Hybrid_From_Hell Posted October 12, 2018 Share Posted October 12, 2018 I have always had problems with clutches as I have always run tuned engines all V8s ! I have tried many options - all "Self Learnt" and had mixed results. When I had the John Eales 4.5 V8 in the 90, it ate clutches and in the end I fitted a 6 paddle ceramic clutch. It was "OK".. Gripped pretty well, ...pedal not much different, ...but pig in traffic in stop start as it turned into a On/Off switch lol All was sort of "Acceptable" until the newer 342 BHP daft Torque 5.2V8 went in.. It ATE clutches, tried some "HD" stuff, junk to be honest more marketing and bullsh1te than anything worthwhile ... so again I went for a new paddle and cover... It slipped under being booted, then gripped, but on heavy down changes and booting or heavy load it slipped before it gripped, so I had to relook at what to fit. I did loads of research, and then happened to end to speak to Ben Williams at Clutchfix http://clutch-fix.co.uk/ who will prob forget more about clutches than I will ever know. £rd generation of clutch building staff means they really know their stuff, what I liked is when I phoned and had a chat, instead of selling me what I asked for Ben explained I was wrong, then explained why I should buy that, then made me understand what I needed, which is rather refreshing. What I learnt is that clutches are more complex than you might think, and a big part of my issue was that the paddle was the wrong route, what I needed was a special centre than they make (serioulsy genuinely HD not "BS HD" and ...a Stronger Cover with much more ability to bothe clamp the plate to the flywheel AND hold it there. What I have now is what is called a "Double Diaphram" / "Dual Diaphram" Cover, with some daft clampability around 500 Ft Lbs. "Experts on forums warned of me needing Bopth feet to operate , no feel, undrivable on the road, the wheels would fall off and the moon fall out of the sky....so I diod sort of quiz Ben who sighed and said "J F Fit it" and don't belive the armchair experts. So I have and I did . And he was right, with me currently have treatment for a yoof based spinal injury I managed to beg the use of a ramp ...so up she goes and some considerable time later Out comes Gearbox and transfer box complete We then found lots of other things that needed doing, but eventually clutch was taken off. And, as Ben said the cover was not clamping hard enough due to the power output allowing the plate to flex and slip... If it looks new that because its done about 200 miles only, cover was wrecked, paddle itself is fine and will be sold on ! so, bring out the new ....... Dual Diaphram means that the cover fingers have a second layer on the inside to give extra clamp, the size shape and length of these Ben calculated for my trucks output so its 100% custome made, and to be honest the price was less than I was expecting too Prepare to go Oooooooooooooooooooooo By now I was feeling a bit like : But some considerable hours later : It was all in a ready for a test drive. WOW ! By God it clamps, its never ever been such a positive solid clutch when it bites you know its engaged. Yes, the pedal is a bit harder, it feels totally different, normal pretty much up to the very last push down where a bit more force is required, but you could esily get used to it with a bit of time. However with a damaged spine I need to look at getting it a bit easier, even the unit before could "Annoy" my back, so I am now going to do some research on servo enabling my unit, and will do a Post on that too when done - its the next job. But, as an aside if you just wnated to help this a Bit being a 1985 unit I could upgrade the pedal to the later TCDi over centre unit, but as I need to have a really light clutch I am going to bypass this and go servo, and as cheap as I can do it too !" For info the later pedal looks like this and is a direct replacement bar needing to drill 1 x hole of the 6 to mount properly ... But in the meantime my Custom clutch from Ben and his team has solved the issue 101%, highly recommended and don't listen to armchair experts, its highly driveable as is and serious quality to boot. Need a clutch - speak to these guys, and bear in mind much of the after market "Branded stuff" is actually made in India and brand stuck on, ie lucas - does not exist - same as intermotot - owed by SMP, same part in different boxes, so much of the clutch stuff out there is nasty branded junk. Buy a clutchfix unit and you get quality and proper advice. Next servo research ! Nige 1 Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted October 12, 2018 Share Posted October 12, 2018 Good to read of a success. You say the paddle is good enough to be sold on, which begs the question, what friction plate did you use? Something nearer standard, or heavy duty standard, or something cooked up specially?

Hybrid_From_Hell Posted October 12, 2018 Author Share Posted October 12, 2018 cover was a standard AP.....not man enough by far for the torque this boots out lol Quote Link to comment Share on other sites More sharing options...
Tanuki Posted October 12, 2018 Share Posted October 12, 2018 Nice!!! I wonder if anyone's ever considered a 'twin plate' clutch for a torquey LR? We used them on things like Sierra Cosworth rally-cars. 2 separate driven-plates fitted to the gearbox input-shaft but free to slide along the splines independently, with an intermediate plate [splined to the pressure-plate] in between the two, so you get double the friction-area. We never killed one, though we were producing enough torque to guarantee Mr. Tremec's gearbox-factory some regular work. Quote Link to comment Share on other sites More sharing options...

It would require a lot of expensive changes. Quote Link to comment Share on other sites More sharing options...

It was the friction plate that has replaced the paddle style plate I was asking about. It's not important to me at this time, I am just curious. Regards.

The ones on a land rover are not. There is not space for a deeper clutch and the splines have no spare space. I'll tell you what. You go and work out a kit and prove me wrong. Great business opportunity for you. Quote Link to comment Share on other sites More sharing options...

daveturnbull Posted November 27, 2019 Share Posted November 27, 2019 Interested to see what you come up with for the servo operation. Redbooster are very spendy. Quote Link to comment Share on other sites More sharing options...

With the right know-how you can build a clutch that will take everything a LR box can take so what's the point in going to the twin plate that can do 800nm?! I'd also rather push my car than fit something from them. Quote Link to comment Share on other sites More sharing options...
