TM 9-2350-358-BD 6-5. SHROUDS, AIR COOLING DAMAGED General Information: Shrouds are used to direct the cooling air over the hot engine. Bent or torn shrouds will upset the flow of air and cause hotspots to occur which can cause internal engine failures. Torn shrouds can be bent back into shape and patched with sheet metal, epoxy kits or tape to restore the proper air flow. At a minimum, they must be bent to prevent contact with moving components. If the existing shrouds cannot be repaired, new shrouds must be fabricated from sheet metal. Option 1: Bend shrouds back into their original position or replace missing portions of shrouds with sheet metal. Limitations: None Personnel/Time Required: • 1 soldier • 3.0 hours Materials/Tools: • Epoxy, adhesive (item 2, Appendix C) • Sheet metal (scavenge from available source) References: TM 9-2350-314-20-1-1 Procedural Steps: 1. Gain access to shrouds by removing engine access cover. 2. Bend shrouds back to their original positions. 6-4
