My 2011 cat 312dl is squealing while it turns on the turn table. Not sure what to make of it. Would do it occasionally on a slope but now does it all the time. Checked oil level in the house it’s clean and correct. Greased the turntable. Not sure what it is. Thanks
Do you mean the oil level in the swing drive gearbox..? Have you pulled off the inspection cover at the front to check the condition of the grease in the swing gear cavity.? If it's badly contaminated you might have to remove it all and start fresh with new grease.
