Evolution of Bus-Fleet Maintenance Practices 370191

BUS maintenance grew from haphazard patch-work repairs. Shortage of vehicles compelled stocking of service units. Standardization of equipment never has been accomplished. With competent mechanics not obtainable, they must be trained in bus work.
Card files and other records now keep track of performance of every unit and all major parts. Service expectancy cannot always be based on the past performance of the part. Complete inspection of all parts is periodically necessary.
Taxes make large numbers of standby buses economically impossible. High mileages are obtainable from modern buses. Rear engine locations are popular with the public.
Larger and better oil and air filters are needed; the same is true of oil coolers. Lubrication is not a problem. All worn parts now pass through the salvage department. Most units on modern coaches are of ample size and cause little trouble. Hypoids operate satisfactorily. Fuel economy is quite satisfactory considering weights and operating conditions.
