If you own an Accucraft Ruby, you know how vital it is to keep your locomotive running smoothly. One of the essential aspect is how to set the timing on a accucraft ruby. Proper timing ensures your engine operates efficiently, providing a better performance on the track. In this article, we’ll explore how to set the timing on an Accucraft Ruby, guiding you through each step of the process.
Understanding the Accucraft Ruby
What is the Accucraft Ruby?
The Accucraft Ruby is a popular model steam locomotive known for its intricate design and reliable performance. It is often favored by hobbyists for its ability to provide a realistic steam experience. However, like any finely-tuned machine, it requires regular maintenance to keep it functioning optimally. One of the most critical maintenance tasks is setting the timing, which directly affects how well the engine runs.
Why Timing is Important
Setting the timing on your Accucraft Ruby is crucial for several reasons. Proper timing ensures that the steam valves open and close at the correct moments, which maximizes efficiency and power. Incorrect timing can lead to poor performance, increased fuel consumption, and even potential damage to the engine. Therefore, understanding how to set the timing on an Accucraft Ruby is an essential skill for any owner.

Tools You Will Need
Before you start the process, gather the necessary tools. Having the right equipment will make it easier to set the timing accurately. Here’s a list of items you will need:
- Screwdriver (typically a flathead)
- Wrench or pliers
- Stopwatch or timer
- Fuel (coal or gas, depending on your model)
- Lubricant (for maintenance)
- Instruction manual (for reference)
Step-by-Step Guide: How to Set the Timing on a Accucraft Ruby
Step 1: Prepare Your Locomotive
Start by ensuring your Accucraft Ruby is clean and well-lubricated. A clean engine will function better and make it easier to assess the timing settings. Here’s how to prepare:
- Clean the Engine: Wipe down the exterior and remove any dust or debris.
- Check Lubrication: Ensure that all moving parts are lubricated according to the manufacturer’s recommendations.
Step 2: Access the Timing Mechanism
Next, you need to access the timing mechanism on your Accucraft Ruby. This usually involves removing a cover or panel. Follow these steps:
- Locate the Timing Cover: Refer to your instruction manual to find the timing cover.
- Remove the Cover: Use the screwdriver to carefully unscrew and remove the cover.

Step 3: Understand the Timing Settings
Before you can set the timing, it’s essential to understand how it works. The timing mechanism on your Accucraft Ruby controls the steam valves. You’ll typically find a series of gears and levers that regulate the timing.
- Identify Key Components: Familiarize yourself with the key components, including the crankshaft, valve rod, and timing gear.
- Check Existing Settings: Take note of the current settings, as this will help you understand how to adjust them.
Step 4: Setting the Timing
Now that you have access to the timing mechanism, it’s time to set the timing on your Accucraft Ruby. Here’s how to do it:
- Rotate the Crankshaft: Slowly turn the crankshaft to the desired position, usually marked in the instruction manual.
- Adjust the Timing Gear: Depending on your engine model, you may need to adjust the timing gear to align with the crankshaft.
- Use a Stopwatch: While rotating the crankshaft, use a stopwatch to time how long it takes for the steam valves to open and close. The ideal timing will be specified in your manual.
Step 5: Fine-Tuning the Timing
After making initial adjustments, fine-tuning the timing is essential for optimal performance. Follow these steps:
- Recheck Valve Movement: Ensure that the steam valves open and close smoothly without sticking.
- Make Incremental Adjustments: If the timing seems off, make small adjustments to the timing gear and recheck the valve operation.
- Test Run: After adjustments, perform a test run to see how the locomotive performs. Observe any unusual sounds or behavior.
Step 6: Reassemble the Locomotive
Once you’re satisfied with the timing, it’s time to reassemble your Accucraft Ruby. Here’s how to do it:
- Replace the Timing Cover: Carefully reattach the timing cover, ensuring it’s secure.
- Check for Loose Parts: Make sure there are no loose screws or components that could affect performance.
Step 7: Perform Regular Maintenance
Setting the timing on your Accucraft Ruby is just one part of overall maintenance. Regular upkeep will help prolong the life of your locomotive. Here are some maintenance tips:
- Lubricate Regularly: Ensure that all moving parts are lubricated according to the manual.
- Clean After Each Use: Wipe down the locomotive to prevent dirt and debris buildup.
- Check for Wear and Tear: Regularly inspect components for any signs of wear that may require replacement.

Troubleshooting Common Timing Issues
Problem: Engine Runs Rough
If your locomotive runs roughly, it may indicate a timing issue. Check the timing settings again and ensure everything is aligned correctly. Additionally, ensure the steam valves are functioning properly.
Problem: Steam Loss
If you notice steam loss during operation, it could be related to improper valve timing. Revisit the timing adjustments, and ensure that the valves open and close at the correct intervals.
Problem: Reduced Power
If your Accucraft Ruby lacks power, the timing might be off. Perform the timing checks and adjustments again, ensuring the crankshaft and timing gear are properly set.
