Common Bomag Road Roller Faults: Troubleshooting & Case Studies
Understanding critical faults in road roller machine parts prevents costly downtime. As a premier road roller parts factory, we analyze frequent Bomag roller failures and highlight how quality aftermarket parts ensure longevity.
Ⅰ. Mechanical Failures
1. Excessive Vibration
Causes:
- Damaged/misaligned bearings (key parts of road roller)
- Excessive bearing clearance
- Unbalanced tires or incorrect pressure
Solutions:
- Inspect/adjust bearings; replace faulty road roller spare parts.
- Balance tires; stabilize pressure.
2. Low Vibration Frequency
Causes:
- Faulty vibration shaft
- Low pump pressure
- Air leaks in oil lines
Solutions:
- Check shaft integrity.
- Increase pump pressure; seal leaks.
Ⅱ. Electrical Failures
1. Loss of Power
Causes:
- Motor failure
- Electrical shorts/power supply issues
Solutions:
- Test motor/wiring; replace damaged components.
2. Abnormal Vibration
Causes:
- Faulty vibration controller
- Damaged vibration motor
Solutions:
- Inspect controller/motor; secure connections.
Ⅲ. Startup Failure
1. Fuel System Checks
- Bleed air from diesel lines via hand pump.
- Replace clogged fuel filters (essential road roller spare parts).
2. Electrical System Inspection
- Charge/replace weak batteries (critical in winter).
- Test/replace starter solenoid.
3. Mechanical Components
- Verify crankshaft rotation; address starter/flywheel misalignment.
- Inspect valve timing synchronization.
Ⅳ. Case Studies: Aftermarket Parts Fix Critical Failures
Case 1: Pilot Pump Failure
Symptom: Pressure drop to 1.1MPa (vs. 3.14MPa standard).
Diagnosis: Aluminum debris in pilot filter indicated pump damage.
Solution: Replaced pilot pump (Bomag parts road roller-compatible) + adjusted relief valve.
Case 2: Rear Pump Variable Mechanism
Symptom: Slow left travel/boom/stick functions.
Diagnosis: Stuck regulating piston limiting pump displacement.
Solution: Disassembled mechanism; cleared debris; restored flow.
Case 3: Travel Deviation
Symptom: Consistent one-side drift.
Diagnosis: Swapped main pump lines; confirmed pump/variable mechanism fault.
Solution: Repaired with Dynapac road roller spare parts-equivalent components.
