Clutch explosion
 

Soooo fun story.

I was JDA (Just driving along) and showing my friend what I thought was a potentially loose bolt in the front strut/trans area. We were cruising at about 25mph changing gears and decided to do a small pull, maybe 10-12psi in 3rd gear. I waited for my lag to go away and it pulled moderately and as I went to shift, BWAHHHHHP. No gears, no nothin. Engine revved freely and the clutch slave cylinder was moving properly and shift cables still attached. A small disk like button was sitting by the boot of the trans, telling me my clutch hub had apparently sheared into pieces separate from that of the pucks. It didn't make noise before, during, or after the process but it certainly seems like the only possibility at this point. I will admit to it being a poor quality 6 puck unsprung disk and a fairly heavy duty pressure plate, and aftermarket flywheel and OEM TOB but we'll see soon hopefully what the true damages are... Wish me luck and hope it's only a shitty disk that did me in.

Re: Clutch explosion
 

time to pull the trans

Re: Clutch explosion
 

xtd clutch disc?

Re: Clutch explosion
 

Yep time indeed. I have only had the trans put in with the engine so hopefully this can be done separately from the engine...

Ding Ding Ding bingo. Gonna replace it with ACT 6224004. http://www.advancedclutch.com/6224004

Assuming that's all that's wrong.

Re: Clutch explosion
 

1g or 2g? 1g's are a little easier from my experience. Not a real tough job though either way. You can take the trans out the bottom and keep the engine in. Take off the front passenger crossmember, xfer case, and axles and the rest you should be able to see.

Re: Clutch explosion
 

2G but that's really good to know so thank you, I will give that a shot.

Re: Clutch explosion
 

on a 2g i believe you have to support the engine because there is more motor mounts on the trans then a 1g

Re: Clutch explosion
 

2g has 3 tranny mounts.

Re: Clutch explosion
 

Forgot about that yea. 1g is the opposite, 3 motor mounts 1 trans mount.

Re: Clutch explosion
 

post pics of the damage

Re: Clutch explosion
 

I'll probably have photos tomorrow evening. I already had one piece of button shaped metal, fall out the boot...

The transmission part number is registering with an Evo III so unfortunately this might be a more complex problem than anticipated. More details to come. There is a guy called the clutch doctor in North Branch that I will contact and see if he can fabricate any necessary parts for a cool custom setup but I gotta see the damage first.

Re: Clutch explosion
 

dont mess with random shops there a dozens of tried and true setups out there that will save you tons over a shop, dont make it more complicated then it has to be. i would go with a clutchnet 6 puck sprung. but thats just my opinion

Re: Clutch explosion
 

Agreed. Go with something proven and save yourself the headache.

As for the Evo trans, you'll be fine. I don't know anything about how they mount, but Evo III transmissions are an upgrade. Just do some reading. :D

Re: Clutch explosion
 

I will certainly listen to that advice and stick with a proven setup. I have always worried about breaking springs out of the disks. I want power safely held up to 650/700 HP. I am getting to see how the Evo III's are an upgrade but I'm wondering if the final drive ratio is a problem with the rest of my drive train? I'll do roll out tests etc tomorrow and collect more part numbers. I guess they are just as modifiable and rebuild able...

Re: Clutch explosion
 

the reason i recommend clutchnet is because they are the only disc ive seen that completely covers both sides of the springs, so the springs cant escape like ive seen a million times on different discs. i was going to toss a clutchnet 6 puck in my car but 123abc had his clutch die so i gave it to him as a wedding present. someday ill buy another for me

Re: Clutch explosion
 

I'd go with twack's recommendation, they have springs but are contained so they can't fall out.

Re: Clutch explosion
 

My plan is to run my ACT 2600 pressure plate and a clutchnet disk.

Re: Clutch explosion
 

I certainly plan on taking the advice. Is there a place I should buy them or is direct the only/best way? I did some digging: http://www.jackstransmissions.com/pa...ars-and-ratios

Gives me all the reasons to keep my trans, but I need to make sure the ring gears and differentials are all in the same boat. However: http://www.jackstransmissions.com/pa...-rpm-and-speed

My ratios seem much more along the lines of stock gearing based on speed vs rpm. So until I really tear into things, I have no clue what concoction is really going on here.

