Problems We Solve
Mechanical Faults Requiring Professional Attention
Early diagnosis and repair can prevent serious machinery damage, extended downtime and increased operating costs.
Loss of Engine Power
Reduced performance caused by fuel, air, compression, turbocharger or internal mechanical problems.
High Temperature
Cooling-system, lubrication, combustion or heat-transfer faults causing abnormal operating temperatures.
Abnormal Noise & Vibration
Bearing wear, alignment issues, loose components, damaged gears or rotating machinery problems.
Oil or Water Leakage
Seal, gasket, pipeline, cooler or component failure resulting in leakage and reduced reliability.
Excessive Smoke
Fuel injection, turbocharging, combustion, air supply or engine-condition problems.
Starting Failure
Mechanical, fuel, compression, air-start or control-system issues preventing reliable engine starting.
Our Repair Process
A Controlled Engine Overhaul Procedure
Every overhaul is completed through a clear sequence of inspection, measurement, repair, assembly and testing.
Step 01
Initial Inspection
Our engineers inspect the engine, machinery and operating condition to identify faults and define the required repair scope.
Step 02
Dismantling & Measurement
Components are dismantled, cleaned, visually inspected and measured using suitable precision instruments.
Step 03
Repair & Replacement
Damaged or worn components are repaired, machined, serviced or replaced according to technical requirements.
Step 04
Reassembly & Alignment
The machinery is reassembled using controlled procedures, correct clearances, torque values and alignment checks.
Step 05
Testing & Handover
The repaired engine or machinery is tested, monitored and inspected before final handover to the client.
Quality & Testing
Precision Inspection Before Final Handover
Mechanical repair requires accurate measurement, correct assembly and controlled testing. Our team checks critical components and operating conditions before the machinery is returned to service.
Visual inspection and condition assessment
Precision measurement of critical components
Bearing and clearance verification
Torque-controlled assembly
Alignment and rotation checks
Lubrication and cooling-system verification
No-load and operational testing
Final technical inspection before handover
