You may have seen Doosan excavator easily tear apart some rocks at the mining site or watched how a Doosan wheel loader effortlessly transported mountains of cargo. If so, you definitely noticed one thing about Doosan. Yes, it has been proven by thousands of examples of equipment usage all around the globe, whether it was used to operate in dusty construction sites of the Middle East countries or to work in difficult open-pit mines in Africa. Trusted by numerous heavy equipment spare parts suppliers in UAE, and around the world, Doosan is the reliable companion of every heavy operation.

The company's specialists have vast experience in working with single excavator operators to fleet operators. They know how to perfectly handle any situation, and knowing the most important spare parts and their significance becomes extremely useful. So, let's discuss them in detail.

Engine – The Starting Point

The main part in any Doosan equipment is its engine. The engines manufactured by Doosan can deliver high levels of power and durability. Some parts wear quickly and require frequent replacement.

In the case of fuel injectors, the amount and the pressure of injected fuel directly affect the engine operation. If they have become worn or have been clogged with dirt, it become noticeable by reduced engine productivity, increased fuel consumption, and excessive black smoke in the engine exhaust. Replacement of worn injectors by using parts made by Doosan guarantees the efficient burning of the fuel.

Engine filters, such as oil, air, and fuel filters, are usually not much expensive and, thus, are often neglected. However, neglecting their timely replacement means damaging the engine quickly. A clogged air filter will not provide sufficient fresh air for the engine. A clogged fuel filter will allow particles of dirt to enter the system.

Combustion is facilitated by pistons, piston rings, and cylinder liners. These parts tend to wear out after long hours of operation. As a result, the piston rings will not be able to provide adequate sealing, causing poor compression, reduced power, and increased oil usage. The solution is to replace the rings during an engine rebuild.

Hydraulic Systems – Backbone of Heavy Equipment

The hydraulic system is the reason why a Doosan excavator or a backhoe works efficiently as it does. Every movement made by the boom and every bucket dig is achieved by the movement of pressurized hydraulic fluid throughout the pumps, valves, cylinders, and hoses.

1. It is essential to take good care of expensive hydraulic pumps. They last longer if they have the right level of clean hydraulic fluid. However, once a hydraulic pump stops working – which happens – the only thing to do is immediately purchase a new pump, specifically a genuine Doosan hydraulic pump. In such a way, you will avoid further damage to the rest of the hydraulic system.

2. Hydraulic seals and O-rings might look insignificant at first glance, but they play a crucial role in how your equipment functions. A leaking hydraulic cylinder does not only cause a mess but also lowers the force of your equipment, makes the hydraulic fluid drain faster, and finally damages your cylinder beyond repair. Buying new seals for Doosan cylinders does not cost too much.

3. Control and solenoid valves control the flow of fluid to direct its course. If any of these valves is faulty, there will be no accurate translation of the commands issued by the operator to control the actions of the machine.

The Undercarriage Parts

Mostly it is the undercarriage parts that suffer from the greatest wear and tear. That's because this part of the equipment is always in touch with rocks, mud, gravel, and rough terrain.

The undercarriage wears easily in difficult operating conditions.

1. Track chains, track shoes, and track links make up the most easily recognizable elements of the undercarriage. These elements should be inspected regularly. Cracked and worn track shoes result in loss of traction and even slippage. Excessive stretch of the track chains leads to excessive wear of sprockets and idlers.

2. It is sprockets, idlers, and rollers that help steer and provide necessary tension to the track. If the sprocket wears down, the track will be subjected to faster wear irrespective of its condition. It would be more beneficial to change them all at once rather than separately.

Undercarriage neglect remains one of the most frequent mistakes made when managing heavy equipment, and rebuilding the undercarriage can become rather expensive, consuming a major part of the machine's cost. But by taking care of its condition, you can ensure that you will not have to change the whole unit, but only some parts of it.

Electrical Components - The Nervous System

Current-generation Doosan machinery relies heavily on electronic parts. From monitoring engine temperatures to hydraulic pressures to safety systems for the operator, all these components ensure that everything is working as it should.

1. Sensors such as temperature sensors, pressure sensors, and position sensors provide information directly to the control system of the machine. Malfunctioning sensors can result in false alarms, unnecessary shutdowns, etc. Having spare sensors available will ensure that the machine's brain is always up and running.

2. Starter motors and alternators provide the electricity needed for many vital processes in the machine. If an alternator malfunctions, the battery will not charge, resulting in poor starting and possibly ending up in trouble in remote areas. These are parts that may be kept on hand as spares if you're working in difficult areas.

Why You Should Only Choose Genuine Parts?

In fact, there have been occasions where our customers have tried saving costs by using counterfeit spares. This usually never works out in their favor. The genuine Doosan spares are made within stringent standards and specifications, they fit perfectly well, do what they are meant to, and are backed up with guarantees from the manufacturing company. Counterfeit spares tend to mimic the appearance of genuine products, although they may not be able to meet specifications under load, temperature, and pressure conditions.

We, Mechon International is an authentic Doosan spare parts suppliers in UAE that provides genuine spare parts for Doosan machinery all around the world – from the GCC to Africa. We realize that any downtime with regard to your machine will be costly and hence provide our services through global sources, fast logistics, and transparent pricing policies. Whatever you own, be it one or a fleet of machineries, we will ensure you continue benefiting from your Doosan machines.
