   If parts are not properly lubricated, they may start to make unusual noises or vibrations. This can be a sign of excessive friction and wear on critical components.
   
2. Overheating
   Overheating is a common sign of insufficient lubrication. If the machinery is running hotter than usual, it may be a result of friction caused by a lack of proper lubrication.
   
3. Excessive Wear or Damage
   Frequent breakdowns or excessive wear on parts such as bearings, gears, and seals could indicate that the lubrication system is not functioning properly.
