1. Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Complete Tractor 1100-5109 Tune Up Kit. This kit is specifically designed for 4-cylinder Ford/New Holland 2N, 8N, and 9N tractors equipped with front mount distributors. Proper installation of these components is crucial for optimal engine performance and longevity.
2. Safety Information
Always prioritize safety when working on machinery. Failure to follow safety precautions can result in serious injury or damage to equipment.
- Ensure the tractor is turned off, the ignition key is removed, and the battery is disconnected before beginning any work on the ignition system.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Work in a well-ventilated area.
- Be aware of hot engine components and moving parts.
- If you are unsure about any step, consult a qualified mechanic.
3. Package Contents
The Complete Tractor 1100-5109 Tune Up Kit includes the following components:
Figure 1: Overview of all components included in the tune-up kit.
- Distributor Cap: Protects internal distributor components and directs spark.
- Rotor: Rotates inside the distributor cap to distribute voltage to the correct spark plug wire.
- Points (Contact Set): Interrupts the primary circuit to induce high voltage in the ignition coil.
- Condenser: Prevents arcing at the points and aids in voltage buildup.
- Spark Plugs (4): Ignites the air-fuel mixture in the engine cylinders.
- Spark Plug Wires: Transmit high voltage from the distributor to the spark plugs. Includes terminals and boots.
- Feeler Gauges: Used for setting precise gaps. (Typically includes .015 and .025 gauges).

4. Installation
This section outlines the steps for installing the tune-up kit components. These instructions are specific to 4-cylinder Ford/New Holland 2N, 8N, and 9N tractors with front mount distributors.
4.1 Preparation
- Park the tractor on a level surface and engage the parking brake.
- Turn off the engine and remove the ignition key.
- Disconnect the negative battery cable to prevent accidental starting or electrical shorts.
- Locate the front mount distributor, typically at the front of the engine.
4.2 Removing Old Components
- Carefully remove the spark plug wires from the spark plugs and the distributor cap. Note the firing order or label the wires to ensure correct reinstallation.
- Unclip or unbolt the distributor cap and remove it.
- Remove the rotor by pulling it straight up from the distributor shaft.
- Disconnect the wire from the condenser and the points. Remove the screws holding the points and condenser, then remove both components.
- Remove the old spark plugs using a spark plug socket.
4.3 Installing New Components
- Spark Plugs:
- Set the gap on each new spark plug to 0.025 inches using the appropriate feeler gauge. Adjust by carefully bending the ground electrode.
- Thread the new spark plugs into the cylinder head by hand to prevent cross-threading.
- Tighten the spark plugs to the manufacturer's specifications (refer to your tractor's service manual for exact torque values). Do not overtighten.
- Condenser and Points:
- Install the new condenser and points onto the distributor plate, securing them with the provided screws.
- Connect the wire from the points to the condenser, and ensure the condenser is properly grounded.
- Rotate the engine manually until the distributor cam lobe pushes the points to their widest opening.
- Using a 0.015 inch feeler gauge, adjust the gap between the points. The gauge should slide in with slight drag. Tighten the retaining screw once the gap is set.
- Rotor:
- Align the new rotor with the distributor shaft and press it firmly into place. Ensure it sits flush.
- Distributor Cap:
- Place the new distributor cap onto the distributor housing, aligning any locating tabs or grooves.
- Secure the cap with its clips or bolts.
- Spark Plug Wires:
- Assemble the new spark plug wires with the provided terminals and boots if they are not pre-assembled.
- Connect the spark plug wires to the distributor cap and spark plugs according to the correct firing order. Refer to your tractor's service manual for the specific firing order (e.g., 1-2-4-3 for many 4-cylinder engines). Ensure connections are secure.
4.4 Post-Installation
- Reconnect the negative battery cable.
- Double-check all connections and ensure no tools or debris are left in the engine compartment.
5. Operating
After installing the tune-up kit, start the tractor and observe its operation. The engine should run smoothly, without misfires or hesitation. Allow the engine to reach operating temperature and listen for any unusual noises.
6. Maintenance
Regular maintenance of your tractor's ignition system ensures reliable performance. While this kit provides new components, periodic checks are recommended.
- Inspect spark plug wires for cracks, fraying, or damage.
- Check spark plugs for fouling or excessive wear during routine service intervals.
- Periodically inspect the distributor cap and rotor for carbon tracking or wear.
- Verify the points gap and condition during scheduled maintenance.
7. Troubleshooting
If the tractor experiences issues after the tune-up, consider the following common problems and solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Engine cranks but won't start | Incorrect wiring order, no spark, fuel issue | Verify spark plug wire firing order. Check for spark at plugs. Ensure fuel delivery. |
| Engine misfires or runs rough | Incorrect spark plug gap, incorrect points gap, faulty component, loose wire | Re-check spark plug and points gaps. Inspect all connections. Test individual components if possible. |
| Engine lacks power | Incorrect timing (due to points gap), worn spark plugs | Verify points gap is set correctly. Ensure spark plugs are clean and gapped properly. |
| Excessive arcing at points | Faulty condenser, oil/grease on points | Replace condenser. Clean points with a non-residue cleaner. |
