Komatsu/Demag hydraulic excavator parts designed for heavy applications

You depend on your Komatsu®/Demag® equipment, and when vital components fail, getting your machinery up and running again is a top priority. But that’s only the beginning. Invest in spare part solutions that do more than just repair; optimise your Komatsu/Demag Hydraulic Excavators, with high-value, high performance parts from EXCEL™.

Looking to improve performance?


Our designs will improve your operation through increased performance and/or ease of use (compared to typical Komatsu/Demag parts). Make a small investment for a quick return with a wide variety of improved designs customised for Komatsu/Demag excavators. Below are more details on these components – many of which are not available from your typical undercarriage parts supplier.



Innovation by design


You need a replacement part that is more efficient and performs better than the original, and we work to deliver. Our replacement parts are backed by our F3 Commitment to Fit, Form and Function. In many cases, our engineers have modified and improved the conventional Komatsu/Demag undercarriage components to greatly improve durability and performance. Our high performance parts deliver value and performance, from pin and bushing sets to complete undercarriage replacements.

EXCEL parts for Komatsu/Demag Hydraulic Excavator: the ideal fix

When you depend on your hydraulic excavators to power your business, something as small as a single failed component can bring everything grinding down to a halt. Our top-quality spare parts for Komatsu/Demag Hydraulic Excavators put your business back in operation, improving performance and decreasing maintenance times in the process.

Improved performance

These Komatsu/Demag spare parts are a smart investment for any mining site. Our durable, reliable designs allow for better equipment performance and throughput.

Innovative design

When a part fails, replacing it with the exact same part will most likely give you the exact same outcome. We’ve improved upon existing designs, so that you can expect a longer operational life from our spares. 

Reduced maintenance costs

Longer operational life means longer periods of operation between maintenance downtimes. That means better throughput, and increased revenue for your business. 

The right components for your hydraulic excavators

Invest in parts you can rely on. We offer spare parts for a wide range of Komatsu/Demag Hydraulic Excavator models, backed by our F3 Commitment to Fit, Form and Function. Our spare parts are made from the most durable materials and are specifically designed to improve excavator performance.

Komatsu/Demag excavator undercarriage parts


Standard offerings

  • Custom retention hardware to fully retain the pin head
  • Optimised internal cavity for thicker cross sections to reduce back-bending
  • Case hardening deeper than conventional wear limits
  • Forged one-piece rollers
  • Manganese track shoes for durability in hard rock applications
  • Fully-supported roll path


Overpitch drive tumbler

A properly timed replacement extends the life of the track shoes and reduces additional damage on replacement tumblers. Operations get more uptime and extended life from their track shoes. The resulting performance simulates ‘like-new’ pitch conditions. The overpitch drive tumbler installs as a direct replacement for the conventional drive tumbler.


Forged one-piece rollers

Rock solid performance

  • Retains grain integrity resulting in maximum grain strength.
  • Reduces and refines the coarse cast grain structure. Forging does NOT change the volume or density of the steel.
  • Uniform grain size and directional flow maximise strength.


Komatsu/Demag High Flotation Track Shoes


Improved weight distribution

The massive crushing weight of an excavator wreaks havoc on its undercarriage, which can be hard on your operation. By improving the traditional track shoe design, we offer an effective weight-distribution solution. The redesigned shoe improves material flow throughout its wear life and is proven to extend track shoe life.


Komatsu/Demag Overpitch Drive Sprocket


Compensates for typical elongation

Misalignments cause unnecessary drive sprocket wear, shortening component life and causing excess downtime. Our design addresses the misalignment between the track shoe drive lugs and the drive sprocket.


Allows additional 50% of usable track shoe lifespan

A properly timed replacement extends the life of the track shoes and reduces additional damage on replacement sprockets. Operations get more uptime and extended life from their track shoes. The resulting performance simulates ‘like-new’ pitch conditions. The overpitch drive sprocket installs as a direct replacement for the conventional drive sprocket.


The solution to mismatched engagement

Normal wear and tear reduce the pin size and enlarges the bores. Continual wear of these components increases the overall length of the track. Longer tracks cause drive lugs to be out of pitch with the drive sprocket. We focus our improvements on the primary cause of misalignment: excess space between the track shoes.
