11200.1. The type of PM inspection is determined and
controlled as follows:
Type "A" (01)At intervals of 40 working days.
It is performed on each scheduled PM due date
until a vehicle qualifies for a type "B" PM.
Type "B" (02)PMs are based on the equipment
manufacturers recommendations/
specifications for milage/hours usage required to
initiate a "B" (02) for fluid and filter change,
major adjustments or scheduled maintenance as
required. For example, a 5-ton dump truck
could undergo three or four "A" (01) PMs before
accumulating the required milage/hours for a
"B" (02) PM.
Type "C" (03)Annual safety inspection (ASI),
as per manufacturers recommendations/
specifications.
Deadline Vehicle
Deadline inspections are particularly critical to
ensure equipment does not deteriorate. Deadline
inspections are performed at each regularly scheduled
PM. An 01 level PM is accomplished on all deadline
CESE. The equipment is inspected to ensure the
following:
All openings are covered and weathertight.
All machined surfaces are preserved.
All disassembled components are tagged,
covered, and stored.
No cannibalization has taken place since the last
inspection (controlled parts interchange is not
approved as a normal procedure; however, the
maintenance supervisor only may authorize it to
meet operational commitments).
Parts removed from deadline equipment should
be replaced with non-serviceable items, and the
maintenance supervisor must ensure that
replacement parts are ordered "Not
Operationally Ready for Supply (NORS)." This
should be done using a priority applicable to
mission accomplishment.
All replacement parts, costs, and labor hours
related to the interchange should be charged
against the item of equipment on which the part
failed. When the replacement parts are received
1-6
and installed, only the labor involved should be
charged to the piece of equipment from which
the interchange part was taken.
Whenever possible, deadline inspections should
include cycling (checking components for proper
operation). For example, if a truck is deadlined for an
axle, you can still start the engine and ensure that it runs
properly. When cycling is accomplished, make sure
that all required preservation is accomplished.
Equipment is considered deadlined when it does not
perform as designed or when it is in need of parts that are
not on hand.
Accident
Accident safety inspections "12" ERO are initiated
on all CESE involved in a mishap, regardless of damage
and is commonly used for estimates. This inspection
ensures that a vehicle is in safe condition before being
released for operation Any repairs and parts required
must be charged against this Equipment Repair Order
(ERO). No preventive maintenance should be
performed. When preventive maintenance is required,
the type "12" ERO should be closed and another ERO
opened for the maintenance required.
PM RECORD CARDS
A Vehicle/Construction Equipment Preventive
Maintenance Record Card, NAVFAC 11240/6 (fig. 1-3)
must be accurately maintained for each item of assigned
equipment and attachments to assist the PM clerk in
preparing an ERO. PM record cards are maintained by
PM groups in a tickler file, and the following
information is to be recorded from the completed
preventive maintenance EROS:
Hydraulic filter change (indicated by HF/C)
Fuel filter change (indicated by FF/C)
Oil change or filter change (indicated by O/C or
F/C)
Cumulative mileage/hours
Date performed
Type of PM service performed
CESE with assigned attachments are identified on
the PM record card by a colored tab to ensure
attachments are given PM inspections with the assigned
equipment, and each attachment and attachment code
are listed on the back of the PM record card. The PM
