Broken cooling fin

[msdosp1mp]

Hello all,

I'm still working on getting all the parts to my 550/650 project together, but have run into a problem. One of the cooling fins on the bottom of my cylinder head, close to where the head gasket mates up to the jug, has broken. Its not a large piece, but was wondering if any attempt should be made to weld it back.


Thanks,
William

If it is not broken through the head I see too many bad things that can happen welding that close to a mating surface and for what benefit?

Pretty much, I thing you'd want to know a guy who was an artist with a TIG welder even if you did consider it.

it wont hurt at all. just dress it up with a dremmel type grinder. if you are a perfectionist you could always grind off the same fin on the other side to match

If you want it to look original make a fin out of JB weld. It won't do much for cooling but it will look nice. One fin missing won't do squat temperature wise.

Welding it is just to tough. There is an aluminum brazing rod that you can buy that is great to fix these. All you need is to super clean the aluminum and then you need a propane torch.
