Komatsu PC300LC Final Drive (Travel Motor)

Description

Komatsu PC300LC Final Drive (Travel Motor)

The Komatsu PC300LC Final Drive is the track drive assembly that transfers hydraulic power through the travel motor and reduction gears to move the excavator under load. It is commonly searched as a Komatsu travel motor, Komatsu drive motor, Komatsu track drive or Komatsu final drive assembly when operators need a complete replacement for a heavy-duty crawler excavator.

The PC300LC is a 30-tonne-class excavator commonly used in civil construction, quarrying, bulk earthmoving, excavation, demolition support and infrastructure work. When the final drive starts to wear, the machine may lose travel power, track unevenly or stop moving on one side. Arena Hydraulic & Machinery supplies replacement Komatsu PC300LC final drives and supports customers looking for a reliable Australian final drive motor supplier with warranty-backed service and fast freight options.

At Arena, we supply high-quality replacement final drives for Komatsu PC300LC excavators. These units are selected for strong torque transfer, dependable travel performance and long service life in demanding Australian site conditions.

To help confirm the correct replacement before dispatch, send Arena your machine serial number, photos of the existing final drive and any stamped identification numbers on the unit. If you are checking options for Komatsu final drive parts or a complete excavator travel motor, you can also browse our wider range of excavator final drive assemblies for Komatsu and other excavator brands.

Every supplied final drive is backed by a 12-month warranty, with fast Australia-wide delivery available to help reduce downtime and keep your PC300LC working efficiently.

Warning signs your Komatsu PC300LC final drive may be failing

The PC300LC often works in heavy ground, quarry access tracks, civil sites, slopes, wet conditions and long travel paths. These conditions can place constant pressure on the final drive, travel motor and related Komatsu undercarriage parts. Common warning signs include:

• Whining, grinding or clicking from the sprocket, hub or travel motor area
• Gear oil leaking around the hub seal, housing or final drive cover
• 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 travelling 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 worn 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 is right?

• New aftermarket Komatsu final drive assembly: is a practical choice when you need reliable performance, warranty support and a cost-effective alternative to genuine OEM pricing. It suits contractors, quarry operators, civil crews, plant hire fleets and workshops that need the PC300LC back on site quickly.
• Fully rebuilt Komatsu travel motor or final drive: may be suitable when available and when repair cost control is important. Rebuilt units are inspected, prepared and tested before supply, making them a useful option for high-hour machines and urgent breakdown repairs.

Tell Arena how your PC300LC is being used — quarrying, bulk earthmoving, civil construction, demolition support, excavation or infrastructure work — and we can help recommend the most suitable replacement option.
