Remove Front Element Mamiya 127mm F4.7 Sekor P Press Lens

Hi all,

I have the Mamiya Press 127mm f4.7 and it's developed a bit of oil on the shutter blades. Shutter speeds are still good, but I want to get at it and clean it before it gets worse. I've gotten the front element off but I cant get the next element below it. I've tried rubber grip tools to no avail and I don't see any catch for the spanner wrench. I've also tried screwing the whole front piece off with my hands, but it won't budge. I'm certain I've done this before, but maybe it was with an older model. This is the newer one, all black, and it doesn't "collapse."

Any suggestions would be greatly appreciated.
