Редуктор хода Nabtesco GM06VA Travel motor 22H-60-13110 для мини-экскаватора Komatsu PC56-7

Nabtesco GM06VA Final Drive for Komatsu PC56-7 | OEM Part No. 22H-60-13110 22H-60-13112

1. Product Overview
The Nabtesco GM06VA is a premium, integrated hydraulic transmission featuring a two-speed axial piston motor and a multi-stage planetary gearbox. As the original equipment (OEM) for the Komatsu PC56-7, this unit is engineered to manage the weight and power of 5-ton to 6-ton class machines. It provides the high tractive effort required for heavy-duty grading while maintaining the precise, synchronized tracking necessary for straight-line travel.

(Also compatible with certain PC50MR-2 and PC55MR-2 variants; please verify via serial number).

3. Technical Specifications & Performance
Motor Type: Variable displacement axial piston motor with integrated 2-speed travel (High/Low) switching.

Reduction System: High-torque planetary reduction gears manufactured from induction-hardened alloy steel for superior fatigue resistance.

Max Pressure: Rated for continuous operation up to 28.0 MPa (280 bar) to ensure original factory breakout and tracking force.

Sealing: Equipped with premium Duo-Cone mechanical floating seals to protect the internal gearbox from mud, water, and abrasive grit.

Braking: Integrated spring-applied, hydraulic-release wet disc parking brake for failsafe holding on steep inclines.

4. Why Partner With a 13-Year Industry Expert?
Nabtesco OEM Authenticity: We provide the genuine GM06VA series, ensuring the internal valve plates and piston sets match the original Komatsu hydraulic curve. This prevents the "pulling" or "drifting" common with low-quality aftermarket drives.

100% Bench Testing: Every unit undergoes a rigorous performance test on a hydraulic bench. We verify volumetric efficiency, brake holding torque, and smooth 2-speed shifting before the unit is crated.

Factory-Direct Value: Access Original New units at competitive wholesale prices, providing a high-quality alternative to the significant markups of local dealerships.

Global Rapid Logistics: Units are secured in reinforced, shock-proof export wooden crates. Express delivery via DHL, FedEx, or UPS typically arrives in 3 to 7 business days.

5. Critical Installation & Maintenance Protocol
Gear Oil Commissioning (Crucial): Final drives are typically shipped without gear oil. You must fill the planetary gearbox with SAE 80W-90 gear oil to the correct level before operation.

Case Drain Connection: Ensure the case drain line is clear and connected to the correct port. Excessive backpressure in the motor case is the leading cause of shaft seal failure.

Hydraulic System Flushing: If the previous motor failed due to internal "grenading," the hydraulic tank and lines must be flushed. Residual metal fragments will destroy a new motor almost immediately.

Air Bleeding: After installation, lift the track off the ground and run the motor at low speed in both directions for several minutes to purge air from the hydraulic circuit.

6. Ordering & Professional Support
Fitment Verification: To ensure 100% accuracy, please provide your Machine Serial Number and the number of sprocket mounting holes (commonly 9 or 12).
