Jeff686 Posted April 26, 2010 Share Posted April 26, 2010 My Gold Team stopped working today (just after I finally got the trigger and sear setup correctly). I was worried that I had done something wrong, but found chunks of metal in the dust cover and then saw the guide rod bushing. I've attached a picture. Is this normal? I'm using Henning's new guide rod. I didn't know the bushing was under so much stress? I'm still surprised it broke. Is this common? Happen to any other Tanfoglios?

BritinUSA Posted April 26, 2010 Share Posted April 26, 2010 The only thing I can think of is that the bushing was hitting the frame. What spring weight are you using? Link to comment Share on other sites More sharing options...
Jeff686 Posted April 26, 2010 Author Share Posted April 26, 2010 I'm running a 12# spring. What I can't figure out is what was hitting it. The bushing is not impact bearing (during slide motion). It only holds the spring and lets the guide rod slide through... Link to comment Share on other sites More sharing options...
lord torquestick Posted April 26, 2010 Share Posted April 26, 2010 It almost looks as if your new guide rod is shorter than the old one and caught the edge of the bushing. Link to comment Share on other sites More sharing options...
shooterbenedetto Posted April 26, 2010 Share Posted April 26, 2010 It almost looks as if your new guide rod is shorter than the old one and caught the edge of the bushing. BINGO! this sounds about right. did this happen on the first shot? V12 is short giuderod. V8 is long guide rod. Link to comment Share on other sites More sharing options...
Jeff686 Posted April 26, 2010 Author Share Posted April 26, 2010 (edited) I checked the guide rod. It is the same length as the 'stock' rod, and there is no way it was hitting the bushing. I'm not exactly sure when the bushing actually broke, but the gun started to malf because of the metal scrap after 10 rounds. The only thing I can imagine is that I installed the rod and spring incorrectly. I might have carelessly caught the spring on the lip of the bushing, instead of going inside the bushing. It would then be possible for the spring to reach full compression before the slide reached full travel. As a result, there could be considerable amount of force passed through the compressed spring and directly onto the lip of the bushing. Kinda far fetched, but (as mythbusters would say) plausible.

I would say you are right,...I put the spring and rod inside the bushing and then insert it,...that way there is no guessing. Link to comment Share on other sites More sharing options...
R.Elliott Posted April 27, 2010 Share Posted April 27, 2010 I'm running a 12# spring. What I can't figure out is what was hitting it. The bushing is not impact bearing (during slide motion). It only holds the spring and lets the guide rod slide through... I had the exact same thing happen. Couldn't figure out what was hitting because nothing was. By process of elimination, I'd say spring expansion as it compresses loads the bushing. The bushing (like most of the Tanfo parts) is hardened and brittle and eventually just failed. Mine broke into several small bits and locked things up very nicely. Link to comment Share on other sites More sharing options...

Leo 10 lb Wolf spring if memory serves. The lightest spring Tanfoglio shipped their guns with was the only one that wouldn't nose dive the gun, and I ordered Wolf springs as replacements. But I don't think the spring weight really matters. It would be more about spring length and compression I would think. On the other hand, there may be nothing that can be done about this other than replace the part when it breaks, or perhaps have them annealed before installing.

I guess I am lucky, I have yet to break one. I also run 10lb wolfs but lately I have been running Hennings 10.75. Its a easy enough of part to make with a lathe at least.

askomiko Posted April 29, 2010 Share Posted April 29, 2010 I've never seen that part break before and half of our club shoots Tanfoglio. Good info, gotta get a spare. Link to comment Share on other sites More sharing options...
Jeff686 Posted April 30, 2010 Author Share Posted April 30, 2010 Actually, this was all a ruse to increase Henning's sales. I wanted everyone to think they should stock up on spare parts !! Just kidding. Got my replacement from Henning today. Hopefully, I'll find a match this weekend... Link to comment Share on other sites More sharing options...
