equipment necessary to perform maintenance operations described in this technical manual. TM 9-2350-287-24P is the
authority for requisitioning special tools and support equipment.

Fabricated tools are not available for issue.
The fabricated tools listed in Appendix E of this technical manual are of particular value to shops engaged in repairing a
number of identical components. The tools are listed in this manual to allow supporting maintenance shops to fabricate
them locally.
2-6. TROUBLESHOOTING PROCEDURES.

For ENGINE troubleshooting procedures, refer to TM 9-2815-202-34.
For TRANSMISSION troubleshooting procedures, refer to TM 9-2520-234-35.
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.
CAUTION
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
Pam 738-750.
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
them.
When assembling components and assemblies, replace damaged keys with new ones. If screws, washers, or nuts are
damaged, they must be replaced.
