Turbo charger bearings

Replacement interval determined by type lube oil filtration between 5000-8000 hrs. thrust bearings are tappered land type. The wear of thrust bearing is measured by calculating the ratio of tappered to flat land
part. As thrust bearings are worn flat land increases compared to flat land. in turbine side flat to tapper ratio-1:1, while in compressor side 1:2. in journal bearing clearances is measured using a dial gauge

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
