1. The inspection for “good condition” is usually an external visual inspection to determine whether or not the unit is damaged beyond safe or serviceable limits. The term “good condition” is explained further by the following: not bent or twisted, not chafed or burned, not broken or cracked, not bare or frayed, not dented or collapsed, not torn or cut.
2. The inspection of a unit to see that it is “correctly assembled” is usually an external visual inspection to see whether or not it is in its normal assembled position in the vehicle.
3. The inspection of a unit to determine if it is “secure” is usually an external visual examination, a hand‐feel, or a pry‐bar check for looseness; such an inspection should include any brackets, lock washers, lock nuts, locking wires, or cotter pins used in assembly.
4. “Excessively worn” will be understood to mean worn, close to or beyond serviceable limits, and likely to result in a failure if not replaced before the next scheduled inspection.
(d) Special Services. These are indicated by repeating the item numbers in the columns which show the interval at which the services are to be performed, and show that the parts, or assemblies, are to receive certain mandatory services. For example, an item number in one or both columns opposite a Tighten procedure, means that the actual tightening of the object must be performed. The special services include:
1. Adjust. Make all necessary adjustments in accordance with the pertinent section of the vehicle operator’s manual, special bulletins, or other current directives.
2. Clean. Clean units of the vehicle with dry‐cleaning solvent to remove excess lubricant, dirt, and other foreign material. After the parts are cleaned, rinse them in clean dry‐cleaning solvent, and dry them thoroughly. Take care to keep the parts clean until reassembled, and be certain to keep dry‐cleaning solvent away from rubber or other material which it will damage. Clean the protective grease coating from new parts, since this material is not a good lubricant.
3. Special lubrication. This applies both to lubrication operations that do not appear on the vehicle Lubrication Guide, and to items that do appear on such guides, but should be performed in connection with the maintenance operations, if parts have to be disassembled for inspection or service.
4. Serve. This usually consists of performing special operations, such as replenishing battery water, and draining and refilling units with oil.
