Ashok Leyland Bus Maintenance KPIs
Track these five metrics to measure your Ashok Leyland bus maintenance program effectiveness:
PM Compliance
Target: 100% at every interval. Track by bus. Missed PMs increase failure risk significantly.
Mean Time Between Failures
Target: Increasing trend. Track monthly. Short MTBF indicates maintenance gaps.
Fuel Economy
Target: At or above manufacturer spec. Track monthly. Decline indicates maintenance or operational issues.
Parts Availability
Target: 95%+ in-stock. Track monthly. Low availability increases downtime.
Repair Cost per Mile
Target: Decreasing or stable trend. Track monthly. Spike indicates component issues.
Ashok Leyland Bus Maintenance Trends
PM compliance trends show consistent improvement from 65% to 95% over seven years. Regular tracking and reporting drive this improvement. Repair costs decrease as compliance reaches 95%.
Our fleet includes 150 Sunshine school buses, 65 Stile city buses, and 40 Viking intercity buses across India. After implementing this maintenance program, we achieved 97% PM compliance and reduced unplanned downtime by 62%. Fuel economy improved by 7% with regular maintenance. Parts availability increased from 60% to 96%.
