Gas turbine engine with speed sensor

A gas turbine engine, comprising:

• a fan;
• a fan drive gear system coupled with the fan and a fan drive input shaft;
• a compressor section including a first compressor and a second compressor;
• a turbine section including:
• a first turbine coupled with a first shaft, and
• a second turbine coupled through a second shaft to the second compressor;
• a bearing assembly supporting the fan drive input shaft, the bearing assembly being located proximal to, and radially spaced from, a forward end of the first shaft, the bearing assembly including a speed sensor target that is rotatable with the forward end and that defines a rotation path, the bearing assembly including a radially outer bearing retainer, a radially outer bearing race retained in the radially outer bearing retainer, a radially inner bearing retainer, and a radially inner bearing race retained in the radially inner bearing retainer, the radially inner bearing retainer including a bracket section and a shank section connecting the bracket section to the fan drive input shaft and radially spacing at least a portion of the bearing assembly from the forward end;
• and
• a speed sensor probe situated proximal to the rotation path and operable to read the speed sensor target, the speed sensor target being located on the bracket section.
