The Komatsu PC170LC-11 Final Drive is the drive component that helps transfer hydraulic power into the turning force needed to move your excavator tracks. Also searched as a Komatsu track drive, Komatsu drive motor, or Komatsu final drive motor, this assembly plays a critical role in keeping your excavator travelling smoothly across the job site.
Built for a modern 17-tonne-class excavator, the PC170LC-11 is commonly used in construction, earthmoving, trenching, drainage, roadworks and infrastructure projects. When the final drive starts to lose power, leak oil, or make noise, the machine can become slow, uneven or unsafe to operate. Arena Hydraulic & Machinery supplies replacement Komatsu PC170LC-11 final drives and supports contractors looking for a reliable hydraulic travel motor supplier in Australia with warranty-backed service and fast freight nationwide.
If you are looking for a complete final drive excavator Komatsu replacement, Arena can help verify the correct unit before dispatch.

Final drives work under constant pressure, especially when the excavator is travelling through mud, rock, slopes, uneven ground or long job site distances. Common warning signs include:
Replacing a worn final drive early can help protect the planetary gears, bearings, sprocket, track chain and hydraulic travel circuit from further damage.
A new aftermarket Komatsu final drive assembly is a strong option when you want dependable performance, warranty support and a cost-effective alternative to genuine OEM pricing. It suits contractors, mechanics and fleet operators who need to reduce downtime without compromising reliability.
A fully rebuilt Komatsu travel motor or final drive may be suitable when available and when the repair budget is a key consideration. Rebuilt units are inspected, prepared and tested before supply, making them a practical option for working machines that need to return to site quickly.

Need a replacement final drive for your Komatsu PC170LC-11 excavator?
Send Arena Hydraulic & Machinery your machine model, serial number, photos of the existing final drive and any visible part numbers. We will check the details, confirm the best replacement option where possible, and provide pricing, warranty information and delivery options.
Q: What final drive suits the Komatsu PC170LC-11?
A: The correct final drive can depend on the machine serial number and the numbers stamped on the existing unit. Because the client has not provided a confirmed part number, Arena recommends sending your serial number and photos before ordering.
Q: Is a final drive the same as a travel motor?
A: They are closely related, but not always the same part. The travel motor is the hydraulic motor section, while the final drive assembly includes the reduction gearing that multiplies torque and turns the track. Many customers still search for the complete unit as a Komatsu travel motor, track drive or drive motor.
Q: Does Arena supply genuine OEM Komatsu PC170LC-11 final drives?
A: Arena supplies high-quality aftermarket and rebuilt replacement final drive options, not genuine Komatsu OEM unless specifically stated. Supplied units are backed by a warranty.
Q: What are the common symptoms of final drive failure?
A: Common symptoms include oil leaks, grinding or whining noises, weak travel, uneven tracking, overheating, metal in the gear oil or one side of the excavator losing drive. These signs should be checked quickly to avoid more expensive damage.
Q: Can Arena help confirm the right unit before dispatch?
A: Yes. Send your machine serial number, photos of the current final drive and any stamped identification numbers. Arena can use these details to help confirm the correct replacement before dispatch.
Q: Do you deliver Komatsu final drives Australia-wide?
A: Yes. Arena Hydraulic & Machinery is based in Melbourne and can arrange freight across Australia, including major cities, regional areas and suitable job sites.
Q: What information should I send for a quote?
A: Send your machine model, serial number, photos of the existing final drive, stamped part numbers if visible and your delivery location. This helps Arena provide a more accurate quote and fitment confirmation.
