Gentech diesel
We repair and service Gentech diesel generators across Gauteng, on standby and commercial sites. Gentech supplies generators in South Africa built around engines from other makers, so we read both the Gentech plate and the engine plate before we start.
Independent service and repair: Gentech is a trademark of its owner, and ProService Generator Repairs is not a Gentech dealer or agent.
Callout fee waived when you accept our written quote. 1-year workmanship guarantee. See prices

A Gentech diesel can carry another manufacturer’s engine under the Gentech badge. We record both plates, then follow the engine plate for fuel parts and the Gentech plate for electrical ones.
Gentech also sells petrol generators. If yours runs on petrol, book Gentech petrol generator repairs.
We change the engine oil and filters to the schedule on the engine plate, and check the battery on standby and commercial installations.
Every service includes a review of the alarms on the Gentech panel.
We work on Gentech diesel sets for standby and commercial use where access allows. The plate gives us the kVA and engine details.
When a Gentech diesel will not crank, we check the battery, the starter and any panel inhibit.
When it cranks without firing, we trace the fuel filter, air in the lines and the solenoid.
We diagnose the fuel path on the engine fitted, which may be another manufacturer’s block inside the Gentech canopy.
We trace rough running under load through fuel delivery before we quote injectors.
Depending on the model, the panel on a Gentech diesel may be a third-party controller. We read it as displayed and trace each alarm for that controller.
When the set runs but the building does not transfer, we test the ATS and the panel’s start output.
For overheating, we check coolant, the radiator and the fan.
We measure voltage at the breaker once engine speed is stable, then the AVR and alternator.
We read the Gentech plate and the engine plate, then check the canopy, engine and controller.
Book a repair when your Gentech diesel fails to start, trips on load or loses output.
Book a service when fluids are due and the set still runs.
A Gentech diesel can idle evenly and struggle under commercial load. We compare fuel delivery and alternator capacity with the load applied.
A filter or battery repair on a moderate-hour Gentech diesel is almost always worthwhile. Major engine work is a closer call.
When the engine, alternator and panel all need major work, we price a complete replacement set alongside the repair.
Your cost depends on the engine inside the set, the panel type and where the fault is. A fuel pump repair or replacement typically costs R1,800 to R4,500.
