Description

Komatsu PC240LC Final Drive (Travel Motor) – 206-27-00422

The Komatsu PC240LC Final Drive is the undercarriage drive assembly that transfers hydraulic power into the torque needed to move the excavator tracks. Operators and mechanics may also search for this part as a Komatsu travel motor, Komatsu track drive, Komatsu drive motor or Komatsu final drive assembly when looking for a complete replacement unit.

Built as a 24–26 tonne-class crawler excavator, the Komatsu PC240LC is widely used in earthmoving, civil construction, excavation, roadworks, quarry support and infrastructure projects. When the final drive starts to wear, the excavator can lose travel strength, track unevenly or struggle under load.

Warning signs your Komatsu PC240LC final drive may be wearing out

The PC240LC often works in rough ground, clay, mud, slopes, quarry access tracks and long travel paths across civil or excavation sites. These conditions can place a heavy load on the final drive, travel motor and related Komatsu undercarriage parts. Common warning signs include:

• Whining, grinding or clicking from the sprocket or travel motor area
• Gear oil leaking around the hub seal, final drive cover or housing
• One track moving slower than the opposite side during travel
• The machine drifting to one side when tracking in a straight line
• Weak travel force when climbing, turning or pushing through soft ground
• Heat building up in one final drive housing after the operation
• Metal contamination in the gear oil during service checks
• Intermittent or complete loss of drive on one side of the excavator

Replacing a failing final drive early can help reduce the risk of further damage to the planetary gears, bearings, sprocket, track chain and hydraulic travel circuit.

New aftermarket or rebuilt — which replacement option should you use?

• New aftermarket Komatsu final drive assembly: It is a strong option when you need reliable travel performance, warranty support and a cost-effective alternative to genuine OEM pricing. It suits contractors, plant hire companies, repair workshops and equipment owners who need the PC240LC back on site quickly.
• Fully rebuilt Komatsu travel motor or final drive: It may be suitable when available and when repair cost control is important. Rebuilt units are inspected, prepared and tested before supply, making them a practical option for high-hour machines and urgent replacement jobs.

Tell Arena how your PC240LC is being used — civil construction, quarrying, trenching, roadworks, bulk earthmoving or general excavation — and we can help recommend the most suitable replacement option.
