The center housing supports the compressor and turbine wheel shaft in a pair of identical bearings that contain oil holes for directing oil to the bearing bores and shaft journals. Passages drilled in the center housing direct oil supplied by the engine from the inlet port to oil grooves machined in the bearing bores, that align with holes in the bearings.
