no two are the same. Each one presents its own uniqueness, whether it be oil saturation, casting quality, fuel that was run through the engine on two strokes, etc. For the sealing surfaces at the case split, I prefer to use sandpaper on my surface plate and lap the surfaces. I apply bluing to the surface, then lap until everything is 100% flat. Also, have you tried 4943 TIG rod on cast aluminum? If not, can I recommend grabbing a sample and giving it a try. That seems to be my "go-to" now for cast aluminum work. Great job. Mike
Great video. Sometimes you can use a stainless steel bolt to thread into the bolt hole to help with preventing some distortion. And if you have a open bore or thin area next to the bolt hole, it sometimes helps to prevent further opening or blow through. Stainless steel over steel just to help prevent carbon contaminated. You probably already know about this tip anyway lol you do great work. Great video as always. God bless you and your family. God Bless America 🇺🇸
That’s a great suggestion. I never thought to try that, but if I find myself in that situation again, I’ll definitely try it. Thanks for the suggestion, and thank you for watching! God bless you and your family as well!👊🏻🇺🇸
Get use to using 5356 for filling after a small bead of 4043 on the cast. 5356 can't go right to cast but will stick to the 4043. 4043 is gummy and does not machine clean. 5356 machines perfectly with an excellent finish. Filing a hole that does not need to be machined 4043 works fine.
I keep my welder set at 250 amps for the majority of my cast projects, and I use a foot pedal. My AC balance was 70% EN, and frequency was 120 Hz. Thanks for watching!
That’s not a dumb question at all. Sand blasting definitely gives a nice clean part to work with, and there are a lot of situations where I wish the customer would have done it, or that I had that capability, I just don’t right now. Might be a good idea for something for me to look into getting. Thanks for watching!

i do a lot of cast aluminum repair, including machine work. My biggest was a fist size hole thru a boss on a Can-Am cast. Excellent work!
That sounds like a dandy job! Thanks for watching!
Nice work, of a bad hole. 👌 Happy Fathers Day.
Happy Father’s Day and great job on the repair.
Thanks, Happy Father’s Day to you as well! Thanks for watching!
Enjoy watching you weld in your shop. I am using millermatic 210. Also Arccaptain 200 that does spot welding auto panels like a champ. Kentucky
Sounds like you have some nice equipment! Thank you for watching!
That turned out great.
Thank you, and thanks for watching!
Another fine weld. I never would have believed you good fill in an aluminum case like that.
Thank you. Just keep stacking beads till it’s filled up! Thanks for watching!
FYI, some of those cases do NOT use a gasket, only a bit of special case sealer, so a high quality surface finish is important

Thanks Mike. We’re all good in the hood, Lol. Hope you and your crew are all good as well. Happy Father’s day brother!
Bon Boulo😆😆👍👍
PARABENS, SERVIÇO PERFEITO.
DID YOU NOT SEE THAT HUGE CRACK OFF TO THE RIGHT?
AS A MATTER OF FACT I DID, AND IT DOESN’T MAKE A DANG BIT OF DIFFERENCE. ITS JUST A PARTITION WITHIN THE SAME SEALED CHAMBER. THANK YOU FOR WATCHING!
Nice job!. What amps and what was your balance on this weld?
I keep my welder set at 250 amps for the majority of my cast projects, and I use a foot pedal. My AC balance was 70% EN, and frequency was 120 Hz. Thanks for watching!
Dumb question but with the reamers or any of ur work is there a reason to not sandblast?.

What setting you running on tig ?
