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.

Product Overview
The Komatsu PC270LC-8 PC270-8 sits just below the 30‑ton class — a 27‑ton long‑undercarriage excavator chosen for pipe‑laying, bridge work and mass excavation where extra stability matters more than maximum digging depth. The axial piston motor and planetary reducer under each track, covered by references 207‑27‑00470 and 708‑8H‑00350, is what gives it that steady mobility: turning hydraulic flow into the low‑speed, high‑torque rotation pulling the long frame across uneven ground. On a mid‑heavy Komatsu worked hard, drive wear tends to surface gradually rather than catastrophically. One track lags, the machine pulls off line on level ground, the drive housing runs warmer than its opposite after a run, and a note from inside the track frame builds with load. Waiting until a track actually slips only scores the piston group and reduction gears further. This aftermarket drive reproduces the original motor‑and‑reducer pairing as one sealed, bench‑tested assembly, so the worn unit lifts out and the new one bolts straight back in.
Core Advantages
1. Stability‑matched output for a long‑undercarriage machine
The LC undercarriage spreads weight over a longer track base, and the drive has to deliver even torque to both sides without one lagging. A lapped piston group holds pressure internally, so both tracks push in step rather than crab‑walking.
2. Hardened gears built for pipeline and bridge‑site duty
The planetary gear set uses case‑hardened, precision‑cut gears with controlled backlash. Smooth meshing spreads drive torque across several teeth at once — what keeps the reducer quiet and durable through years of ramp climbs and trench pushing.
3. Sealed for the mud and water of infrastructure sites
Pipe‑laying and bridge work expose the drive to mud, standing water and fine silt. Correct output‑shaft and housing seals keep that grit out of the motor and gear oil — the protection that decides whether the drive reaches its service hours.
4. One complete tested unit for a clean swap
Motor and reducer arrive pre‑assembled and bench‑checked for torque, leakage and noise. The fitter unbolts the old drive and bolts on the new one without matching separate components — important when a machine that earns by the hour is parked.
5. Aftermarket value for a well‑worked ‑8 series machine
An original Komatsu final drive exchange carries a premium. This aftermarket unit restores track mobility at a fraction of the cost, with sample supply and batch pricing for workshops keeping several PC270LC-8 PC270-8 machines on the books.
Manufacturing & Quality Control
Production follows controlled specification: material certificates on incoming steel, precision CNC machining of housings and gears, case hardening of all wear surfaces, and clean‑area assembly. Each finished drive is loaded on a test rig to run output torque, internal leakage and noise checks; units outside the acceptance window are rejected. Completed assemblies get anti‑rust preservation, moisture‑proof sealing and shock‑absorbing export crating, so they reach the workshop ready to bolt on.
Frequently Asked Questions
Q1: How do I confirm which part number fits my machine？
A: Read the tag on your existing drive against 207‑27‑00470 or 708‑8H‑00350 and send the machine serial number. Komatsu build variants can differ, so we confirm the correct unit before dispatch.
Q2: Does this arrive as the complete drive?
A: Yes — the listing is the full axial piston motor and planetary reducer as one bolt‑on assembly. If you need only internal parts, ask and we will check availability.
Q3: What symptoms mean the drive is wearing out?
A: Mismatched track speeds, pulling to one side on level ground, a hot or noisy track motor and tracks that hesitate under load. Catch it early, before worn debris circulates through the travel circuit.
Q4: What voids the warranty?
A: Manufacturing and material defects are covered. Damage from dirty oil, debris in the motor, track obstruction, forcing a stalled drive, overload or incorrect installation is excluded. Photograph any arrival damage before uncrating.
