Notes d'installation
Liste de contrôle de pré-installation:
1.Inspecter les composants:Vérifiez le numéro de pièce (082V02500-0710) and check for shipping damage.
2.Cylinder Honing: Ensure cylinder walls are honed to recommended roughness (Ra 0.4–0.6 μm) for proper ring seating.
3.Clearance Check: Measure piston-to-cylinder clearance (0.05–0.08 mm) and pin-to-rod clearance (0.015–0.025 mm).
4.Lubrification: Apply engine oil to piston pin, rings, and skirt before installation.
Étapes d'installation:
1.Ring Installation: Install compression and oil rings using proper ring expander tool, ensuring gaps are staggered.
2.Piston Orientation: Insert piston into cylinder with arrow mark toward front of engine.
3.Pin Installation: Connect piston to connecting rod using proper pin and circlips.
4.Spécifications de couple: Tighten connecting rod bolts to 120 ± 5 Nm + 90° angular turn.
Avertissements critiques:
Never reuse old pistons or circlips—always replace with new components.
Avoid hammering piston during installation—use proper tooling.
Verify ring end gap (0.25–0.40 mm for compression rings) to prevent seizure.
Post-installation:
Prime oil system before startup.
Run engine at idle for initial break-in (avoid high loads for first 500 km).
Monitor for unusual noises or smoke indicating installation issues
