How do you adjust the hydrolic clutch on a nv4500? I have to press the clutch all the way to the floor for it to disengage. Any ideas?

You don't.
You must have a new clutch. The friction point will move up as it wears.

sounds like it's time for a BLEEDIN" session, is the slave leaking? they usually don't do that out of the blue, there is probably something broken, or about to be broken. check carefully,clutch disk,pressure plate,and throw out bearing for wear slavecylinder and line from clutch mastercylinder, check the mastercylinder also for leaking /forums/images/graemlins/thinking.gif /forums/images/graemlins/thinking.gif

WEll, the clutch engagmeent is kinda low- I have to press all the way down to get the clutch to dis-engage. I would like to get it to be reasonable higher, and use the forward portion of the clutch pedal.

If you could lengthen the rod on the slave cylinder or move the slave backwards you could do so.
It will move up as it wears anyway.

Some of the aftermarket pushrods are adjustable, just look under the dash and see if the pushrod is threaded. If so, lengthen it. Had this in my truck last time.
MJ if you check this thread again...
I replaced my aftermarket master with a raymold or whatever master from Napa. Had rebuild kits, $10 less than a complete master.
Anyways, pulled the piston out of both, measured the bore as best I could with some dial indicators. Both the stock and the Raymold pistons were the same diameter. Again, as best as I could tell, since the piston sealing surface of the bore is recessed.
Bleed bleed bleed if it pedal is low and not adjustable.
Found an interesting way to bleed the clutch as well. Of ocurse I didn't take notes, so I'm winging it here:
Remove slave from bellhousing, cap off the pretty full reservoir. Crack bleeder, depress the pin that hits the clutch fork as far as possible (Believe I used my fingers) re-tighten the bleeder, and release the pin. I had to repeat that about 4 times and I had a proper clutch pedal.

so are you saying it is your opinion that an aftermarket rebuild kit may work on the stock Girling steel master?
good info
all these parts are very near or beyond the 'obsolete' designation for GM Parts
they will be dumped eventually

In my opinion they could very possibly fit. At least the piston seal. I didn't notice any real wear on the stock master that I pulled from a truck a few years back, and the rebuild kits come with those and the spring...I doubt either *really* need replacing in most cases.
I wanted to stick the new piston/seal assembly into the old master jsut to verify, but I wouldn't do that without cleaning up the old master housing, and I don't have a hone that will do it.
