Topic: damaged cooling fins

[ianmck]

I have got a couple of slight chips on three of the engine cooling fins, does anybody have any good ways of repairing them, the engine is out but I dont want to strip it if possible.

[Bob Wessner]

I used an epoxy clay to replace a chunk out of the very top fin on my 750. That was about 6 years ago and it's still there, no problems.

Bob I know it has been a long time but do you recall the brand name? Is it the kind with two colors you knead together?

[Bob Wessner]

I do recall that. it was a method to let you know you had kneaded the parts together uniformly. Wish I could recall the specific product, sorry.

[Bob Wessner]

I thought this had come up before and did some searching, here is the product I used and the thread.

Use a 4043 rod and TIG weld them back up

KGOHST is right.
 It is the best method.  Not for a beginner though.

I have a welder shop here who regularly "draws" them back onto engines I get with broken and missing fins. It is just elbow grease with a file to shape them to match the others afterward.

If they are not to bad just file them down. My 750 engine had some broken fins. I spent about 2 1/2 hours and filed them down. It's been awhile now and I can't tell where they are at.  You can blend them in pretty good

Thanks for all you help, much appreciated, Ian.
