Nissan 22100-21P02 Distributor Assembly

Some restraint is called for when dealing with the distributor cap or rotor; while cleaning either of them, one ought to only use cleaner on the part; they should not be in the vehicle because there is a crank angle sensor located under the rotor that ought not to have any contact with any chemical. Despite the fact that the breakerless distributor is easier to maintain as compared to other types of distributors, it is recommended that it be checked from time to time as well as plug wires. To perform this, one has to firstly unplug the ignition coil lead from the coil then unscrew the two nuts that hold the distributor cap in place on the distributor body. Position the cap aside stowing the spark plug and coil wires still connected, in a position in which it will not fall off, maybe by using a wire or tape. Then, to facilitate the bending of the blade, install a new set screw in place of the old one in the base of the rotor, which can be hammered out, and before doing so, examine the rotor on both ends by shining a light into it: the seams may be cracked, and the metal contact at the top will look burnt if it is bad; in this case, replace it. When fixing the rotor it is necessary to tighten the set screw and check for cap cracks or other mechanical damage and inspect the inside of the cap contacts, slight scoring of these is acceptable any doubts on the serviceability of the cap should it be replaced. Last, replace the cap back and lock it with the two screws which are at the two ends of the hold-down then reconnect the ignition coil wire to the coil.

Disconnect the negative battery cable at the battery and place the cable out of the way to prevent accidental contact with the negative terminal. Remove the two retaining screws, take off the distributor cap and position it out of the way. Mark the relationship of the rotor to a fixed point on the engine. Disconnect the distributor electrical connector on the right side of the engine and work the wire from under the intake collector. Disconnect the ground wire on the side of the distributor. Mark the relationship of the distributor housing to the engine block and remove the distributor hold-down bolt. Lift straight up on the distributor to remove it from the vehicle. Before installing the distributor, check the rubber O-ring on the shaft and replace it if it is not soft and pliable. Insert the distributor with the rotor about 45° from the alignment marks so the distributor will line up with the mark when the distributor gear meshes into the drive gear. Reverse the remaining removal procedures for installation. If the engine was rotated, set the engine at TDC for the number one piston. Locate the alignment marks on the rotor shaft above and below the drive gear. Align the bottom mark with the protruding mark just above the drive gear and insert the distributor. Once the distributor is installed and the rotor is in place, the rotor should be pointing toward the number one cylinder. Confirm this and tighten the distributor hold-down bolt.
