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.
