ACT Clutch and Flywheel Help

[dustyduff]

I just recently had a new motor, rebuilt trans, ACT 2600 clutch, and ACT lightened flywheel installed in my car. The car runs great, but I hear a light high frequency rattle coming from the tranny where the clutch and flywheel are. It comes and goes while the car is idling (for the most part, it comes and stays). When I press the clutch in, it goes away and when I release it, it comes back. Anyone have any suggestions or ideas on what this might be, so I can have the guy who installed it check it out for me?

During the clutch/tranny install, I replaced the slave cylinder, master cylinder, throw out bearing, clutch fork, pivot ball and waiting on my slave cylinder extension rod.

I have the exact same problem with my car right now. I also have the ACT 2600. I've been told its the throwout bearing for mine.. but no one is really sure. Wish i knew what it was..

Someone mentioned that the throwout bearing may be my problem too. A new one was supposed to have been installed when everything else was put in. I don't know if the guy installing it accidentally forgot it. Did you do the lightened flywheel too?

Imagine this... I have the same problem. It's the throwout bearing. Rest assured you need a new one.

I'm praying that the rattle is just due to the throw out bearing, because I haven't even driven the car yet, except to move it in and out of my driveway. It would be pretty sad to have a failing clutch with 0 miles on it.

Did you use the new throw out bearing that came with the act kit? if so make sure it was a plastic oem style TOB. they used to to metal sleeved throw outs and that causes alot of these kinds of probs...i would check that out first

 

[dustyduff]

I think it was the OEM bearing. I ordered the kit from Slowboy Racing about month and a half to two months ago.

did you know that when you get a new or rebuilt trans , when you first start it up you should drive it or rev it up to like 3k for a little bit to lubricate all the parts in the trans because some things dont get lubricated from just idling.

I used the one that came with the kit and it was the OEM style, there is always a grinding noise when I push in the clutch, I then replaced it with a sleeved one like you are talking about and now the clutch basically wont disengage. What about the sleeved one will cause this?

Eventually the metal sleeved TOBs will make a groove in the collar around the input shaft and the TOB will start binding up because it cannot slide properly.

Well I just took off my tranny and the clutch is fine so its got something to do with this sleeved TOB. I noticed something about it, the bearing surface on it dousn't stick out as far as on the one that came with the clutch. I think the grinding sound was the outer sleeve of the TOB rubbing on the fingers of the pressure plate because it was less so with the TOB the clutch came with. I think Im going to buy the original Bishi bearing it had in the first place as the bearing surface stuck out alot on that one so there is no way it would rub. So the original didnt rub, the ACT rubbed allitttle but still worked and the sleeved one worked like sh#t and did nothing. The strange thing is though that I didn't see many scratches around where it would have been rubbing so Im not sure if that theory is right or not. Im going to check the stepping on the flywheel, I told them .612 but maybe they screwed it up. Im not puttting this thing back together until I KNOW the problem is fixed.
