Komatsu PC450LC Final Drive (Travel Motor) – 208-27-00240

Description

Komatsu PC450LC Final Drive (Travel Motor) – 208-27-00240

The Komatsu PC450LC Final Drive is the heavy-duty travel motor assembly that delivers the torque needed to move a 45–47-tonne-class excavator across demanding work sites. It works through the hydraulic motor and reduction gearing to drive the tracks under load, making it a critical part of the machine’s travel system.

The PC450LC is built for large-scale civil construction, quarrying, mining support, bulk earthmoving and heavy excavation applications. When the final drive starts to fail, the excavator may lose travel power, track unevenly, overheat on one side or stop moving during high-load operation. Arena Hydraulic & Machinery supplies replacement Komatsu PC450LC final drives and supports operators looking for a reliable large excavator travel motor supplier in Australia with warranty-backed service and fast freight options.

Warning signs your Komatsu PC450LC final drive may be failing

The PC450LC often works in extreme-load environments such as quarry floors, mine support areas, heavy civil sites, steep haul roads, wet ground and long tracking distances. These conditions can place serious 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 final drive housing, hub seal or cover plate
• 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 moving under heavy load
• Heat building up in one final drive housing after 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 prevent 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: It is a strong option when you need reliable travel performance, warranty support and a cost-effective alternative to genuine OEM pricing. It suits quarry operators, mining support contractors, civil crews, plant hire fleets and workshops that need the PC450LC back on site quickly.
• Fully rebuilt Komatsu travel motor or final drive: It may be suitable when available and when managing repair costs is important. Rebuilt units are inspected, prepared and tested before supply, making them a practical option for high-hour machines and urgent breakdown repairs.

Tell Arena how your PC450LC is being used — quarrying, mining support, bulk earthmoving, heavy excavation, civil construction or large-scale site preparation — and we can help recommend the most suitable replacement option.
