Re: gimble bearing

Are you sure you getting water? Extreme heat from a burning bearing will oxidize the chrome and tempered steel in the bearing filling it with a rust like residue. If your bearing is dry, yet, you see the rust this could be what is happening. The main reasons of failure of a gimbal bearing are lack of lubrication and engine missalignment. If you are properly greasing your gimbal bearing you should have your engine allignment checked immediately. GOOD LUCK!!!
