Replacing a loader undercarriage isn’t cheap—but it’s essential. If your machine tracks unevenly, vibrates, or loses traction, the undercarriage is likely the culprit. This system takes the most abuse, especially in dirt, mud, and rocky conditions. Ignoring wear can lead to machine downtime, lost revenue, and expensive structural damage.
The cost to replace a loader undercarriage depends on several factors. Machine size is the biggest one. A small track loader undercarriage might cost $3,000 to $6,000 in parts. A mid-sized loader? $8,000 to $12,000. For large models in mining or quarrying applications, the cost can exceed $20,000. That’s just for parts—labor adds more.
Component quality matters too. Some contractors try to save with cheap aftermarket parts. But low-grade steel and poor welds won’t last. You end up paying twice. High-quality undercarriage parts—rollers, idlers, track chains, sprockets—extend machine life and reduce long-term cost.
Operating conditions also play a role. Harsh terrain wears out parts faster. Running on abrasive surfaces like gravel or sand accelerates wear on rollers and chains. Poor track tension causes premature failure. That’s why investing in durable, OEM-level parts is smarter.
At LoaderTrackParts, we supply full undercarriage systems designed to match OEM specs for loaders of all sizes. We cover brands like Caterpillar, Bobcat, CASE, Komatsu, and more. Our parts are engineered for strength, wear resistance, and fit accuracy. We also support fleet operators and rental companies with volume pricing.
We offer guidance on how to evaluate wear before full replacement. Our team helps calculate cost-per-hour for parts based on your machine usage. Customers get more than just parts—they get expert support, fast shipping, and confidence in every component.
Undercarriage replacement is a major investment, but avoiding it leads to bigger problems—like seized sprockets, cracked frames, or damaged drive motors. Replacing worn parts before total failure saves money, reduces downtime, and protects your loader’s resale value.
