Description

cutting holes 15 into the oil cavity 8. When the oil pressure drops during turbocharger run-down, the lubrication of the axle penetrates from chambers 13 through drilling 14, because some oil is accumulated in the chambers due to the location of the drain holes 15 above the horizontal plane, step n1, her through oci bushings.
