I've been playing around with pulling some junk cranks apart and the hole of the FW side where the pin presses in seems to have some sort of super high temp high strength braze. Or am I imagining things?
Pulled a few junk 066 and 046 cranks apart and noticed that it seems to be the main thing that keeps it snug, and it's tough stuff! Really well adhered
Heating that whole area enough to braze the pin in would really mess with the hardening of the pin.
All the three piece saw cranks I've disassembled are just an interference/press fit.
People do weld them to insure they don't clock out but that's usually a few small tacks with tig/mig.
Is "fretting" a possibility? I bumbled across the helicopter link, some time back, it has a number of interesting reads.
The rest are just a quick pluck from google.
Interesting read but after monkeying with it some more after orginally not touching it until I figured out what it was. I wiped it off with my finger, just half burnt oil
So in conclusion it's press fit, which makes my life much more simple.
