husky 550 oil tank crack

[carlos]

we have a husky 550 with a cracked oil tank , the crack is on the front of the saw ,it has a few cracks as if it has had an impact.

we where thinking to clean it and grind the paint off and put some sort of chemical metal , glue stuff to repair?

anyone tried this and what product worked?

if that doesnt work then i guess its a new crankcase and rebuild.

thanks carl

I've a Dolmar 112 that my dad repaired a cracked crankcase on in about 1985, still going. Just make sure the repair is really clean before you apply it, which will be tricky on the oil tank. I'd overlap the patch on the outside, blend it in then can of spray.

As above, empty the tank, flush it, clean the area thoroughly with brake cleaner as it is a superb de-greaser.

I would recommend two products: -

1) JB weld, an American two part epoxy with fine ground metal in the resin. Dries very hard and sticks well.

2) One I have managed to fix fuel tanks with....Milliput epoxy. This stuff is damn weird - it comes in two sticks, cut off equal lengths and roll together with your thumb and finger. The weird bit is you can smooth/shape it with water and once dry, it resists pretty much anything. We repaired a casserole dish with the stuff and the repair hardened like porcelain and went through the dishwasher a multitude of times with out it falling off - it repaired a thin handle so didn't have a large area to grip to so was impressed. I rolled a ball of it and it ended up like a marble in hardness.

 

The oil tank isn't under any pressure so it should hold pretty well unless it gets a direct hit on the same area. You could bond a thin metal plate to the repair to protect it.
