Thomas, if you want to download and install ANSYS Student 18.2 to have as well as AIM Student 18.2, you will be able to open the attached archive. I made a 2D axisymmetric model of your geometry. It has a Steady State Thermal model to calculate temperature, and a Static Structural model to calculate thermal expansion.
I just made up numbers for the Film coefficient for the surfaces in contact with water or air at 25 C and applied a temperature of 55 C to the bearings.
There is bonded contact between all the parts, so I don't know if that is a correct assumption, and if some parts can slide, then the stress result below would not be correct. Since all the materials are steel, there is not much stress due to thermal expansion, however, I left the base of this assembly free to expand in the X direction, which may not be a correct assumption either.
Let me know if you have questions.
