Used Komatsu Excavator Buyer Guide: Problems & Costs
Hydraulic System Issues
Hydraulic system problems happen a lot with used Komatsu PC200 excavators. You might see the machine move slowly or jerk. Sometimes, it cannot lift heavy things well. You may also spot leaks under the machine. These problems often come from worn seals or broken hoses. The main pump can also have issues. If the pilot control valve stops working, the pump swashplate might not open. This makes the pump flow less and the machine moves slowly. Leaks in the small arm cylinder or a broken hydraulic seal can make the machine work worse and leave oil spots.
Hydraulic repairs usually cost between $1,000 and $3,000. The price depends on which part is broken and how much labor is needed. Older machines or ones not cared for may cost more to fix. These hydraulic problems can make the Komatsu PC200 used price go down. Buyers worry about more repairs in the future.
Tip: Listen for strange pump sounds. Weird noises can mean bigger hydraulic problems that cost more to fix.
Engine and Cooling Problems
Engine and cooling system problems can stop the machine from working. You might see warning lights or the machine may get too hot. Sometimes, you hear strange engine noises. Common engine and cooling problems are:
1.Leaks in the cooling system or not enough coolant
2.Broken water temperature gauges
3.Scale buildup in the cooling system, which makes it hard to cool down、
4.Clogged radiator shrouds or radiator core ducts
5.Loose or broken water pump or fan belts
6.Damaged water pump, bent fan blades, or broken air rings
7.Thermostat stuck closed
8.Machine working too hard or fuel coming late
If you need a new radiator, it can cost $4,624 to $5,874 for a Komatsu PC200-6 radiator or feedlot radiator. Labor and other parts can make it cost even more. These repairs add up fast, so always check the engine and cooling system before buying. High repair costs can make the Komatsu PC200 used price lower, especially if the engine looks like it was not cared for.
Electrical and Battery Faults
Electrical and battery problems can keep your excavator from starting or running right. The starter motor might not work. The machine could lose power while working. The most common electrical problems are blown fuses, low battery voltage, bad relays, poor wiring connections, and starter motor failure.
Here is a simple checklist to find electrical problems:
| Step | Action | Description |
| 1 | Check fuse | Look to see if the fuse is blown. This can stop the starter motor. |
| 2 | Check battery voltage | Make sure the battery is above 24V and has enough liquid. |
| 3 | Check battery relay | Listen for a click when you turn the start switch. |
| 4 | Check wiring harness | Look at all connections for problems. |
| 5 | Check starter motor | If voltage is good but the motor does not work, replace the starter motor. |
Fixing electrical problems can cost $200 for a new fuse or relay. It can be $1,000 or more for a new starter motor. Bad electrical parts can make the Komatsu PC200 used price go down. Buyers want machines that work well.
Undercarriage and Track Wear
The undercarriage gets used a lot, so check for wear before buying. Signs of undercarriage and track wear are uneven track chains, bent shoes, flat spots on rollers, oil leaks, cracked idlers, and sharp sprocket teeth. Tracks that sag or are too tight can make other parts wear out faster.
| Component | Signs of Wear |
| Track Chains | Uneven wear, bent shoes |
| Rollers | Flat spots, oil leaks, worn flanges |
| Idlers | Cracks, too much tread wear, loose fit |
| Sprockets | Sharp or hooked teeth |
| Track Tension | Tracks that sag or are too tight |
| Misalignment | Uneven wear on one side |
| Overloading | Deep marks on chains, too much shoe wear |
Changing undercarriage parts can cost $3,000 to $8,000. Machines with new undercarriage parts can sell for a higher Komatsu PC200 used price. Worn tracks can make the price lower.
Automatic Extinguishing & Pump Sounds
Problems with the automatic extinguishing system and strange pump sounds can mean bigger issues. The machine might shut off by itself. You may hear odd noises from the hydraulic pump. These problems often come from:
1.Pilot control valve failures, which stop the pump from working right
2.Broken hydraulic seals, which cause leaks
3.Leaks in the small arm cylinder
4.Low pressure in the main pump from worn parts
5.Bad main pump control valves, which cause flow problems
6.Poor quality oil, which lowers output pressure
7.Blocked main relief valve, which lowers system pressure
You may pay $1,500 to $4,000 for these repairs. The price depends on what is broken. These problems can scare buyers and make the Komatsu PC200 used price lower, especially if the machine has had pump or extinguishing system problems before.
Komatsu PC200 Used Price Factors
Many things change the Komatsu PC200 used price. You should think about:
1.Model generation. Newer models have better hydraulics and electronics, so they cost more.
2.Operating hours. Fewer hours usually mean a higher price. Good maintenance helps older machines keep value.
3.Condition and rebuilds. Machines with new undercarriage, engine, or hydraulic work are worth more.
4.Attachments. Extra buckets, quick couplers, or hammers can make the price go up.
5.Origin and paperwork. Clear documents and original serial numbers add value.
6.Logistics. Shipping and transport costs can change the price, especially for buyers in other countries.
A good maintenance history also makes the Komatsu PC200 used price higher. If repairs are needed or service records are missing, the price can go down. Buyers worry about paying for repairs later.
Typical Repair Cost Breakdown
You should plan for repairs when buying a used Komatsu PC200. Here is a normal breakdown:
1.Hydraulic system repairs: $1,000–$3,000
2.Engine and cooling repairs: $2,000–$6,000
3.Electrical and battery repairs: $200–$1,000
4.Undercarriage and track repairs: $3,000–$8,000
5.Automatic extinguishing and pump repairs: $1,500–$4,000
Note: Machines with good maintenance and new repairs often sell for a higher Komatsu PC200 used price. You can avoid surprises by checking service records and looking at all main systems before you buy.
Knowing about these common problems and repair costs helps you make a smart choice. You can avoid paying too much and pick a machine that fits your needs and budget.
