Nabtesco GM06VA Travel motor 22H-60-13110 final drive for Komatsu PC56-7 mini excavator
If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

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.
2. Comprehensive OEM Part Number Compatibility
This assembly is a 100% direct "bolt-on" replacement for the following Komatsu factory part numbers and Nabtesco model codes:
Komatsu Part Numbers:
22H-60-13110 / 22H6013110
22H-60-13112 / 22H6013112
22H-60-13100 / 22H6013100 (Early series compatibility)
Nabtesco Model Code:
GM06VA-A-27/45-1
(Specifically configured for the Komatsu PC56-7 sprocket and hydraulic porting).
Machine Fitment:
Komatsu PC56-7
Komatsu PC56-7-40
(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).
Instant Quote: Contact us today for up-to-date pricing, availability, and tiered quality options.
Technical Guidance: Our expert team is available 24/7 to assist with installation procedures, pressure setting adjustments, and hydraulic troubleshooting.
