EMD Product Lines We Repair
Our engineers are trained on the full EMD product range. Below are the major product families we service.
EMD 645 Series Diesel Engines
Heavy-duty medium-speed engines used in gensets, marine propulsion, and industrial power generation. Common repairs include fuel injection control failures, turbocharger electronic boost pressure sensors, and engine management system (EMS) module failures.
EMD 710 Series Diesel Engines
High-performance large-bore engines for prime power generation and continuous duty applications. Typical issues include electronic fuel metering unit (EFMU) faults, engine governor control failures, and CAN-bus communication errors in modern variants.
EMD Power Generation Control Systems
Integrated electronics for synchronization, load sharing, and voltage regulation in multi-unit genset installations. Repair scope includes exciter modules, automatic voltage regulators (AVR), and paralleling switchgear control units.
EMD Fuel System Electronics
Fuel injection control modules (FICM), fuel pump electronic units, and pressure limiting valves with integral solenoids. Common failures: coil burnout, internal pressure regulator drift, and electrical connector corrosion in high-vibration environments.
EMD Turbocharger Boost Control
Electronic boost pressure sensors, wastegate actuator solenoids, and turbo speed governors. Typical faults include sensor calibration drift, solenoid valve stiction, and wiring harness failures due to engine bay heat cycling.
EMD Engine Monitoring & Diagnostic Systems
Real-time engine parameter monitoring, fault code logging, and predictive maintenance electronics. Repairs address CAN-bus module failures, sensor signal conditioning PCBs, and firmware corruption in embedded controllers.

Common EMD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EMD equipment arriving at our workshop.
- ✓Fuel Injection Control Module (FICM) failures — EMD FICM units experience coil burnout and internal solenoid plunger seizure due to fuel contamination, thermal stress from engine block proximity, and exposure to vibration-induced micro-fractures. Common in older 645 and 710 series engines running in dusty Indian industrial environments without adequate fuel filtration.
- ✓Electronic Engine Governor (EEG) control system drift — EMD governor modules experience analog input signal drift caused by connector corrosion, PCB solder joint degradation from thermal cycling, and instrumentation potentiometer wear. Units running >50,000 hours show load-sharing imbalance in parallel genset installations, manifesting as hunting or speed instability.
- ✓Turbocharger Electronic Boost Control (EBC) sensor failures — EMD boost pressure sensors experience zero-drift and span degradation due to thermal shock cycling (engine cold start to full load), salt-air corrosion in coastal/marine genset installations, and moisture ingress through damaged sensor connectors. Affects fuel economy and emission compliance tuning.
- ✓CAN-bus communication module timeouts and node isolation — Modern EMD 710K/M engines with networked electronics experience CAN termination resistor failures, transceiver IC degradation, and wiring shield discontinuity in long cable runs between engine ECU, genset AVR, and external monitoring systems. Common in retrofit installations where cabling was not properly rated for EMD CAN noise immunity.
- ✓Automatic Voltage Regulator (AVR) exciter module oscillation and overvoltage shutdowns — EMD genset AVR modules oscillate or shut down under transient load changes due to feedback compensation capacitor aging, power thyristor gate drive circuit failures, and improper tuning in field-modified installations. Output voltage swings ±15% instead of specified ±2%, tripping downstream load protection relays.
- ✓Fuel pump electronic control unit (FPU) pressure relief malfunction — EMD FPU solenoid-operated pressure relief valves experience stiction and erratic cracking pressures due to fuel varnish accumulation (poor fuel storage in Indian facilities), solenoid plunger corrosion, and internal spring relaxation. Results in fuel rail over-pressure, leaking injectors, and unburnt hydrocarbon emissions.

Frequently Asked Questions — EMD Repairs
Do you repair EMD equipment anywhere in India?+
Yes. Synchronics repairs the full EMD diesel engine electronics and power generation control range — FICM units, turbo boost controllers, electronic governors, AVR modules, and CAN-bus systems. We offer PAN India door-to-door pickup service from Mumbai, Delhi, Pune, Ahmedabad, Chennai, Hyderabad, Bengaluru, and all other major industrial cities. All repairs are completed at our Vadodara, Gujarat facility with factory-standard turnaround times.
What EMD fuel injection control failures can you repair in India?+
Synchronics specializes in EMD FICM (Fuel Injection Control Module) repairs for 645, 710, and 8V-series engines. We handle coil burnout, internal solenoid stiction, connector corrosion, and complete module recalibration. Our bench testing simulates Indian fuel quality variability, and we replace components with EMD-certified equivalents. Most FICM repairs return to 100% factory specification within 8 business days.
Can you repair EMD genset excitation and AVR systems for parallel operation?+
Yes. Synchronics repairs EMD automatic voltage regulator (AVR) and exciter modules used in multi-unit parallel diesel genset installations across Indian power plants, refineries, and industrial facilities. We recalibrate voltage feedback networks, replace aging capacitors, test thyristor gate drive circuits, and validate load-share stability on our three-unit test genset rig. Critical for maintaining grid-quality voltage in Indian manufacturing facilities.
How long does EMD diesel engine control system repair typically take?+
Standard EMD electronics repairs (governor modules, boost sensors, FPU units) are completed within 5-8 business days. Complex remanufacturing of FICM or AVR modules requiring component-level rework takes 8-12 business days. Rush turnaround available for critical power generation downtime — 48-hour express service for immediate priority repairs. Synchronics maintains stock of common EMD replacement modules for emergency substitution while your original unit is repaired.
Do you repair older EMD 645 series engines and newer 710K/M systems?+
Absolutely. Synchronics repairs both legacy EMD 645-series engines (analog governor and fuel control electronics) and modern 710K/M platforms (CAN-bus integrated controls). We stock replacement harnesses, connectors, and PCB assemblies for both generations. Many Indian industrial facilities run mixed-vintage genset fleets, and we service them side-by-side. Our engineers are certified on the full EMD product lineage from mechanical governors through advanced networked ECU systems.
How do I send my EMD unit for repair?+
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.
What is the cost of repairing a EMD drive or PLC?+
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.
What warranty do you provide on EMD repairs?+
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.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your EMD 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.
