Essential Parts for Your Machine's Hydraulics

A machine's hydraulic system is its lifeblood. At Growshine International, we offer a vast selection of seal kits and components to maintain and repair this critical system. For example, the **Komatsu PC200-6 travel motor seal kit** is essential for preventing hydraulic fluid leaks in the travel motor, which is located in the undercarriage. Another key component is the **CAT 320B swing motor seal kit**, which seals the swing motor responsible for the excavator's rotation. Don't forget the **Hydraulic gear pump seal kit** for models like the **DH370-7**, ensuring the gear pump can efficiently pressurize the hydraulic fluid. For the main pump, the **HPV95 PC200-6 hydraulic pump seal kit** is a popular choice for routine maintenance. Keep your equipment's hydraulic system in top condition with our range of **excavator hydraulic pump parts** and **hydraulic motor seals**.

We've also got you covered for specific models like the **PC40-7 Gear Pump Seal Kit** and **PC60-7 Gear Pump Seal Kit**, which are crucial for the pilot pump systems on these popular Komatsu excavators. For Caterpillar, we supply the **CAT E320 E312 E312B Gear Pump Seal Kit**. Growshine's product range also includes the **JCB3DX Gear Pump seal kit** with part numbers **4206167** and **KP10**, vital for JCB equipment. In addition, we carry **Hydraulic gear pump seal kit 705-17-04440 7051704440** for **WA470-3** and **WA600** wheel loaders, and **705-17-03440 7051703440** for **WA430-6** and **WA380-3** loaders.

Here are a few common questions our customers ask:

• How often should I replace hydraulic seals? The replacement frequency for hydraulic seals depends on the machine's usage and operating environment. It's best practice to inspect them during routine maintenance and replace any that show signs of wear, cracking, or leakage. Proactive replacement can prevent costly downtime.
• Why is my excavator's main pump leaking? A leaking main pump, such as on a **Komatsu PC200-7**, often indicates a failed seal kit. The **PC200-7 PC220-7 Excavator Main Pump Seal Kit 708-2L-00300 7082L00300** is a common replacement part for this issue. A worn-out carbon ring seal is a primary culprit.
• What's the difference between a pilot pump and a main pump? The pilot pump is a small gear pump that provides low-pressure hydraulic fluid to the control valves, allowing the operator to control the main hydraulic functions. The main pump, on the other hand, is a high-pressure pump (often a piston pump) that generates the immense power needed for the excavator's primary movements like digging and lifting.

Comprehensive Solutions for Excavator Maintenance

Beyond the hydraulic pumps, we supply a wide array of other crucial seal kits. Our **swing motor seal kits** are a must-have for any repair shop, including the **M2X120B SK200-5/6** seal kit and the **JMF-15 R225-7/9 swing motor seal kit** with part number **31N6-10210 31N610210**. The **travel motor seal kit**, such as for the **EX200-2/3**, is vital for preventing leaks in the drive system. For your undercarriage, we offer **track adjuster seal kits**, including the popular **PC200-5 PC200-6 PC200-7 PC200-8 TRACK ADJUSTER SEAL KIT** and the **ZAX200-3** kit with part number **9243267 9243267**. A properly sealed track adjuster is critical for maintaining track tension and preventing premature wear on components like the idler.

We also specialize in **control valve seal kits** like the **PC200-7 PC200-8 Excavator Control Valve Seal Kit 723-46-23100 7234623100**, which is necessary for repairing the main control valve. This valve, an intricate assembly of spools and passages, directs hydraulic fluid to the various cylinders and motors. The **center joint seal kit**, such as the **EX120-2/3/5 EX200-2/3/5** kit with part number **4231543 4231543**, is another critical component we supply. This seal is located in the center joint, a swivel joint that allows hydraulic lines to rotate freely as the upper body of the excavator swings. Without a functioning center joint seal, hydraulic oil could leak, leading to a loss of power.

Hydraulic Hammer & Breaker Parts

For hydraulic hammers and breakers, maintenance is key. We offer a full range of **hydraulic breaker seal kits**, including kits for **SOOSAN SB100** and **DMB2100** breakers. The **Montabert BRH-250/BRH-501/BRH-625** and **NPK GH-1** kits are also available. These kits are essential for maintaining the seals that protect the internal components of the breaker from dust and debris, while maintaining the high pressure required for operation.

Additionally, we supply crucial **diesel engine parts** like the **12V FLAMEOUT STOP SOLENOID 366-07197 36617197**, which is responsible for stopping the engine. We also have **Diesel Engine Fuel Injector Y729503-53100 Y72950353100** for **3D84, 3D88**, and other engines, as well as the **6CT Fuel Injector 3283160**. For our **Growshine International** customers, we ensure all parts are of the highest quality for long-lasting performance. We also offer **hydraulic pump seal kits** for Sauer Danfoss pumps, including the **PV20, PV21, PV22, PV23, PV24, PV25, PV26, PV27** series.

Common Machinery Maintenance & Troubleshooting

A common issue with excavators is a loss of power to the travel motor. For instance, on a **Caterpillar 320 excavator**, a loss of travel power can be caused by a faulty travel motor seal kit or a clogged hydraulic filter. To troubleshoot, first check the hydraulic fluid level and condition. If the fluid is okay, inspect the travel motor for external leaks. If leaks are present, replace the **Excavator Hydraulic motor seal kit EX200-2/3 travel motor seal kit** with a high-quality replacement. If there are no external leaks, the issue may be internal, such as a damaged piston or a worn-out swash plate, which would require a more extensive rebuild or replacement of the motor itself. For more complex problems, always consult a professional mechanic.

We are dedicated to providing parts that are not only affordable but also highly compatible with a wide range of machinery. Our team at **Growshine International** is committed to helping you find the right **heavy-duty truck parts** and **agricultural machinery components**, whether you're working on a **Komatsu PC200** or a **Caterpillar D65** dozer.
