G14-43 Denso valve stem grinding tool

The G14-43 Denso Valve Stem Grinding Tool is a precision-engineered solution for repairing worn or damaged valve rods in common rail injectors. In high-pressure diesel systems, even minor surface irregularities on the valve stem can lead to friction, sticking, or fuel leakage.

This kit provides a manual, high-precision method to resurface the valve stem, ensuring it slides perfectly within the valve body. By using the specialized circular grinding jigs and professional-grade polishing compounds, technicians can restore components to factory-standard smoothness.

Kit Components:

• Precision Grinding Jigs: Multiple sizes of circular guides designed to hold and align the valve stem during the grinding process.

• Adjustment Tool: A T-handle hex key for securing and fine-tuning the grinding jigs.

• Diamond Polishing Pastes: Multi-stage syringes (e.g., 3.5 and 7 micron) for progressive smoothing from coarse repair to mirror finish.

• Compact Storage Case: Lightweight, transparent organized case for easy part identification and portability.
