So the dozer has had this issue ever since i got it, the engine oil level mysteriously just went up up up by itself over time and the hydraulic oil level went down at the same time. This has to mean that the 2 oils were mixing somehow. Result is pretty obvious, the engine oil gets diluted over time thus engine oil pressure is lost and eventually engine damage may occur. In this video i will be checking both the hydraulic pumps, replacing the seals and also doing other minor fixes for the dozer.
