Installation Notes

Carefully remove the old seal using an appropriate seal puller, avoiding damage to the housing or shaft.
Thoroughly clean the shaft surface and the seal housing bore. Inspect both for any burrs, scratches, or corrosion that could compromise the new seal.
Lightly lubricate the inner lip of the new seal with clean engine oil and the outer diameter with a suitable sealant or oil.
Position the new seal squarely over the bore, ensuring the garter spring faces the direction of the fluid being sealed (typically inward).
Using a seal driver or a socket of the correct outer diameter, gently and evenly press the seal into the bore until it is fully seated and flush with the housing.
Re-install surrounding components and check for leaks after running the engine.

Troubleshooting & FAQ

How do I know if this oil seal will fit my Suzuki engine?

The best way to ensure compatibility is to verify your engine's model, horsepower, and year against the "Engine & Model Compatibility" table. Cross-referencing the OEM part number (09283-35043) from your service manual is also highly recommended.

What are the signs of a failing crankshaft seal?

Common symptoms of a worn or damaged crankshaft oil seal include visible oil leaks around the crankshaft area, an unexplained drop in oil level, or oil residue inside the engine cowling. A failed seal can also cause a vacuum leak, leading to poor engine idling or running issues.

Is this a single lip or double lip seal?

This product is available in single or double lip configurations, with the standard being a single lip. A double lip provides an additional dust/dirt seal but is not always required. Unless your application specifically calls for a double lip, the standard single lip version is the correct replacement.

How often should this seal be replaced?

Crankshaft oil seals do not have a fixed replacement interval. They should be inspected during any major engine service (like a rebuild or powerhead disassembly) and replaced if they show signs of drying, cracking, hardening, or leaking.

Do I need a special tool for installation?

Professional installation is recommended. A proper seal driver set is the ideal tool to ensure the seal is pressed in evenly without damaging the seal's lip or the engine housing. Using an improvised tool can lead to premature failure.
