Case repair

As I had a bit of spare time I thought I'd try and repair a rather knocked about oil spinner cover. I used lumiweld, a low temperature ally repair. Using only a propane blow torch I ran into the damaged areas some of the Lumiweld, I then filed the surplus off and then wet and dry till level and then buffed it up. It's sort of OK, the Lumiweld is a slightly different shade so is visable, particularly the large area but the digs and scrapes look fine.

Nice job. It is great to find out these tips and products that work.

Looks good. I have been thinking of doing the same thing as my oil filter cover also shows signs of riding my bike sideways. I think I'll do it.

BTW, Lumiweld is not the only supplier of this product. Bernzomatic sells the same thing (zinc with about 10% aluminium) and it can be found next to their propane torches. Maybe others sell it as well.

Quite right Tim,
I've seen similar products advertised, the main thing is to make sure the damaged area is cleaned properly and that the rod melts in contact with the case and not just drip it on to the case.

Harbor freight sells it as well. I 've used it to repair holes in CL alternator covers. Like was said, slight difference in color, but beats a hole or bad crack, especially since the part is hard to come by. Also repaired some valve cap hex heads as well, which were a little tricky.

I’ve tried using Alumiweld, but never seem able to get the part to be repaired hot enough, even using mapp gas.

Mapp Gas should provide enough heat, I repaired the right hand case that was missing a lug. When I clamped it I made sure I insulated the case from the vice so the heat didn't soak away. Obviously the thinner parts are easier to get up to temperature but it's important to get to good clean metal, oxidised aluminium has a higher melting point and increases the risk of melting the item being repaired.
