Generator Maintenance & Repair
Millennium Power (MPOM) provides specialist generator repair and maintenance service for diesel generators for industrial, commercial, and facility clients across Dammam, the Eastern Province. Our workshop in Al-Sinaiyah, Dammam, is equipped to handle generators from 10 kVA portable units up to 2,000+ kVA standby and prime power sets. We service all major OEM brands including Cummins, Perkins, MTU, Doosan, Kohler, FG Wilson, Caterpillar, Aksa, and SDMO – supported by Nexiq and Jaltest diagnostic platforms and an OEM-trained technical team.
Our technicians perform detailed inspections and diagnostics to identify wear, performance issues, or early signs of failure before they cause unexpected outages. Based on these findings, we carry out preventive maintenance, corrective repairs, component replacement, and complete engine or alternator overhauls to restore reliable generator performance.
Each service follows clear procedures and checklists aligned with OEM recommendations and relevant industry standards, helping you maintain compliance and reduce unplanned downtime.
Who We Serve:
Our generator maintenance clients include hospitals and clinics, data centers, telecom sites, industrial plants, construction project camps, marine and offshore facilities, agricultural and farming operations, municipal facilities, and logistics depots. Each application has different reliability and load-profile requirements — a hospital generator that needs to start in 10 seconds is a different problem from a construction site generator running 18 hours a day at 60% load.
Whether your generator supports a plant, data center, hospital, or commercial facility, our goal is to keep your backup power system operating safely, efficiently, and with maximum availability at all times.

24-hour callout for contract clients across the Eastern Province. Typical response time: 4-8 hours within Dammam metro, 8-12 hours for outlying areas (Jubail, Al-Ahsa). Mobile workshop and tools come to your site.
Annual load bank testing at 30%, 50%, 75%, and 100% of rated kW capacity. Identifies cooling system weaknesses, AVR drift, governor problems, and exhaust restrictions before they cause failure under real load.
AVR fault diagnosis, replacement, and parameter setup for Stamford, Mecc Alte, Marathon, Leroy Somer, and Caterpillar units. Common faults addressed include voltage hunting, no excitation, overvoltage trip, and harmonic distortion.
Injector testing and replacement (Bosch, Denso, Delphi, Stanadyne), fuel pump calibration, common rail diagnostics, and fuel tank cleaning. We also offer day-tank service and water-in-fuel remediation.
Read and clear fault codes, live parameter logging, and ECU re-flashing where supported by the OEM. Covers Cummins CM2150/CM2250, Perkins 2800, MTU ADEC, Doosan ECU, and most Caterpillar engine controllers.
Complete engine rebuild including cylinder honing or re-boring, crankshaft inspection and grinding, head reconditioning with valve seat work, new piston and ring assembly, full gasket and seal kits, and post-overhaul break-in run.
Generator Brands
We work on the diesel engines that power most industrial generator sets in Saudi Arabia: Cummins QSB, QSL, KTA and Quantum series; Perkins 1100, 1500, 2300, 4000 series; MTU 2000 and 4000 series; Doosan P086, P126, P158; Kohler KD series; & Caterpillar 3406, 3412, 3508, 3512, 3516.

Our Capability Edge
Three things differentiate MPOM in the Eastern Province industrial maintenance market.
- Our investment in diagnostic equipment – Nexiq and Jaltest platforms cover virtually every modern engine controller, removing the guesswork from intermittent faults.
- Our spare parts pipeline – we hold stock of fast-moving consumables (filters, belts, AVRs, sensors) for the brands we service most frequently, so common jobs don’t wait on imports.
- Our technical team is OEM-trained on diesel engines specifically, not generalist mechanics – they read fault codes the way other workshops read ammeters.

Frequently Asked Questions
MPOM services all major industrial diesel generator brands: Cummins, Perkins, MTU, Doosan, Kohler, FG Wilson, Caterpillar, Aksa, and SDMO. Our technicians are OEM-trained and use Nexiq and Jaltest diagnostic tools for fault code reading, live parameter monitoring, and ECU/ECM programming across all major engine platforms.
Standby generators should receive a minor service every 250 running hours or 6 months (whichever comes first), and a major service every 500-1,000 hours. Continuous-duty generators in industrial sites require more frequent service. We recommend a Preventive Maintenance contract that includes scheduled inspections, oil and filter changes, coolant checks, AVR testing, and an annual load bank test.
A load bank test applies an artificial electrical load to the generator to verify it can produce its rated kW output under controlled conditions. This is critical because a standby generator may run weekly but only at low load — which causes wet stacking, fuel dilution, and undetected weaknesses. Annual load bank testing at 80-100% of rated capacity is best practice for critical-load installations such as hospitals, data centers, and industrial plants.
MPOM supplies genuine and OEM-equivalent parts including filters from Fleetguard, Donaldson, and Baldwin; AVRs from Caterpillar, Stamford, Mecc Alte, Leroy Somer; injectors and fuel pumps from Bosch, Denso, Delphi, Stanadyne; turbochargers; starter motors and alternators; coolant pumps; thermostats; and complete gasket kits. Common parts are stocked; specialty items are imported on a typical 7-14 day lead time.
Yes. MPOM provides on-site maintenance and emergency callout across Dammam, Al-Khobar, Dhahran, Jubail, Al-Ahsa, Qatif, and the surrounding Eastern Province. For workshop work, generators can be transported to our facility in Al-Sinaiyah, Dammam. Emergency callout response is typically within 4-8 hours for clients with active maintenance contracts.
Pricing depends on generator size, brand, and service scope. A minor PM service for a 100-500 kVA generator typically ranges from 1,200 to 3,500 SAR. A major service can range from 3,500 to 12,000 SAR. Annual PM contracts typically save 20-30% compared to ad-hoc service calls and include priority breakdown response.
