OIL SEAL, 40X55X7 (N

Engine Oil Seal (40×55×7) — Tight Leak Protection ?

This precision oil seal is a small but critical barrier that keeps engine oil where it belongs and blocks dust, water, and grit from entering rotating assemblies. It’s needed wherever a shaft passes through an engine or gearbox housing—oil pressure and spinning parts will quickly find any weak spot.

How It Works ⚙️

The seal uses a flexible rubber lip that rides on the rotating shaft, supported by a reinforced body that presses tightly into the housing. A thin oil film forms at the lip edge to reduce friction while maintaining a leak-proof contact. Correct sizing (40×55×7) ensures proper press-fit and lip tension.

If It Fails ?

A worn or hardened seal can cause oil seepage or active leaks, leading to low oil level, burning-oil smell, smoke, messy underbody, and possible clutch/drive belt contamination. Long-term driving with a leak risks poor lubrication, overheating, and expensive internal wear.

Common Signs

• Oil wetness around housing/shaft area
• Drips after parking
• Oil smell on hot surfaces
• Unexplained oil level drop
