How to repair broken engine wing
« on: Sep 19, 2017, 17:15:20 »
Hi All

I have made the rookie mistake (which will never be replicated) of breaking one of my engine wings.

it is a clean break and if there is an appropriate method of sticking it back on it will go un-noticed!

Whats is the best method in doing so please?

I have attached pictures :)

Thank you!

Thanks for that. If I find a good metal worker in your opinion and based on the pictures could this be be fixed like new?

It can be fixed like new with a Tig welder but you're going to need to separate the motor and hand him the jug.......I don't think you will be able to get the torch head in that small space when the motor is all bolted up

I'd just clean the edge and paint it black for the cost of the TIG job and all the work to tear down the motor. one broken fin won't effect the cooling enough.  Now that being said if the motor is tired and needs top end work anyway and you broke the fin starting to tear it down anyway then I'd probably have that welded, or find new jugs depending on the condition of the bore etc on yours. Once that part is black 99% of folks wouldn't see the broken fin anyway.

Thanks guys, that has put my mind at rest.
My Dad who has Lambretta's says he knows a very good welder locally that will charge 30 to do it. I was stripping the engine back to assess it and give it a good clean up and polish anyway so if it can be fixed, filed down neatly and re-sprayed black without noticing the repair then maybe a very lucky outcome!

Would it be best to get the fin attached back on prior to sand blasting or before to get a smooth, clean finish?

Sometimes it's best to just replace it like I did with QuickSteel
You'll need paint though

Yeah this ^^^^


There's a bunch of metal putties available that you could use - we used to use Devcon in the shop to re- mound broke off fins but yes you will need to paint.


Any TIG welder who knows what they are doing will probably want the block separated and totally cleaned before they touch it. There's a chance you can warp the block doing that as well.

By the way the fin that is 2 more down looks like it's been broken and filed back so you may as well fix that one too.
