Message: <blockquote data-quote="Tazza" data-source="post: 3478" data-attributes="member: 82">As for the "Bobcat" section being viewed more often, this is just because people own more bobcat machines than any other that means more posts/views is all. In future, please keep the posts in the correct sections. Everyone will see your post, but most will not know much about that particular machine, thats why you don't have a mass of responces.Even though the filters are only 50 hrs old it may be worth changing them, even cut them open to see if there are any metal particles inside, if there are you know there is a problem. Does it happen when the machine is hot, cold or both? did it just start doing this? As you say going straight is quiet but turning is loud makes me think you have a blocked filter or using oil that is too thin. You can check with your dealer to see if there are any hidden suction line filters (if they will tell you) a blocked suction line filter will cause this exact problem.Its not really advisable to keep running your machine in this state if it is indeed cavitation from the pump starving of oil as it will cause damage. Cavetation will cause alot of heat and the imploding bubbles can actually cause pitting in pumps/lines/motors or cylinders. Avoid using the machine alot untill you get it fixed. See if you can run it for say 2-5 mins and see how hot your hydrostatic pump is, it should be no more than warm, you should be able to hold your hand on it.Its normal for them to make a small noise when moving, but nothing really loud. Usually at full throttle you can hardly hear it.</blockquote>
