Common Issues with the Mitsubishi BD2G and How to Address Them
While the Mitsubishi BD2G is known for its robustness, like any piece of heavy machinery, it may encounter issues over time. Here are some common problems and their potential solutions:
1. Engine Starting Issues
One of the most common problems with older dozers like the BD2G involves engine starting issues. This could be caused by a range of factors, from fuel delivery problems to electrical issues.
Possible Causes and Solutions:
- Fuel System Blockages: Ensure the fuel lines are clear and not clogged. Old or contaminated fuel can also affect the engine’s performance. Replace the fuel filter regularly and use fresh fuel.
- Glow Plug Problems: In cold weather, glow plugs are crucial for starting the engine. If the glow plugs are faulty, the engine may struggle to start. Check for resistance across each glow plug and replace any defective ones.
- Battery or Starter Motor Issues: If the engine turns over slowly or doesn’t start at all, check the battery voltage. A weak battery or faulty starter motor could be the cause. Replace the battery if necessary, or inspect the starter for worn-out components.
The BD2G’s 2-speed mechanical transmission and hydraulic system are crucial for its performance. Problems in these areas can significantly impact the machine’s ability to operate smoothly.
Possible Causes and Solutions:
- Transmission Slipping or Sticking: This could result from low fluid levels or contamination. Check the fluid levels and condition, and replace the hydraulic or transmission oil if it appears dirty or low.
- Hydraulic Pump Failures: If the hydraulic system is sluggish or unresponsive, check the hydraulic pump. Worn seals, valves, or internal components may need to be replaced.
The track system on the BD2G is essential for its mobility and stability. Over time, tracks can wear down or lose tension, leading to inefficient operation.
Possible Causes and Solutions:
- Track Tension: The tracks should be regularly checked for proper tension. Over-tightening can cause undue strain on the undercarriage, while loose tracks can result in poor traction. Use the tension adjustment bolts to ensure the correct tension is maintained.
- Track Pads and Link Wear: Inspect the track pads for wear, cracks, or breakage. Worn pads can reduce traction and make the dozer less effective. Replace damaged or excessively worn track pads to ensure optimal performance.
The blade is a crucial component of the BD2G, and problems here can affect the machine's ability to grade, level, or push material.
Possible Causes and Solutions:
- Hydraulic Cylinder Leaks: If the blade is not responding correctly, inspect the hydraulic cylinders for leaks. Replacing seals or worn cylinders may be necessary to restore full functionality.
- Blade Alignment: Over time, the blade may shift or become misaligned, especially if the dozer has been used in rough conditions. Ensure that the blade is aligned properly and check the mounting points for any signs of wear or loosening.
Regular maintenance is key to keeping the Mitsubishi BD2G running efficiently and extending its operational life. Here are some essential maintenance tasks to perform on the BD2G:
- Engine Oil Change: Change the engine oil every 200 to 250 operating hours, depending on usage. Use the manufacturer-recommended oil grade to ensure proper lubrication and engine longevity.
- Fuel and Air Filters: Replace fuel and air filters regularly—typically every 250 to 500 hours. Dirty filters can restrict airflow and fuel flow, reducing engine efficiency.
- Track Maintenance: Inspect the tracks every 100 hours for wear, tension, and damage. Keep the track system lubricated and make adjustments as needed to avoid excessive wear.
- Hydraulic Fluid Levels: Check hydraulic fluid levels regularly, especially if the dozer is being used heavily. Top off fluid as needed and replace the hydraulic fluid every 1,000 hours or as specified in the service manual.
- Cooling System Maintenance: Regularly check the coolant levels and inspect the radiator for any signs of leaks or blockages. A well-maintained cooling system helps prevent overheating and keeps the engine running smoothly.
To get the most out of your Mitsubishi BD2G and avoid costly repairs, consider the following:
- Operate within Recommended Limits: The BD2G is designed to handle specific tasks. Avoid overloading the machine or pushing it beyond its design limits to prevent undue strain on the engine and transmission.
- Use Quality Fuel and Fluids: Using high-quality fuel and lubricants is crucial for the longevity of the BD2G. Avoid using low-grade fuel that may cause clogging in the fuel system, and opt for the recommended oils and hydraulic fluids.
- Store Properly: If the dozer is not in use for an extended period, store it in a dry, clean environment. This prevents rusting and corrosion of the metal components, especially in the undercarriage and blade.
- Regular Inspections: Conduct routine inspections of all systems—engine, hydraulic, and tracks—to detect any signs of wear or damage early. Early intervention can save significant repair costs later on.
