Notas de instalación
Lista de verificación previa a la instalación:
1.Inspect Components: Verificar número de pieza (082V04101-0539) and check for straightness (roll on flat surface) and stem finish.
2.Cleanliness: Ensure valve guide and seat are free of carbon deposits and debris.
3.Measurement: Check valve stem-to-guide clearance (0.02-0.05 mm) and valve face runout (max 0.03 mm).
Pasos de instalación:
1.Lubricación: Apply clean engine oil to valve stem before insertion.
2.Insertion: Gently insert valve into guide, avoiding force to prevent stem damage.
3.Spring Installation: Install valve spring, retainer, and locks using proper compressor tool.
4.Lash Adjustment: Set valve clearance to 0.25-0.30 mm (cold engine) using feeler gauges.
Advertencias críticas:
Never reuse old valves; replace in sets per cylinder.
Avoid lapping unless specified; some OEM valves are coated and require no lapping.
Verify valve seat concentricity (max 0.05 mm runout) before installation.
Post-instalación:
Run engine and listen for unusual valve train noises.
Re-check valve clearance after first 500 km of operation
