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 fuel system maintenance.
a.
All areas of the paving machine exposed to
paving material require wash down prior to maintenance.
Use spray wash down equipment per TM 5389537310.
Use hammers, chisels, and scrapers to remove paving
material buildup deposits.
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 6000F
(2320 to 315°C) with heater gun. If the special solvent
used to remove thread locking compound from screw
threads fails to remove buildup, discard fastener.
c. When removing tie wraps from hoses and wiring,
note or mark locations and anchor points. The proper
location and installation of tie wraps will prevent undue
chafing of hoses and wiring.
d. Always tag mating connectors and fittings before
disconnecting. Tagging of mating connectors and fittings
will ease reassembly and reduce assembly errors.
e. Inspect all removed components for obvious
wear or damage. Replace all worn, bent, broken, or
otherwise damaged parts.
f. Inspect all removed components for wear or
damage. Replace damaged parts. Replace used
lockwashers, self locking nuts, preformed packings,
seals, and gaskets.
g. 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.
h. Clean painted surfaces thoroughly before
repainting. Do not paint over rust or corrosion.
