Excavators are the backbone of many construction projects, handling digging, lifting, and material movement with ease. However, like any heavy machinery, they require regular maintenance to stay in top working condition. Worn-out parts can lead to reduced efficiency, increased downtime, and costly repairs.
At Advantage Construction Equipment and Parts, we specialize in high-quality aftermarket, used, and rebuilt Volvo excavator parts, ensuring your machine operates at peak performance. In this guide, we’ll cover key signs of wear and tear, essential excavator components, and where to find reliable replacement parts to keep your Volvo equipment running smoothly.
Common Signs Your Excavator Parts Are Worn Out
Regular inspections are essential to keeping your excavator in peak condition. Catching early warning signs of wear and tear can prevent costly repairs and unexpected downtime. Here are the most common indicators that your excavator parts need attention, along with what you can do to fix them:
1. Decreased Performance
If your excavator is struggling to lift, dig, or move materials efficiently, it could indicate worn-out hydraulic components, cylinders, or tracks. You might notice sluggish movement, reduced digging force, or difficulty maneuvering the machine.
What to Do:
- Check hydraulic fluid levels and replace contaminated or low-quality fluid.
- Inspect the hydraulic pump and cylinders for leaks or signs of wear.
- Examine tracks for excessive wear and replace them if they have lost traction.
2. Unusual Noises
Grinding, squeaking, or knocking sounds coming from your excavator can be a red flag. These noises often point to issues with bearings, hydraulic pumps, or final drives. Ignoring these sounds can lead to severe damage and higher repair costs.
What to Do:
- Grease moving parts regularly to prevent metal-on-metal wear.
- Inspect final drive motors and bearings for looseness or damage.
- Replace faulty hydraulic pumps if they show signs of excessive wear or noise.
3. Leaking Fluids
If you notice hydraulic fluid, engine oil, or coolant pooling beneath your excavator, you could be dealing with damaged seals, cracked hoses, or failing hydraulic components. Fluid leaks can quickly lead to low system pressure, reducing performance and increasing the risk of major failures.
What to Do:
- Check hoses and fittings for cracks or loose connections.
- Replace worn-out seals or gaskets in hydraulic cylinders and pumps.
- Keep an eye on fluid levels and top them off as needed to prevent system damage.
4. Uneven Track Wear
Tracks that wear down more on one side can indicate alignment issues, improper tension, or worn-out undercarriage components. Uneven wear puts extra strain on your excavator’s drivetrain, reducing efficiency and increasing operating costs.
What to Do:
- Inspect rollers, idlers, and sprockets for misalignment or excessive wear.
- Adjust track tension to manufacturer specifications to prevent premature failure.
- Rotate or replace worn tracks to maintain even wear and optimal traction.
5. Slow Hydraulic Response
A lag in boom, arm, or bucket movement can make your excavator less efficient and harder to operate. This issue is often caused by clogged hydraulic filters, failing pumps, or low-quality hydraulic fluid.
What to Do:
- Replace hydraulic filters regularly to prevent clogs and contamination.
- Monitor pump performance and replace worn-out components as needed.
Essential Excavator Parts and Their Functions
Understanding your excavator’s components can help you diagnose issues quickly and maintain efficiency. Here’s a breakdown of the most critical parts:
1. Undercarriage
The undercarriage is the foundation of an excavator, responsible for stability and movement. It includes:
- Tracks: Provide traction and mobility over rough terrain.
- Rollers & Idlers: Help distribute weight evenly and keep tracks aligned.
- Sprockets: Engage the track links, driving the machine forward.
When tracks or rollers wear out, movement becomes uneven, increasing the risk of damage to other components.
2. Hydraulic System
Hydraulic power is what enables excavators to perform heavy-duty tasks. Key components include:
- Hydraulic Cylinders: Control the boom, arm, and bucket movement.
- Pumps & Valves: Regulate hydraulic pressure for smooth operation.
- Hoses & Seals: Ensure efficient fluid flow and prevent leaks.
Low hydraulic pressure or sluggish movement often indicates worn-out seals, clogged filters, or failing pumps.
3. Boom, Arm, and Bucket
These components are essential for digging, lifting, and earthmoving.
- Boom: Provides vertical reach.
- Arm (Dipper): Extends the boom’s reach and supports the bucket.
- Bucket: Comes in different sizes and styles for various excavation tasks.
Cracks, dents, or slow movement in these parts can signal structural wear or hydraulic system issues.
4. Final Drives
Final drives are crucial for propelling your excavator and ensuring smooth track movement. At Advantage Construction Equipment and Parts, we specialize in high-quality aftermarket and rebuilt Volvo final drives and swing drives, offering a 2-year warranty for added peace of mind. If you notice power loss, excessive noise, or leaks, it’s time to check your final drive for issues.
Maintaining Your Excavator to Prevent Part Failures
Routine maintenance can extend the lifespan of your excavator and prevent unexpected breakdowns. Here are three key maintenance steps:
1. Regular Inspections
- Check fluid levels, hoses, and seals for leaks.
- Inspect undercarriage components for signs of excessive wear.
- Monitor final drive oil levels to prevent overheating and failure.
2. Lubrication & Cleaning
- Grease pins, bushings, and bearings regularly to reduce friction.
- Keep tracks and rollers clean to prevent dirt buildup that accelerates wear.
3. Replacing Worn-Out Parts
- Don’t wait for failure—replace components like filters, seals, and hoses as part of routine maintenance.
- Use high-quality aftermarket and rebuilt parts from Advantage Construction Equipment and Parts for reliable performance and longevity.
