Can any body see any problems with me welding this into the wok?
Turbo Mini Forums

no idea what the travel is, but will measure it on the verto setup i'm fitting at the weekend.

I have worked mine out from the info on slave movement on marcel chitacks site,

but assuming .160" travel on a preverto with a arm ratio of 5.6-1 that gives a travel of approx 1/2" with the verto arm of 1.8-1

One thing I would change is not to use the mini clutch release bearing. I have seen many of these fail last season. This would be an ideal time to replace the bearing with something a little more modern.

Finding something more modern is not as easy as it sounds though Jim. Bearings are seemingly HUGE (with all the other crap around them) or damn expensive.

I've actually been working on this concept myself over the past year when i realised I needed an equivalent pivot point for my cluch exactly half-way between a verto and pre-verto...

It really puts a dampner on things when you realise you have to design something else to make the first thing you were designing work LOL
Anyways - it wasn't needed in the end - as I changed the clutch - but sent some drawings out for quote a few weeks ago and realised why everything is now made in China....

I did wonder if you would be interested in this to go with your clutch design, but i thought you might not want to change too many things at once, LOL

its sad that just getting stuff made is a thing of the past, yes you can get it don but it cost a fortune!

well as yu say i'll get it in and try it and fettle it from there.

Agreed. I look at stuff MED is listing and am amazed stuff can be turned out that cheaply. This is why I now have a lathe at least (two right now actually)! I just need a CNC mill to make the workshop complete!

Good idea, but I would have a flange so if it packs up you can replace it easely.

Opel/vuxhaul have an hydrolic clutch trustbearing/cillinder in one jobby mounted in the flywheelhousing, works great till it starts to leak , an then the whole gearbox needs to come to replace a 30 quid part! nice huh them modern wonders

( ah yes sir, your clutch slave cillinder had packed up, your bill comes to 735 pounds, the cillinder costs just 35 pounds and the laber was 10 hours at 65 pounds an hour.) sir says "you're fooking nuts it only takes 20 minutes too change a clutch cillinder"

Now try and explain to him how the car was disigned

Cheers, Andrew

very ggod point carl!

i will look into that and polish up on my trig lol

The angle of the slave shouldn't make a difference - so long as the slave is mounted normal to the side of the arm it is contacting at mid-stroke (if that makes sense)?

Basically if the Vertyo arm was a 90-degree L shape with the slave oriented vertically but with the same leverage ratio it'd work just the same.

Wouldn't it?

i think i disagree here TD, but had 4 tramadol today so bare with me

technically the angle will make a difference imo

as different angles, will provide varying movement tangentially to the arm's pivot point on the wok for a given stroke

but as its crude 'pin in cup' (effectively a jointed arrangement), id think it will have little, if any real bearing in our situation

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

well,

after thinking about it for q bit i think the answer is yes and no,

as joey says the ratio will change due to the arc the verto arm moves through, and as the verto arm is pretty short this will change a fair bit as as the arc is moving about a small radius (well much smaller than the pre verto)

but, if what i suspect is true (and TD is hinting at what i think he is) the vero arm is set up so that at mid stroke it is perpendicular to the clutch slave, meaning the ratio will not move that much from the ratio i calculated from thr lengths of the arms.

yes ,yes ,yes but now much does the verto plunger travel,ffs.lol

jesus!

i said i dont know FFS! lol

i will measure at the weekend.

^^^^ LOL :)

I seriously doubt it!

Ha Ha,

PMSL whats a vernier?

the travel is .002674 furlongs.

My arse it is

WWW.FORCE-RACING.CO.UK PLEASE CLICK HERE

One furlong is 220 yards or 7920 inches, so .002674 furlongs is just over 21 inches which is a hell of a lot of clutch travel, so i stand by my comment.

Primary school maths aside, how is this coming on?

lol,

yes, that was a figure pulled out the air...lol

i havent done any more with this yet, after trying my rts and finding the bite point is right up the top ofthe pedal i have decided i can stand to go for a larger piston,

so the current thought is to up the ppiston size to the same as a metro brake piston, I then have the seals sorted and a stainless piston available for use.

I will get some bits payday (friday)

Did you go any futher with this Joe?

Hehe
