Why won't a new clutch on a 1993 jeep wrangler engage?

Answer 1

The clutch may have been installed incorrectly, but the most common reason is that the clutch cylinder needs to be bled, replacing the clutch on the 4 cylinder requires disconnecting the slave from it's lines.

the bleed valve is at the top of the bell housing opposite side of where the line enters. The procedure is the same as for brakes, loosen the bleeder, push the clutch pedal down and either air or fluid or a combo of both will come out, with the pedal down tighten the bleeder and then pump the pedal, hold the pedal and repeat opening the bleeder, keep doing this over and over until no more air comes out. Remember to keep the reservoir full, and never forget to hold the pedal down until you have tightened the bleeder.

This is all accessible from the panels around the shifter on the inside of the cab.

A quick trick I learned for doing it yourself is to attach a tube to the bleeder about a foot long that points straight up or into a catch bottle with the end of the hose sitting below the level of the fluid, you can then repeatedly pump the pedal without tightening the bleeder, you will go through a lot of fluid doing this but it is easier for one person to do, once you've pushed the pedal 10 or 20 times tighten the bleeder and you should have good pedal.
