Fail: Worn pads below minimum. Air leaks. Brake fluid contamination.
Cooling System
Pass: Coolant level proper. No leaks. Coolant analysis passes.
Fail: Low coolant level. Coolant leaks. Contaminated coolant.
Transmission
Pass: Fluid at proper level. No leaks. Smooth shifting operation.
Fail: Low fluid level. Transmission leaks. Harsh shifting.
Electrical System
Pass: All systems functional. No fault codes. Battery voltage normal.
Fail: Fault codes present. Battery issues. Electrical component failures.
Replacement Trigger
Replace major components at manufacturer-specified intervals. Replace brake components when worn. Replace batteries every 4-5 years. Document all service actions.
New Flyer Bus Maintenance KPIs
Track these five metrics to measure your New Flyer bus maintenance program effectiveness:
PM Compliance
Target: 100% at every interval. Track by bus. Missed PMs increase failure risk significantly.
Powertrain Health Index
Target: Monitor engine/EV/hydrogen performance. Track monthly for early issue detection.
Parts Availability Rate
Target: 95%+ in-stock. Track monthly. Low availability increases downtime.
Warranty Claim Success
Target: 90%+ claim approval rate. Proper documentation is essential for New Flyer warranty.
Repair Cost per Mile
Target: Decreasing or stable trend. Track monthly. Spike indicates component issues.
New Flyer 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%.
Powertrain Service Comparison
XD-40 Diesel Service
Standard diesel maintenance with engine oil, fuel filters, and DEF system service. Lower upfront complexity but ongoing fluid costs.
XE-40 EV Service
Battery health management, thermal system maintenance, and HV safety inspections. Lower ongoing costs but specialized training required.
XHE-40 Hydrogen Service
