Here's how to remove and install the distributor:
Distributor Replacement
At AskMeHelpDesk.com, over 50% of new aftermarket distributors for Hondas have not worked out of the box. Many of those that initially worked didn't last very long. Therefore, I only recommend genuine Honda distributor housings. It's fine to buy a Honda housing and install an aftermarket Ignition Control Module (ICM) and coil, to keep the cost down. Three reasons account for the majority of Honda distributors needing replacement: orange dust, oil inside, or failed sensors.
1. Disconnect negative battery cable, after recording radio code.
2. Remove #2 Phillips head screw, securing 2-P and 8-P connector mount to the side of the distributor, using a precision screwdriver. Access is often improved if the air filter cover is removed first, using an 8mm nut driver. Separate 2-P and 8-P electrical connectors. The trick to separating these connectors is to squeeze the connector's mounting release first and remove from mount. Then, the connector will separate--do not force.
3. Mark distributor housing and bracket, for timing to be close later, using a scribe (or awl) and straight-edge.
4. Remove three hex-head machine screws, securing distributor cap to housing, using an 8mm nut driver.
5. Move distributor cap and wires off to the side.
6. Remove machine screw securing rotor to shaft, using #2 Phillips head screwdriver, and leak cover. It may be necessary to "hit" the starter once or twice, in order to rotate rotor for access to mounting screw.
7. Remove three 12mm bolts securing distributor housing to engine.
8. Remove old distributor, place on table, and remove coil, igniter, and cap seal.
9. Install old igniter, coil, leak cover, cap seal, and rotor in new distributor. Ensure female igniter terminals fit snugly--crimp with pliers, if necessary.
