3. Accept dents (see Figure 3) in the thin-wall section of the Body Tube, e.g., within 37 inches from the Top’s stacking lugs, only if the inner diameter is greater than or equal to 3.109 inches. Inspection can be accomplished by inserting a calibrated diameter inspection cylinder

(length: 6 inches min.) machined to an outside diameter of 3.109 ± 0.005 inches.

Figure 4).

4. Reject unit if the inner diameter of the Body

Tube’s thin-wall section is less than 3.109 inches. Inspection can be accomplished by inserting a calibrated diameter inspection cylinder (length: 6 inches min.) machined to an outside diameter of 3.109 ± 0.005 inches.
