Honda Accord/Prelude 1984-1995 Repair Guide

Parts Replacement


On 1990-95 Accords and 1988-95 fuel injected Preludes, the distributor cap, rotor and igniter are the only serviceable parts in the distributor. If the reluctor(s) or pickup coil(s) are found to be defective on these models, it will be necessary to replace the entire distributor housing.


Distributor Cap and Rotor

See Figures 1, 2 and 3

The distributor cap is retained by screws to the distributor housing. With the ignition OFF , loosen or remove the screws, then remove the cap. Inspect the inside of the cap for cracking, burning or heavy wear on the wire terminals. Replace the cap if there is any sign of anything abnormal. Slight wear on the terminals is normal.

Some models use a set screw to secure the rotor to the shaft; loosen or remove (but don't lose) the screw before attempting to remove the rotor. Remove the ignition rotor by lifting it straight off the shaft. Inspect the rotor for any sign of wear; dressing or refiling the rotor is not recommended except in emergency circumstances.

Fig. Fig. 3: On most models, the rotor can simply be pulled from the distributor shaft

Before installing, align the rotor and shaft; both have a flat side to insure correct placement. Press the rotor onto the shaft. Install and tighten the set screw if applicable. Install the cap and any seal or gasket carefully onto the distributor; tighten the screws just snug.


See Figure 4

  1. Turn the ignition switch OFF .
  2. Disconnect the negative battery terminal.
  3. Remove the distributor cap and rotor.
  4. Use two small or medium sized flat tools to pry the reluctor smoothly and evenly from the shaft. Protect the case of the distributor with rags or cloth. Use great care not to damage the stator or other components.
