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 PC300‑7 is a 30‑to‑35‑ton excavator that has become a staple on mining overburden, large earthworks and quarry loading sites — a machine built to run long shifts under hard loading. The final drive under each track, covered by Komatsu references 207‑27‑00413, 207‑27‑00412, 207‑27‑00411 and 207‑27‑00410, is the unit that turns hydraulic flow into the slow, high‑torque rotation pulling that much weight across rutted ground. On a machine this size, drive wear does not creep in quietly. One track lags, the machine wanders on level ground, the drive housing runs noticeably hot after a shorter run than usual, and a deepening note comes from inside the track frame. Continuing to work scores the piston group and reduction gears further, and worn metal then circulates through the travel circuit. These four references cover the drive and its internal sub‑assemblies across the ‑7 build run; this aftermarket unit reproduces the original motor‑and‑reducer pairing as one sealed, bench‑tested assembly, so the worn drive comes off and the new one bolts straight back on.
Core Advantages
1. Output torque matched to a 30‑ton overburden machine
The PC300‑7 carries real weight and meets real resistance on grades and broken quarry ground. Hardened gears and piston surfaces hold the sprocket torque the tracks need to push and climb, without the laboured travel that undersized replacements produce.
2. A piston group that holds pressure under long shifts
The cylinder block, piston shoes and valve plate are lapped to tight running clearances, so hydraulic pressure does not leak internally through the motor. Both tracks then pull in step — no drift, no slow side, no hesitation the moment the bucket digs in.
3. Sealed for quarry dust and standing water
Heavy Komatsu machines work through double shifts in quarry dust, mud and standing water. Fitted output‑shaft and housing seals keep grit out of the motor and reducer — the protection that decides whether a final drive lasts its service life or fails early.
4. One complete, tested unit for a fast turnaround
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 — critical when a stationary 30‑ton machine is losing money by the hour.
5. Aftermarket value for a high‑hour heavy fleet
An original Komatsu final drive exchange carries a serious price. This aftermarket unit restores track mobility at a fraction of the cost, with sample supply and batch pricing for workshops keeping several PC300‑7 machines on the books.
Manufacturing & Quality Control
Every drive is built under controlled production: incoming steel is certified, housings and gears are precision‑machined to drawing tolerances, wear surfaces are case‑hardened, and assembly happens in a clean area. Before packing, each unit runs on a test rig to verify output torque, internal leakage and running noise; anything outside acceptance limits is rejected. Completed drives are preservation‑coated, moisture‑sealed and shock‑crated for sea and overland freight, so they arrive ready to install.
Frequently Asked Questions
Q1: Which of the four references suits my machine?
A: Check the tag on your existing drive against 207‑27‑00413 / 00412 / 00411 / 00410 and share your machine serial number. The references cover build variants and internal sub‑assemblies, 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 only need the motor cartridge or the gearbox internals, ask and we will check availability.
Q3: What should a fitter check after installation?
A: Confirm mounting bolts are torqued to spec, refill the travel circuit to the correct oil level, bleed air from the motor, and run a slow no‑load track test before working under full load. Follow the Komatsu service manual.
Q4: What is covered under warranty?
A: Manufacturing and material defects are covered. Damage from contaminated oil, debris entering the motor, track obstruction, forcing a failed drive, overload or incorrect installation is excluded. If a drive fails on arrival, photograph it and contact us before stripping it down.
