How to Set Hydraulic Pump Pressure on a 100 Hitachi Excavator: A Complete Guide
Hydraulic systems are at the heart of excavators, ensuring optimal performance and efficiency in heavy-duty operations. Setting the correct hydraulic pump pressure is crucial for effective functioning and longevity of your machinery. If you're operating a 100 Hitachi Excavator, understanding how to set its hydraulic pump pressure is essential. In this detailed guide, we'll explore the step-by-step process to set the hydraulic pump pressure correctly, ensuring your excavator functions seamlessly.
Understanding the Importance of Hydraulic Pump Pressure
The hydraulic pump in your Hitachi excavator is a crucial component that translates power into hydraulic energy, enabling the excavator to perform its tasks. Incorrect hydraulic pump pressure can lead to inefficient operation, increased wear and tear, and even potential breakdowns. Therefore, maintaining the correct pressure is vital for sustaining performance and reducing maintenance costs.
Step-by-Step Guide to Setting Hydraulic Pump Pressure
1. Prepare Your Tools:
Before you begin, ensure you have the necessary tools ready—pressure gauges, adjusting tools, and the excavator's service manual. Having the proper tools is essential for a smooth adjustment process.
2. Safety Precautions:
Ensure that the excavator is on stable ground and all attachments are lowered. Turn off the engine and relieve any locked hydraulic pressure by moving the hydraulic controls back and forth.
3. Locate the Hydraulic Pump:
Identify the hydraulic pump assembly based on your Hitachi excavator's manual. Typically, this is situated near the engine compartment.
4. Attach the Pressure Gauge:
Connect the pressure gauge to the appropriate test port on the hydraulic pump. This will help you monitor the current pressure levels accurately.
5. Start the Excavator:
Turn on the excavator and let it idle to warm up the hydraulic system. It's crucial to set the pressure while the system is at operating temperature.
6. Monitor the Pressure:
Observe the pressure on the gauge. Compare it with the specifications provided in the Hitachi excavator manual. This will indicate if an adjustment is necessary.
7. Adjusting the Pressure:
If the pressure reading is outside the recommended range, use the adjusting tools to modify the setting. Typically, this involves turning an adjustment screw or knob to increase or decrease the pressure.
8. Recheck the Pressure:
After adjustments, recheck the pressure to ensure it aligns with the specified parameters. Make any additional tweaks if necessary.
9. Secure Everything:
Once satisfied, turn off the excavator, remove the pressure gauge, and secure any panels or covers you loosened during the process.
10. Test the Excavator:
Operate the excavator briefly, checking for any irregularities in performance. Ensure that all systems are functioning smoothly.
Frequently Asked Questions (FAQs)
Q: Why is setting the correct hydraulic pump pressure important?
A: Proper pressure settings ensure optimal performance, reduce wear and tear, and prevent potential breakdowns.
Q: Can I adjust the hydraulic pump pressure myself?
A: Yes, with the right tools and guidance, you can adjust the pressure. However, consulting with an expert or service engineer is advisable if unsure.
Q: How often should the hydraulic pressure be checked?
A: Regular checks during routine maintenance schedules are recommended to ensure efficient operation.
Q: What causes the pressure to go out of spec?
A: Factors include external damage, wear over time, and incorrect previous settings.
Q: Can incorrect pressure settings affect fuel efficiency?
A: Yes, they can lead to excessive fuel consumption due to inefficiencies in the system's operation.

FAQS
How to replace the filters on an excavator?
After the machine has cooled down, locate the filters that need to be replaced (such as oil, fuel, and air filters). Use tools to remove the old filters, clean the installation area, install the new filters, and ensure they are sealed properly.
Why can't the crankshaft rotate when the excavator starts?
- The starter and flywheel teeth are not meshed well. The ring gear and the starter gear collide when starting the engine, causing tooth damage or single-sided wear of the teeth. If more than three teeth are damaged or worn seriously, it will be difficult for the starter gear and the ring gear to mesh.
2. Cylinder sticking. When the engine temperature is too high, the engine is stopped and the heat is difficult to dissipate. The piston ring at high temperature sticks to the cylinder and cannot start after cooling.
3. Crankshaft lock. Due to lubrication system failure or lack of oil, the sliding bearing rubs dry, which eventually locks the crankshaft and cannot start.
4. The injection pump plunger is stuck.
If i don'thave part number, can you check for me?
Yes, excavator model, old photos, and size are also available to confirm the correct parts you need.
What causes the efficiency of hydraulic pumps to decrease?
The reasons for the decrease in efficiency include wear of internal components, filter blockage, hydraulic oil contamination and insufficient system pressure.
What are the reasons that may cause the excavator engine to emit white smoke?
1. Most of the white smoke is caused by water in the cylinder. Please check whether there is water in the excavator diesel. Generally, the white smoke is emitted for a short time after starting, and there is no problem with the engine;
2. If the excavator starts to emit white smoke, the oil is not reduced, and the excavator works weakly, it means that the cylinder mattress of the excavator engine is worn;
3. Poor atomization of the injector and low cylinder pressure are also one of the reasons for the excavator engine to emit white smoke. Check the injector.
