How to Identify Komatsu Travel Motor Failure Signs

Introduction

There are some sgins such as the track unmovement, reduced the power or complete breakdown when the travel motor has problems.

Knowing these signs can help you reduce downtime and prevent your machine further damage.

What is a Travel Motor?

The travel motor offer the powers the excavator tracks, it is a part of the final drive system. A good travel motor makes excavator move smoothy and handle heavy-duty operations.The motor drive converts hydraulic energy into torque to driving the excavator forward or backward

Common Failure Signs in Komatsu Travel Motors

Unusual Noises

If you heard grinding, knocking noises it means worn gears or internal damage.

Loss of Power

If your Komatsu excavator is hard to climbing slopes or moves slowly than usual, the travel motor may have lost hydraulic efficiency.

Oil Leaks

If there are visible oil leaks around the Komatsu travel motor housing it maybe the seal failure, which can quickly lead to overheating and internal wear.

Uneven Track Movement

If the excavator has one side runs faster than the other side, it means the aother side motor is failling weak

Excessive Heat

If the internal friction overheating in the travel motor it means lack of lubrication.

Metal Shavings in Oil

If the gears or bearing are break or wearing out the metal will shows from the motor.

Affected Komatsu Models

These signs are very common across Komatsu excavators, including blow models:

PC200-7 – often shows power loss and oil leakage when travel motor is worn.

PC128UU-1 – compact model prone to uneven track movement.

PC400 – heavy-duty model where grinding noises indicate gear wear.

How to Prevent Travel Motor Failure

Regular check the oil for contamination or low levels.

Follow the maintenance scheduled time to replace seals and bearings before total failure.

Use original or trusted aftermarket motors to ensure the quality.

When to Replace vs Repair?

If the minor parts fail or the seals leak oil we suggest you replace the seal the gear, the bearings or the motor core if it is necessary.

👉 In most cases, a new final drive is more cost-effective than repairs.

By knowing early warning signs such as oil leaks, uneven movement, power loss, you can take advanced action and avoid costly downtime.

Komatsu excavator’s performance depends on the travel motor.
