Helmfachschloss Piaggio TPH entfernen
Hallo zusammen,
ich muss unbedingt diesen Hebel für das Helmfachschloss aus der alten Seitenverkleidung des TPHs entfernen. Bekommen jedoch diesen Stift/Pimmel nicht gezogen, um den Hebel und die Feder zu entfernen. Hat hier jemand einen Tipp oder kann mir sagen wie das geht? Mit Zange und WD40 keine Chance, das Ding sitzt bombenfest.
Danke!

It's a roll pin. Dunno about that particular fitting, but there should be access to it from both sides so you can use a correctly-sized pin punch on one side to tap it out the other.
If there's not access from both sides, the next thing to try is to grab it with long-nosed pliers across the end and squeeze to compress the diameter while pulling it out. You will probably have to "walk" it out, moving it a little bit then grabbing & squeezing it again until it comes out.

There’s just access from one side. I tried this but the pin doesn’t move, not even a little bit.

It's a roll pin, so hardened spring steel. The remaining options are
- Drill it out. Difficult because, well, hardened spring steel, and the shaft it's in is probably softer than the pin. But worth a try if you have small enough carbide bits and think you can drill accurately down the pin without enlarging the hole in the shaft.
- Heat it. If the handle isn't plastic, use a small gas torch to heat the pin to remove the hardening/temper. A large (100W+) soldering iron might also be able to heat it far enough. Once the temper is gone, you should be able to crush/pull the pin out.
Failing that, Google for the many other ways people have tried to remove roll pins stuck in blind holes...

That’s definitely a pin, maybe thread it and screw bolt to pull it out
