All I can say is you're a lucky man, it could have been so much worse.

It is to prevent exactly what has happened to you that Exedy, with their Sports Single lines (Sports Orangic, Sports Ceramic & Race Ceramic) use a anti-burst casting.

faulty batch eh? shame he only told you about the faulty batch after it exploded beneath your left leg. Yes compared to the number of clutches sold there has only been a small number of exploding ones but still, frankly I think 1 is too many and the fact that I know of at least 3 over the last few years tells me something isn't quite right. it sounds like everything should get sorted out though.

agreed, ive made various post over the years in just about every jb clutch thread but its seems people just keep going there.... he must have the gift of the gab.

There is a "shelf" clutch avalable for EVERY application from majors like OSgiken, ORC etc...

My mind is open at this stage baron. I am only passing on what the man said to me via our first phone conversation.

However, if the old adage "Talk is cheap" holds any sway then Jim is one cheap mofo for sure. He could talk the legs off an iron horse.

We'll see what eventuates on thursday when I present the parts to him.

Lets hope to god he can pull some strings and get something reasonable sorted for ya noleskies

It was only last week shane was telling me to get one same as yours :P Might pass on that...

You might have to sue him in order for him to be able to claim on his insurance... might be worth looking into

the man builds thousands of clutches, 3 of them have issues and all of a sudden his clutches are no good.

the man runs a business , has insurance for these sort of misshaps, and will sort it out. Suggest you guys tread carefully or you might find yourselves up for defamation.

^^^^^ Agreed Stuart. Jim does have a business to run, so ill just see what the outcome is before i make judgement. Its such a shame to see this happen though.

Jim certainly can talk; ill never ring him on a mobile again!

Insurance is all good for car parts but no money can fix your body if a chunk flies into your leg

an old high school acquaintance has lost half of his left calf no longer has a fibula bone....nice titanium rod in place of it, and severely shattered tibia from shrapnel flying through the floor when the drivetrain let go...

unrelated to JB clutches but such results could easily occur from this sort of situation........limp for life, can never run again and need a walking stick.....no thanks

theres no dought that you wouldnt wish this on anyone, and yes the matter could have been much more complicated if someone had have been injured. I will definately be installing a scater shield in my car now. i can understand you being well pissed. Give the bloke a chance and hopefully all will work out well. Its the hard way to go about getting an engine freshn up but anyway. Good luck with it.

People should also be aware that the covers and diaphrams used are purchased off the shelf items, they are not fabricated. Its impossible to know that there might be a problem with a cover unless one fails. Jim always explains to me on those long phone calls how he searches for the best quality cover with thicker wall thickness etc to try and eliminate these failures. he definately does not use cheap parts in his clutches. im shore if you asked 10 clutch builders if they had a clutch fail, that most would say yes. this is not uncommon.

Are you feeling alright?

I bet if you lost a leg due to a failure like this you would have a completely different opinion...lets see some insurance grow you one of those back.

If these things are happening then he should recommend the use of scatter shields etc with his cltuches to save some legs. Or not sell clutches. 3 too many i say.

Jim is a top bloke. I have a rebuilt HKS Twin done by him.

Where can I get me some protection? Where to buy shields or bags please?

rocket industries sell them mate, but I am going to just buy a clutch with an anti burst cover in the first place...

Just out of interest what was a rebuild worth on the HKS twin?

There is different types. RCI make a cheap one looks to not be Kevlar and is some steel belted blanket that you strap around it. For about 300ish US they then sell Kevlar blankets. Then for all popular American transes (mostly auto) they sell pressed steel scatter shields. All these go on the outside of the bell housing. With some transmissions you can buy special casings that they do not require a blanket as its built into the metal.

I have met Jim and spoken with him at length.

he takes a lot of pride in his work and knows what he is doing. he is not a hack he is a professional with over 30 years experience. If i was to get a new clutch i would have no hesitation in getting one from him. he does cluthes for v8 supercars, group a rally and all sorts of hipo applications.

if it was a faulty cover or even 3 I am sure he will look into it and do what needs to be done.

I hope it all works out.

No good to hear Noel, no good :rofl:

I was privvy, no I was not driving or was it my car, to a clutch explosion (not JB) very recently in a 34 GTR which ended in a similar tradgedy for the bellhousing.

Do you by any chance think the failure could be put down a previous over-rev of the engine?

I only ask because after asking lots of question to lots of experts, an over-rev that occured within 500 klm prior to the event was blamed. The car I speak of had a "to first" instead of "to third" monent :P

Dude,

Did you recover all of the debris..well whatever was on the road anyway...Can't see the pressure plate itself in the pictures...I assume it is now in 50,000 peices..

It looks to me (from the existing pictures anyway) as if the pressure plate itself has failed first, then ejected peices of itself out through the clutch cover and then through the bell housing...If you have a look at the bolt holes in the clutch cover that are slightly elongated radially outwards indicating that a very high load has been placed on these bolts...The clutch cover also looks pretty much intact apart from the deformation..

The steel straps that normally support the pressure plate have also copped a hiding consistent with bits of pressure plate stilll connected to them travelling outwards with great force...

Also if you post up some pictures of the flywheel showing each of the bolt stubbs still in the flywheel, I can tell you if any of the bolts show signs of fatigue or if they all failed due to overload...

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
