Excavators are the backbone of the earthmoving and construction industry, tackling everything from heavy lifting to deep digging. When they break down, operations come to a screeching halt, leading to costly downtime and lost productivity. The good news? With proper preventative maintenance, early detection of wear, and strategic use of high-quality refurbished OEM parts, you can extend the life of your excavator and keep it running efficiently.
At Vikfin, we understand the frustrations of machine failures, and we’ve built our reputation on supplying top-quality used OEM parts that offer reliability at a fraction of the cost of new components. In this guide, we’ll cover seven essential ways to avoid common excavator breakdowns, helping you save time and money while keeping your machine in peak condition.
1. Keep Your Excavator’s Hydraulic System in Check
The hydraulic system is the lifeblood of an excavator, powering everything from the boom and arm to the bucket and slew function. Any failure in this system can bring operations to a halt.
Preventative Maintenance Tips:
✅ Check Hydraulic Fluid Levels Regularly – Running low on hydraulic fluid can lead to cavitation, overheating, and premature wear on components.✅ Look for Leaks – Small leaks can quickly become catastrophic failures. Check hoses, cylinders, and connections for signs of oil seepage.✅ Monitor System Pressure – If pressure fluctuates or drops, it could indicate a failing pump, clogged filter, or internal leakage.✅ Replace Hydraulic Filters on Schedule – Dirty filters can lead to contamination, damaging pumps, valves, and cylinders.
Vikfin Solution:
When hydraulic components wear out, replacing them with genuine OEM refurbished parts from Vikfin is a cost-effective way to restore full hydraulic function without breaking the bank. We stock a wide range of hydraulic pumps, cylinders, and valve banks, all tested to ensure peak performance.
2. Keep the Undercarriage Clean and Well-Maintained
Your excavator’s undercarriage takes a beating every day, especially in tough conditions like mining, demolition, and forestry work. Neglecting undercarriage maintenance can lead to premature failure of key components.
Preventative Maintenance Tips:
✅ Inspect Tracks Daily – Look for worn track links, loose bolts, and damaged rollers.✅ Keep It Clean – Excessive mud and debris accelerate wear and tear. Clean the undercarriage after each shift.✅ Adjust Track Tension – Too tight, and you wear out the tracks prematurely. Too loose, and they could derail.
Vikfin Solution:
We stock high-quality used track rollers, idlers, and steel tracks that can keep your excavator moving efficiently without the high cost of new replacements.
3. Pay Attention to Your Excavator’s Engine
An excavator’s diesel engine is its powerhouse. Neglecting engine maintenance can lead to catastrophic failures that are both costly and time-consuming to fix.
Preventative Maintenance Tips:
✅ Check Engine Oil and Filters Regularly – Old oil and clogged filters lead to overheating and engine damage.✅ Inspect Cooling System – Overheating can warp engine components, so check radiators, coolant levels, and water pumps.✅ Listen for Unusual Noises – Knocking, excessive vibrations, or rough idling could indicate internal engine problems.
Vikfin Solution:
Rather than investing in a brand-new engine, Vikfin offers fully refurbished OEM excavator engines, rigorously tested to meet manufacturer specifications. Whether you need a Volvo D6E, a Komatsu SAA6D107E, or a CAT C7, we have reliable options that fit your budget.
4. Don’t Ignore the Final Drive and Swing Motor
The final drive powers the tracks, while the swing motor enables cab rotation. Damage to either component can cripple your machine.
Preventative Maintenance Tips:
✅ Check for Leaks and Metal Shavings in Oil – These are early signs of gear wear or seal failure in the final drive.✅ Listen for Grinding Noises – A failing swing motor often makes a whining or grinding sound.✅ Keep Gear Oil Fresh – Old, contaminated oil reduces lubrication and leads to premature failure.
Vikfin Solution:
We stock high-quality used final drives and slew motors that can get your machine moving again at a fraction of the price of new components. Each unit is inspected for reliability, ensuring maximum durability and performance.
5. Watch for Electrical Issues and Wiring Problems
Modern excavators rely on complex electrical systems, and faulty wiring can cause unexpected failures.
Preventative Maintenance Tips:
✅ Check Battery Health – A weak battery can cause erratic performance or complete failure.✅ Inspect Wiring Harnesses for Damage – Loose or frayed wires can lead to faulty signals and machine shutdowns.✅ Test Sensors and Relays – Malfunctioning sensors can cause operational inefficiencies or false error codes.
Vikfin Solution:
We supply OEM wiring harnesses and electrical components, ensuring that your excavator’s electrical system runs smoothly without the risks associated with cheap aftermarket parts.
6. Protect Your Excavator’s Cooling System
Overheating is one of the most common causes of engine damage and hydraulic failure. Keeping your cooling system in check is essential.
Preventative Maintenance Tips:
✅ Flush the Radiator and Cooling Lines – Debris buildup can restrict coolant flow, leading to overheating.✅ Monitor Coolant Levels – Low coolant can cause major damage to engine components.✅ Check Fan Belts and Hoses – Cracked belts and leaking hoses are warning signs of impending failure.
Vikfin Solution:
Rather than replacing your entire engine due to overheating, consider our refurbished OEM cooling components, including radiators, oil coolers, and water pumps.
7. Avoid Boom, Stick, and Bucket Failures
Excavator arms take immense stress every day. Cracks, worn pins, and faulty cylinders can lead to unexpected failures that delay projects.
Preventative Maintenance Tips:
✅ Grease Pins and Bushings Daily – Lack of lubrication leads to excessive wear and joint failure.✅ Inspect Welds for Cracks – Tiny cracks can grow into major structural failures.✅ Watch for Cylinder Leaks – Oil leaks around the boom, dipper arm, or bucket cylinder indicate seal failure.
Vikfin Solution:
We stock refurbished OEM hydraulic cylinders, pins, and bushings, ensuring that your boom and stick remain in peak operating condition without the high cost of new parts.
