Here's a general outline of the process. This is NOT a substitute for a repair manual:
1. Disconnect the Battery: This is the most important step to prevent electrical shorts.
2. Remove the Distributor Cap and Rotor: Carefully remove the distributor cap and rotor, noting the position of the rotor relative to the distributor housing. You'll need this information for reassembly.
3. Remove the Distributor Hold-Down Clamp: This clamp secures the distributor to the engine. Loosen and remove it.
4. Remove the Distributor: Gently rock the distributor back and forth while pulling it upward. It may be slightly difficult to remove, so use a gentle but firm force. Pay close attention to its position as it comes out. You might need to slightly rotate it to clear any obstructions.
5. Separate the Distributor Gear: This is the tricky part and where a repair manual is vital. Some distributors have a gear that simply slides off the distributor shaft, while others may require more specialized tools. The gear might be held on by a snap ring, a retaining pin, or even pressed onto the shaft.
* If it's a slide-off type: Gently try to slide the gear off the shaft. Sometimes a light tap with a brass punch (never steel) can help.
* If it has a snap ring: Use the appropriate snap ring pliers to carefully remove the snap ring.
* If it's pressed on: This requires a gear puller specifically designed for this purpose. Improper removal could damage the shaft.
6. Inspect the Gear and Shaft: Carefully inspect both the gear and the distributor shaft for wear, damage, or scoring. Replace either or both if necessary.
7. Reassembly: Reassembly is the reverse of disassembly. Ensure everything is properly aligned, especially the rotor's position. Use new gaskets and seals where needed to prevent leaks. Always tighten components to the correct torque specifications as listed in your repair manual.
Important Considerations:
* Timing: You'll likely need to re-time the distributor after reinstallation. This requires specialized tools and knowledge. Incorrect timing can severely damage the engine.
* Tools: You'll likely need a variety of tools including screwdrivers, sockets, wrenches, possibly a distributor gear puller, snap ring pliers, and a brass punch.
* Safety: Always wear appropriate safety glasses and gloves when working on your vehicle.
Again, it's strongly recommended you consult a repair manual specific to your 1989 Dodge Dakota and its engine before attempting this repair. This process is intricate, and mistakes can lead to engine damage. If you're not comfortable with this level of vehicle repair, it's best to take your Dakota to a qualified mechanic.
