How do you get retaining ring to fit in the groove of auger shaft for Clam Plate 2nd Gen?

[MidCoast]

I have been trying to get the retaining ring to fit in the groove of auger shaft for my 2nd Gen Clam Plate and can't get it to fit.  Any ideas?

Also any thoughts on the 1st Generation Clam Plate with chuck removal required vs 2nd Gen Clam Plate?

With the 2nd Gen Clam Plate, it worries me that my drill bit  can fall into the lake if the bit falls off from my hand drill or loosens from it.  Thoughts?

It should fit fine, sometimes it needs a little extra umff. Is the ring too thick for the groove? This is the first I've heard of that situation... but it should fit with some pressure... I've had to use a hard tool to really push some of them on but it should fit... shoot me an email if you're still having issues... mjohnson at iceteam.com...
