Sourcing Parts for the 1989 Mitsubishi MS180LC Excavator: Challenges and Solutions
#1
The 1989 Mitsubishi MS180LC is a robust machine that has been used in various heavy-duty applications over the years. Like many pieces of older construction equipment, finding replacement parts can become a challenging task due to the age of the machine and its potential discontinuation by the manufacturer. Whether you are a contractor trying to keep an older machine running or a technician servicing a fleet, sourcing the right parts for the MS180LC requires a strategic approach.
Challenges of Sourcing Parts for Older Machines
As machines age, sourcing parts can become increasingly difficult. For older models like the 1989 Mitsubishi MS180LC, parts availability can be impacted by several factors:
1. Discontinuation of Parts by the Manufacturer
Manufacturers often stop producing parts for older models to focus on newer machines. This means that once a certain machine model is no longer in production, the parts required for its upkeep are no longer available through official channels.
  • Solution: Aftermarket suppliers or third-party companies may begin manufacturing compatible parts, but availability will vary by part and model. For the MS180LC, searching for both genuine Mitsubishi parts and reliable aftermarket options can help ensure that you find what you need.
2. Limited Dealer Support
Mitsubishi construction equipment dealers may not always stock parts for older models like the MS180LC. In some cases, the parts may need to be ordered directly from the manufacturer or sourced from secondary markets.
  • Solution: Working with an experienced parts dealer or repair service that specializes in older machinery can provide valuable guidance. These dealers often have connections with secondary markets or international distributors who might still have the required parts in stock.
3. Aging Technology and Components
The MS180LC was built in an era when some parts and technology have since evolved significantly. Electronic components, hydraulics, and engine systems may no longer be the same as those found in modern machines.
  • Solution: Consider the possibility of upgrading certain components to newer versions that offer improved performance, efficiency, or reliability. Consulting with a skilled technician or service professional can help you determine the best course of action.
Sourcing Parts: Where to Look
While finding the right part can be difficult, there are several avenues you can explore to get the Mitsubishi MS180LC back in working order.
1. Mitsubishi Parts Dealers and Distributors
One of the most reliable sources for parts is the official Mitsubishi dealer network. While they may not always stock older parts, they can often order them directly from the manufacturer or provide useful information on where to locate them.
  • Tip: If your local dealer doesn't have the part you need, consider reaching out to global Mitsubishi dealers. Some international dealers may have leftover stock or access to parts that are no longer available locally.
2. Online Marketplaces and Auctions
Many online platforms like eBay, Craigslist, and specialized heavy equipment auction sites have listings for parts and sometimes even entire machines. These platforms are often a goldmine for hard-to-find parts for older machinery.
  • Tip: Be cautious when purchasing parts online. Always verify the part’s compatibility with your model and check the seller’s reputation before committing to a purchase.
3. Aftermarket Parts Suppliers
For many older models, aftermarket parts suppliers have stepped in to fill the gap left by manufacturers. These companies specialize in providing compatible parts for machines that are no longer supported by the original manufacturers.
  • Example: Companies like Hemmings Machinery, Vickers, and A&I Products provide aftermarket parts that often match the performance of the original components. Many of these suppliers offer parts for a wide range of equipment, including older models like the Mitsubishi MS180LC.
4. Salvage Yards and Equipment Breakers
Salvage yards and equipment breakers are often overlooked but can be incredibly valuable sources of parts for older machinery. Many of these yards buy used equipment and dismantle them for parts. If you are lucky, you may find a Mitsubishi MS180LC being broken down for parts.
  • Tip: If you find a similar model being scrapped, ask about its condition and the availability of parts. Sometimes, the best solution is a direct replacement from a salvaged machine that still has a few useful years left.
5. International Parts Suppliers
If local options are unavailable, expanding your search to international suppliers can be beneficial. Countries with a strong presence in the construction equipment market, such as Japan, China, and Europe, may have more readily available parts for the MS180LC.
  • Tip: Contacting suppliers in Japan, where Mitsubishi construction equipment is originally manufactured, may provide access to rare or discontinued parts.
Common Parts to Check for Availability
Some of the most common parts that often require replacement on older machines like the MS180LC include:
  • Hydraulic Pumps and Motors: The hydraulic system is essential for operating the arms and bucket of an excavator. Over time, these components wear out, and finding replacements can be challenging.
  • Undercarriage Components: Tracks, sprockets, idlers, and rollers are subject to wear and tear, especially on older machines that have seen heavy use.
  • Engine Parts: Diesel engines, particularly older ones, often need parts like injectors, alternators, filters, and seals replaced over time.
  • Cab and Control Components: Parts inside the cab, such as controls, switches, and wiring, may degrade due to age and exposure to the elements.
  • Electrical Systems: With the advent of modern electrical systems, components like batteries, alternators, and starters for older machines can be difficult to source.
  • Cooling System Parts: Radiators, thermostats, and water pumps are subject to wear and corrosion, especially in regions with harsh operating environments.
The Importance of Regular Maintenance
Keeping an older machine like the Mitsubishi MS180LC in good condition requires regular maintenance and timely replacement of worn-out parts. Developing a proactive maintenance schedule can extend the life of the machine, reduce costly repairs, and improve its overall performance.
  • Engine Maintenance: Regularly changing the oil, air filters, and fuel filters can keep the engine running smoothly and help avoid performance issues.
  • Hydraulic System Care: Inspect hydraulic hoses for leaks, check fluid levels regularly, and replace seals to avoid expensive hydraulic repairs.
  • Track Maintenance: Keep track tension at optimal levels and replace undercarriage components before they wear down completely to prevent major damage.
  • Electrical System Checks: Routinely inspect and clean electrical connections, test batteries, and replace any corroded terminals to prevent electrical failures.
Conclusion: Strategies for Keeping Your Mitsubishi MS180LC Running
Finding parts for older machines like the Mitsubishi MS180LC can be a challenging but manageable task with the right approach. By utilizing a combination of Mitsubishi dealers, aftermarket suppliers, online marketplaces, and salvage yards, you can often source the necessary parts to keep your machine running.
In the long run, investing time and effort into regular maintenance will ensure that your MS180LC remains a valuable asset. With proper care and the right parts, this 1989 model can continue serving on the job site for many more years, helping operators maximize productivity and minimize downtime.
