Accessory Definitions
Understanding the components is key to maintenance and repair. Here are definitions for some common heavy machinery parts:
- Hydraulic Pump: Converts mechanical power from the engine into hydraulic energy by pressurizing fluid.
Location: Often mounted to the engine flywheel housing or gearbox.
Example: Komatsu PC200-8 Hydraulic Main Pump. 小松 PC200-8 液压主泵. Комацу PC200-8 Гидравлический главный насос. - Swing Motor: A hydraulic motor that provides rotational power to the excavator's upper structure, allowing it to swing.
Location: Inside the swing gearbox, connected to the swing bearing.
Example: Kubota KX040-4 Swing Motor. 久保田 KX040-4 回转马达. Кубота KX040-4 Поворотный двигатель. - Final Drive: The last component in the drivetrain, converting hydraulic or mechanical power into rotational torque to move the tracks or wheels.
Location: At the rear end of the tracks or wheels.
Example: Kubota KX040-4 Final Drive. 久保田 KX040-4 终传动. Кубота KX040-4 Бортовой редуктор. - Control Valve: A hydraulic valve that directs the flow of pressurized fluid to various actuators (cylinders, motors) to control machine movements.
Location: In the main control valve block, typically centrally located.
Example: Komatsu PC1100 Main Valve. 小松 PC1100 主阀. Комацу PC1100 Главный клапан. - Gearbox: A mechanical system containing gears to change speed and torque between an input and output shaft.
Location: Used in swing mechanisms, travel drives, transmissions, etc.
Example: Caterpillar E320D2 Swing Gearbox. 卡特彼勒 E320D2 回转减速机. Катерпиллер E320D2 Механизм поворота. - Transmission Pump: A pump that supplies hydraulic pressure or lubrication to the transmission system.
Location: Part of the transmission system.

Example: Komatsu WA600-6 Hood Hydraulic Fan Motor Pump. 小松 WA600-6 散热器液压风扇马达泵. Комацу WA600-6 Гидравлический мотор вентилятора капота. - Pilot Pump: A small hydraulic pump that provides low-pressure control oil to operate the main control valves.
Location: Often attached to the main hydraulic pump.
Example: Volvo EC700 Hydraulic Gear Pump Pilot Pump. 沃尔沃 EC700 液压齿轮泵(先导泵). Вольво EC700 Гидравлический шестеренчатый насос (пилотный). - Regulator: A component on a hydraulic pump that controls its output pressure or flow based on system demand.
Location: Mounted directly on the main hydraulic pump.
Example: Hitachi EX200-5 Hydraulic Pump Regulator. 日立 EX200-5 液压泵调节器. Хитачи EX200-5 Регулятор гидравлического насоса. - Piston: A cylindrical component that moves back and forth within a cylinder or bore, displacing fluid in pumps or converting fluid pressure into linear motion in cylinders.
Location: Inside hydraulic pumps (piston pumps) and hydraulic cylinders.
Example: Caterpillar 314C Hydraulic Pump (uses pistons). 卡特彼勒 314C 液压泵 (使用柱塞). Катерпиллер 314C Гидравлический насос (использует поршни).
Common Questions & Tips
Here are some questions customers often ask:
- How do I identify the correct part number for my machine? Always check your equipment's service manual or the existing part tag. If unsure, contact us with your machine model and serial number.
- What are the signs my hydraulic pump is failing? Look for slow or weak hydraulic functions, increased noise from the pump, overheating hydraulic fluid, or leaks.
- Is it necessary to replace related parts when changing a main component like a hydraulic pump? Often, yes. Contaminated oil or a failing related component can quickly damage a new pump. Consult your service manual or a technician.
Troubleshooting Example: Excavator Losing Hydraulic Power
Problem: Your Excavator, such as a Komatsu PC200, is experiencing a significant loss of hydraulic power, leading to slow and weak movement of the boom, arm, or bucket.
Symptoms:
- Slow operation compared to normal.
- Inability to lift heavy loads or dig effectively.
- Potential increase in engine RPM without corresponding hydraulic speed.
- Sometimes accompanied by unusual noises from the hydraulic pump area.
Possible Causes:
- Low hydraulic fluid level or contaminated fluid.
- Clogged hydraulic filter or strainer.
- Worn or damaged Hydraulic Main Pump (708-2L-00300 7082L00300).
- Issue with the main Control Valve or relief valves.
- Problem with pump regulators or pressure sensors.
- Internal leaks within cylinders or motors.
Basic Steps & Treatment:
- Check Hydraulic Fluid Level: Ensure the hydraulic reservoir is filled to the correct level with the specified fluid type.
- Inspect/Replace Filters: Check and replace the hydraulic filter and possibly clean the strainer.
- Visual Inspection: Look for obvious leaks in hoses, fittings, cylinders, or the pump.
- Professional Diagnosis: If simple checks don't resolve the issue, a qualified technician is needed to check system pressures, pump performance, and control valve function using specialized equipment. Replacing a Hydraulic Main Pump (708-2L-00300 7082L00300) is a complex task and should be done by a professional.
Proper maintenance and using high-quality replacement parts from suppliers like Growshine are crucial to prevent such failures.
