The MEC 650 is a popular choice among reloaders for its robust design and ability to handle a high volume of shells. However, like any mechanical device, parts can wear out or break. Understanding the various components and where to find replacement parts is crucial for maintaining the efficiency and longevity of your MEC 650. This guide provides a breakdown of common MEC 650 reloader parts, troubleshooting tips, and resources to keep your reloading process running smoothly.
Understanding MEC 650 Components: A Closer Look
The MEC 650 is comprised of numerous interconnected parts, each playing a vital role in the reloading cycle. Knowing these parts will help you diagnose problems and order replacements accurately. Key components include:
1. Frame and Housing:
- The main frame provides the structural base for all other components.
- The powder measure housing encases the powder measure mechanism.
- Case bushings: These guide the shell cases through various stations. Different bushings accommodate various shell gauges.
2. Powder Measure System:
- The powder measure itself is critical for consistent powder charges. Various styles exist, each requiring specific maintenance and adjustments.
- The powder bar regulates the amount of powder dispensed.
- Powder measure adjustment knobs: These allow fine-tuning of the powder charge.
3. Primer System:
- The primer feed system delivers primers to the shell. This often includes a primer slide and primer tray.
- The primer seating mechanism firmly seats the primer into the shell.
4. Shell Plate and Case Feeding:
- The shell plate rotates, advancing the shell through the various stations. It requires proper lubrication for smooth operation.
- The shell retainer holds the shell in place during the reloading cycle.
5. Crimping System:
- The crimp starter begins the process of crimping the shell.
- The crimp head completes the crimp, ensuring a secure seal. Different crimp heads are available for various shell types.
6. Other Essential Parts:
- Handle: This is the primary control for operating the machine.
- Springs and Pins: Various springs and pins are crucial for the proper functioning of different mechanisms.
- Bolts and Nuts: These secure the various components.
Troubleshooting Common Issues and Part Replacement
Identifying faulty parts is often the first step in repair. Here are some common issues and their potential causes:
- Inconsistent Powder Charges: This may indicate a problem with the powder measure, its adjustment, or the powder bar.
- Primer Misfeeds: Check the primer feed system, tray, and slide for obstructions or wear.
- Crimping Issues: Examine the crimp starter and crimp head for damage or misalignment. A worn crimp head is a common culprit.
- Shell Jams: This might be due to worn-out case bushings, a misaligned shell plate, or a problem with the shell retainer.
When a part needs replacing, obtaining genuine MEC parts is highly recommended. Using non-genuine parts could compromise the machine’s performance and safety.
Sourcing MEC 650 Reloader Parts
Several reputable suppliers provide MEC 650 parts. You can usually find these through online retailers specializing in reloading supplies or directly from MEC’s authorized dealers. Always verify the supplier’s authenticity to avoid counterfeit parts.
Maintaining Your MEC 650 for Optimal Performance
Regular maintenance is key to extending the life of your MEC 650. This includes keeping the machine clean, properly lubricating moving parts, and inspecting components for wear after each reloading session. Preventative maintenance minimizes downtime and keeps your reloader performing reliably.
By understanding the various parts of your MEC 650, you’ll be better equipped to troubleshoot problems, perform necessary repairs, and keep your reloading operation efficient and safe. Remember, always consult the official MEC 650 manual for detailed instructions and safety guidelines.
