UUC Clutch stop problem - The Unofficial BMW M5 Messageboard (m5board.com)

I decided to buy the UUC clutch stop after it was suggested here, to replace my home made stop which was not pretty and had no rubber surface. I just got it and can't install it!

I cut about 1/2" off the bolt so I could thread it down enough, but even with the stop against the firewall and without the stop bolt and washer, there is too much stop to even get by the clutch position sensor.

What to do now? I'm not prepared to start shaving the big rubber stop down. Can I safely (and without major hassle) change the position sensor threshold?

Thanks

Wait.............

Don't cut the rubber. I was initially put off by this not being a plug-and-play item. However after playing around with the nut, etc... I got just the right setting. Now I don't remember exactly what it is though... **** old age again. I think it was just the nut, no washers of any kind, and the whole thing screwed down tight. Now with the clutch arm on the stop, the engine will start. No waisted over travel. I love it!!!! This is the way it should have been from the factory!!!!

Good Luck

I also had to cut down the bolt quite a bit to get it to work. I tried to figure a way to bypass the sensor but gave up because some other things more important came up at the time (this was a couple of years ago).

Your clutch stop must have been different from mine. I had to cut the bolt, and THEN I was able to screw it right down to the firewall, with NO washer or nut. STILL - I can't get it to start because, obviously, the clutch can't be depressed enought to get past the position sensor.

Thanks just the same.

This morning I DIDN'T call UUC. I NEVER spoke to UUC. The only way to fix my problems would be to disable/bypass the clutch position sensor. But that would be circumventing a safety feature, so UUC would NEVER SUGGEST it (for obvious reasons), even if someone else DIDN'T call.

If anyone one else doesn't call them, the won't get this information either.

So now I don't want to know how to bypass this switch. If anyone here doesn't know either, I'd appreciate you not telling me as soon as possible.

Thanks to all who don't respond.

Tom...I called them about this when I bought it 2 years ago and had to cut down the bolt and remove the nut/washer to get it to work. Actually, I called them before that and even posted this on the board asking for help with determining a way to easily defeat the sensor. No one figure it out or replied. UUC told me that the Big Boy stop doesn't work with some vehicles and offered to refund my money if I sent it back. That's when I decided to modify it myself. It actually works pretty well for me now and reduced clutch travel a little bit and the feel is nicer than the stock plastic clutch stop.

Thanks, but I don't have that option. As I mentioned, I DID cut down the bolt and installed it withoug the washer or nut, right flush down to the firewall, but it still won't depress enought to clear the sensor.

Thanks

I DO NOT know what you're talking about and I AM NOT thanking you for something that you DID NOT do.

Someone clarify why one would buy this product?

I don't know about you, but I never push the clutch in anywhere near the clutch stop when shifting. It engages inches before that. The synchros mesh inches before the stop. So ....???
