McLeod Twin Plate Part Number

[debaron]

Decided on McLeod twin plate clutch for my supercharged project.

Can anyone advise the right part number and where to get hold of please?

Would like to use my existing lightened Rover V8 flywheel


450 HP estimated at crank

Thanks

Excellent choice, handled my 573hp/610lb torque well enough. I'm afraid I can't supply the part number as I gave all receipts/records when I sold my car. All I can say is measure, measure and measure again the throw out bearing (thrust bearing) carrier against flywheel face and have milled to suit (costs pence). Fine adjustments can be made if necessary to slave cylinder position allowing distance for plate wear. If using your existing flywheel you will need to get it drilled to suit and then balanced with whole assembly for proper job.
Some have had differing experiences with them but I can only say that mine was a delight as others who tried it testify to. Good luck

Real Steel keep only one twin plate clutch in stock for the Rover engine, just remember that you need friction plates for a 1 inch metric splined shaft, (can't remember how many splines but they will know).

Mine bolted direct to my aluminium flywheel which I believe is a MacLeod item.

As Mac said, you will have to have yours drilled and balanced.

As for the machining of the carrier, mine didn't need any when the clutch is matched to the MacLeod flywheel .

My clutch feel is effing heavy so I've just fitted a servo in the system. Macs doesn't seem to be and I have no idea why!

Try Brian at Roadcraft, I've just ordered 10.5" twin plate McLeod with billet flywheel

I would of solved this....the idea of the twin plate is to make it feather light and handle power Twice the surface area you dont need the huge clamping force as with single plate clutch. Macs was feather and I mean feather light. The servo will sort it I have one but feel your masking the problem. I have a 950ftlb paddle in mine and it used to snap my leg now with clutch servo effortless

I understand what you are saying Neal but I’m not masking the problem.

My insisting single plate Mcloyd clutch was very heavy. Heavy and rated at 350 BHP.
Twin plate, same heavyness rated at 800 BHP.

Twice the surface area and can handle more than twice the power.

Stands to reason that it isn’t going to be light.

Shut it!

In all seriousness, yours may have had a different pressure plate to mine? They all look the same and may have been supplied wrongly which wouldn't be a first!

[macdeb]

It's a puzzle for sure, I tried a twin plate McLeod (800hp, same as mine) on another car before buying mine and that was also light hence me going for one.

[phazed]

Maybe they supplied me with the clutch plate capable of handling 1600 hp!

Its a shame we cant get those part numbers, Mac's clutch was indeed a light and fantastic feeling thing. Admittedly I just sat in the drivers seat with the car stationary and dipped the clutch a few times, but it was light and the resistance was extremely progressive feeling throughout it's full stoke, in my experience this consistency of resistance as you let the pedal up is something most Chimaera clutches lack.

There was also a very satisfying and definite metallic stop at the end of the travel, which was probably nothing more sophisticated than a well adjusted pedal stop bolt but I have to mention this because it gave a really lovely positive feel when the pedal was fully depressed, the result being a reassuring confirmation you'd fully disengaged the clutch.

After my very heavy Helix debacle that ended in a dragging clutch which in turn eventually burnt my brass 5th gear syncro ring (never again), I now have an AP clutch which is fine, but I have to say in terms of weight and especially feel it's not a patch on Mac's twin plate McLeod. The truth is in power terms I'm a very very long way off needing a twin plate McLeod, but I'd still love one just for the progressive feel and weight alone but only if I could be sure it would end up exactly like Mac's.

Sadly it seems from Peter's experience there are either different cover plates being supplied by Real Steel, or more likely to my mind.... there are master/slave cylinder bore differences between the two cars? One thing is for sure, there was absolutely no need for a clutch servo on Mac's car, my 80 year old mum could have operated it, whether she could have handled the immense power of the engine is a completely different story

What a shame we can't confirm those McLeod part numbers Mac...

I can't help with part numbers either. Mine was a chevy item rated at over 1200 hp, lbs/ft etc. I bought it direct from Mc Leod and was told to specifically ask for the pressure plate with 3 levers as opposed to the multiple fingers. It was as light to use as any other 'normal' road clutch. A pleasure to use especially when stuck in stop start traffic.

Fitting the pressure plate to the flywheel meant tapping and drilling slightly into the ring gear. I also had to make 3 clearance holes in the bell housing because of it's increased diameter but after that I loved it.

A friend in Sweden's just bought a Mantic twin plate, could be good. maybe worth a look.

TKO 600
PS; I fitted TKO600 box but chose to keep an external slave cylinder as they do fail.

Cheers bloke reassures me I'm not going mad. Other McLeod twin plates I've tried are a delight, some on here have also tried mine and said the same (then bought one). The fact that it was rated at 800hp and managed to handle my 610lb torque ok (few on here will have that) is testament to it's capabilities. Would I but another? without question. I'd say to OP get one. Yes, 'tis shame about part numbers, but I supplied a mountain of receipts to the new owner with that being one. Your point on master/slave/bores could be possible. Perhaps a chat with the manufacturer McLeod? I found them to be very helpful prior to me buying one.
