(70) Subtract 2.00-in. (50.8 mm) from result in step (69) and write down answer. This is

measurement B.

(71) Subtract measurement B from measurement A, step (63), and write down answer.

(72) Subtract answer in step (71) from 0. 136-in. (3.45 mm). This answer is shim gap indicator.

(73) If shim gap indicator is 0.000 to 0.008 in. (0.00 to 0.20 mm), shim is not required. If gap is

0.009 to 0.028 in. (0.23 to 0.71 mm), use 0.010 in. (0,25 mm) shim. If gap is 0.029 to 0.048 in.

(0.74 to 1.22 mm), use 0.020 in. (0.51 mm) shim. If gap is 0.049 to 0.068 in. (1.25 to 1.73 mm),

use 0.030 in. (0.76 mm) shim. If gap is 0,069 to 0.088 in. (1.75 to 2.23 mm), use 0.040 in.

(1.02 mm) shim, and if gap is 0.089 to 0.108 in. (2.26 to 2.74 mm), use 0.050 in. (1.27 mm) shim.
