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 body, chassis, and accessory items maintenance.
a.
Areas of the paving machine exposed to paving material buildup require cleaning prior to disassembly. Use
hammers, chisels, and scrapers to remove thickest sections of buildup. If available, use heater gun to soften deposits
adhering to components; remove softened buildup with putty knife. When heating paving material, keep second person
with fire extinguisher at hand and avoid overheating. If heater gun is not available, use solvent or fuel washdown system
to soften paving material.
b.
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.
c. Inspect all removed components for wear or damage. Replace damaged parts. Replace used lockwashers, self-
locking nuts, seals, and gaskets.
d. 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.
e. Clean painted surfaces thoroughly before repainting. Do not paint over rust or corrosion. Cover air breather ports
and hydraulic components. Do not paint bearings or other parts that require surface lubrication. Reference TM 43-0139
for equipment painting requirements.
f. Use only authorized replacement parts. Refer to TM 53895-373-24P, Repair Parts and Special Tools List
(RPSTL) for authorized replacement parts.
g. Torque values cited in the text apply to modified SAE Grade 8 fasteners at required clamping loads.
h. Observe all warnings and cautions. Wear protective clothing and equipment as specified. Observe the Safety and
Hazard Warnings provided in TACOM technical bulletin TB 43-0216.
