Clutch Pedal Stop-Screw

Post by **NafemanNathan** » Thu Aug 13, 2015 10:42 pm

What size is the stop-screw for the clutch pedal? I thought I remembered Rich at PAW telling me it was M10x1.25, but that's too small, so I tried an M12x1.25 (Probably what Rich told me). It screws in and doesn't pull out, but there's loads of degrees of play... Like loads... Almost as if there's a captivated thread insert in there to allow movement.

Is that the case? Anyone know what size it should be?

It's in my 5th gen, but there's a chance it has 4th gen pedals (since it's been converted from an auto and has a 4th gen gear-shifter setup). I don't know if that would make a difference.

I think it's also the hole that the cruise control sensor goes in if you have cruise control... And Lings says it uses a 12mm locknut.

Clutch pedal stop screw?
Wot? Where?

I have the full pedal assemblies out of the 4g breaker at the barn and a set of vernier calipers and thread gauges, so if you can point me at what you're talking about, I can measure it all up for you.

Here's a decent picture...

That bottom right arrow points to the nylon stop pad (which I'm also missing), and the corresponding plunger that you see in this picture which I believe is cruise control related is replaced with a stop bolt and lock nut in non-cruise control models.

So I just need to know what size thread that is, and if there's a captivated insert that allows play (Although I don't see why they're would be).

M12x1.5? Had a look on Lings and they only describe a nut that goes on the end of the adjustment screw as being a 12. I hope that's the correct one I were looking at though

Yeah, that's the same nut I was refering to at the bottom of my first post. Looks like a fine thread though, so M12x1.25. I've tried an M12x1.25 bolt and it screws in very easily, but it's the amount of play that has me baffled.

Fine thread? Possibly m12x1? I'm just guessing now ha ha

British Standard "Fine" thread is M12x1.25. British Standard "Coarse" thread (default standard) is M12x1.5

but does that go for Japan too? As I swear I've read somewhere that they have some "x1" pitch threads. Either that or I've been dreaming about some weird jobby again ha ha.
