Had the T190 under load with the bucket up, belt started to squeal, and then I heard what sounded like metal on metal screeching. Shut the machine down, hydraulic oil was 2 quarts low. Took the belt off along with the tensioner which both seemed to be in decent shape. Went to spin the pulley to the hydraulic pump and can definitely hear metal on metal. I'm hoping it's something as simple as a bearings replacement. Anyone experience anything like this? Thanks in advance
