Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Hydraulic breaker seal kits play a critical role in preventing oil leakage, maintaining internal pressure, and safeguarding hydraulic components from contamination and wear. For Caterpillar breakers, which operate under intense impact force and repeated high-pressure cycles, a high-quality sealing system is vital.
Key features of our Caterpillar breaker seal kits include:
- High Pressure Resistance: Withstands severe hydraulic shocks and pressure fluctuations.
- Impact-Grade Durability: Built to absorb vibration and mechanical stress typical in hammer operations.
- Temperature Tolerance: Performs reliably under extreme cold or heat.
- Leak-Free Operation: Enhances operational safety and efficiency with superior oil retention.
- Model Precision: Designed according to OEM dimensions to ensure perfect fit and seal integrity.
Structure Reference
Although the included schematic diagram may not label seal positions directly, it clearly illustrates the internal layout of the Caterpillar hydraulic breaker, helping operators locate cylinder, piston, buffer, and valve areas where seals are installed.
Note: For accurate identification of seal placement, refer to the model-specific exploded view or service manual during installation.
Installation Methods
Two common techniques are recommended based on breaker size and workshop equipment:
Method 1: Pin-Guided Press-Fit Installation
Use the dedicated mounting pin to align and guide the seals.
Apply a small amount of hydraulic oil for easier press-fit without damage.
Method 2: Tool-Assisted Professional Assembly
Use a ballast tool, locating cone sleeve, and auxiliary pressure plate.
This method ensures the seals are evenly loaded and prevents distortion during installation, especially on larger bore diameters.
