About a week ago, i went to pull up to a light and my clutch pedal hit the floor. The pedal got stiff and the clutch woudl not disengage. I managed to limp it home and pulled the tranny out. My clutch exploded, which was no surprise, i got a cheapo reman clutch off ebay (never again) and it was defective. Well i got the new one in to find that it still wont disengage. ive checked everything, the hydraulic pieces have been replaced, the clutch has been triple checked to make sure its right, the pressure plate too. Even my flywheel is new and in good shape. So with all that in mind, the only part i havent changed is my clutch fork. My question is: how hard is it to bend this, and is it possible that i bent it mashing the pedal while the broken clutch pieces were wedged into the pressure plate? Thanks in advance for any help.

I need to add a bit of info that i found today. With the engine i crawled under the car and noticed the clutch fork vibrating. It was moving about 1/8" total. Hopefully that helps some....

I'll post what I've said via email for future searching, and to let others know what we've been through so far:
Me: You should be able to look through the inspection hole in the bellhousing and watch the clutch work. From there you should be able to see what is happening. Without seeing it myself, I can't offer up much more for suggestions because you said everything appears to be working properly (which it is clearly not).
You: i looked through the hole and i can see the fork and bearing pushing on the PP fingers, its moving pretty far, maybe a half inch. It seems like it should be enough. im not sure whats going on but its getting very frustrating. it almost seems like the bearing isnt close enough to the pressure plate or something. Ive got the fork in the groove on it and all. Im out of ideas, im right next to dropping the tranny again just to look at stuff closer.
Me: Disc installed backwards?
You: no. i made sure i didnt make that mistake. just to make sure, the flat side of the disk goes towards the flywheel right? the side that sticks out goes towards the pressure plate?
Me: Sounds right...It only takes about 30 minutes to pull the trans if you have all the tools out and the car on jack stands. Sounds like it is time to do so, assuming the clutch is properly blead and doesn't have any air in the system. I'm not sure 1/2" of movement is enough.
You: well i havent exactly gotten out a ruler to measure, but i have taken the slave cylinder off and actuated the fork by hand and wedged a socket in there to see, it feels like its not pushing far enough forward to disengage completely.... is that pivot thing adjustable? and the fork is supposed to go inside the groove of the throwout bearing right? Ive already had this thing apart and together about 5 times the last 3 days trying to find the source of my issue. im really have no clue what issue im looking for.... i think im missing something stupid... is there a plastic grommet or something over the pivot ball or something?
Me: If it's not pushing far enough, it probably has air in it. The pivot isn't supposed to be adjustable but you can remove it and put a washer or two under it. Just be sure to locktite the pivot back in place so it doesn't rattle loose. Yes, it goes in the throwout bearing groove, no there is no plastic grommet.
You: i dont mean the hydraulics arent pushing far enough, i mean, it seemed like even when i did it by hand, the fork wasnt moving far enough. we're looking at some rain the next few days, but i suppose ill be dropping the transmission again to look through everthing again if i cant figure out why its doing this.
Me: Well, the hydraulics use a lever arm to make a little movement at the cylinder equal a lot of movement at the clutch.
You: ah alright, i hope you dont mind me coming to you for technical stuff, there is hardly anyone around here that knows much about this car. Ill get this problem tracked down eventually, im sure im just missing something. Thanks for all the info you gave me.

I suppose it is possible that you could have bent the clutch fork, though I've never really heard of it happening in this application before. Can you take any pics of everything you're working with?

I wish i could take pics, but i dont have a camera. Maybe ill try to rig something up with a webcam..... It may not help much in this instance, but i got all the new parts at Autozone so you can see them all on their site. Ill see what i can do, maybe one of my friends has one.

Usually a bent fork will cause the clutch to drag or not fully disengage. I have a few hydraulic forks if you need one. Maybe I can take a side shot picture and a few basic measurements. If you need it I'll also sell.
I think it may be best to pull the trans, leaving the bellhousing and all release parts functional. Slide the clutch alignment tool in to hold the disc, then have someone work the clutch and watch through the back of the bell and see whats going on.

Great idea, i think ill do that. I'll be pulling the tranny in the next couple days, so ill let you know what i find when i do. How much are you wanting in case i do find a bent fork? And also can i get some pictures of the fork sitting on a flat surface or something so i can compare mine? I have nothing to comapare it to...... Thanks.

My net here is shotty at best but I'll try to get some pics/ measurements posted for you.
I suppose $10 to your door for the fork if you're ok with that.

What kind of clutch is that?
Only think "out of the ordinary" I see in those pics is a lack of grease on the input shaft. It appears in the pics that the pressure plate forks were all level when bolted to the flywheel?
I just noticed you're in Kansas, what town?

I really have no clue who made this clutch. The stamping on it says something like "Balkin" or "bilkin" and "DK". I tried to find the company online but all i could come up with is DK being a clutch company from Thialand, which is strange because it says "MI" and "USA" around the center. I had Autozone order another one for this car so i could compare them. The spring part looked different but the specs were essentially the same. I'm not sure if the fingers are level when its installed though i can tighten it down again to find out. What if they arent? It would likely explain the vibration in the fork..... I will grease my shaft this time around. And yea im in Kansas, thats why i took such an interest to know where in Ks you were. I live in a tiny town called Pretty Prairie, about 25 miles south of Hutchinson.

That might be a daikin which is pretty standard on mitsubisihi and I remember the "dk" on my conquest and talon clutches along with saying daikin on it.

Well that being a clutch brand someones heard of makes me feel a little better..... Update: With the new pressure plate, the fingers are a little lower on a couple of them and theres a 1/8" gap in all the indicated spots (all the way around though) on the attached picture. On the old pressure plate, the gap is a lot smaller and the fingers are still a little uneven, but not nearly as bad. img.photobucket.com/albums/v673/XBOXCUSTOMS69/IMG_0317-1.jpg

Hmm, I'll have to chew on this one for a little while.

I'm gonna try the old pressure plate again just to make sure, cause it looks closer to being right than the new one does. I'll let you know how it goes.
