This is our PC200-6 Final Drive. Affordable and perfectly matched to the PC200-6 excavator, it boasts high quality, high wear resistance, and guaranteed after-sales service. Factory stock available for fast shipping, OEM/ODM supported.
Regarding its location:
If you view it from the side of the excavator, the travel assembly is mounted at one end of the track frame. Typically:
The front end is the idler wheel, responsible for tensioning the tracks.
The rear end is the travel assembly, which provides drive power through the engagement of the track pads with the gear ring.
Its composition: It consists of two parts:
- Travel motor: It receives pressurized oil from the main pump, converting hydraulic energy into rotational mechanical energy.
- Travel gearbox: It reduces the high-speed rotation of the motor while significantly increasing torque to move the heavy machine body.
How to Identify a High-Quality Final Drive:
1.Observe the Machining Precision of the Final Drive
- Gear Material and Heat Treatment: High-quality gears are typically made of high-strength alloy steel (such as 20CrMnTi) and undergo deep carburizing and quenching. Observe the tooth surface; high-quality gears have an extremely high surface finish, appearing slightly bluish or dark gray, without machining marks.
- Floating Seals: This is the last line of defense against mud and sand ingress and gear oil leakage. High-quality floating seal rings are made of wear-resistant and elastic material, with a flat mounting surface and no burrs.
2. Test the Performance of the Hydraulic Motor
- Volume Efficiency (Internal Leakage): This is a core indicator. A high-quality motor has minimal internal leakage when climbing hills under full load, maintaining stable output. This can be judged by testing the overflow pressure: a motor that easily reaches the set value and maintains stable pressure is of better quality.
- Starting Torque: Observe whether the excavator starts slowly under heavy load. A high-quality motor has extremely high starting torque, providing instantaneous burst of power.
3. Detailed Workmanship and Housing Strength
- Casting Quality: A high-quality motor case uses high-grade cast steel or ductile iron, with a thick outer wall and a well-designed heat dissipation fin. The surface should be free of pores, sand holes, or repair marks.
4. Operational Status Monitoring
- Operating Noise: A high-quality motor assembly emits a uniform, low-pitched "humming" sound. Sharp metallic friction sounds or periodic knocking sounds indicate substandard gear precision or the presence of foreign objects.
Recommendation: When evaluating a motor assembly, in addition to checking its appearance and testing its performance, brand reputation and past installation feedback are crucial factors. Especially for easily damaged core components like the motor, choosing a manufacturer with OEM quality standards can significantly reduce subsequent downtime maintenance costs.
