Broken Truck Spring
Options
<1> Go order new leaf & wait
<2> Find a truck wrecker with spring leaf of same dimension
<3> Weld the leaf up n get back to work
To weld easy dun
'V' out each side of the broken spring leaf
apply a bit of warm to break (just too hot to tuch)
clamp the broken spring to the leaf next to broken leaf
heavy tak weld
flip sping over & clamp to the other nextleaf
heavy tak weld
check th@ all looks good
weld up each side of spring n grind off to ded smooth
do same other side
fill n grind the edge of spring so Mr Officer can not see weld repair
Assemble n paint then go back to work

In 1973 we broke the main leaf with eye in it to keep the axle in track
we could not buy a leaf or complete spring from KW
We met Mr Magna & he recommending to weld with Magna alloy rods
it still holds today
since then we have welded many spring leaves on our beast but just using Mig welder with common garden variety mig wire with a bit of warm
The KW Manual sez so

I got defected some years ago with a broken second main leaf on the front of my KW, I welded it with Low Hydrogen 7016 electrodes, it passed inspection and still going strong, used a similar procedure to that described by Swish

Hello Hayseed,
I see Magna have an agent here in the West, so guess they are still active over your way.
Their 303 rod on anything above mild steel did all that was required, similarly 770 machinable cast iron rod was the ants pants. (Maybe Mammoth can give a testimonial! He had a cylinder block being repaired with it)
We had a salesman calling selling it, very dear so only used on difficult jobs.
My only qualification is experience fabricating and fixing on the farm.
David.

Back in my short story about the McDonald engine I mentioned I got a weelder to build up the cam gear for me. It was cast steel and he used the correct rod and preheated it and slow cooled it. I was able to us my small linisher to shape the cam and put it together again. However when I got to the rocker arm I had a couple and the first one I chose broke when I was puting it together so I gott he second one out and used it. Then I thought lets see what happens when you weld this stuff up with MIG. I did put a small amount of heatinto it using the LPG burner but no colour achieved, welded the bits together and let it cool over night. Tough as nails is the repair. Again this was cast steel not cast iron.
