2. PREVENTIVE MAINTENANCE
Does your system have a preventive
maintenance plan ?

3. PREVENTIVE MAINTENANCE
PM is a schedule of planned maintenance
activities aimed at the prevention of
mechanical breakdowns and failures.

4. PREVENTIVE MAINTENANCE
The primary goal of preventive maintenance
is to prevent the failure of equipment
before it actually occurs, ensuring that the
vehicles are safe to operate and
maximizing the vehicle’s useful life.

7. PREVENTIVE MAINTENANCE
PM plan is the foundation of an effective
transit system maintenance program and
is required for all LADOTD transit systems.

8. PREVENTIVE MAINTENANCE
The plan should describe how your agency
handles the following PM activities.
 Making preventive maintenance arrangements
 Adhering to a preventative maintenance schedule
 Conducting daily vehicle inspections
 Completing corresponding inspection checklist & follow
up on deficiencies
 Keeping a comprehensive maintenance record on file for
each vehicle/Documentation (checklists, reports,
receipts, etc.)

9. PREVENTIVE MAINTENANCE
Making Preventive Maintenance Arrangements
 PM plan should describe how you maintain the fleet and
equipment
 Maintenance department or private garage
 Who is in charge of scheduling vehicles for PM work?
 How is information conveyed?
 Who is responsible that PM schedules are followed?
 How are PM Intervals determined?
 See Attachment C (Maintenance Communication)

10. PREVENTIVE MAINTENANCE
Adhering to a preventative maintenance schedule
 Equipment manufacturer recommendations/Basic roadmap
 Mileage intervals/Manufacturer guidelines
 Seasonal variations/Fall, Winter, Spring, and Summer
 Environmental conditions/Dusty roads, stop and go driving
 Vehicle Cleanliness/ Establish a regular program for washing &
cleaning, road salt or brine will accelerate rusting. Dust from roads
causes poor driving conditions, passengers are not comfortable in a
dirty vehicle.
 See Attachment D (Preventive Maintenance Table) and Attachment
E (Preventative Maintenance Checklist) Page P-2, Red
Administration Handbook

11. PREVENTIVE MAINTENANCE
Conducting Daily Vehicle Inspections
 Daily pre-trip inspection sheet (required on all vehicles)
 Critical to success of the PM plan/Minor problems-corrected
 Drivers trained how to conduct inspections
 Properly complete form/all defects accurately noted
 Form should have all areas that driver is to check
 Space provided to document any problems
 Information should be the base for the PM program and forwarded
to maintenance department or repair shop when defects found
 See Attachment F (Daily driver pre-trip inspection) Page P-3, Red
Administration Handbook

12. PREVENTIVE MAINTENANCE
Conducting Daily Vehicle Inspections/continued
 Mechanics should perform thorough inspections when in
the shop
 Mechanics certifications/Automotive service excellence
 Mechanic inspection sheet (See Attachment G and G1)
 PM inspections/Certain mileage intervals

Documentation
 Maintenance records are required to be kept on file for each vehicle
 Records should include specific details when maintenance was performed,
whether preventive or unscheduled
 Pertinent information/mileage, dates, description of repair, cost, who
performed work
 Agencies are encouraged to develop spread sheets to help document oil
changes, tire rotations, inspections, etc. (See Attachments I thru L)
 Monthly maintenance reports are required on every active LADOTD public
transportation vehicle until its has reached its useful life. Report form is
required by the 15th day of the following month for the previous month.
 Monthly Maintenance/Expense Record (See Attachment O), Page R-14,
Red Administration Handbook
