Excavator Identification

Before picking the right excavator hydraulic pump parts, you need to know some important facts about your machine. This step helps you avoid mistakes and makes sure you get the right parts for your excavator.
Make, Model, Serial Number
First, find out your excavator’s make, model, and serial number. These are usually on a metal plate on the machine. You can also look in your owner’s manual. Give this information to your supplier. They can use it to find the right parts for your machine.
Tip: A good supplier will use your machine’s serial number to find the right part. Many suppliers have systems that match serial numbers to parts. You should also check part numbers in manuals or diagrams.
People sometimes make mistakes when getting this information:
They forget to check the manufacturer’s number on the hydraulic pump’s nameplate.
They only use part numbers from manuals.
They mix up part numbers that look alike.
If you do not make these mistakes, you will save time and money.
Hydraulic Pump Type
You also need to know what type of hydraulic pump your excavator uses. Pumps may look the same, but small differences matter. If you pick the wrong pump type, you could have problems like fluid incompatibility. This can make your pump work badly or even break.
Manufacturer Number
The manufacturer number is important too. You can find it on the hydraulic pump’s nameplate. This number helps you and your supplier make sure you get the exact part you need. Giving the manufacturer number lowers the chance of ordering the wrong part.
When you have all this information, it is much easier to find the right excavator hydraulic pump parts. YNF Machinery can help you match your machine to the correct parts fast and easily.
Hydraulic Pump Selection

Picking the right excavator hydraulic pump parts means you need to know your machine’s needs. You should look at important details like pressure and flow rate. Make sure the pump matches what you want to do. This helps you avoid mistakes that cost money. It also keeps your excavator working well.
Specifications Checklist
Check some important things before you choose excavator hydraulic parts. Use this list to help you pick the right hydraulic pump:
Specification | Description |
---|---|
Pressure Rating | Pick a pump with a pressure rating higher than your excavator needs. This keeps things safe. |
Flow Rate | Make sure the flow rate fits your excavator’s needs. This helps it work its best. |
Pump Size | The pump size must fit your excavator’s system. This stops problems when you use it. |
Safety Margins | Use a safety factor three to four times the working pressure. This helps with sudden spikes. |
Environmental Factors | Think about how temperature changes the hydraulic fluid. Make sure the fluid works with your pump. |
Contamination Control | Use good filters and check often. This keeps dirt and water from hurting your pump. |
Always check the hydraulic lines and fluid before you put in new excavator hydraulic pump parts. This helps you find leaks or dirt that could hurt your new pump. Checking and cleaning often keeps your system working well.
Pressure and Flow Rate
Pressure and flow rate are very important for hydraulic pumps. These numbers show how much force and speed your excavator hydraulic pump can give. Different excavators and jobs need different settings.
A medium excavator may need up to 150 gallons per minute and 4,500 psi.
The hydraulic system design is different for each model. This changes how your machine works.
New excavators use smart systems. These change flow and pressure for each job.
The main pump must give enough flow to keep pressure steady.
You need to know the highest flow rates for the boom, swing motor, and bucket cylinder.
If you pick a pump with the wrong pressure or flow rate, you might see these problems:
Less force, so cylinders cannot lift as much.
Slower work times.
The machine may act strange.
The system may get too hot.
The pressure may not stay steady when working hard.
Other problems can happen too. Vapor bubbles can form in the fluid. Metal parts can wear away. Dirt can get in the system. Cavitation happens when the pump cannot give enough fluid. This makes vapor bubbles that can hurt your hydraulic pump and excavator hydraulic cylinder.
Always check the hydraulic lines and fluid for leaks, dirt, or water. Clean lines and good fluid protect your new main hydraulic pump. They also help your excavator hydraulic cylinder work well.
Application Needs
You need to match your hydraulic pump to your job. The best pump for heavy digging may not be good for careful grading. The hydraulic system gives your excavator the force for every job. High pressure gives more force for tough digging. High flow lets you move faster for jobs like grading.
It is important to know the difference between hydraulic pressure and flow. More pressure gives more force for hard jobs. More flow lets you move faster for jobs that need speed.
Think about what you want your excavator to do:
Heavy digging needs high pressure.
Fast grading needs high flow.
Deep or wide digging may need special pump sizes.
Always match your excavator’s details to your project.
Wear, leaks, heat, and dirt can make you change excavator hydraulic pump parts more often. Good care helps your hydraulic pump last longer. Find the right pump for your job and check it often.
YNF Machinery can help you pick the best excavator hydraulic pump parts for any job. Their team knows about hydraulic pump selection. They can help you choose the best parts for your excavator and your work.
Excavator Hydraulic Pump Parts Compatibility
Picking the right hydraulic pump means knowing how parts fit together. You need to check if parts are OEM or aftermarket. Look at part numbers and see if they match your machine. This helps stop problems with your excavator hydraulic pump. It also keeps your excavator hydraulic cylinder working well.
OEM vs Aftermarket
When you buy excavator hydraulic pump parts, you have two choices. OEM parts are made by the original company. Aftermarket parts are made by other companies. Both types have good and bad points.
Here is a table to help you compare:
Characteristic | OEM Parts | Aftermarket Parts |
---|---|---|
Performance and Longevity | Made for best performance and to last in tough places. | Quality can change based on who makes them. |
Longevity | Last longer, so you do not replace them often. | May need to be replaced more, costing more over time. |
Compatibility | Made to fit just right, so they work well. | Fit many models, but may not be as exact as OEM. |
OEM parts fit best and work well. They last a long time and are high quality. Aftermarket parts cost less, sometimes 20%–60% cheaper than OEM. The price changes with brand, warranty, and how good they are. Pick aftermarket parts from a trusted seller for good quality. YNF Machinery sells both OEM and good aftermarket parts for your excavator hydraulic pump. You can get the right hydraulic pump and repair kits for many excavators.
Cross-Referencing Part Numbers
