3255773 is a special sealing and adjusting shim for transmission, clutch and hydraulic oil circuit systems of construction machinery. It is mainly used for end face sealing, clearance compensation, pressure distribution and wear isolation of components. Made of high-precision sheet metal with precision machining, it has uniform thickness and flat end surface, which can effectively prevent oil leakage and stably control assembly clearance, maintaining stable performance under vibration, oil pressure impact and oil immersion conditions.
Technical Parameters
- Model: 3255773
- Type: Sealing and 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, reliable sealing, stable clearance compensation
Application Scenarios
Suitable for transmission housings, clutch assemblies, bearing seats, end covers, oil passage interfaces and piston end faces of loaders, graders, rollers, forklifts and other construction machinery. Used for axial clearance fine adjustment, end buffering, sealing leakage prevention and uniform 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 3255773 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 the mounting surface before reinstalling correctly.
