HEENAN DRIVES LTD Product Lines We Repair
Our engineers are trained on the full HEENAN DRIVES LTD product range. Below are the major product families we service.
Heenan Compact Gearboxes
Heavy-duty reduction gearboxes for sugar mills and cement kilns. Common faults include bearing wear, gear tooth scoring, and seal leakage causing oil contamination and loss of torque transmission efficiency.
Heenan Industrial Drive Controllers
Electromechanical and electronic controllers for managing drive torque and speed in industrial transmission lines. Failures include capacitor degradation, relay contact wear, and control board corrosion in humid mill environments.
Heenan Shaft Coupling Systems
Flexible and rigid couplings designed for misalignment compensation in heavy rotating equipment. Common issues are bushing deterioration, bolt loosening, and radial/axial runout accumulation causing vibration and premature bearing failure.
Heenan Brake and Load-Hold Systems
Mechanical brake assemblies and electromagnetic load-holding devices for vertical and inclined conveyor systems. Typical faults include brake pad glazing, solenoid coil failure, and spring fatigue leading to uncontrolled load descent.
Heenan Power Transmission Gears
Precision-cut spur, helical, and bevel gears for sugar mill crushers and cement kiln drives. Repair focuses on gear tooth fatigue cracks, spalling, and overheating caused by inadequate lubrication or load exceeding design limits.

Common HEENAN DRIVES LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HEENAN DRIVES LTD equipment arriving at our workshop.
- ✓Heenan gearbox bearing cage collapse and bearing seizure — Extended operation without proper oil maintenance in dusty mill environments; bearing preload loss due to worn thrust washers or inadequate grease in older HC-series units. Typical in sugar mills after 2-3 seasons without oil analysis.
- ✓HDC controller capacitor bulging and circuit board tracking failure — High ambient temperature (40+ C) in mill control rooms combined with moisture ingress and undersized cooling fans on legacy HDC-110/220 units. Electrolytic capacitors fail first, followed by control relay malfunction.
- ✓Heenan shaft coupling elastomeric bushing brittle failure and catastrophic runout — UV degradation and thermal fatigue in outdoor conveyor systems; undersizing of bushing durometer for actual torque loads; poor installation alignment causing premature stress concentration in the elastomer.
- ✓Heenan solenoid-release brake coil open-circuit and mechanical jam — Moisture ingress into solenoid coil windings from washdown operations in food/sugar processing; thermal cycling causing lead solder joint cracking; contact welding in HB-Solenoid-Release units under high load.
- ✓Heenan bevel gear spalling and tooth fatigue cracks under peak crushing load — Alignment drift after foundation settlement in sugar mill crusher installations; contaminated lubricant (metallic debris) accelerating tooth pitting; design overload from processing harder sugarcane varieties.
- ✓Heenan transmission speed droop and intermittent stalling under full-load torque — Wear in clutch friction material or belt-drive slippage in older mechanical transmissions; oil viscosity breakdown reducing fluid film strength in hydrostatic bearings; erratic load feedback from faulty pressure transducers in modern HDC systems.

Frequently Asked Questions — HEENAN DRIVES LTD Repairs
Do you repair Heenan Drives equipment anywhere in India?+
Yes. Synchronics repairs the full Heenan Drives product range — gearboxes, drive controllers, couplings, brakes, and transmission gears — across all of India. We offer door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Vadodara, and all major cities. All repairs are completed in our Vadodara, Gujarat facility with 180+ engineers trained on UK Heenan Drives legacy and modern equipment.
What is the typical turnaround time for Heenan gearbox repair at Synchronics?+
Turnaround depends on fault severity. Standard bearing replacement and oil system flushing takes 5-7 working days. Complex gear tooth damage requiring metallurgical analysis and custom replacement gears takes 10-14 days. Emergency express repairs during sugar crushing season are available — call ahead to prioritize your unit. We supply loaner gearboxes to minimize your production downtime.
Can Synchronics repair my legacy Heenan HC-200 mechanical gearbox with no available spares from UK factory?+
Absolutely. Synchronics specializes in legacy Heenan Drives repair. For HC-series mechanical units, we source and reverse-engineer obsolete components — bushings, thrust washers, bearing rings — and manufacture them locally to original tolerances. We've rebuilt HC-200, HC-300, and HC-500 units still running in Indian sugar mills. Supply OEM-equivalent or upgraded material specifications based on your duty cycle analysis.
Does Synchronics provide warranty and performance certification on Heenan Drives repairs?+
Yes. All Heenan Drives repairs include 12-month parts and workmanship warranty. We provide signed performance test certificates confirming torque capacity, speed stability, bearing clearance, and lubrication system function. For critical installations, we offer 24-month extended warranty and post-repair vibration analysis reports — essential for sugar mill crushing seasons and cement kiln operation planning.
What preventive maintenance does Synchronics recommend for Heenan gearboxes in Indian mill conditions?+
For dusty Indian mill environments, Synchronics recommends: (1) Oil sampling every 3 months during season — watch for ferrous debris spikes indicating bearing wear; (2) Bearing temperature monitoring via non-contact sensors; (3) Annual gearbox oil flush and filter change; (4) Alignment check after monsoon/foundation settlement. We provide customized maintenance schedules for your equipment duty cycle and environmental exposure.
How do I send my HEENAN DRIVES LTD 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 HEENAN DRIVES LTD 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 HEENAN DRIVES LTD 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 HEENAN DRIVES LTD 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.
