Blue Bird Bus Repair Service

School routes and charter schedules can’t slip. We keep Blue Bird fleets dependable with brand-informed diagnostics, spec-correct parts/fluids, and clear documentation—so children ride safe and your buses leave the yard on time.

Diagnostics & common repairs

We follow a test-first workflow to confirm root cause before parts go on:

  • Aftertreatment & emissions: frequent regens, DPF/DEF/NOx/EGR faults, dosing and sensor wiring
  • Power & drivability: hard starts, low power, smoke, fuel restriction/aeration, turbo/VGT control
  • Cooling & HVAC: overheating on grades, heater performance, electronic fan drive, A/C leaks & controls
  • Electrical & body multiplex: lighting, dash warnings, door & wheelchair-lift circuits, camera/GPS/PA power
  • Brake & chassis: air leaks, ABS sensors/valves, air dryer service, steer/suspension wear, wheel-end noise
  • Charging/starting: batteries, alternators, parasitic draw, grounds/voltage drop

Diesel platforms we service

Blue Bird Vision and All American FE/RE in diesel configurations powered by Cummins B6.7/ISB and legacy C7/ISC-class diesels. Engine and chassis work are coordinated under one RO for a complete fix.

Major repairs

  • Engine (diesel): head gaskets, injector & high-pressure fuel systems, turbo/VGT actuators, EGR coolers/valves, oil/coolant leaks, in-frame repairs, and approved reman long-block replacements when downtime or economics favor a swap.
  • Transmission (Allison 2000/3000): diagnostics, fluid & filter services, valve body/solenoids, clutch health, relearns, and reman replacements with road-test validation.

Preventive maintenance & fleet programs

Route duty, idle time, and climate drive PM—so we tailor intervals by miles/hours/calendar:

  • Oil, fuel, and air filtration; coolant test/exchange; belt/hose; CAC & cooling-stack cleaning
  • Axle/Allison fluids to spec; air dryer cartridges; brake lining/rotor/drum measurements
  • Steering/suspension, torque checks, wheel bearings, and tire inspections/PSI
  • Battery/load tests and DVIR follow-ups
  • DPF cleaning/ash service by hours and backpressure trend
    Fleet support includes priority scheduling, PM calendars, consolidated invoicing, and VIN-level history.

Compliance & safety

BIT/DOT and California CHP terminal inspection readiness: lighting, brakes, steering/suspension, leaks, tires, and documentation. We correct deficiencies quickly and provide records for audits and board reports.
