96 jeep Cherokee Distibutor installation instructions with pictures But must br step for step and very detailed.

Remove all the spark plugs. On the front of the engine the bottom pulley (the harmonic balancer connected to the crankshaft) will have a little notch on the rear edge of the balancer. It may not be visible yet. Locate the timing indicator which is on the block near the 2 o'clock position of the balancer (looking at the balancer from the front). Place a socket wrench on the center bolt of the balancer and turn clockwise until the notch lines up with the "0" mark on the timing indicator. Install the number 1 cylinder spark plug (this is the front most plug). Using the socket wrench on the balancer turn clockwise one full turn bring the notch back to the 0 mark. Pay attention to how difficult it is to rotate the engine the last half of the full turn. If it was as easy as the first half of the turn then make one more full revolution. If it is difficult or impossible to bring the notch to the 0 mark then stop, remove the spark plug and finish bring the notch to the 0 mark. The whole point of this exercise is to find Top Dead Center of Cylinder Number 1 on the Compression Stroke. This is necessary for proper installation of the distributor. If you are unable to find any discernible difference in the last half of both revolutions then something is wrong and you can't install the distributor following these instructions. Assuming you successfully found TDC-Number1Cylinder-CompressionCycle proceed. Look down the hole (with a flashlight) where the distributor will go and you will see a slot in the oil pump. We need to line up this slot so that the bottom of the distributor will slip into it. This is trial and error as follows. Put the distributor cap on the distributor - looking down at the top of the distributor rotate the body so that the fork (which is a part of the distributor that the mounting clamp will clamp to) is at the 3 o'clock position. At about the 5 o'clock position is a spark plug wire connector now on the body of the distributor make a mark that lines up with the center of this connector (again at about 5 o'clock). With the distributor cap off and the rotor installed, hold the distributor over the hole where the distributor goes (but not in it yet) and rotate the body of the distributor so that the fork is positioned directly over the bolt hole for the clamp (the clamp must be removed to insert the distributor). Now rotate the rotor so that metal end of the rotor is at about the 3:30 position and lower the distributor while very slightly turning the rotor from 3:15 to 3:45 position you should feel the distributor gear engage with the camshaft in the engine. Now let go of the rotor and push down on the distributor. If the fork doesn't seat against the engine block then the slot in the oil pump isn't line up with the bottom of the distributor (where you will see a tip like a screw driver blade). Pull the distributor back out and stick a long screw driver down the hold to engage the oil pump and turn it so the slot is somewhere around 4 o'clock and reinsert the distributor following the previous instructions. Eventually you should get the distributor to completely seat against the engine block. Now if the rotor end is not centered over the mark made on the distributor body you must pull out the distributor and repeat the insertion process starting with the rotor positioned more clockwise or counterclockwise as needed. When the distributor is properly installed the fork will be splitting the clamp hole and the rotor end will be centered over the mark made on the body of the distributor. Clamp the distributor in position. Installed the distributor cap. Install the spark plugs and spark plug wires.
