Understanding the Significance of Timing

Timing plays a crucial role in the operation of any steam locomotive, ensuring that the various components work in harmony to produce smooth and efficient power. In the case of the Accucraft Ruby, precise timing is essential for:

• Optimizing Steam Utilization: Proper timing allows the locomotive's valves to open and close at the appropriate moments, maximizing steam utilization and minimizing energy loss.
• Balancing Power and Efficiency: By fine-tuning the timing, you can strike the perfect balance between power output and fuel efficiency, ensuring that your Ruby performs at its peak while conserving resources.
• Preventing Damage: Incorrect timing can put excessive stress on the locomotive's components, potentially leading to costly repairs and premature wear.

Step-by-Step Guide to Setting the Timing

Materials Required

• Accucraft Ruby locomotive
• Valve setting tool (included with the locomotive)
• Small screwdriver
• Soft cloth

Safety Precautions

• Always wear appropriate safety gear, including safety glasses and gloves.
• Ensure that the locomotive is cool to the touch before handling.
• Disconnect the locomotive from the track and power source.

Valve Setting Procedure

1. Valve Disassembly:
   * Remove the side tanks from the locomotive.
   * Locate the two valve covers on the top of the boiler.
   * Using a small screwdriver, carefully remove the screws holding the valve covers in place.
   * Gently lift off the valve covers to expose the valves.

2. Valve Inspection:
   * Inspect the valves for any signs of damage or wear.
   * Check that the valve seats are clean and free of debris.

3. Setting the Timing:
   * Insert the valve setting tool into the cylinder head.
   * Rotate the valve setting tool until it makes contact with the valve stem.
   * Adjust the valve stem to the specified timing measurements (see Table 1 below).

4. Valve Assembly:
   * Reinstall the valve covers and secure them with the screws.
   * Reattach the side tanks to the locomotive.
