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.

1. OEM Part Number & Machine Compatibility
Original travel motor model: Hitachi HMGC70 two-speed integrated final drive (hydraulic travel motor + 3-stage planetary reduction gearbox)
John Deere OEM interchange part numbers: 9298565 (complete motor+gearbox assembly), 9263594 (standalone travel motor), PG200030 (replacement aftermarket motor code)
Fully compatible large excavator models: John Deere 470G LC, 470 P-Tier
All three serial numbers are iterative supersession upgrade codes, identical mounting flange bolt pattern, heavy-duty sprocket hub interface, hydraulic A/B feed & drain port layout and internal hydraulic calibration; fully cross-replaceable direct bolt-on aftermarket replacement without track frame or pipeline modification
2. Core Technical Specifications
Structure type: Two-speed variable displacement hydraulic travel motor (Stage 1: Low Speed High Torque / Second Stage: High-Speed Travel) + three-stage planetary reduction gear reducer
Dual motor displacement: 78 / 122 cm³/rev
Total gear reduction ratio: 40
Second Stage Specified High-Speed Travel Parameters
Rated working pressure (second stage): 34.3 MPa
Maximum relief pressure (second stage): 36.0 MPa
Rated operating speed (second stage): 2600 rpm
Corresponding rated input power (second stage): 72.4 kW
Max output climbing torque: 38600 N·m
Dual travel speed range: 24~42 rpm, perfectly matched to factory hydraulic system of 47-ton John Deere large excavator platform
Mounting PCD, heavy-duty sprocket tooth size, oil port position strictly conform to John Deere OEM dimensional drawings
Gearbox & motor casing adopt ultra-high-strength thickened ductile iron; internal pistons, valve plates, large planetary gears, carrier and heavy-duty bearings use quenched wear-resistant alloy steel for long heavy-load mining & construction service life
3. Internal Structure & Functional Introduction
Dual-displacement travel motor provides two working modes: Stage 1 low-speed high torque for muddy ground, steep slope climbing, rock excavation and heavy loading; Second-stage high-speed mode for flat ground fast transfer
Built-in large multi-disc spring-applied hydraulic release mechanical parking brake, stable locking performance on ultra-steep slopes to prevent track sliding
Three-stage thickened planetary reduction gear set greatly amplifies hydraulic motor torque to drive heavy track sprocket, stable continuous power output under long mining and heavy digging loads
Integrated built-in anti-cavitation valve and double shock relief valve to absorb violent hydraulic pressure surges, effectively protect motor core components from impact damage during compound actions
Heavy-duty integrated final drive layout fits perfectly inside the reinforced track frame space of JD470G LC / 470 P-Tier large excavators
