Removing the distributor cap To eliminate the distributor cap, label sparkplug wires by their cylinder numbers and loosen connecting bolts, taking care not to drop them. Take off the cap that has wires in it. Label all
Spark Plug Wires and match mark the dispensatory to the distributor body (as a precaution). Any shrouds or air intake piping that can prevent removal of the cap should be removed and then the cap hold-down screws are loosened. Fully lift the cap so as not to break the rotor blade and spring. In case of lack of slack in the plug wires, then label them and detach them off the cap. Installation is the opposite process, which requires the location of the square alignment locator to be noted and the hold-down screws tightened with 18-23 inch pounds (2.0-2.6Nm). In the case of the distributor rotor, the cap is removed followed by the pulling off of the rotor off the shaft. Once the cap has been removed, pull out straight on the rotor, until it comes out of the shaft and armature. Installation is the opposite and the locating boss on the rotor is inserted with the hole on the armature and it must be fully seated on the shaft. To inspect, carefully examine the distributor cap of the engine to confirm that there are no damages, wear or corrosions, and in particular at the electrical terminals. Wipe the cap using soap and water, dry using compressed air and examine it in regards to cracks, broken or worn-out carbon button, or tracks of the carbon and replace the compressed air dryer in the event of any problem. Likewise, examine the rotor to see whether it is damaged, worn out, or corroded, especially at the electrical connections. Clean the rotor using soap and water and dry using compressed air and ensure it is free of cracks, traces of carbon, and burns or broken blade or spring, and replace them in case of any of these.
