TM 5-3825-220-13&P 6-4.9  Grooved Coupling Clamps - Cont'd 1. If a coupling is leaking and the clamp is fully closed, it should be opened and inspected.  Generally, if the clamp is not damaged, an adjustment to or replacement of the gasket will correct the problem. 2. If the clamp is damaged or worn and thus not functioning, it should be replaced. 3. The damaged or worn clamp can be repaired in a qualified and properly equipped shop as follows: a) If a key (the projection that fits into the grooves) has a burr that prevents the clamp from closing in the groove, it may be filed or ground off. b) If the pins are worn, they should be replaced. c) If the handle is bent or distorted, it should be replaced. d) If  a  key  is  broken  or  the  clamp  body  is  distorted,  the  clamp  should  be  passed  thru  established maintenance channels for disposition. 6-4.10  Hoseline Swivels a. Swivels  are  provided  with  the  transfer  hoselines  to  minimize  twisting  action  on  the  hose.    Information  on  the swivels is found on Fig.  2-31 and 6-9.  The swivels are not designed to rotate easily, particularly in the unpressurized condition.  They must, however, rotate if hose twisting is to be avoided. b. If the swivels are not turning, they require corrective maintenance.  The swivel is dissassembled as shown in Fig. 6-9.  Possible causes and corrective actions are as follows: 1. Dry bearing- Clean, inspect, and repack with light grease. 2. Interference and galling - Inspect and note any galled surfaces.  Dress with emery cloth, clean, lubricate and reassemble. 3. Missing or worn ball bearings - Inspect, replace all ball bearings, lubricate and reassemble. 4. Swivel leaking - Inspect and replace O-rings. 5. Leakage at couplings - Inspect and handle as in para.  6-4.9. 6-4.11  Aluminum Pipe a. Six (6) inch aluminum pipe is Government furnished.  The pipe is described in para.  2-5.2 and on Fig.  2-37A. For the convenience of maintenance, appropriate information is shown on Fig.  6-14. b. Recommended corrective maintenance actions are: 6-18
