Exedy 400

[Blue07GT]

You know I was thinking maybe it was the pilot bearing, I've heard it doesn't hurt to change it especially since its only like $10, any inisght on this? Does it come with the kit? Thanks.

My kit also came with a new pilot bearing but I didn't change it because my car only has 8k miles on it. I just put a little fresh grease on it while I was in there.

Upon reading this thread, I just called BBR and ordered a new Exedy 500 clutch. It will be arriving Thursday

Alright,

I've done some searching and there isn't a whole lot of info on the Exedy Mach 400 clutch. What are your impressions? Is it a worth while clutch? Can they hold up to hard driving at the strip and on the street?(mostly street). I've got the normal bolt ons, CAI, Tune, CMCV Deletes, UDP's, Short Throw, LT's so I don't need anything like a Spec 3+ which would be way overkilled for my car, I don't expect to be doing anything else for a while, the next mod will be cams. I'm really leaning towards the Exedy as from what I have seen it is a good and reliable clutch. Is there anything you suggest I look out for? Thanks!

I have this Exedy and here is the Thread if you want to read it.

Tiger,

Thats the Exedy 400? Or is it the 500? Your post says stage 2?

 

[KDT]

^^ Not intending to butt in but I believe Tiger has the Mach 600 because of the ratings in the post he linked us to. That is the same clutch that I have and it is awesome. The clutch pedal isn't too much stiffer than stock and the engagement feels great. All I can say is don't let the high rating fool you. It is mild mannered and grips like a mofo.

Anyone do shims when doing this?

Anyone do shims when doing this?

per my pm to you....the shop i visited today recommended a small shim. so i bought a .150 shim from lethal on their advice. i'm not sure it's enough to help or hurt, but it was cheap. they also sell a .750 spacer for $80 bucks...they said all i need was the smaller one though. i'm set up for next week for the clutch swap

That's weird. The part number on mine is EXE-07952CSC (the same as yours) and it is a disk instead of a puck.

 

[KDT]

Ok, now I see. That makes more sense. I replied before your last post.

 

[tigerhonaker]

Anyone do shims when doing this?

No Shims were needed or used because I changed Both the Clutch & Steel Flywheel to Exedy.

My understanding was if I went with the Stock Flywheel then you need a Shim/Shims.

I used a new OEM take off flywheel and I didn't use a shim. I hope I am OK. I told Chandler at Brenspeed what flywheel I was using and he didn't mention any shims. I do know that you need a shim if you use an Exedy disk with the factory pressure plate because it is thicker than the factory disk. That's what Roush does with their P51 clutch. I am almost positive that I read somewhere that no shim was needed if you used the Exedy kit with a factory flywheel. I can't figure out why you would ever need a shim with a clutch and pressure plate that were designed to work together. If I did in fact need a shim, what kind of problems would I be having? Logic would tell me that the clutch wouldn't disengage properly. Right now my clutch feels great. It engages and disengages aprox 1/2 way off the floor and I have a little free play at the top just like the factory clutch had. It seems perfect to me. Am I missing something here? I hope not. I sure don't want to pull the tranny again right now just to put a shim in.

Don't take this as FACT.
My (Opinion) is I think your Clutch would NOT Release Right or ENGAGE correctly.

So if it is all working just fine you are set Pal.

I did not even want to worry about Shimming so I matched it all up with Exedy Complete.

Plus as you read in the Post of mine I also Replaced the Ford Hydraulic Servo.

And went with the FRPP Hydraulic Servo (Steel-Line).

Thank goodness it is all still working just fine.

I HATE clutch problems and I have had my share of them for a variety of reasons.

Well, that makes me feel better...lol I also replaced the cheesy plastic hydraulic line. I went with the JPC braided one. Everything worked out great. By the way, how do you like the lightweight flywheel? I wasn't too sure about it. That's why I did not get it. I know some people don't like them for some reason.

Karl,

Here is the deal on that.
They are not referring I don't think to the Exedy Lightweight Steel Flywheel.

They are talking about running the Aluminum Flywheels.
On the street the Aluminum Flywheel is NOT as easy to take off with from Stops.
The reason is, it has No-Weight to help with the Torque for take off.
Especially with our 281 Cubic Inch 4.6 Engines.
We don't have enough motor to have real high Torque.
So a Steel Flywheel with it's weight helps to off set the smaller engines that don't have a lot of Torque for take off.

Example a 454 Cubic Inch Chevy Engine Stock is so large it has Torque.

Compare that to our Small 281 Cubic Inch Engine.

Major difference in Cubic Inches so the preferred flywheel for a DD (Daily Driver) is Steel for our engine size.

Something that helps greatly with running the lighter Aluminum Flywheels is running Lower Gears in the Rear End.
Example:
Mustangs have like 3:31 stock and if they were changed to 4:10 Gears it
would be much easier to take off with a Lighter Flywheel.

Something else to consider running an Aluminum Flywheel is it is Harder on your Clutch as you have to SLIP it more to take off from a Stop.

Hope this helps with the bigger picture of flywheels on street Mustangs.

Boner! Gonna order the 500 and flywheel on Friday!

Thanks Terry, that makes sense. So I guess that the Exedy steel flywheel is still heavy enough to work well with the 281. When I go forged, I may consider getting one. I have got to buy an 8 bolt flywheel then anyway.

I just did too. It goes in tomorrow. BBR told me that they have Spec, Centerforce, and McCloud (sp?) clutches sitting on the shelf that they cant get rid of and every time an Exedy shipment comes in, they are gone!.

I'm kinda excited to get ahold of it tomorrow and test it out.

Your gonna like it. From what I understand, the 500 and 600 feel about the same. I never really liked the way the factory clutch felt. My Exedy has a firm but not harsh pedal. Maybe 20% stiffer than stock if I had to guess. The engagement is solid and predictable. I can "feel" the clutch operation much better than before if that makes sense. Of course that may have something to do with the JPC braided hydraulic line I put in there with it. I noticed a very slight chatter when I first put it in if I engaged it at low rpm but now that I have about 400 miles on it, that's gone. This clutch is so smooth and easy I have a hard time believing it can handle 650 ft lbs. It's simply amazing to me.
