• Rotor is balanced with a brass blade and stainless steel spring for consistent performance.
• Compatible with high output CD ignition systems, offering versatility.
• Features a spline drive for secure fitment.

Installation Guide

Installation of the ACCEL 59124 Distributor requires mechanical aptitude and specific tools. It is highly recommended that installation be performed by a qualified automotive technician to ensure proper function and avoid damage to the component or vehicle.

General Installation Steps (Consult Vehicle Service Manual for Specifics):

1. Safety First: Disconnect the vehicle's battery before beginning any work. Ensure the engine is cool.
2. Access: Locate the existing distributor. Depending on the vehicle model, this may require removing other components such as the water pump or power steering pump.
3. Marking Position: Before removal, carefully mark the position of the rotor and the distributor housing relative to the engine block. This is critical for correct timing upon reinstallation.
4. Disconnect Wiring: Disconnect all electrical connectors and vacuum lines attached to the old distributor.
5. Remove Old Distributor: Unbolt and carefully remove the old distributor. Be mindful of any seals or O-rings.
6. Install New Distributor: Apply a thin coat of clean engine oil to the new distributor's O-ring. Align the new ACCEL 59124 distributor with the marks made earlier and carefully insert it into the engine block. Ensure the gear meshes correctly with the camshaft.
7. Secure and Connect: Bolt the new distributor into place. Reconnect all electrical connectors and vacuum lines.
8. Timing Adjustment: After installation, the engine timing must be checked and adjusted according to the vehicle manufacturer's specifications using appropriate diagnostic tools.
9. Final Checks: Reconnect the battery. Start the engine and check for proper operation, ensuring no warning lights are illuminated and the engine runs smoothly.

Operating Principles

The ACCEL 59124 Distributor functions as a critical component in the vehicle's ignition system. Once installed and properly timed, it works in conjunction with the engine's computer (ECM/PCM) to precisely distribute high-voltage electricity from the ignition coil to the correct spark plug at the optimal moment for combustion. Its design ensures reliable signal generation for the engine's electronic control unit, which then manages fuel delivery and ignition timing.

This unit is engineered to be compatible with high-output capacitive discharge (CD) ignition systems, allowing for improved spark energy and combustion efficiency, particularly beneficial in performance applications.

Maintenance

The ACCEL 59124 Distributor is designed for long-term, maintenance-free operation under normal conditions. However, periodic inspection can help identify potential issues before they become critical.

• Visual Inspection: Periodically check the distributor for any signs of physical damage, cracks in the housing, or loose connections. Ensure all electrical terminals are clean and free of corrosion.
• Wiring Integrity: Inspect the wiring harness connected to the distributor for fraying, cuts, or heat damage.
• Environmental Factors: Keep the area around the distributor clean and free from excessive oil, dirt, or moisture, which can degrade performance over time.
• Professional Check: If you experience any ignition-related issues, it is advisable to have the system, including the distributor, inspected by a qualified technician.

Troubleshooting

If you encounter issues after installing or while using the ACCEL 59124 Distributor, consider the following common troubleshooting steps. Always consult a professional mechanic if you are unsure about any diagnostic or repair procedures.

• Engine Misfires or Rough Idling:
  • Check spark plug wires for proper connection and damage.
  • Verify engine timing is set correctly. Incorrect timing is a common cause of poor engine performance.
  • Inspect the distributor cap and rotor for wear or carbon tracking.
• No Start Condition:
  • Ensure all electrical connections to the distributor are secure and clean.
  • Confirm the ignition coil is functioning correctly and receiving power.
  • Check for diagnostic trouble codes (DTCs) using an OBD-II scanner, which may indicate a sensor or module issue related to ignition.
• Intermittent Engine Stalling:
  • This could indicate an intermittent electrical connection or a failing internal component. Professional diagnosis is recommended.
  • Check for signs of moisture intrusion into the distributor, especially after washing the engine or driving in wet conditions.

Note: Due to the complexity of modern ignition systems, advanced diagnostics may be required for accurate troubleshooting.
