In section I we showed how to post-finish the (3) turbine case components. In this section we will show how to fit and assemble the complete shaft unit. The way in which this turbine is designed, there are only three semi-critical fits:

1. bearing to case spring depth
2. overall shaft spring depth
3. hot rotor to case clearance

In this section we'll cover (a) & (b) -- subject (c) will be covered in the next section of this manual.

We'll start out by identifying the shaft assembly components.
