Flashman Posted September 4, 2012 Share Posted September 4, 2012 I have a new SP 101 which I just discovered has a problem that the the crane assy moves forward when pressure is applied to the back of the cylinder forward. It moves away from the frame about 1/4 to 3/8's of an inch. It can be popped back by pushing the crane pivot back into the frame. Very odd. I discovered this when I first used a new Safariland speedloader. Obviously the cylinder won't closed unless the crane pivot is popped back into the frame. I plan to call Ruger about this but has anyone heard of this before. Other than my query in another forum (no answers), a Google search found only one identical match with no answers. I haven't disassembled this thing but could it have not been assembled properly? It shoots and handles fine otherwise. Link to comment Share on other sites More sharing options...
rln Posted September 5, 2012 Share Posted September 5, 2012 I checked an older sp101 for the play that you described. That one had a small amount of forward movement.....less than 1/8 of an inch, but it would spring back when pressure was released. I want to say that the crane pivot has a spring loaded plunger on the end. Could that be missing or the spring broken? Link to comment Share on other sites More sharing options...
Toolguy Posted September 5, 2012 Share Posted September 5, 2012 I don't do Rugers but if I recall correctly there is a part of the trigger guard assembly that holds the crane in. The plunger in the end of the crane is to operate the cylinder stop, I think. Link to comment Share on other sites More sharing options...
Quack Posted September 5, 2012 Share Posted September 5, 2012 (edited) if you look at the front (top) of the trigger guard assembly, there is a small plunger. that should be what's holding the crane onto the frame. http://www.teslamap.com/public/sp101_trigger_job/index.html Edited September 5, 2012 by Quack Link to comment Share on other sites More sharing options...
Flashman Posted September 6, 2012 Author Share Posted September 6, 2012 Thanks for the replies. The photos are excellent. I called Ruger yesterday and they asked that I not disassemble the gun and emailed a shipping label. They stand behind their products but I am perplexed about the problem. Your responses help me understand it better however. Again, thanks. Link to comment Share on other sites More sharing options...
Flashman Posted September 6, 2012 Author Share Posted September 6, 2012 After closing examing the photos and diagram in the link, I suspect as suggested there is something wrong with the cylinder latch and/or spring. Link to comment Share on other sites More sharing options...
