Clutch question

B6/7 S4/RS4
#101

why are we blaming the JHM hardware when we haven’t determined the cause for those guys? JHM sends the clutch flywheel and pressure plate but speedetc. replaced other supporting parts and resolved his issue. Did you miss that post? axel and madison have yet to do what speedetc did I believe

[quote]has to be something but how many cars are you hearing about with issues related to the jhm clutch … even those guys from England were having issues.

I thought horsepower received the full kit but didn’t install it all…he wanted to just use the clutch or the clutch and flywheel, but not the pressure plate, (or something like that) so his issues may have something to do with that. He will chime in eventually.

[quote]i think you are right maybe i can just stick to a part that is reliable ie the intake manifold spacer which from what i heard which may not be true is made by 034.

no idea how that applies to this thread

[quote]i like the whole idea around the lwfw and was/potentially am thinking about getting a stg 3/4 with lwfw from jhm but it does scare me hearing these issues.

ask yourself a question - why are people buying these JHM clutches (or sachs or loba etc.)? Is it because the clutches on these cars just eventually die? So are you scared of the stock clutch? Mick’s stock clutch was destroyed at like 20,000 miles. Does that scare you? Better get that thing out of your car.

maybe just read the thread or other info on the products.

p.s. the ironic part is that about a dozen posts in this thread were made by guys with the clutch and no problems. There are a few hundred other people with the kits and they’re working flawlessly. Of course the squeeky wheel gets the grease, whether it’s a legit complaint or not. And you’re scared.

Here some food for thought. If the car is not going into gear like it should there is a good chance the flywheel bolts have backed out. It will start out as being hard to get into gear like it is a hydraulic issue. Then it will get to a point where it wont go into gear. SO for the guys with issues not going into gear i would suspect that one or more of their bolts have came loose. Now if you have an issue with the clutch not coming all the way back up then id suspect a hydraulic issue with either the slave or master. Could also be heated up fluid that has broken down. The cheapest thing to change would be to try doing a fluid flush and make sure you bleed it properlly. Then if that doesnt work the look into the slave and line. ANd keep on going on from there.

As the owner of TTS I am working with JHM in a professional manner to try and isolate and resolve the issues I have with my JHM clutch. I am at this time waiting for a reponse to my last questions and suggestions. My JHM clutch was fitted complete, not parts. The LWF, friction disc and PP unfortunately the release bearing they sent was the wrong one even though I gave them my VIN number but this has nothing to do with the issues I have.

#104

That is correct. Way too early to determine what the problem is. The plan (for me) is to replace the slave cylinder, the line between the master and slave cylinders and the fluid (obviously).
The fluid will be RBF600 since I need high temp brake fluid anyway.

As for me being supercharged, yes, I have more power but the tune still hasn’t gone all out. It’s still a conservative tune so the amount of power isn’t huge yet.

Oh and one last thing, the clutch itself is working just fine. I drive it every day, just got back from a road trip during easter weekend, etc. The problem is that the PEDAL isn’t coming back up properly when I PUNCH it all the way to redline. And even then, the clutch itself is still working, it’s just that my entire pedal’s throw is reduced to an inch instead of the full regular throw. The clutch still engages just as it should etc. With all of these symptoms, the first thought is a hydraulic issue. I have no issues getting into any gears, etc. We’ll see soon enough though and I’ll update the thread of course.

@swensa - per saki’s comments I wouldn’t fear the JHM setup. I ran the setup hard for approximately 30k miles before having an issue. While I cannot pinpoint the root cause of my issue, it has been working flawlessly since the last bit of work. I am still running the JHM parts, but do have a new slave, master and TO bearing (still the standard part). My issue could have been hydraulic related and the multiple times bleeding the system resolved it, but it is hard to say since other parts were changed out. End of the day, the base parts remain the same.

#106

Update: My mechanic replaced the fluid, the line between the master and slave cylinder and the slave cylinder itself. Unfortunately, this hasn’t fixed the problem. :frowning:

My mechanic is going to be contacting JHM directly to see if they have any suggestions but this is really strange. The symptoms seem like it’s hydraulic but the only remaining hydraulic piece of the puzzle that hasn’t been swapped is the master cylinder. Everything else has. Really strange and annoying seeing as it’s only happened to 3 of us (i.e. not many people to go to). My mechanic and I would rather not have to go into the tranny but we’re running out of options…

#107

Another update: I’m now hearing a metallic spring like noise when I push the clutch pedal in and out. The same noise if you took a spring and pulled on it and let it go back over and over again.

