Picture 1 shows the hurriedly made extractor I made to pull the cutlass bearing out. Even then after 50  plus years it was not going to come out without a fight, heat and brutality. Inserting the bearing was simple, place the newly made bearing in the freezer over night and drop it straight in to the centre.

It is important to ensure that the legend (marked on the reaction unit) is dead level as this is the start of the setup lines to decide the 20 thou gap. It is not easily seen in my pictures.
