a rotational axis;
a housing comprising a tubular portion, the tubular portion comprising:
a first distal end arranged on an engine side of the housing; and
a second distal end arranged on a transmission side of the housing;
a shaft extending through the tubular portion;
a first seal arranged to seal the shaft to the first distal end;
a first ball bearing disposed on the engine side adjacent to the first seal to position the shaft in the tubular portion;
a plain bearing arranged at the second distal end to position the shaft; and
