SMDC Clearance

6. SMDC and FCDC assemblies that do not pass inspection must be replaced. Repair of SMDC tubing is not permitted. 7. Proper clamp spacing (fig. 2-21) must be maintained to prevent damage to SMDCs due to vibration. Improper clamp spacing may result in failure of the SMDC. SMDC Clearance Correct clearances must be maintained between SMDCs, SMDC and adjacent structures, and tubing and operating mechanisms. In- sufficient clearances may result in damage to or failure of the SMDC. You must ensure SMDCs are installed with proper clearances as listed below: 1. Minimum required clearance between any supported section of SMDC and the adjacent structure is 1.00 inch. 2. Minimum required clearance between any straight, unsupported section of SMDC and an adjacent structure is 0.25 inch. 3. Minimum required clearance between any two parallel SMDCs is 0.10 inch. 4. Minimum required clearance between any two supported nonparallel SMDCs is 0.10 inch. 5. Minimum required clearance between any two unsupported nonparallel SMDCs is 0.10 inch. 6. Minimum required clearance between any supported section of SMDC and any operating mechanism is 1.00 inch. Figure 2-21.—SMDC clamp spacing. 2-28
