Bearing-supported shaft assembly

An aircraft powerplant comprising:

• a shaft extending along an axis of the powerplant from a first shaft end to a second shaft end;
• a gearbox operatively connected to the first shaft end;
• a compressor rotor secured to the shaft at an axial location between the first shaft end and the second shaft end;
• a bearing assembly supporting the first shaft end, the bearing assembly including an inner race secured to the shaft and axially bound between the first shaft end and the compressor rotor, and an outer race radially outward of the inner race;
• a seal located radially outward of the shaft, the seal located axially between the bearing assembly and the second shaft end;
• a housing having a housing wall located between the bearing assembly and the seal, and an annular housing surface facing radially inwardly and surrounding the outer race;
• an annular bearing seal extending radially from the outer race to the annular housing surface;
• and
• a washer about the axis located axially between the bearing assembly and the seal relative to the axis, the washer extending axially from the outer race to the housing wall and radially from inward of the annular bearing seal to the annular housing surface.
