Mechanism disassembly

[dchalhub]

Hi,

I need to disassemble a mechanism which is part of a circuit but I have no idea what tool to use or how to do it.

The pictures of the assembly can be found in the following links:

Thank you very much

I am not aware of a tool to be used to cleanly remove those...
A small flathead may be able to bend the teeth up to allow the caps to be removed, but the flathead may be damaged in the process, and the caps would need to be bent back into place before reassembly. (Possible that restoring the caps to 100% is not possible.)

Perhaps someone has seen a unique solution to these things?

Fit a tiny flat screwdriver in a radial gap and pry open as suggested above. By the second or third gap it will release.

I am trying to do that with no success.

The gaps are too small, I can't fit a screwdriver properly.

I had a feeling you would have that problem. I have some tiny flatheads, but none I would carelessly use to try to pry those open.
Only other thought is an OLFA blade, but these can be brittle and snap. Not to mention they are very sharp. You can't get those out from the other side?

No...
The other side is like that:

Eww... I hate running into parts like that...
I don't have any other tips or ideas.

Thank you anyway

Plan B.
Hammer under the clip a knife and twist. Or insert a flat screwdriver as soon as there is any gap under.
Plan C.
Grab the outer edges of the clip with plyers and deform it squeezing.

Your avatar is fitting. Brute force!
I think that's all there is to it though

They are a use once only part, you prise them off with a small screwdriver, then use a new fastener if you can find them.
