repairs shall be accomplished to ensure safe and
serviceable equipment. Intermediate maintenance
requires a higher degree of skill than organiza-
tional maintenance, a larger assortment of repair
parts, more precision tools, and more complex
testing equipment. Prior approval is required by
COMCBPAC, COMCBLANT, or CESO before
purchasing expensive parts or components for
any CESE requiring extensive repairs or numer-
ous assembly rebuilds. For further guidance
see COMCBPAC/COMCBLANTINST 11200.1
series, section 2, paragraph 3201.
The third level of maintenance is depot
maintenance. This is performed on equipment
that requires major overhaul or restoration to the
degree necessary to restore the unit to a like-new
condition. This level of maintenance is not
normally performed by field units, NMCBs,
ACBs, and the like. Depot maintenance is
performed by designated overhaul facilities, such
as construction equipment departments located
Port Hueneme, California,
Mississippi, and CBC Davisville,
The standard interval between preventive
maintenance service inspections for NCF CESE
is 40 working days. This interval is established
initially by grouping all assigned CESE into 40
separate PM groups. The CESE is distributed
evenly among the PM groups so that only the
minimum number of similar units is out of service
at any one time.
It is the responsibility of the maintenance
supervisor to determine whether the PM interval
for any unit of CESE should be reduced.
To maintain reliability, increased working tempo
demands increased preventive maintenance.
The maintenance supervisor may decrease the
interval by assigning specific CESE to more than
one PM group or reducing the total number of
PM groups. The maintenance supervisor is not
authorized to extend the standard interval between
PM service inspections beyond 40 working days.
To establish a deployment schedule of PM due
dates, the maintenance supervisor records the
working days of the month consecutively beside
the PM group numbers. See the sample schedule,
