Need SP 101 help - stuck crane latch

I've disassembled every piece and part (only the ones that are possible outside the factory) on several SP's and a GP before (it has been a while, though,) and this is the first time this has happened to me.

I was disassembling her to perform a full clean and polish routine, and I removed everything else off the frame, then the crane latch pivot screw (KW02700.)

I didn't hold the crane latch (KW00900,) then the spring (KE57) pushed it out, and now the crane is lodged stuck by the plunger (KH05100.) I can push it to an extent, but cannot free it. I have tried for hours with needles and small pokers to go in through the hole for the crane latch screw, and I've tried to get in the gap in front of the crane latch, but I can't get any purchase on the plunger to allow the crane latch to be swung free.

With the crane latch swung out of position, and the spring and plunger blocking it from moving back to the left a small amount (I suspect this would not happen if the spring was fully compressed, allowing movement of the crane latch,) the right edge of the crane latch is prevented from moving forward by the right side of the frame (directly to the right of the hammer's passageway.)

The crane latch is listed on Numrich Gun Parts Corp as a factory-fitted part.

Has anybody else had a similar problem?
What did you do to fix it?

The first is from the top, looking into the hammer passageway. You can see the thumb-depressable portion outside on the left, and the internal portion stuck rearward.
The second is from beneath with the crane latch pivot screw visible.

Dear RF.net members,
I referred this page to Ruger, asking for help. Please bear with me...

Dear Ruger,
Yes, I have placed three calls, and my issue cannot fit within your 500 character limit for "online requests."
I have asked to be forwarded to an expert on revolvers, but I keep getting referred back to the videos on your website, and can't get ahold of somebody who can tell me about this issue.
Hence my email with a link to this website, attempting to get somebody to focus on the issue, not the your videos, no matter how many times I tell you it's not covered on the website, or asking to get further than somebody who can't push "9" to forward my call.

Cheers
Steve

Steve I know the sp is smaller than the gp & but stikin it in the slot then rollin it up has worked eventually for me .

Clamp the barrel in a vise (padded of course )to an optimum angle, then 1 hand to hold the plunger down while manipulating the latch into place.

Be sure to clean all the flash off so it is flush with the recoil shield while ya got it out !!!

Usually when they are stuck like that, it's because the plunger has found it's way out of the hole in the button, and the flanged head is wedging itself between the button and the frame instead of going back into the bore. Whether a pick or the tip of a fine driver or knife, it just takes a bit of finagling and holding your tongue just right to get it back in, and remove the button.

This is likely one of the reasons it's a factory fit only part. Another being how common it is for owners to bend the pivot pin upon trying to reinstall and cause the button to seize. You can rest easy, however, if you can't get it apart and back together, you always have the option of sending it back to Ruger to let the pro's fix it.

Good news if anyone else makes this Bone Head mistake. After several hours my Wife found me a Needle that was close to the diameter of the Crane Latch Pivot. I worked it in slowly and was able to compress the spring so the little Bugger popped right out. When I went to install it the same thing happened but this time I was able to get it out with one try. Third time was a charm and I got it back together. I think I'll leave the Crane Latch alone in the future.

If you run a screwdriver or tip of needlenosed pliers through the rear of the frame and hold against the back of the flat bar on the latch button, you'll prevent that condition altogether. Of course, to do so, the revolver needs to be in a vise or other fixture to allow free use of both hands. I'm not even above having my wife assist when I reinstall these latches to offer a third hand and help focus on alignment. It's not difficult, but it'll get frustratingly locked up very easily. My wife's turning into a fairly competent garage gunsmith herself after helping me with so many little projects - "hey, hold this," or "put that pin in this hole," eventually she started doing her own projects.
