Technical Spotlight: Excavator Slewing Ring (回转支承)
An Excavator Slewing Ring, also known as a swing bearing or turntable bearing, is a large-diameter rotational rolling-element bearing that supports the upper structure of the excavator (the house) and allows it to rotate 360 degrees on its undercarriage. It handles immense axial, radial, and moment loads simultaneously. Example: Hitachi ZX470-3 Swing Circle Slewing Ring (日立ZX470-3回转支承) is mounted between the excavator's carbody and the revolving upper frame.
Russian: Поворотный круг экскаватора Hitachi ZX470-3

Field Diagnosis: John Deere 8320R Tractor Hydraulic System Failure
Symptom: A John Deere 8320R tractor is experiencing weak and slow response from its hydraulic implements (e.g., the three-point hitch lift), accompanied by a whining noise from the hydraulic pump area, especially under load.
Possible Causes:
- Low Hydraulic Fluid: The most common and easiest cause to check.
- Clogged Hydraulic Filter/Strainer: Restricts flow to the pump, causing cavitation (which creates the whining noise).
- Failed Hydraulic Pump: Internal wear and tear can reduce the pump's efficiency, leading to low pressure and flow.
- Pressure Relief Valve Issue: The valve might be stuck open or have a weak spring, preventing the system from building up to the required pressure.
- Air in the System: A leak on the suction side of the pump can introduce air, leading to spongy and erratic hydraulic performance.
Resolution Steps:
- Check Fluid Level: With the tractor on level ground and implements lowered, check the hydraulic oil sight glass. Top up with the correct John Deere Hy-Gard fluid if low.
- Inspect and Replace Filters: If the fluid level is correct, replace the main hydraulic oil filter. Check service records; if it hasn't been changed recently, it's a likely culprit. Also, inspect the suction screen within the reservoir for debris.
- Check for Leaks: Carefully inspect all hydraulic lines, especially those leading to the pump, for any signs of leakage or wetness that could indicate an air leak.
- Test System Pressure: If the problem persists, the next step is to test the system's standby and operating pressures using a hydraulic pressure gauge connected to the SCV ports. Compare the readings to the manufacturer's specifications. If the pressure is low, it points towards the pump or relief valve.
- Isolate the Issue: A faulty pressure relief valve can be diagnosed by a professional mechanic. If the valve is functioning correctly and pressure is still low, the main hydraulic pump has likely failed and will require replacement. At Growshine International, we can source high-quality replacement hydraulic pumps for agricultural machinery.

Technical Spotlight: Final Drive (终传动)
The Final Drive is a critical undercarriage component in tracked vehicles like excavators and bulldozers. It is a gearbox assembly that provides the final speed reduction and torque increase to the tracks, allowing the machine to move. It consists of a hydraulic motor and a planetary gear system. Example: The Caterpillar D8T Bulldozer Final Drive (卡特彼勒D8T推土机终传动) is located at the rear of the track frame and is connected to the sprocket which drives the track chain.
