⚙️ Features

Direct OEM Replacement: Perfectly matches CF Moto OEM part number 30499-03500 for precise fitment.
Standard Model 6307: Universal deep groove ball bearing widely used in engine and transmission applications.

✅ Importance of Bearing Replacement: Bearings are critical components that support rotating shafts and reduce friction. If a bearing wears or fails, it can cause shaft misalignment, increased noise, vibration, and eventual seizure, leading to severe engine damage. Common symptoms include: grinding noise, rough operation, shaft play, and overheating. During engine overhaul or when experiencing bearing-related symptoms, replace bearings with high-quality components.

⚠️ Installation Tips: Use proper bearing installation tools to press the bearing into place, avoiding impacts that could damage the bearing. Ensure the bearing bore and shaft are clean and free of burrs. Pack with appropriate grease if required.
