Rebuild or Exchange
Visually check for fluid leaks.Our recommendation to maintain the air compressor before it fails will be less costly to you than repairing the air compressor after failure.If you operate the engine until the air compressor fails, you could cause additional damage to your engine. For example: A failed air compressor could contaminate the engine oil with foriegn material since engine oil also lubricates the air compressor. The circulation of these contaminates through the engine lubricating system could damage the engine's main and connecting rod bearings.Maintenance Options
