7.1.2.2 Horizontal Precision and Parallelism of the Shafts
Position of the shafts is shown in Figure 7.5, Figure 7.6, and Figure 7.7.
- Check the horizontal specification with a level. The shafts should be horizontal within ±1/300.
- Check the parallelism with a scale. They should be within (length A − B) / L = ±1/300.
- Align the sprocket faces within tolerances shown in the table (Figure 7.7).
