2-7. REPAIR METHODS.
Complete disassembly is not always necessary to make a repair. Exercise good judgment to keep disassembly and
assembly to a minimum.
Never scribe marks on bearing surfaces. Damage to the bearing will result.
To be certain of correct positioning at assembly, mark gears on mating teeth with scribe marks, dye, indelible ink, or paint.
Avoid the use of chalk and crayon because they smudge and are easily wiped off.
During assembly, subassemblies should be assembled first, combined into major components if possible, and then installed
to form a complete component.
Records to provide repair and replacement data and statistics should be carefully prepared and maintained according to DA
Replacement of Parts
Unserviceable or unrepairable assemblies will be broken down into items of issue, and serviceable parts will be returned to
stock. Parts or assemblies that cannot be repaired or reconditioned will be salvaged, and new parts will be used to replace
When assembling components and assemblies, replace damaged keys with new ones. If screws, washers, or nuts are
damaged, they must be replaced.
