Hyundai R290-7 R305-7 XJCK-00136 XJCK-00081 Final Drive Assembly For Crawler

Product Specification

Hyundai R290-7 R305-7 XJCK-00136 XJCK-00081 final drive Assembly for Crawler Excavators

The travel gearbox operates as a speed reducer and torque amplifier:

1. Power Input: Receives high-speed, low-torque rotational energy from the hydraulic motor (or engine via a driveshaft in mechanical systems).

2. Gear Reduction: Multi-stage gears (planetary/spur) reduce speed while increasing torque.

3. Output to Sprocket: The final drive transfers torque to the sprocket, which engages with the track links, propelling the excavator.

4. Direction Control: Integrated clutches or hydraulic valves enable forward/reverse movement.

Hydraulic excavators commonly use hydraulic travel motors coupled with gearboxes, while older models may employ mechanical transmissions.

2. Lubrication:

   • Use recommended oil/grease (e.g., ISO VG 68 for hydraulic systems).

   • Monitor for metal particles (indicate internal wear).

3. Component Replacement:

   • Replace worn gears/bearings promptly.

   • Upgrade to reinforced parts for heavy-duty use.

4. Alignment Checks:

   • Misaligned shafts accelerate wear.
