Clutch stop query

[john-e89]

Bonjourno,

Reading the other thread on mods the guy mentions the clutch stop mod. Being only 5'6" the only gripe I have with the M is how long the clutch travel is, i can 'almost' get the ideal seating position but even though I'm a short arse I like being set back from the steering wheel but the clutch travel prevents the perfect seating position, so setting the seat another inch back would be brilliant. If I do this mod does it mean I can set the clutch stop higher up than the standard plastic one which I've screwed out a little already? I haven't moved it much as it's a crappy flimsy affair and I don't think it would take much to break it. Reading on the American forums on the other post it seems that clutch engagement happens quite a way before the clutch stop so I'm hoping I can gain an inch on the pedal.

If anyone knows please shout up, if this is possible without interfering with full clutch engagement it'll make my day, I'm absolutely loving the M, this would make it even better!

Cheers in advance lovelies...

Personally I wouldn't bother.
I suppose you could adjust it to the max but then risk the longivety of the synchro rings in the gearbox & the clutch itself.

Disengagement will be at the same point no matter how far you screw out a stop.

All you’re doing is stopping the full disengagement by decreasing the pedal travel. If you want to do that, then just don’t push the pedal down as far.

I think clutch stops are for lazy people or those with no mechanical sympathy, who just want to mash the pedal to its limit and not worry any further.

I'm very mechanically sympathetic Tony, I guess 33 yrs of driving I'm set in my ways of dipping the clutch to the floor. I just want to set my seat back a touch to get the ultimate seating position, I don't mash the pedal, but if there's a stop I sometimes reach it, I'd rather have a stop than not, then I know I've completely disengaged the gearbox.

John, I tried a clutch stop on my ///M and found it prevented the clutch from fully disengaging. My clutch disengages fairly close to the floor, so if yours disengages higher in the pedal travel, it might work with your Zed. If I can find it, I'll send it to you if you'd like it.

I would agree with Argenta. Personally I wouldn't risk to put it very high. But a trial and error will convince you, since it is not an expensive mod and you can throw it away if it doesn't suit you.

That's strange? A clutch stop was maybe the first thing i bought for my M years ago. Even with it installed the clutch bite point is well before the stop. I keep it at its lowest point which is i would guess around 3cm further out.

Because I'm a short-arse, I bought this one a couple of years ago and it's been great

The cutch bite point will vary between cars and might change as the clutch wears (though mine has taken up close to the floor for all of the 8 years and 50,000 miles I've had mine).

I'd be quite happy if my clutch disengaged / engaged in the first third of pedal travel. Then, with a tall clutch stop, gear changes would be possible with only a few centimetres of pedal travel.

A very kind offer my friend, thanks very much.

As yours my clutch disengages close to the floor, having done some specific testing I've come to the conclusion that a clutch stop wouldn't make any discernible difference, so I'll leave as is.

It's not a problem as it is, I'm just on a mission to create the ultimate M for me and any improvement is worth exploring but this won't make enough difference to bother.

Just on a side note, I went to the Brompton, I saw Alana Heart, a colleague of Michael Polkey, if you've heard of them.

Thanks again, hope you're enjoying the sunshine on what I'm sure is limited time off.

Cheers for the link Perry, hardly worth breaking out the welder and making one for that price is it.... :lol:

I don't know either of them but google suggests they're both well respected (assuming it's Alana Hare not Hart?). I hope she gave you encouraging news?

It's the lack of sunshine that's a bit limiting at the moment, rather than a lack of free time...

 

[Beedub]

i absolutely hate this mod....

 

[Z4M-2006]

You got the CDV removed John ?

May make your clutch action feel better,it did with mine lthough some report little or no difference. It wont make the clutch bite at a different point but made the clutch pedal feel "more natural"...

Maybe worth a try as its free ?

Not yet Gaz, it’s imminent, as soon as I’m back on my feet it’s getting done.

Oops yes Alana Hare, typo.. :roll:

Well at least she knew timescales etc which i couldn’t get up here in Sheffield. Another year from now before any nerve recovery will start, another year after then for it to recover if it’s going to, which is pretty much 50/50. So all I can do is wait another two years and hope. Glass is half full, not empty, and I’ve put my money on red on the roulette table...let’s hope it lands in it...!! :lol:

 

[BMWZ4MC]

That's a timescale that would try the patients of most people, although the odds aren't too bad I suppose. I hope it lands on red, and sooner than two years, but did she talk about a Plan B?

Thanks although Alana is pretty confident it won’t be before two years as its a high level of paralysis, my lung function on the left is very low hence the 24/7 oxygen, the right lung is still completely static, no movement as of yet and it’s been almost a year since the ablation, but maybe this one will prove her wrong, all I can hope is it gets its backside in gear and grows back. I see her again in December for a 6 month check. What worries me is as far as I understand if the area of paralysed nerve is too great the new shoots of nerves either side of the dead area cannot cross a too large gap, much like if you don’t let runner bean shoots wind up a pole they just fall over, and as this is a high paralysis level it’s on my mind, but I’ll talk to her about it next visit. No plan B, there’s no treatment if it doesn’t recover, all they can do is plicate the diaphragm, pull it down and pin it, which is not reversible. I’ll be on oxygen for life, I can’t think about it too much, I’ll deal with it if it happens.

Thanks for your interest, it’s much appreciated.
