Crankshaft Shaft Seal Ring 40x55x6 for KTM/Husqvarna 250/350 - 0760405561

This genuine OEM crankshaft shaft seal ring is a critical component for maintaining the integrity of your engine's lubrication system. Measuring 40x55x6 mm, it is specifically designed to provide a high-performance seal around the crankshaft, preventing oil leaks and protecting internal components from dust and debris.

This seal is compatible with an extensive range of 250cc and 350cc 4-stroke motorcycles. It fits KTM 250 and 350 SX-F, XC-F, and EXC-F models from 2015 to 2026, Husqvarna FC, FE, and FX 250/350 models from 2016 to 2026, and GasGas MC, EC, and EX 250F/350F models from 2021 to 2026. It is also used in the KTM Freeride 250 F and RC4 R racing models.

Constructed from high-quality Viton material, this seal offers exceptional resistance to heat and engine chemicals, ensuring a long service life even under racing conditions. Its precise fitment helps maintain consistent crankcase pressure, which is vital for the smooth operation of high-revving modern four-stroke engines.

During installation, it is recommended to lightly lubricate the seal lip with engine oil and use a proper seal driver to ensure it is seated squarely. Replacing a worn seal promptly can prevent more significant engine damage caused by oil loss or contamination.
