shop with PM group 10, it again has been used more than the recommended miles.
The Maintenance Supervisor should reduce the interval again. This would be done by
also adding the taxi to PM groups 20 and 40.
NOTE: The dispatcher should notify the PM Clerk/Maintenance Supervisor if
equipment is accumulating miles/hours quickly. As a result, the schedule
can be adjusted as required, rather than waiting for equipment to exceed
standards.
Preventive Maintenance Due Date Schedule. A Preventive Maintenance
Due D”a,, Schedule (Table 4-2-l) shall be established annually by the PM Clerk
because the schedules are based on the workdays in each calendar year. An NMCB
PM schedule is set up using Operations (S3) Workday/Deployment schedule. The
workdays on the schedule must correspond to the unit’s actual workdays; for example,
if you work a 6-day week, enter 6 days and omit holidays. The PM groups are
numbered vertically down the first column. Table 4-2-l depicts the standard 40 PM
group concept. The dates of workdays in January are then listed consecutively in the
January column. After January’s last workday is entered, start February’s workdays in
the February column. At completion, the schedule shows each workday that each PM
group is due for inspection. For example, Table 4-2-l shows that PM group 5 is due on
January 25, March 25, May 20, July 17, September 12, and November 7.
d. Preventive Maintenance Record Cards. A Vehicle/Construction
Equipment Preventive Maintenance Record Card, NAVFAC 11240/6 (Figure 4-2-l)
shall be accurately maintained for each item of assigned equipment. PM record cards
contain the vehicle’s preventive maintenance history in chronological order and
necessary information to assist the PM Clerk to prepare Equipment Repair Orders
(ERO). PM cards shall be maintained in PM group sequence in a separate file.
Equipment assigned to more than one PM group shall have dummy PM record cards
filed in the extra PM group(s). The PM Clerk shall record the following information on
the PM record card from the completed preventive maintenance EROS: type of PM
service performed, date it was performed, cumulative miles/hours. Engine oil changes
or filter changes shall be indicated by entering “O/C” or “F/C.” PM record cards shall be
returned to the Equipment History Jacket when the vehicle is transferred.
NOTE: CESE Attachments. The PM record cards on CESE that have
m Attachments are marked with a red tag to alert the PM Clerk that
Attachments are listed on the back and require servicing.
e. Preventive Maintenance Inspection Depth. The Preventive maintenance
- scheduling explained in paragraph 4-2.3.~ describes only PM frequencies; it does not
determine the extent of the PM inspection. Preventive maintenance and services
required shall be determined by an inspector, based on the manufacturer’s
recommendations and specifications.
