Does your system have a preventive maintenance plan ?


PM is a schedule of planned maintenance activities aimed at the prevention of

mechanical breakdowns and failures.


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.


Useful Life Criteria

6-S, Minivan, 5 years, 100,000 miles 6-1MV, Modified minivan, 5 years, 100,000 miles 7-1MS, Modified van, 5 years, 100,000 miles 7-1MR, Modified van, 5 years, 100,000 miles 12-M, Modified van, 5 years, 100,000 miles 7-1B Bus, 6 years, 150,000 miles 8-2B Bus, 6 years, 150,000 miles 12-2B Bus, 6 years, 150,000 miles 16-2B Bus, 6 years, 150, 000 miles 16-2BHD Bus, 6 years, 150, 000 miles 12-B Bus, 6 years, 150,000 miles 24-B Bus, 6 years, 150,000 miles 24-BHD Bus, 6 years, 150,000 miles (See Attachment A)

PM plan is the foundation of an effective transit system maintenance program and

is required for all LADOTD transit systems.


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.)


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)


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


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


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


Warranties

All warranty information in vehicle packets upon pickup/READ, READ, READ

3 years/36,000 miles Chassis/Ford, Chevy, Dodge/Local dealer Modifications National Bus Sales (800) 282-7981 (Goshen or Elkhart

Coach, Braun Corp) Bus Group (866) 726-5142 (ElDorado, Transtech or Aerotech) Transportation South (800) 367-9463 (Startrans or Starcraft) Must have authorization before work is done DOTD contact & technical support information

(See Attachment H)


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
