That's all that is left of the axle! No inner left so I imagine it was pulled when it broke. The stubshaft rattled around in there for so long it has knurled over the lip and I'm having an 'ell of a time pressing out the outer race on the taper bearing.
Time for a bigger hammer... and a beer.

So where do I find a complete long axle?

And the kingpin bearings are done. So bad that the caps have shattered and I cannot get numbers from these. Any input?
Timken number for the roller race on the inner is 462 if anyone is keeping records. Outer race for the outer wheel bearing is 3948.

Though I've had new rear axle shafts made, I've often wondered what I would do if I ever broke inner shaft on the front end. With a bit of luck you could always just remove both inner shafts, as was often done after the war to neuter a four wheel drive truck, this was even covered in some of the end of the war manuals (on US Trucks).

As a starting point for your parts search amount the CMP family how about posting a copy of the exploded parts view showing which bits are reusable and what have been destroyed.

Good luck.

I want to keep it 4WD so I would like an axle.
As I haven't pulled the third member yet I don't know how extensive the damage is. For now I'd be happy with a complete axle as from what I can see this is the only thing I will have difficulty with. Bearings are junk but complete so I have dimensions if the worst comes to the worst...

Although I've had no luck so far here are the IBI cross reference numbers for the radial/thrust kingpin bearings:

ATB: AT13
Carman and Ford: CO1Q3123B
GMC and Massey Furgeson: 900928
Nice (pronounced Niece): 6081 or N1153
Rockwell: 1828K37
MRC: 14FAK379

used the IBI guide for many years, but you need to be a bit carefull, as they group all same sized bearing together.

Need to get advice from a good bearing man, as you could end up with light capacity units.

Regards

Here are some of the cross ref numbers from the Cdn NSN microfiche.

Chatanooga Boiler & tank co, New departure, condec 928

I posted these a while back when I sold my last set of 4 NOS bearings:

The NSN 3110-00-158-6691 is for these bearings. There is actually 1 listed as part of a lot of parts being sold out of Montreal Supply Depot.

Not sure what you are on about ..but a club member here, Len Schutt ... on his C8AX. He successfully modified a C15A front inner shaft > It was shortened and re-splined by a gear cutter ... to fit the C8A diff. It works great ..no problems .

Kingpin bearings New Departure 928 and are now superceded and out of production. An alternative is Aetna A-1570. Expect to pay big $$ for any you can source.
Cup for inner bearing is Timken 453-X, cone is 462
Cup for outer is Timken 394-A, cone should be 399-A
