Need advice from the clutch gurus..

OK, I have a good one...

The parts: I have a new steel flywheel, a new T5z, and a Spec stage 2 clutch and PP with a Ford Motorsports throwout bearing. I also have a hydraulic clutch from Modern Driveline (with the external slave cylinder). Stock bellhousing, clutch fork and pivot, none of which is new.

The problems:
  1. I can't get the clutch to engage until the pedal is very low to the floor. I've adjusted all the slack out of the pedal linkage and the slave cylinder is pushing the clutch fork almost 2" forward. In order to give it more pedal, I've had to adjust in a fair amount of preload, which I'm told by Modern Driveline, is bad.
  2. Mostly on the downshift, but also occasionally on the upshift, it can be very hard to get the trans in gear. At times it grinds, but rarely
  3. When I'm coming to a traffic light, I hear a loud whirring (not grinding).. it sounds exactly like a large fan spinning down, I know it's not my fan because I have an electric fan. It's definitely related to speed because it gets quieter the slower the car goes.
  4. No vibrations to speak of, although it's kinda hard to tell since I have the Ron Morris engine mounts and they're pretty close to being solid mounts
  5. The transmission has done this behavior since I started driving it, I probably have less than 50 miles on the setup


Any ideas on this?

Thanks,

point 3 ; couldn't that be your starter ??? had similar problem.

When you depress the master cylinder ( the one on the clutch pedal ) , is it operating over its entire lenght ??
When yes , is the slave cylinder operating over its entire lenght ?
Maybe its your clutch fork thats too long from its pivot point. ( hope you can understand my bad english explenation )
 
I'm 100% sure that the sound is not the starter... But I might've found the issue.. or at least part of my problem. I went ahead and pulled the transmission yesterday and it seems that when I was installing the transmission, the input shaft caught the edge of the pilot bearing and shoved it into the crank.. so the net effect is that I was running without a pilot bearing. :thu

I'm not sure how that could have caused the issue with the clutch travel, but this could absolutely cause all my other problems. The bummer is that it also caused the pressure plate to burn and did a little damage to the flywheel, but I think the flywheel will be OK.

Live and learn I guess.

In the past , I think you made a mistake by bolting the trans to the engine while there was still a gap between them !!
:char :char
 
Yep.. I agree. I think I'm going to install the bellhousing first then put the transmission in. It's a little easier to maneuver it around that way.

I do hope so but I think your clutch problem isn't over yet. :confu

check our clutch pivot bolt.

I agree. I've already ordered a new fork and pivot bolt, just to be sure. I even ordered some shims in case I need to adjust the pivot a little.
