H1 headlamp disassembly - replacing chrome ring

[Nordschleife]

How do I remove the adjuster screw/cable (the one that goes to the smaller reflector itself)? I'm at a halt in my work to replace the chrome trim ring.

I removed the other long screws that hold the trim ring. It's just this last screw that I need to remove before I separate the old trim ring from the headlight housing.

The screw giving me trouble is not like traditional screws, it's more like a metal wrapped cable with Philips-head screws on each end (one end adjusts the reflector internally, and the other end appears externally on the chrome trim ring.

Hope this makes sense! Hopefully someone else here has replaced their H1 headlamp trim rings and knows how to remove this adjuster screw.

This is the cable/screw I need to remove before replacing the trim ring.

The factory evidently used some kind of adhesive for that connection. Sometimes heat helps, but the best way to get it done is to cut the screw where it is attached to the cable, leaving 1/4" to 1/2" of thread. You can then remove the screw from the trim ring. When you reattach you can join the new adjustment screw go the stub on the end of the connector using a M4 coupling nut.



Use a little Blue Loctite. Neat and easy to remove in the future.

Let me know if you have a hard time finding them and I'll send you a couple.

Andy, if you hadn’t figured it out yet, that adjuster screw is held into the slot of the small reflector by spring loaded pressure. As for removing it from the trim ring, that screw is attached to the spring cable by way of crimping in that ferrule. Most of the time when trying to get the screw out of that ferrule, the screw itself gets trashed and people end up replacing it and trying to recrimp the ferrule.

Thank you, gentlemen. Much appreciated. John, your idea to cut the threaded rod, and then use a 4mm coupler sounds good. Michael, I think I’ll try the 4mm coupling nut idea, as I lack the ability to re-crimp the ferrule.

What surprises me is that Bosch engineering team seems to have thought that no one would ever want to replace the chrome trim ring!
