GENERAL MAINTENANCE PROCEDURES.
All unit level maintenance shall be performed in
accordance with good and safe shop practices. Observe
the following general instructions and requirements when
performing exhaust system maintenance.
a. Thread locking compound is used with most
threaded fasteners. If a threaded fastener will not break
loose, heat threaded area of fastener from 500° to 600°F
(232° to 315C) with heater gun. If the special solvent
used to remove thread locking compound from screw
threads fails to remove buildup, discard fastener.
b. Inspect all removed components for obvious
wear or damage. Replace all worn, bent, broken, or
otherwise damaged parts.
c. Inspect all removed fasteners for thread
damage. If thread damage is found, replace fastener.
Replace flat washers if galled or bent. Use screw
extractor set (Item 15, Appendix E) to remove broken
studs or screws.
d. Use only authorized replacement parts. Refer
to TM 53895-373-24P, Repair Parts and Special Tools
List (RPSTL) for authorized replacement parts.
e. Torque values cited in the text apply to
modified SAE Grade 8 fasteners at required clamping
loads.
f. Observe all warnings and cautions. Wear
protective clothing and equipment as specified. Observe
the Safety and Hazard Warnings provided in TACOM
