The above procedure was written for the 91 - 94 Sentra SE-R.
The procedure for the 200SX SE-R is a bit simpler. There is no need to remove
anything on the car, just remove the locknut and go to work. You may need some vise
grips to be able to loosen the locknut, pliers just didn't work for me.
A note on how to adjust the clutch: when the
clutch wears, it grabs higher and higher on the pedal, till it finally slips. What
this means under the hood is that you need to loosen the cable to get it
to grab lower. When you loosen the locknut, you need to add more slack to the cable.
Where should the ideal grab point be? Different
people prefer different things, but from the factory the clutch begins to grab about half
way up and fully grab about an inch from the top. You should be able to press the
clutch with your hand and get about an inch of "freeplay" before it starts to
slip the clutch. The inch of freeplay is strictly by feeling it. If you were
to press the pedal and look under the hood you wouldn't be able to tell. The Nissan
service manual recommends 1/4 inch of freeplay in the cable under the hood. The hard
part is determining a 1/4 inch of freeplay. I prefer to do it by feel, but whatever
is easier for you.
