What is an axle on a construction machine?

The axle is the transmission component that connects the gearbox to the wheels. It transmits driving power, supports the machine's weight, and maintains ground contact. On wheeled excavators and loaders, it also includes the differential, which allows wheels to rotate at different speeds when turning, and sometimes a locking system to improve traction on challenging terrain.

How can I tell if it’s the axle or axle nose that’s faulty?

If loss of traction or unusual noise comes from a specific wheel, it’s often the axle nose on that side causing the issue. If the problem affects both wheels on the same axle or the differential itself is noisy, it is more likely the entire axle that needs inspection. A technician’s diagnosis is necessary to determine this before ordering the part.

How do I identify the axle compatible with my machine?

Note your machine’s brand, model, and serial number, as well as the manufacturer’s reference stamped on the original axle if still legible. Our technical team will confirm compatibility before making a proposal.

Is a used axle reliable for construction equipment?

Yes, provided it has been inspected before sale. At Codimatra, each axle undergoes checks for seal tightness, bearing condition, and housing integrity before being put back into circulation. Parts with excessive wear are never sold.
