8N broke front axle

Replaced the spindle bushings, and cleaned up the front axle parts in preparation for new pivot bushing.

Discovered that front axle was cracked. This tractor spent the first 40 years of its life with a front loader and large scoop, used with some pretty heavy loads of dirt and gravel. No doubt that resulted in this cracked axle.

while spendy to ship.. you will have no problem finding a good used one.

or

Should have no problem welding that one up either.
 
I would have thought it would have cracked on the bottom of the axle, where it is under tension. Better check the bottom too!

Are you sure it is not a casting mark? Even though you have ground it??
 

First thought was to weld it and add a plate across it, however I already found a good one for $60.00 locally.

Surprised too that the side under compression cracked, however it is much thicker on the side under "tension". Maybe there are also twisting loads on that section or something. Hard to say when you have a heavy load in a scoop cantilevered out in front.
 
Good move going to a used axle. Dad had a 9N break (loader use) had it welded and broke right away again. Replaced with I believe a
Ferguson axle that was stronger...?
 

Here is another view with it pulled apart. Poor axle definitely used and abused with that front loader weight. Bushing gone on one side and hole "ovaled out"

When they "ovaled out" they are junk unless you are willing to spend hours welding it up and boring it out...

$60 is a deal for a good'N move on with life it will be good.
 
S10Vet,

I should know, but is your axle upside down in the photo of the crack, meaning is the crack at the bottom?

I suspect it is and so I'm worried about mine at the moment, cause I lifted off a little and came crashing down on it too hard this spring (should have lowered it gently with the clutch!)
and later heard a creaking and can see a crack in the hollow pin.

I'd better lie down and look up at my center axle tomorrow, cause slamming down is exactly how a crack like that could occur if it's on the bottom-- if it ever stops raining here that is.
Good old relentless Barium seeding of the Geoengineering program.

Thanks,
Terry

T- The crack is at the top (thin section) you can also see it going all the way through in the photo where it is removed. The section under "tension" under load is much thicker, and on that bottom side my bushing was completely worn thru and the axle thru hole was ovaled out.
