The guy @ NTN told me that the CV's they were giving everyone are off the
front of a suzuki 4x4 400cc model, I duno the name. We built a special
fixture to yank them apart in our arbor press (non-hydraulic), it works
pretty well, I'll take a digital picture if anyone wants to see it.
There's a spring clip on the shaft where it inserts into the outboard
cup. It's almost identical to the clip on the stub shaft that inserts
into the transmission, only tighter. Also, the spines on the
interconnecting shaft have a 30' helix on them making them even tougher to
seperate.
Our heat treater tested the NTN shafts. Case hardness of HRC ~60 and core
of HRC ~50. It's some sort of proprietary steel that NTN has a tarrif
exemption for because it's patented by some Japanese company. I did a
little poking around on the web and found out it's basically a 1040 steel
with some sort of boron treatment to increase fatigue strength.
