Default Best way to add a new clip for piston pin for new piston head. Help and advice needed

Hi all, I'm just in the middle of restoring an old Kyosho GX15 engine and have recieved a new piston head and shaft as well as the pin and clip but i was wondering what the best way is to add the clip. I don't want to force it in as it will scratch the piston head but it is so small i also don't want it to spring off incase i loose it. Is there any tricks of the trade to add the clips or any type of tool you can get to make the job much easier as i want to get this right first time around without damaging the piston head or loosing the clip altogether. Any help and advice would be greatly appreciated or if there is any videos on how to do it without any issues would be great as well. Many thanks.

Hi! I imagine that on your pin one edge is flat and there is a hole on the other side (like an empty cylindric shape)? If that's the case and you want to replace both clips you can start by inserting the pin and tuck in the clip in using the edge with the flat side as a support, then flip the pin and put the rod too then tuck the second clip the same way.

I would recommand to do this process inside a big transparent plastic bag, just in case the spring clip fall out, you can still find it inside the bag, hope this will help.

Hi all, Many thanks for all your help, I tried again this morning and managd to get it in with no issues at all, What i did was wrap some celotape around the piston head and made a hole with a craft knife so i wouldn't scratch the piston head, Then i got a large clear bag so if it sprung off i wouldn't loose it and then managed to push it in with my thumb nail and needle nosed tweezers. I'm well pleased with the result as i didn't scratch the piston head at all and it went in with a little bit of effort so thanks again i appreciate all the help. Well take care all and many thanks.

Well done! It can be really tricky getting those wrist pin clips in! Next time you do a set I use a cork to help seat the clips into the piston recess. The bag is also a neat idea...
