Preventing Premature Wear in Excavator Undercarriages: The Role of OEM Track Components

The undercarriage is the foundation of your excavator. It carries the entire weight of the machine, transfers engine power to the ground, and endures some of the harshest working conditions in construction and mining. Despite this, it’s also one of the most neglected areas when it comes to maintenance.

Premature wear of the undercarriage is a silent profit killer. It leads to costly downtime, expensive repairs, and shortened machine life. The good news? With proper maintenance and by using OEM (Original Equipment Manufacturer) track components, you can dramatically extend undercarriage life and save thousands in operating costs.

At Vikfin, we specialize in used OEM excavator parts, including track chains, rollers, idlers, sprockets, and track shoes for leading brands like CAT, Komatsu, Hitachi, Volvo, and Doosan. In this blog, we’ll explore:

• Why undercarriage wear happens faster than you think

• How OEM track components make a difference

• Best practices to extend undercarriage life

• How Vikfin helps contractors and operators maximize ROI

1. Why the Undercarriage Matters More Than You Realize

For tracked excavators, the undercarriage can represent up to 50% of the total maintenance costs over the machine’s lifetime. This includes:

• Track Chains and Links: Responsible for transmitting motion and supporting the machine’s weight.

• Sprockets: Engage the track links to drive the machine forward.

• Rollers and Idlers: Maintain proper track tension and alignment.

• Track Shoes: Provide traction on various terrains.

When these components wear prematurely, you’re not just replacing parts—you’re losing productivity and risking catastrophic failures.

2. The Hidden Causes of Premature Undercarriage Wear

Most undercarriage failures are not due to age but avoidable issues, such as:

• Improper Track Tension: Too tight accelerates wear; too loose causes de-tracking.

• Poor Operating Habits: Excessive high-speed travel, sharp turns, and constant reverse movement.

• Unbalanced Work Sites: Operating frequently on slopes or rocky terrain increases stress.

• Contaminants: Mud, sand, and debris act as abrasives, grinding down components.

• Inferior Replacement Parts: Cheap aftermarket parts often don’t meet OEM material standards, leading to faster wear.

Understanding these factors is key to stopping premature wear before it starts.

3. Why OEM Track Components Are Worth the Investment

When replacing worn undercarriage parts, you might be tempted to save money with aftermarket alternatives. Here’s why OEM parts are the smarter choice:

Precision Engineering

OEM parts are manufactured to exact specifications set by the original machine builder. This ensures a perfect fit, optimal performance, and reduced stress on surrounding components.

Superior Materials

OEM track components are made from high-grade steel alloys designed to withstand extreme loads, impacts, and abrasives. Aftermarket parts often compromise on material quality.

Longer Service Life

Thanks to better metallurgy and heat treatment processes, OEM parts last significantly longer, reducing total ownership costs.

Maintains Machine Value

Using genuine OEM parts preserves the resale value of your excavator. Prospective buyers trust machines with documented OEM maintenance.

Warranty & Support

Most OEM parts come with warranties, giving you added peace of mind.

4. Best Practices to Extend Undercarriage Life

Pairing OEM parts with good maintenance habits is the winning formula:

1. Maintain Proper Track Tension

Check track tension daily. Refer to your machine’s manual for correct specifications. Over-tight tracks increase stress on pins, bushings, and sprockets; loose tracks risk derailment.

2. Clean the Undercarriage Daily

Mud, clay, and debris act like sandpaper. Cleaning after every shift prevents accelerated wear.

3. Inspect Regularly

Look for abnormal wear patterns, cracks, or loose components. Early detection saves money.

4. Rotate Track Chains

Flipping or rotating pins and bushings at the right intervals can double chain life.

5. Train Operators

Skilled operators who avoid unnecessary spinning, sharp turns, and excessive high-speed travel significantly reduce wear.

6. Match Track Shoes to Terrain

Using the correct shoe width for the ground conditions prevents uneven wear and improves traction.

5. When to Replace vs. Repair

Knowing when to replace components is vital:

• Replace Entire Chains: When pins and bushings are worn beyond tolerance.

• Replace Sprockets: Whenever you install new chains; worn sprockets quickly damage new links.

• Replace Rollers & Idlers: If seals fail or excessive play develops.

Replacing components in sets ensures even wear and better long-term reliability.

6. The Vikfin Advantage: Quality OEM Track Components

At Vikfin, we help you get the most from your excavators by providing:

• Genuine OEM Parts: Track chains, rollers, sprockets, and idlers sourced from trusted suppliers.

• Used but Certified Quality: All parts are inspected and tested to meet OEM standards.

• Cost Savings: Significant discounts over new parts without sacrificing quality.

• Expert Advice: Our team helps you select the right components and implement proper maintenance strategies.

• Fast Delivery: We keep stock on hand in Durban and Johannesburg, ensuring minimal downtime.

7. Real-World Cost Savings

Consider this example:

• Cheap aftermarket parts last 1,200 hours before failure.

• OEM parts last 2,500+ hours with proper care.

Even if OEM parts cost 30% more upfront, you save significantly in reduced downtime, fewer replacements, and extended machine life.

8. How to Get Started

If you’re serious about cutting costs and improving reliability:

1. Inspect your current undercarriage.

2. Switch to OEM components for replacements.

3. Partner with a supplier like Vikfin for ongoing support.

Conclusion

Your excavator’s undercarriage is too important—and too expensive—to ignore. Premature wear drains profits, disrupts schedules, and shortens machine life. The solution is straightforward: combine proactive maintenance with high-quality OEM track components.

At Vikfin, we’re committed to helping you protect your investment. Our inventory of used, inspected OEM parts delivers durability, reliability, and value—so your machines keep working as hard as you do.
