- Clean the seal housing and the crankshaft surface thoroughly.
- Lightly lubricate the inner lip of the new seal with fresh engine oil.

- Reassemble the engine components in the reverse order of removal.
- Check for leaks after running the engine.
Troubleshooting & FAQ
How do I know if my crankshaft oil seal is failing?
The most common sign of a failing crankshaft oil seal is a noticeable oil leak from the front or rear of the engine where the crankshaft exits the block. You may see oil drips on the ground or residue around the flywheel or powerhead base.
Will this fit my specific Suzuki DT15 model?
This seal is compatible with the DT15C (1989–1997), DT15K-G-Y (1986–2000), and DT15K1-K4 (2001–2004) models. Always cross-reference your specific engine year and OEM part number with our compatibility table before ordering.
Is any special tool required for installation?
While not always mandatory, using a seal driver tool is highly recommended. It ensures the seal is pressed in evenly without damaging the delicate rubber lip or the outer metal case. A socket with a matching outer diameter can also work.
Can I reuse an old oil seal?
No. Oil seals are single-use components. Once removed, they are often stretched or damaged and will not provide a reliable seal if reinstalled. Always use a new seal during any major engine service.
Does the direction of the seal matter during installation?
Yes, absolutely. Most oil seals have a specific orientation. The side with the spring-loaded lip should typically face towards the oil (inside the engine) to ensure proper sealing pressure. Check your service manual for confirmation.
