The Lee Loadmaster is a popular progressive reloading press, known for its versatility and efficiency. However, like any mechanical device, it can occasionally experience issues. One common problem reported by reloaders is an inaccurate or malfunctioning index. This article will delve into the potential causes of Lee Loadmaster index problems, providing troubleshooting steps and solutions to get your press back up and running smoothly.
Understanding the Lee Loadmaster Indexing Mechanism
Before troubleshooting, it's crucial to understand how the Lee Loadmaster's indexing mechanism works. The press uses a cam system to advance the shell plate to the next station after each complete press cycle. This system relies on precise alignment and the proper functioning of several components, including the shell plate, indexing cam, and linkage. Problems in any of these areas can lead to indexing issues.
Common Causes of Lee Loadmaster Index Problems
Several factors can contribute to an inaccurate or malfunctioning Lee Loadmaster index:
1. Shell Plate Binding or Obstruction:
- Problem: A shell plate that's not rotating freely is a primary culprit. This can be due to debris, lubricant build-up, or a bent or damaged shell plate.
- Solution: Carefully inspect the shell plate for any obstructions. Clean it thoroughly, removing any built-up powder, brass shavings, or excessive lubricant. If the shell plate is bent, it might need to be replaced.
2. Worn or Damaged Indexing Cam:
- Problem: The indexing cam is a critical component responsible for driving the shell plate's rotation. Over time, it can wear down, causing inconsistent indexing.
- Solution: Examine the indexing cam for wear, cracks, or damage. If severely worn, replacement is necessary.
3. Linkage Issues:
- Problem: The linkage connecting the indexing cam to the shell plate can become loose, bent, or damaged, preventing proper indexing.
- Solution: Check all linkage components for looseness, bends, or damage. Tighten any loose connections and replace any damaged parts. Ensure all linkage components move freely without binding.
4. Improper Adjustment:
- Problem: Incorrect adjustments of the press's various components can interfere with proper indexing.
- Solution: Consult your Lee Loadmaster's instruction manual for the correct adjustment procedures. Pay close attention to the shell plate alignment and the indexing cam's position. Incorrectly tightened components can also cause issues.
5. Case Length Issues:
- Problem: Using cases that are too long or too short for the die setup can sometimes cause indexing problems by interfering with the shell plate movement.
- Solution: Ensure you're using cases of appropriate length for your chosen dies.
Troubleshooting Steps:
- Visual Inspection: Begin with a thorough visual inspection of the entire indexing mechanism. Look for any obvious signs of damage, wear, or debris.
- Clean the Press: Thoroughly clean the entire press, paying special attention to the shell plate and indexing cam areas. Use a brush and compressed air to remove any debris.
- Lubrication: Apply a thin layer of high-quality reloading press lubricant to moving parts. Avoid excessive lubrication, as it can attract debris.
- Check for Binding: Manually rotate the shell plate. It should turn smoothly and freely without any resistance.
- Test the Indexing: Cycle the press through a few cycles without any ammunition to observe the indexing mechanism's operation.
- Adjustments: If necessary, make minor adjustments to the press components according to the manufacturer's instructions.
- Replacement Parts: If the problem persists, you might need to replace worn or damaged components, such as the shell plate, indexing cam, or linkage parts.
Preventing Future Index Problems:
- Regular Maintenance: Perform regular cleaning and lubrication of your Lee Loadmaster to prevent wear and tear.
- Proper Lubrication: Use a high-quality reloading press lubricant specifically designed for this purpose.
- Careful Handling: Avoid dropping or mishandling the press to prevent damage.
- Proper Case Preparation: Ensure cases are properly sized and cleaned before reloading.
By following these troubleshooting steps and preventative measures, you can resolve most Lee Loadmaster index problems and ensure the safe and efficient operation of your reloading press. Remember, safety is paramount when reloading ammunition. If you're unsure about any aspect of this process, consult a qualified reloading expert.
