Condition of Used Excavator Parts
When you buy used excavator parts, you must check their condition before making a decision. Careful inspection helps you spot hidden problems and avoid costly repairs. You should always look for cracks, welds, wear, corrosion, and the state of bushings and pins. These checks keep your machine safe and reliable.
Cracks and Welds
Start your inspection by looking for cracks and welds on all used excavator parts. Cracks often appear in high-stress areas like the boom, arm, and bucket. Welded joints handle heavy loads and can develop fatigue cracks over time. If you see any cracks, you should not ignore them. Even small cracks can grow and cause sudden failure.
Welds also need close attention. Poor welds or old repair welds may not be as strong as the original metal. Studies show that weld repairs can have up to 50% less fatigue resistance than the base material. Weld defects like pores or lack of fusion weaken the part and make it unsafe. You should check for signs of patchwork or uneven weld beads. These can signal past repairs or hidden damage.
Tip: Use a flashlight and magnifying glass to check for tiny cracks or weld flaws. If you find any, ask a professional for a more detailed inspection.
Wear and Corrosion
Wear and corrosion are common in used excavator parts. You should check all moving parts, especially bucket teeth, cutting edges, and undercarriage components like track rollers, pins, and shoes. Look for thinning metal, sharp edges, or uneven surfaces. These signs show that the part has lost material and may fail soon.
Corrosion often appears as rust or pitting. It weakens the metal and can spread quickly. You should also check for signs of oil or coolant leaks, which can speed up corrosion. Wear debris analysis helps experts track how fast parts wear out. For example, rising levels of iron and chromium in engine oil show that wear is getting worse. The table below shows how these metal levels can increase over time:
Sample No. | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
Iron (ppm) | 5 | 5 | 9 | 10 |
Chromium (ppm) | 15 | 25 | 40 | 120 |
You can see that both iron and chromium levels rise as the part wears out. This means you should replace parts before wear becomes severe. Hydraulic oil analysis also helps you spot wear in hydraulic components. High iron or copper levels in the oil mean the parts are wearing out faster.
Note: Standard maintenance like oil changes does not always slow down wear. You must rely on regular inspection and monitoring to catch problems early.
Bushings and Pins
Bushings and pins connect many moving parts in your excavator. They are some of the first used excavator parts to wear out. You should check for excessive play, uneven wear, or missing grease. If you feel sloppy movement between pins and bushings, you need to replace them soon.
Worn bushings and pins can damage the frame and other parts. This leads to higher repair costs and more downtime. You should always replace both the pin and the bushing together. The bushing is designed to wear out first to protect the rest of the machine. If you ignore worn bushings, you risk damaging expensive components.
Here are some signs that bushings and pins need attention:
Excessive clearance or loose fit
Abnormal noise or vibration during operation
Grease leaking out or dry surfaces
Visible track pitching on the undercarriage
Modern bushings often have grease channels to keep them lubricated. Regular greasing and rotating the pins and bushings every 2,000 hours can extend their life. If you see any of these warning signs, you should act quickly to prevent further damage.
Aspect | Details |
|---|---|
Signs of Wear | Excessive clearance, abnormal noise, lubrication loss, vibration, misalignment |
Maintenance Tips | Keep parts lubricated, avoid overload, check alignment, inspect regularly |
Materials | Pins: hardened steel; Bushings: bronze, composites, PTFE |
You should always include bushings and pins in your inspection checklist for used excavator parts. This step helps you keep your machine reliable and safe.
Callout: Pins and bushings protect your machine from bigger failures. Regular inspection and timely replacement save you money in the long run.
By checking for cracks, welds, wear, corrosion, and bushing wear, you make sure the used excavator parts you buy will last and keep your equipment running smoothly.
Hydraulic and Engine Parts
Leaks and Seals
You should always check for leaks and seal problems before buying any hydraulic or engine part. Leaks can cause low pressure and poor performance. Start by looking for oil stains or wet spots around hoses, fittings, and seals. Use your hand to feel for slippery surfaces. If you see oil dripping or pooling, the seal may have failed.
A good seal keeps the hydraulic system strong. If you find cracked or worn seals, you should replace them. Pressure testing with gauges helps you spot leaks in rod and piston seals. If the pressure drops quickly, you may have a hidden leak. You can also use a handheld heat detector to find leaks. Leaks often make the area warmer because fluid escapes and creates heat.
Tip: Always check the maintenance history of the part. A part with regular service is less likely to have hidden leaks.
Hydraulic Cylinders
Hydraulic cylinders do the heavy lifting on your excavator. You need to inspect them closely. Look for scratches, dents, or rust on the cylinder rods. Check the cylinder walls for scoring or pitting. These signs mean the cylinder has seen a lot of use and may fail soon.
You can use a pressure gauge to test the cylinder. If the cylinder cannot hold pressure, the seals or internal parts may be worn out. Watch for erratic movement or slow operation. These symptoms often point to leaks or worn seals. A borescope helps you see inside the cylinder for hidden damage.
Check for:
Bent rods
Cracked or worn seals
Oil leaks at the ends
Rust or pitting on the surface
Regular inspection and preventive maintenance help you catch problems early. This keeps your excavator running longer.
Engine Wear
The engine is the heart of your Hitachi EX100. You should check for signs of wear and poor performance. Listen for knocking sounds or rough running. Look for smoke from the exhaust. These signs may mean the engine needs an overhaul.
Check the oil for metal shavings or a burnt smell. Dirty or low oil can damage engine parts. Inspect belts, hoses, and filters for cracks or wear. If you see oil leaks around the engine, fix them before they cause bigger problems.
A well-maintained engine lasts longer and saves you money. Always ask about the part’s service record. If the engine has a good maintenance history, you can trust it to work well.
Note: Careful checks of hydraulic and engine parts help you get the most life from your hitachi ex100 excavator parts.
