Right,I was asked to look at this yesterday,first off let me state i've never attempted anything like this before,but i'm pretty confident to give it a go,you dont learn if you dont try
This little job is a repair to a old FORD tractors(1940's if i'm right) bell housing, the customer doesn't like the look of it or trust that its sound,so has ask me if i could sort it(gulp)
From what we've sussed out(by a very old gentleman from the old farming days) the damaged was done by it doing a wheely and coming down with some force on the front wheels hence cracking the bell housing,see the following piccys
Little hole at the top was drilled to stop the crack running further,the housing appears to be 10-12mm thick
theres not much to see from the next one but just to give you an idea
Like i said,the customer doesn't like the look or trust the repair,got to admit it does look pretty rough,how the repair was done before we have no idea,i would have guessed by stick/mma but who knows,he was thinking of migging it using SS.
So,basically chaps i'm asking for advice,but i have an idea in my head how to go about it
The lenth of the crack/s runs about 400mm long of course my first start would be grind the old weld off to see what i'm up against
If i can find the original crack i thought V the whole length of it out,or would it be better to say do 100mm at a time,then weld?
Method
Pre heating, as you can see its a big lump i have OA and propane but to keep this hot all over i'm worried will i be able to keep it hot enough to weld it all or like i said above would it be best to do it in sections,what about warming it down also?
Can i also stress this is being done outside and its to be done fitted meaning theres no way of me getting it all apart.
On the welding side, as this is an out door jobby away from any leccy for over a 100ft i like to attempt this using my weld/gen on AC,using 2.5 Ni99 rods(unless you can advise me better),around 80amps?
Again pretty new to this sort of stuff so any advice questions comments tips or tricks i'll be happy to take on board
Cheers chaps
