CA, the early DC's as well as the CC's had a Twin Disc type clutch with the same lock pin style as the later over center PTO clutches.It had three fingers, no links, just a cone that when pulled back rode the fingers up itself and pushed a pressure plate The 39 we have originally had a pull back to engage clutch. the adjusting pin on those style clutches was between the fingers and was pulled out to release the hub to turn it to adjust it.

I'd back it way off until it was loose and then bring it back up to find where it snaps over center. mEl
