blueorb Posted October 17, 2013 Share Posted October 17, 2013 Hi all. I have a CZ 75 with CZC's short reset trigger system. I ordered the gun directly from CZC with the work done in their shop (ie...this is not a home gunsmithing job gone bad). Lately, my trigger has been making a lot of squeaky noises on both the trigger pull and return. It actually is developing a gritty feel as well. It certainly did not have a squeak or feel gritty when I received the gun. The gun probably has around 2000 rounds through it. Is this at all normal? Any way to rectify this? Video is below. Might want to turn your volume up. [yt] [/yt] Link to comment Share on other sites More sharing options...
kneelingatlas Posted October 17, 2013 Share Posted October 17, 2013 Very strange, not normal I would switch guns and call Stuart Link to comment Share on other sites More sharing options...
blueorb Posted October 17, 2013 Author Share Posted October 17, 2013 Ok, thanks. I sent an email to Stuart. Hopefully, this is something that I can fix as I don't have a back up gun. Link to comment Share on other sites More sharing options...
eerw Posted October 17, 2013 Share Posted October 17, 2013 (edited) squeaky wheel gets the oil. sorry..got oil/grease on the trigger return spring? oil there, oil the trigger bar spring. * just replied to your email too Edited October 17, 2013 by eerw Link to comment Share on other sites More sharing options...
Andreas Posted October 17, 2013 Share Posted October 17, 2013 I'd blow out the internals with brake cleaner, apply some oil, and try again. Link to comment Share on other sites More sharing options...
motosapiens Posted October 17, 2013 Share Posted October 17, 2013 one of my 75's is somewhat prone to getting rougher as it gets dirty. it seemed to be between the trigger bar and the frame, so I took it apart and polished the outside of the trigger bar lightly (mine is pretty roughly finished), and also cleaned everything up. brake cleaner might work if you are averse to the idea of disassembling the gun. You have to remove the safeties and sear-cage assembly and trigger pin to get to the trigger bar. That's an easy job if you have a cgw trigger pin.

I actually sent you an email as well. Yes, I just cleaned the gun and, when reassembling, I made sure to oil trigger return spring and trigger bar spring. I'd blow out the internals with brake cleaner, apply some oil, and try again. This is my very cleaning routine. I blast with break cleaner, clean and then oil. Will try again...

I have never disassembled my 75 and am really reluctant to do so without someone around to fix any screw ups. Will pay attention to the trigger bar though. Thanks.

eerw Posted October 17, 2013 Share Posted October 17, 2013 truthfully I hate break cleaner, cause it strips oil from every where. make sure oil in hammer, sear, sear spring, hammer spring, hammer strut. let me know if any relief. Link to comment Share on other sites More sharing options...
kneelingatlas Posted October 17, 2013 Share Posted October 17, 2013 I have never disassembled my 75 That's your problem right there I would completely strip the whole pistol, clean everything spotless, then polish everything and put it back together again with some Slide Guide I found some 3000 grit sand paper at the auto parts store which spongy so it gets into all the little spots and works bitchin'! (plus it's impossible to take off too much metal) Link to comment Share on other sites More sharing options...

Well, I think I will stop using the break cleaner. I have field stripped and reoiled everywhere I could. The trigger return squeak is now gone. It's quiet and smooth again. I am still getting the squeak on the trigger pull. The squeaking is coming from the rear of the gun. Something in the hammer, sear-cage, etc area. If it helps any...it only squeaks when I let the trigger go gull forward to reset. If I pull the trigger and pull again before it fully resets it does not squeak at all.

(plus it's impossible to take off too much metal) Lol, I am not exactly mechanically inclined. And it appears that the CZ is one of the more difficult pistols to work on. I would really need a full detailed write up on how to disassemble/reassemble. Anyone know of a very thorough one? With pictures preferrably? LOL..

blueorb Posted October 17, 2013 Author Share Posted October 17, 2013 Would love to but that is a long ways from me. Well, if I try and do this, is there anything in particular that I need to be worried about/pay attention to? Link to comment Share on other sites More sharing options...
eerw Posted October 17, 2013 Share Posted October 17, 2013 Just watch for small parts/springs. most people aren't aware of the detent spring and plates. stuff like that. clean surface, go slow, watch for small children and small parts Link to comment Share on other sites More sharing options...
kneelingatlas Posted October 17, 2013 Share Posted October 17, 2013 There are some very detailed Youtube videos out there for the 75B, I just don't have links handy at the moment. Link to comment Share on other sites More sharing options...
CZinSC Posted October 17, 2013 Share Posted October 17, 2013 Shannon, you're not too far from me. If you ever wanted to take some time to learn, I'd be willing to lend a hand. I've had my SP01 down to a pile of parts a number of times. It's intimidating as hell, but once you do it, it's not that hard. It helps having internet and video nearby for reference. The hardest part is remembering the order things go back in ( ie: hammer pin detent BEFORE left side safety detent and spring...i think i screw that one up every time! ) Anyway, let me know if you are interested. I'm busy the next couple of weeks but after that, I"m pretty free. Link to comment Share on other sites More sharing options...
