M952 dust cap tool?

[jimbog]

Hi all, I’m trying to get the the lock but/dust cap thing off is this crank arm. In true retro part fashion it being an arse. I’ve tried releasing spray and a small Allen key in the hole but with no joy so far. Is there a special tool for this that can be bought for cheap somewhere? Always like to add new tools to the tool box. Can anybody point me in the right direction?

It's the same shimano tool that you use for the back of chainring bolts. (TL-FC21)

Or the smallest (red?) park springy pin spanner works.

Pin spanner is what you need. Buy a good one, or a good set, they have many uses and cheap ones are nasty, especially the ones with removable heads.

Proper version: pin spanner.

Emergency version = one of those really large paper clips. Bend and cut into a U shape. Bend each end of the U to form 3mm pins. Bob’s your lobster....

But ISHAW is spot on. Jolly useful to have a few good pin spanners such as Park.
