clutch 1965 series IIA - Land Rovers Only

What do the three adjusting nuts on the clutch do? It seems
that they adjust the three arms on the clutch. I measured
the distance from the arms to the throwout bearing and it
was 3/4 of an inch before making contact. So....I adjusted
them so they are about 1/4 of an inch before making contact.
The problem before was the clutch pedal would depress fully
but the clutch was not moving far enough to allow me to
shift gears. After the adjustment the tranny shifts fine but
now the clutch slips real bad. Should I not have messed with
the adjusting screws? Do the screws also provide tension on
the clutch?

The nuts you are refering to are to adjust the release arms, so that the pressure plate is uniformly withdrawn from the friction disc. It sounds, without seeing it, that you have either gone too far, gotten your measurement wrong and the throwout bearing is partially applying pressure to the pressure plate without stepping on the clutch pedal, or you have them adjusted such that it is coming away on an angle, as opposed to moving straight back. As a general rule, these are set up at the time the pressure plate is assembled, and not fussed with afterwards, as it's the friction plate and release bearing that wears out. They don't alter the pressure plate angle in a static mode (no pressure on arms) and the preload is controlled by the springs.
Hate to say it, but you might be best served by starting with a fresh friction plate, pressure plate and throwout (release) bearing. Not a bank breaker in the long run.

Thanx for the help. I took the floors out and the transmission tunnel and the shifter to see if I could adjust them back. Guess what ? .....I could. There is a small panel just behind the shifter bracket that allows a good view of the throwout bearing and the clutch. So I adjusted them back and now all is fine. There is quite a bit of distance between the throwout bearing and the arms on the pressure plate. This slack is taken up after you push the pedal down once. It doesn't take much after that to engage the clutch. I also found out that I have a 9 inch not a 9 1/2..... clutch that is. I will eventually need to upgrade (my engine has 140hp) but for now i'm good to go.

Excellent! As they say, 'All's well that ends well'.
