Heavy-Duty Travel Motor Assembly for Kobelco 20-Ton Excavators

Restore the ultimate pulling power and smooth travel operation of your Kobelco excavator with our premium aftermarket YN15V00011F4 Final Drive Assembly. Explicitly engineered for the Kobelco SK200-6E and SK210-6E series, this complete drop-in replacement guarantees OEM-level hydraulic efficiency and mechanical durability without the heavy dealer markup.

Why Choose Our YN15V00011F4 Final Drive?

• Nabtesco Equivalent Quality: Built around a high-performance axial piston motor architecture (equivalent to the industry-standard GM35 series), ensuring maximum torque output at the rated 34.3 MPa system pressure.

• Dual-Speed Functionality: Fully equipped with the auto-shifting two-speed valve to seamlessly switch between high travel speed and low-speed heavy torque climbing.

• Symmetrical Design: This motor group is completely interchangeable and can be installed on either the Left or Right side of the undercarriage with zero modifications.

• Rugged Planetary Gears: The multi-stage planetary reduction gearbox utilizes 20CrMnTi heat-treated steel, providing exceptional resistance against shock loads in harsh mining or earthmoving environments.

(Note: This unit is for the "6E" generation. It is NOT compatible with earlier Mark VI (SK200-6) or later Dash 8 (SK200-8) models due to differences in displacement and flange patterns.)

6. Installation & Maintenance Guidelines

To validate your 6-month warranty and ensure the longevity of your new travel motor, please adhere strictly to these installation procedures:

1. Case Drain Line Clearance (CRITICAL):Before starting the machine, you must thoroughly clean and blow out the case drain line. The back-pressure in the drain line must not exceed 0.2 MPa (2 bar). A restricted case drain will instantly rupture the internal floating seal, allowing hydraulic fluid to flood the gearbox. This is the #1 cause of premature failure.

2. Pre-fill the Hydraulic Motor:Never start the travel motor dry. Before connecting the main hydraulic hoses, pour clean hydraulic oil directly into the motor's highest case drain port to lubricate the internal piston group and brass valve plate.

3. Fill the Planetary Gearbox:The reduction gearbox is shipped completely dry. You must fill the gear section with approximately 4.5 Liters of SAE 90 or 80W-90 (API GL-5) gear oil. Fill through the top plug until oil weeps out from the middle level plug. Do NOT overfill (do not fill with 17 Liters!).

4. Initial Run-In:Raise the track off the ground and operate the travel pedals slowly in both forward and reverse for 5-10 minutes to bleed any trapped air from the system before applying a load.
