Description
Description
This O-ring (15x1.78) is a genuine OEM replacement part designed for the crankshaft assembly of small-displacement motocross bikes. It provides a critical seal within the engine's bottom end, preventing leaks and maintaining proper internal pressure. As an original equipment manufacturer part, it ensures a perfect fit and reliable performance under high-stress racing conditions.
This part is specifically designed for 50cc models from the KTM group. It is compatible with the 2024-2026 KTM 50 SX, 2024-2026 KTM 50 SX Factory Edition, 2024-2026 Husqvarna TC 50, and 2024-2026 GasGas MC 50. Whether you are maintaining a standard model or a Factory Edition, this O-ring is the correct specification for your engine's crankshaft.
Constructed from high-quality, oil-resistant rubber, this O-ring is built to withstand the extreme temperatures and chemical exposure found inside a two-stroke engine. Replacing worn seals during routine engine rebuilds is essential to prevent air leaks that can lead to lean running conditions and potential engine damage.
When installing this O-ring on the crankshaft, ensure the seating surface is clean and free of debris. It is recommended to lightly lubricate the seal with clean engine oil or assembly grease to prevent tearing during installation. Always refer to your service manual for specific torque settings and assembly sequences.
