DYNAPAC Repair Services India

Yes. Synchronics repairs the full Dynapac product range — vibratory compactors, asphalt rollers, tandem drums, and all associated control systems. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other tier-1 and tier-2 cities. All equipment is serviced and tested at our 18,000 sq ft facility in Vadodara, Gujarat, with same-day diagnostic reports and 7-10 day turnaround for most compactor repairs.

Immediate steps: (1) Stop compaction and shut down the machine. (2) Check hydraulic fluid level and color — dark oil signals bearing debris. (3) Verify engine RPM is normal (throttle not stuck). (4) Listen for eccentric motor humming — silence suggests motor stall. Call Synchronics immediately. We dispatch a field technician to on-site for emergency diagnostics, or accept expedited mobile delivery to Vadodara for bench testing. Most vibratory motor failures are repaired within 2-3 days, keeping your project timeline on track.

Visual signs: (1) Uneven asphalt surface with ruts forming on one side during compaction passes. (2) Audible out-of-phase drumming noise (irregular pulsing instead of smooth whine). (3) Operator reports difficulty steering straight or vibration felt through frame. Synchronics performs precision drum run-out measurement using laser alignment and cross-shaft bearing inspection. If drift exceeds 2mm, we replace couplings and reprogram PLC drum-phase sensor calibration per Dynapac maintenance manual to restore symmetric loading and surface finish.

CA-series oscillation relies on thermal-stable servo control. Under extended hot-asphalt operation (above 40 degrees ambient), power stage MOSFETs drift, frequency reference potentiometer drifts, or water vapor corrodes sensor connections. Frequency may shift from 48 Hz to 51-52 Hz, reducing asphalt density. Synchronics performs thermal chamber testing (0-60C soak) and recalibrates oscillation PID loops to lock frequency within ±1 Hz. We upgrade MOSFET gates with thermistor thermal compensation and reseal all sensor connectors with dielectric grease.

Synchronics recommends: (1) Daily — check hydraulic fluid level, inspect hose connections for leaks, verify parking brake engagement. (2) Weekly — change engine oil, test vibratory frequency output, confirm operator panel displays all parameters. (3) Monthly — flush cooling system, inspect bearing wear, clean hydraulic filters. (4) Quarterly — full system diagnostics including PLC memory check, solenoid valve response test, sensor calibration. We offer preventive maintenance contracts for Dynapac fleets operating in Indian construction companies, reducing unplanned downtime by 40-60% and extending equipment life to 15,000+ operating hours.

Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.

Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.

All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.

Yes. If we cannot repair your DYNAPAC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
