Repair scope

What we rebuild.

Alternator rewinding

Full stator and rotor rewinding in our workshop. Insulation testing, winding to original spec.

Top-end overhaul

Cylinder head, valves, valve seats, injectors, head gasket. Genset usually back on load within 3–5 working days for mid-KVA jobs.

Full engine overhaul

Bottom-end + top-end. Crankshaft inspection, liners, pistons, rings, bearings — all rebuilt to original tolerances.

Fuel system & injectors

Injector pop testing, calibration, fuel pump rebuilding. We catch fuel-side issues that get misdiagnosed as engine wear.

Governor & control

Mechanical and electronic governor service, AVR replacement, control card diagnostics.

On-site vs workshop

Most fixes happen on-site in Gurgaon to minimise downtime. Rewinding, full overhaul and crank work come into the workshop.

Frequently asked questions

Where do you repair generators for Gurgaon customers?

On-site is the default for most repair work in Gurgaon — less downtime, no logistics. We bring the genset into our workshop only when the work needs it: rewinding, crank or block work, anything requiring a clean environment or specialised tools. Workshop work for Gurgaon customers is dispatched from our Gurgaon office.

Do you rewind generator alternators?

Yes — both stator and rotor. We maintain a dedicated rewinding section in the workshop. Insulation class is matched to the original.

Can you handle a full engine overhaul?

Yes. Top-end (head, valves, injectors, gaskets) and full overhaul (crank, liners, pistons, rings, bearings) are both handled in-house with reliable parts.

How long is the genset down for an overhaul?

Mid-KVA top-end: 3–5 working days. Full overhaul: 10–14 days assuming parts are in stock. We can sometimes provide a rental DG for the overhaul window — ask when scoping.

Which areas of Gurgaon do you cover?

We cover all of Gurgaon including Udyog Vihar, Sector 18, Sector 35 IMT Manesar, Sohna Road, Golf Course Road and surrounding industrial belts.