My talon was originally an auto, so I can only hope that the people who did the swap were smart enough to match all these components. This doesn't exactly answer why my clutch let go yet, but if a rebuild is in order then so be it. I imagine the input shaft could be worn out and that the vibrations didn't help, along with cheap quality. I can only hope this hasn't hurt my bottom end.

Re: Clutch explosion
 

in all honesty i think your trans is just fine, your clutch was cheap and just let go. unless you find otherwise when you take the clutch out.

Re: Clutch explosion
 

thats alot of hp

Re: Clutch explosion
 

What makes you think you need to replace your trans and not just the clutch disk?

Re: Clutch explosion
 

If the input shaft or bearings are worn, the vibration has been known to obliterate disks. Also, I am unsure if all my gear ratios are correctly matched between components. At this point, trans is halfway out. I spoke with Clutchnet and they quoted me $510 shipped, for a 2600# or any weight higher (so I'm thinking 2900#) and the 6 puck sprung clutch disk. Yes expensive, but I love a nice clutch.

On a side note I drew up how one simple servo motor and V3 Link could transform a 5 speed into a F1 style transmission and I figured out how to program it too but I'll get to that later when I have it all typed out and drawn.

Re: Clutch explosion
 

what pressure plate do you have in there now or is that xtd too?

Re: Clutch explosion
 

FWIW I ran an ACT 2900 pressure plate with a clutchnet 6 puck sprung disc. That combo worked great for me, bought the whole setup from MAP

Re: Clutch explosion
 

You're putting way too much thought into this. Did it drive funky before it let loose? I would just replace the clutch, put it back together and drive it. Maybe give everything else a quick look, but what makes you think you have these weird issues?

Re: Clutch explosion
 

I am running an XTD white stage 4 pressure plate.

Interesting, good to know, I didn't realize MAP sold clutchnet, thanks.

It didn't drive particularly weird no, but I'm not experienced enough to be sure that things like bearing wear etc. I do plan on just a new disk and reassembly and at this point debating the clutch plate until I need more HP capacity. Right now I'm about max HP on the stock trans but I also don't plan on adding any more power than I have until other priorities are taken care of.

Re: Clutch explosion
 

It wasn't something they sold on their site or anything. I called them and told them exactly what I wanted (ACT2900 w/ Clutchnet). They just sourced the parts and got them to me. If you want a similar combo you might not find it on their site, just give them a call.

Re: Clutch explosion
 

Okay sounds good I wondered. I'll definitely call them tomorrow morning! Unfortunately the ACT plates are sold out but maybe I can convince them to separate a kit and sell one. Or I'll see if I can buy a competition clutch stage 5 plate.

Re: Clutch explosion
 

So I am waiting on a call back from MAP. They said they haven't carried any clutchnet nor have they ever been able to get it. I think this is the poor knowledge I get when I don't speak with the senior sales guys there. (There is more to that statement... :nope: ) I digress, I did find out they can get the CC Pressure plates separate from the kits, however they are $280 and not worth it on their own compared to the kit pricing. Also, they apparently are all the same number so therefore all the same # of pressure. Interesting. So they factor the disk material to be their determining factor in the kit's capacity. This gives me confidence in my XTD stage 4 2300# pressure plate if CC uses anything similar. Updates to come. Trans seems 98% fine. :)

Update: I just ordered the clutchnet 6 puck sprung. Woohoo can't wait for a decent disk!

Update: MAP called. Spoke with Oleg as well. Situation handled, parts coming and hopefully sooner than later.

Re: Clutch explosion
 

New goodies finally came. Time to get going!

Re: Clutch explosion
 

Clutchnet disk and Comp PP?

Re: Clutch explosion
 

Yep! The pressure plate runs 2700# and the disk, well, you guys know the disk. I look forward to seeing how well it works and I'm sure it's miles ahead of my old setup. I'm saving the XTD plate for another idea later on...

Re: Clutch explosion
 

Never heard of anyone running that combo, but good luck with it!
