So we all have those days where you have the magic touch and fook some stuff up, today was my turn. Trying to re-install a c clip on a Timney trigger in CZ 457 MTR and looks like I've dorked it up and will need to replace it (ordered a bunch of Amazon) followed the instructions and still managed to muck this thing up to the point I don't think the original clip is usable now.

I've done these before and had no issue and was able to use a standard slotted screw driver to press the clip back into place and it just seated. Is there a tool or trick to get these little buggers on easily that anyone has encountered. From some reading on other forums a 3/32" sized clip will fit and so planning to try that once Amazon order shows up. A pick set was recommended in another forum to pull the clip apart and slide it over the pin.

Was going to use my channel lock pliers specifically made for these clips but they are too large for this size, so a couple of right angle picks may be the way to go.

Tiny needle nose pliers or a small standard screwdriver works for me. Usually I can get it done with needle nose pliers by just barely gripping the closed side.
 
From RFC Marlin Rimfire-semi forum, 'Arrowdodger' described (and shows in YT vid) using a 'pickle-fork' made of a small, cheap screwdriver with a notch filed in the straight-blade. This fits into the 2-'voids' of the installed E-clip, and with your Thumb or finger holding the clip so it doesn't fly away, just press it off. This takes very little force or dexterity. And the handle end of the 'fork' has an angle filed into a wedge to push them back on, using the same digit to avoid flight. This works wonders on the many E-clips and springs, etc on a Marlin-60, and Any other uses. Been a handy tool for me for many years.
 
The Arrowdodger 'wedge thing' is on a plastic screwdriver handle, so avoids marring the finish of whatever the assembly is. Yes, Looks like the OP has been 'using a bigger hammer' 😉

Are you pressing down on them? No need to stretch them or press on them!

Just lay it flat on the trigger housing and use a flat screwdriver to slide it on. Easy peasy.

Well yes I had been using the tip of a flat head screw driver to press down on them from the top to try and force it over the groove it clip into in the pin, saw a few people do it this on various Youtube videos and it appeared to work just fine.
 
Found this little gadget last night that appears to be dedicated to dealing with these clips and if the screw driver trick mentioned doesn't work out for me I'll give one of these a go.

I'm sure it's made from the finest pot metal and melted down spare parts that money can buy. Appreciate the replies and advice so far with this.
 
Another one that works very well in those micro mini open end wrench kits they sell Amazon or princess auto.

You can use a Grinder or file to thin out the sides and make one for that specific job.

Hope this helps

I guess you could also use a Grinder and cut a chanel in a small sick so it slips over the pin and pops the clip out.

Currently make a similar too for a safe door I'm working on lol
 
Maybe y'all need a picture ? Works on all sorts of 'tiny things', including E-clips but I never tried pickles.
