Bearings (Fi gure 49) are used throughou t the engine to reduce power loss, heat and noise resulting from friction . Because bearings are precision-made parts, they must be maintained by proper lubrication and maintenance. If a bearing is damaged, it should be replaced immediately. However, if installing a new bearing, care should be taken to prevent damage to the new bearing.
