Hard RTS Clutch
Turbo Mini Forums

Any who has done the RTS clutch I have installed mine it was a 1275 and a 998 springs. I would like to know how hard on the pedal it should be. As mine is very hard I know it is disengaging as the car can be moved in gear, with the clutch down. Any help would be great.
Thanks steve

mine was VERY hard when it first went in, to the point i though something might break but it softened up after a few days,

great thats exactly what mine feels like, to the point that i thought i might not be able to drive it but it does work i just need to man up abit.

get taking some cod liver oil tablets,

out of interest what springs and style verto have you used?

one out of a 1275 and a 998 i think they are the ap type. i also have some play in the pedal it travels around an inch befored it is pushing the springs and when you let the pedal go it doesnt come back to the top of its travel. what could this be any ideas ?

sound a similar setup to mine, AP with two 1275 spring (same as a 1275 probably)

the play could be down to the spacers n the spring retaining bolts being a little long.

would you recommend sorting this or will it be ok running like this if everything works ok?

Mine felt alot softer than a grey diaphragm?

Have you changed your slave cylinder to a Verto type?

everything is verto on my engine i was thinking i should rebuild the slave and master cylinder. is there any way of making the clutch pedal lighter by means of modifying any of the hydraulics as i am going to use this as my daily.

if you have room you can put a remote servo in line.

mine feels like it has much of the operation in the top half of the pedal stroke so i've been thinking about enlarging the bore of the slave cylinder,

or you could maybe alter the slave cyl bracket and use a cable verto arm from a metro, they are a little longer.

ill give it a go see how it beds in then first. mine seems to be at the bottom of the stroke where it does all the operating maybe it could be the hyraulic side that needs a revamp as the shoulder bolts had about 5mm of spacer in them so im hoping its not that which is casuing the play in the pedal it feels too soft to that i think.

When Robert let me try the original RTS clutch it didn't feel too different to a normal verto clutch.

mine is way harder than usual or what i remember it to be i have got used to a modern car so its maybe partially my leg has gone wimpy aswell then.

Mine feels pretty much the same as my old grey.

Ive got a cable type arm if you fancy trying it out.

In the 13's at last!.. Just

im gunna give it a go as it is see how it goes if its no good i might give you a shout and have a go at the cable.

how the springs are preloaded and where they pivot has a massive effect on pedal feel. certainly it did on my RTS, i used to mock up on a press with a gauge and loads of washers till i got the plate to come free with the minimum fuss. doesnt take much :)

thats a good idea. might have to do that if mine doesnt bed in at all.

you kinda want to have it preloaded such that the spring is pretty much flat, so it takes the minimum amount of effort to push it "over centre" .. if you have it sticking out to much then 90% of the pedal effort goes into jsut compressing the spring rather than releasing the plate.

EDIT atleast that was my understanding lol i built 3 RTS clutches, and despite my best efforts, every one had a different pedal feel.

thats great thanks for all the help going to give mine a try on the roas havent got running yet so well soon see.

Evo makes a good point, I did the same with mine. They nearly sits flat when bolted down. The pedal pressure gets progressively harder, then after an inch or so of travel it kind of 'pops' and becomes springy.

I cant remember if mines flat, its just a std dimensions so i guess not.

Having read this thread (and already being concerned about ow stiff it was on the bench, fnargh fnargh). I tweked it last night.

You can't make them flat as this would defeat the idea, as the clapming force will not be maximum. But somewher closer to flat will make for a better pedal.

I made mine liik much like the standard verto I removed, somewhere between 10 and 20deg at a guess.

Now in the engine it feels easier to release than a grey with a big bar on the arm.

time will tell.

what are you tweeking?

I supose its much the same as the diaphragm clutch where you have to machine the horns down on the back plate to get the spring flat. but with the verto, you would machine the mounting lugs on the flywheel instead

from the posts i got the impression that people might be changing the bolt length or somthing,

which would be wrong.
