Performance Parameters
Surface Hardness: HRC 42-48, Core Hardness: HB 200-240 mm, elastic modulus 206 GPa, fatigue life ≥10^6 cycles, flatness ≤0.03 mm, no sealing structure, suitable for system pressure ≤10 MPa.
Structure and Adaptability Characteristics:
* **Locking Plate Anti-Loosening:** One-piece stamped molding with elastic locking claws. After installation, it embeds into the tappet slot to prevent axial movement of the tappet during high-frequency reciprocating motion, suitable for the harsh operating conditions of the engine fuel pump tappet chamber.
* **Spring Steel Material:** 65Mn spring steel, quenched and tempered, possessing both high strength and elasticity. It can be repeatedly disassembled (≤5 times) while maintaining its locking performance, suitable for the vibration and temperature fluctuation environments of heavy-duty engines.
* **Precise Positioning:** The positioning hole and locking plate opening precisely match the tappet size, ensuring stable tappet movement trajectory, guaranteeing fuel injection timing accuracy, and avoiding power loss and increased fuel consumption caused by abnormal injection advance angle.
Compatible Engines and Application Scenarios
Engines: Heavy-duty diesel engines such as 3176C, 3196, 3306, 3406, 3406B, 3406C, and C-12.
Construction Machinery: Equipment compatible with 3406 series engines, such as Cat 777 mining trucks, 988 loaders, and D11 bulldozers.
Application Scenarios: Inside the fuel pump tappet chamber, used to fix the tappet assembly and limit the axial displacement of the tappet, suitable for stable operation under high engine speed (≤2200 rpm) and high injection pressure (≤180 MPa) conditions.
