multi plate clutches

Post by Mc Tool »

Looking for experience with multi plate clutches . I have above knee amputation , I also have a mk3 Capri .......and a 3.9 rover :D
The plan was to fit the rover and toyo 5 speed to my mk2 escort but when I crashed the bike I flagged the project and kept the motor/5 speed. Now I have the capri but not the leg . The plan now was to fit a 4hp22 but Im hung up on the manual thing so I did a bit of mucking about trying to fit a hand operated master cyl off a motorbike to the gear lever but I was unable to get the required travel at the thrust bearing without excessive hand lever effort. I believe a twin or triple plate clutch has a bit less spring pressure and thusly less lever effort..... but just how much I dont know.
Any body out there have any experience or even a helpful hint . I dont feel like coughing up1500 bucks to find out its no better ... or not better enough.
Thanks

In theory with a multi plate clutch you can have a lower clamping force/pedal effort for the same torque - don't know how this is in the real world?
Some TVR's had a twin plate clutch - don't know if this was with the Tremac T5? or if this reduced the clutch pedal effort?

You can also get a clutch 'booster' similar to a brake booster. Would be much cheaper than a twin plate clutch.
example:

Or maybe you could re-work a remote brake booster to work with your clutch hydraulics?

It's all relative. A multiplate clutch could have less effort required, but most still do as they're intended for higher power applications, so end up needing that clamping force anyway.

Easier option would be hydraulic assistance via servo or similar to whatever you have, or some sort of automated actuation...but that's getting expensive.

Or just be realistic and do an auto.

What does insurance think about you trying to drive a manual ?

Or although it'd be more spendy, do a ZF8HP auto, then you can have flappy paddles, full auto, and there is an option of a virtual clutch so to speak. There is a pedal linked to a sensor, so you could have the pedal as light as you wanted.

Thanks for the replies .
I simply dont have room for a booster , looked at that a bit , even an in line booster would be hard to place . I have the 4hp22 with all the bits needed to make it work , apart from the driveshaft yoke , so Im sorta ( financially) stuck with that .
Insurance :lol: Had the crash in 09 but didnt get the chop until 19 ( right leg above knee ). In the meantime I could still drive manual ( with a non union femur ) so that was ok . After the chop , now driving auto ( until insurance renewal time )using left foot insurance insisted that I could not drive a normal car and had to have a left foot accelerator fitted ...., connected by a cable so that when I folded the left one down the right one folded up and vice versa .....but it was ok to drive 400km to Christchurch to get it fitted , and this was after I had been driving just using left foot . When you dont have a right foot getting in the way this is easy . Even with the left foot acc I still used the normal acc pedal as the leftie was problematic in that when there is a pedal under my left foot my brain kept thinking it was a clutch ( like the 1st 40 years ) just ask them German tourists that had to leap for their lives as I powered up over the footpath whilst parking in Queenstown .
Anyhow I had to do a panic stop one day and I caught the folded up leftie with the side of my shoe and instead of easily stopping I powered up the arse of an old lady righting off both cars ( one of her rear coil springs came thru my windscreen ) fortunately a), there was no real injuries , just airbag and seatbelt bruising , and b) , the cops saw the situation for what it was and I only got a letter warning me to be more careful. After a brief and very forceful discussion with the insurance co we decided to not bother with the leftie in the new car :D

Crickey - quite a journey!

The remote boosters from older cars can be positioned 'relatively' anywhere - they are usually 6" or 7" diameters. Maybe could fit one under the dash? Hydraulic line from your clutch master in - then line out into your clutch slave. Would need to ensure there is enough fluid volume.

Being realistic, sensible and safe. A full auto is the only real option here.

A Mini or Alfa GT booster in the boot or in a wheel well will fit that bill nicely, but you may struggle with MOT and Insurance etc.

I'd ask the local MOT place and your insurance if there will be any obstacles before going to the effort of a possible wasted venture.
Cheers,
John

If you wanted to go all out, have someone make an adapter for a ZF8HP and go 8 speed auto. You can do lever shift or flappy paddle etc, and they're great boxes.

The original 4 speed would be easier though
