Si decide comprar maquinaria a un precio inferior, póngase en contacto con el verdadero vendedor. Recopile toda la información que le sea posible sobre el propietario de la maquinaria. Una forma de engaño es presentarse como empresa. En caso de sospecha, infórmenos mediante el formulario de comentarios y sugerencias para que lo comprobemos.
Antes de confirmar una compra, revise detenidamente varias ofertas de venta para ver cuál es el precio medio del equipo elegido. Si el precio de la oferta que le interesa es mucho menor que el de ofertas similares, piénselo dos veces. Una diferencia de precio significativa puede conllevar a defectos ocultos o a un intento de fraude por parte del vendedor.
No compre productos cuyo precio diste mucho del precio medio de equipos similares.
No acepte compromisos dudosos o mercancías con prepago. Si no lo tiene claro, no dude en solicitar aclaraciones, pida fotos adicionales y documentos del equipo, compruebe la autenticidad de los mismos y pregunte todo lo necesario.
Esta es la forma más habitual de fraude. Ciertos vendedores pueden requerir una cantidad del pago por adelantado en concepto de «reserva» de su compra. Así, los estafadores perciben grandes cantidades de dinero y después desaparecen sin dejar huella.
- Transferencia de prepago a la tarjeta
- No realice un pago por adelantado sin documentación que confirme el proceso de transferencia de dinero, si durante la comunicación con el vendedor ha surgido alguna duda.
- Transferencia a una cuenta «fiduciaria»
- Dicha solicitud debe alarmarle, ya que en la mayoría de los casos se trata de fraudes.
- Transferencia a una cuenta de una empresa con un nombre similar
- Tenga cuidado, ya que los estafadores pueden ocultarse tras la identidad de empresas reconocidas, realizando modificaciones mínimas en su nombre. No transfiera dinero si tiene dudas sobre el nombre de la empresa.
- Sustitución de sus propios datos en la factura de una empresa real
- Antes de realizar una transferencia, asegúrese de que los datos especificados sean correctos y que aludan a la empresa en cuestión.

Operating at this 15-to-16-ton scale, the travel drive is responsible for translating the hydraulic flow from your main pump into the immense mechanical torque required to turn the track sprockets, allowing the machine to climb steep gradients and push through deep mud.
1. Part Number & Model Compatibility
These assemblies are direct, factory-spec engineering replacements for the Hitachi Dash-5 midi excavator series:
Hitachi OEM Part Numbers: 4359799, 4389722 (Interchangeable engineering revisions)
Machine Fitment: * Hitachi EX150LC-5
Hitachi EX160LC-5
Assembly Type: Integrated Two-Speed Hydraulic Motor + Multi-Stage Planetary Gearbox
2. Technical Features & Performance Advantages
Sourcing a high-quality original or premium matching direct replacement ensures the mechanical and hydraulic systems mesh perfectly with Hitachi’s factory settings:
Two-Speed Automatic Travel Shift: The integrated motor features an internal swash-plate actuator that automatically or manually shifts between high-displacement/high-torque (low speed for climbing/pushing) and low-displacement/high-speed (for rapid tracking across flat job sites).
Hardened Planetary Gear Train: The track reducer utilizes precision-ground, induction-hardened gears. This metallurgy handles the intense shock loads experienced when the excavator tracks over rocks or uneven concrete debris.
Heavy-Duty Duo-Cone Seals: Floating metal-to-metal (Duo-Cone) seals protect the gear side of the reducer. These premium seals keep valuable gear oil in while locking out abrasive dirt, mud, and water during submerged track operations.
3. Critical Installation & Maintenance Protocols
Because final drives are subjected to massive external dirt and extreme internal pressures, proper commissioning is crucial to preventing premature failure:
Mandatory Case Drain Line Verification: Piston travel motors must return a small amount of bypass oil to the hydraulic tank via a dedicated case drain line. Before mounting the hoses, ensure the case drain line is clear and unobstructed. A blocked or restricted line will blow out the motor's main shaft seal instantly.
Motor Housing Case Priming: You must manually fill the hydraulic motor portion of the drive with clean, filtered hydraulic oil through the highest case drain port before starting the engine or tracking the machine.
Gearbox Oil Fill & Level Check: The planetary reduction side uses heavy gear oil (typically SAE 80W-90 or 90 gear lube) completely separate from the hydraulic oil. Ensure the gearbox is filled to the correct level plug mark prior to operation.
First Gear Oil Change: Brand-new planetary gears experience a brief "break-in" period. It is highly recommended to drain and replace the gear oil after the first 50 to 100 operating hours to flush out initial wear particles, then every 250–500 hours thereafter.
4. Frequently Asked Questions (FAQ)
Are the 4359799 and 4389722 final drives completely identical?
Yes. 4389722 is typically the updated engineering revision from Hitachi, offering upgraded internal bearings and enhanced metal-to-metal duo-cone seals compared to the earlier 4359799 variant. They are 100% interchangeable on the track frame.
My excavator tracks straight but has a loud grinding noise coming from the track frame. What is wrong?
A grinding or clicking noise usually indicates a mechanical failure within the planetary gear reduction unit (Track Reducer), such as a chipped gear tooth or a collapsed bearing, rather than a problem with the hydraulic motor. Stop tracking the machine immediately; catching this early can allow you to rebuild the gearbox before it completely breaks and destroys the main housing.
How is this heavy final drive shipped safely?
Due to the significant weight of a 15-ton class travel drive, each assembly is completely drained of testing fluids, treated with rust-preventative oil, wrapped in thick protective barriers, and bolted securely inside a heavy-duty, steel-banded export wooden crate. We coordinate priority express or sea freight with global carriers to deliver within 3 to 7 business days for air shipments.
