The Complete Guide to Chain

7. Manipulation of Chains

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. 1.Check the horizontal specification with a level. The shafts should be horizontal within ±1/300. 2. Check the parallelism with a scale. They should be within (length A – B) / L = ±1/300. 3. Align the sprocket faces within tolerances shown in the table (Figure 7.7).
