3133053 is a special adjusting and sealing shim for transmission systems, clutches and hydraulic control mechanisms of construction machinery. It is mainly used for end clearance compensation, uniform pressure distribution, sealing leakage prevention and wear isolation between components. Made of high-precision sheet metal with precision machining, it has uniform thickness and flat end surface, which can effectively avoid direct friction of components, ensure stable assembly clearance, and perform reliably under vibration, oil pressure and high temperature conditions.
Technical Parameters
- Model: 3133053
- Type: Adjusting shim / Flat shim
- Material: High-quality carbon structural steel
- Surface Treatment: Anti-rust treatment, smooth and flat end surface
- Thickness Precision: Accurate size with good consistency
- Operating Temperature: -40℃~120℃
- Structure: Annular thin sheet with high concentricity of inner and outer circles, no burrs
- Features: Compression resistant, not easy to deform, wear-resistant, stable clearance compensation
Application Scenarios
Suitable for gearboxes, clutch assemblies, bearing seats, end covers, pistons and oil passage interfaces of construction machinery such as loaders, graders, rollers and forklifts. Used for axial clearance fine adjustment, end buffering, sealing leakage prevention and pressure distribution, adapting to heavy-duty, vibration, oil immersion and frequent reversing conditions.
Common Faults & Troubleshooting
- Increased clearance: Caused by long-term compression and wear of the shim. Replace 3133053 shim.
- Deformation and collapse: Caused by overload or impact leading to shim failure. Replace with a new shim and check assembly stress.
- Oil leakage: Caused by shim damage or uneven installation. Replace the shim and trim the sealing surface.
- Dislocation and curling: Caused by eccentric installation or embedded impurities. Clean and reinstall correctly.
