Re: cracked engine cover

I don't believe I'd try to weld that. A 2 part epoxy like J B Weld would be what I'd use.

Re: cracked engine cover

J. B. Weld is good and should be available in Sydney.

There is another product called Insta-Fix you might want to consider. It is new from Canada and becoming available in the US through HD Supply, I do not know if it is available in Australia yet however I will find out and let you know.

This is the web page http://www.insta-fix.com/

Click on the video and it gives some ideas including fixing a head on a small engine, so you should be able to use it to fix a cracked cover, or anything else.

Forgot to include the obvious. The lawyers will be calling soon.

I've used this stuff or some other form of it several times over the years and it is the permanent repair you are looking for.

Re: cracked engine cover

Personally, I would not weld the cover when replacements are availble from used sources (ebay, ltparts.com, etc.) at reasonable prices.

Thumbs up Re: cracked engine cover

Not a problem welding motorcycle aluminum side covers, I have done it several times using a TIG welder. I am under the impression that the engine covers on the LT are magnesium which to can be welded easily using a TIG welder. But you may be able to repair it without removing it by using JB Weld if the crack is not located near a bolt hole.

--Thats OK I don't care--

Yep, but it TIGs just fine. I don't think I'd take my oxy-cetylene to it.

Come to think of it, just about everything burns at the right temp.