Seems to confirm the release/throw out bearing culprit (which is what ended up fixing Speed’s clutch problem).

Thoughts?

#108

I’d kinda been holding off until someone else dove in, b/c this is something I’ll probably be doing on my garage floor solo, and I just don’t have the time right now.

I was really thinking hydraulic earlier, and almost bought a new slave, line, & master. But I’ve held off under the suspicion that it was the throw out bearing as well. Right now I’ve been working on other stuff and just driving the jeep though.

#109

Sorry, I am a little late to this thread. But for what it’s worth I have a B7 S4 supercharged with a stage III clutch, all installed by JHM. I have had zero issues with my clutch

#110

Hey cks. How’s it going with your avant?

#111

Solid. Although since it’s my DD, to be honest, I didn’t need the clutch. As you know, I’m not a 1/4 mile guy, so I don’t get into it until I’m in gear anyway. And it’s a little harder to drive, so a skoootch annoying for a DD, and I live in snow 6 months of the year. Should have done the IM and spacers instead… Still sorting out the tune - contributing data to the Count and getting new tunes every few months.

I added a trailer hitch, and plan to convert the roof rack to whisper bars and a box- cleaning it up a little. Next up is new 19" summer wheels/tires. I think I’ve narrowed it down to either Forgestar/VMR and Peelers. Well actually, next up is to have a baby in 3 weeks. Then maybe get new wheels.

All is good, car is super fast, and as you know the avant looks incredible. Four friends have bought Audi’s recently based on my car: Two B8 A4 Avants, a B8 S4, a B7 RS4, and two allroad A4s on order.

This comment is really only for those seeking explanations and not seeking to make more excuses (ie saki). I also had issues with getting into gear. Once everything was torn down it was proven that no bolts had backed out and loctite was used. My clutch was also determined, by JHM, to show normal wear which is why reinstalling it was suggested. I guess anyone trying to really figure out what’s going on can add that info to their files. Also, I noticed the shuddering on the start of the second lap of my first session at the track day. For all those familiar with how HPDE’s work, the first lap is under full caution to allow the equipment to get up to temp. This means a max of around 80mph with me keeping revs below 7k. Also coasting through corners as opposed to aggressive downshifting. Most of this activity would be consistent with normal daily driving. I hope someone figures it out so I can send saki a pair of my dirty draws so he can kiss them and accomplish the first ever international ass kissing.lol

#113

I thought you were coming up to race me for $5000?

#114

The last time we spoke u ain’t have the balls to race me for money. Started whinning about some lame “gentlemans wager”. If that has changed then I accept the race!!

#115

lol go take your meds and beat it…

HAHAHAHAHA … Exactly what I thought. Make a smart comment, get called out. EXCUSE EXCUSE EXCUSE. That’s the saki I know. Don’t make comments to me about racing when ur vaj still can’t handle it.

#117

So you didn’t actually find out the root cause of the vibrations? In a situation like this I would want to know exactly what caused the problem before spending the money to put it all back together. What parts did they replace?

#118

I don’t exactly see where you called me out? You challenged me to some ridiculous $5000 dragrace with a dozen conditions etc. even though I never challenged you to shit, and I have a stock car. You never planned on coming to fucking Canada for a dragrace. You’re just bluffing like a bigshot. Just as you bluffed your challenges to Euroswagr and richib86 and 91gl…alll of which you have backed out on once they agreed to thrash your barely modded RS4. You never intended on following through on any of it.

You want to talk about what I can or can’t handle at the dragstrip? Lol. I’ve got 30 passes in my Rs4. I have the stock record, which is 4 tenths faster than your time you ran with a bunch of modifications. Notice that nobody is questioning my ability behind the wheel but you? That’s the sound of psychosis setting in to your brain.

Go back to shifting at 8250 rpm in your street races with your BMW buddy and jabroni in his badbluers4. Stop polluting these forums with clutter and noise. PM me if you want to yell and scream like a maniac. Save the forums from the garbage

#119

I’m not bluffing. Accept and we can both send our $5k to a Canadian attorney for escrow who neither of us know. I don’t show up, you get my $5k. Seems pretty simple. I suck, clearly. So you can just teach me a quick lesson. But you can contact me offline if you are serious. This thread has nothing to do with dragracing. Mute…

#120

Iirc they sent him a whole new clutch kit and are still testing the parts to find out what’s wrong.
