G15-81 EUI EUP Valve Core Grinding Repair Tool

The G15-81 EUI EUP Valve Core Grinding Tool is an essential maintenance device designed for diesel fuel injection specialists. As Electronic Unit Injectors (EUI) and Electronic Unit Pumps (EUP) age, the internal valve cores and valve seats often suffer from wear and microscopic damage due to high-pressure operation and fuel impurities. This wear leads to fuel return leakage, pressure drops, and poor engine performance.

This specialized grinding kit provides a precise solution to restore the sealing surfaces of the control valves. Engineered with high-precision abrasive guides, the G15-81 allows technicians to manually lap and grind the valve core contact surfaces to a factory-standard finish. By smoothing out scratches and restoring the geometric flatness of the valve, the tool effectively eliminates leaks and restores the proper holding pressure of the injector.

Suitable for a wide range of EUI and EUP models, this tool is a cost-effective alternative to replacing expensive injector assemblies. It is constructed from hardened steel materials to ensure long-term durability and consistent grinding accuracy in professional workshop environments.

• High Precision Restoration: Restores the perfect sealing capability of valve cores, fixing issues like hard starting and low power caused by internal leakage.

• Dual Application: Versatile design suitable for repairing both Electronic Unit Injectors (EUI) and Electronic Unit Pumps (EUP).

• Cost Efficiency: Allows workshops to repair worn injectors rather than scrapping them, significantly saving costs for customers.

• Durable Construction: Made from high-grade industrial steel to withstand frequent use and maintain grinding accuracy over time.

• Easy Operation: Designed for manual use, offering tactile feedback to ensure the technician does not over-grind the delicate valve surfaces.
