[DeTomaso] ZF issues - couple more questions

[Mike Thomas]

So, being the novice that I am, I'm just considering a couple more
questions, and a possible screw up.

If I were to have improperly hung the throw out bearing carrier (not gotten
the fingers on the arm in the guides but in front of them, or put the throw
out on backwards (that would be a serious FU), would I even have been able
to drive the car?

Also, during the reinstallation process, I had mused about my installation
of a Quella supplied needle bearing type idler bushing, and asked if there
were any issues with putting a small amount of grease behind the bushing at
the end of the crank to offer some additonal lube in that location.  Nobody
that responded, including Jack D, said it was a bad idea.  The needle
bearing has a lip seal on the outer end of the center, but I'm wondering if
some of that grease is sneaking out and has found it's way to the clutch.

All ramblings of an anxious mind.

Thanks again.
Mike

Thanks for taking the time to do that, that's very interesting.  If the
dimensions are as you say, then I may have another problem of which I don't
know.

The clutch does feel to be engaging, but only at the very top of the travel,
much higher than it used to be.  I have no free play at the top of the
pedal, didn't have much before but more than this.  I can only move the
lever arm back about 1.6 mm from the stop.  Even when I completely
disconnect the slave from the lever arm in the bell housing, I don't get any
more free play there than that.  I've been advised that I should get more
like 2-2.5 mm.  Not much granted.  I'm going bleed the clutch again and take
it for another drive.

We'll see.
Thanks all, this is a great group.

Mike,

Let's take a few steps back and look at this.  From you description, it
would appear that the clutch may not be engaging fully.  Do you have any
free play at the slave cyl adjusting bolt?  Is the clutch arm return spring
installed, and is it strong enough to move the clutch arm against the free
play adjusting bolt stop?  If you do not have any free play at the slave cyl
and can't adjust any, then you may have to remove the clutch arm and rotate
it one spline.

I have both a Quella T/O bearing (China) and a National boxed Federal Mogul
1625 bearing (Mexico) in hand.  The total thickness of the 1625 bearing is
approximately 0.070" thicker than the Quella bearing.
That, in itself, should not create a problem.    The center race (the part
that is pressed onto the T/O
bearing hub carrier) of the 1625 bearing is thinner (narrower) than the
overall thickness of this bearing.
The excess thickness of this 1625 bearing is at the back side of the
bearing, toward the transaxle, NOT towards the pressure plate fingers.  The
actual thickness of the center race is exactly the same (give or take a
thou) as the Quella bearing that I have.  The net of all of this is that the
face of these two bearings, when installed, are in exactly the same place.
