Generator & Engine Component Repairs

Cooling, starting, charging, fuel and air systems — repaired at component level rather than replaced wholesale.

Radiator & Cooling System Repairs

Overheating destroys engines faster than almost any other fault, and on standby sets it usually appears the first time the machine is asked to take real load. We inspect, pressure-test and repair generator and industrial-engine cooling systems rather than condemning a radiator on appearance.

What the work covers

  • •Pressure testing to locate leaks under working conditions
  • •Core cleaning, flushing and blockage assessment
  • •Tube, core and end-tank repair where the core is serviceable
  • •Radiator cap and thermostat testing
  • •Hose, clamp and fan-drive inspection
  • •Coolant condition and inhibitor assessment
  • •Cooling-system troubleshooting on running sets

Symptoms we see

  • Coolant leakage
  • High-temperature shutdown under load
  • Blocked or fin-damaged core
  • Corroded or split end tanks
  • Contaminated coolant
  • Weak airflow through the radiator
Request Radiator Inspection

Starter Motors & Charging Alternators

A set that will not crank, or one whose batteries are flat when it is finally needed, is usually a starting or charging fault rather than an engine fault. Both are repairable at component level.

What the work covers

  • •Starter solenoid testing and replacement
  • •Armature, commutator and brush servicing
  • •Bush, bearing and Bendix-drive inspection
  • •Charging alternator diagnosis — output, regulator and rectifier
  • •Diode and rectifier pack testing
  • •Bearing replacement and terminal repair
  • •No-load functional testing before return

Symptoms we see

  • Engine will not crank
  • Slow or intermittent cranking
  • Batteries flat after standing
  • Charge warning during running
  • Grinding on engagement
Send Starter or Alternator Details

Injector Nozzle Testing & Repair

Injector faults show as smoke, rough running and poor load acceptance, and they are frequently misdiagnosed as engine wear. Injectors are assessed on test rather than by symptom alone.

What the work covers

  • •Spray-pattern examination
  • •Opening-pressure assessment
  • •Leak-back assessment
  • •Nozzle cleaning and carbon removal
  • •Nozzle-tip replacement where appropriate
  • •Cylinder-to-cylinder comparison
  • •Injector calibration where the equipment is available

Symptoms we see

  • Black smoke
  • Rough or uneven running
  • Hard starting
  • Knocking on one cylinder
  • High fuel consumption

Worth knowing: Some nozzles are beyond economic repair and replacement is the better outcome — we say so at inspection rather than after the work.

Book Injector Testing

Diesel Injection Pump Repairs

Mechanical and electronic injection pumps meter and time fuel delivery. Faults here affect starting, power and consumption together, and pumps are normally reconditioned and calibrated rather than replaced outright.

What the work covers

  • •Inspection and fault diagnosis
  • •Governor and delivery assessment
  • •Seal and fuel-leak repair
  • •Reconditioning and calibration coordination
  • •Timing verification on refit
  • •Fuel supply and filtration check to prevent repeat failure

Symptoms we see

  • Hard starting
  • Weak power output
  • Hunting or surging
  • Excessive diesel consumption
  • Fuel leakage
  • Poor acceleration under load
Request Injection-Pump Diagnosis

Turbocharger Inspection & Rebuild

Turbochargers spin at very high speed on a thin oil film, so nearly every failure traces back to oil supply, oil condition or ingested debris. We look for the cause as well as the damage — replacing a turbo without finding the cause usually destroys the replacement.

What the work covers

  • •Shaft play, bearing and seal inspection
  • •Compressor and turbine wheel assessment
  • •Housing inspection for cracking and contact
  • •Carbon deposit cleaning
  • •Oil feed and drain line investigation
  • •Boost-loss and oil-carryover investigation
  • •Rebuild or replacement recommendation with reasons
  • •Balancing and testing where the equipment is available

Symptoms we see

  • Loss of power
  • Blue or black smoke
  • Whining or siren noise
  • Oil in the intake pipework

Worth knowing: Not every damaged turbocharger is economically repairable. Where a rebuild is not sound engineering we will recommend a replacement instead.

Send Turbocharger Details

Complete Engine Overhauls

A full overhaul is a measured process, not a parts swap. The scope is set after dismantling and measurement, because what a worn engine actually needs is rarely what its symptoms first suggest.

What the work covers

  • •Initial diagnosis and compression assessment
  • •Dismantling and component measurement
  • •Cylinder head, valve and seat inspection
  • •Crankshaft, bearing and journal assessment
  • •Piston, ring and liner inspection
  • •Lubrication, cooling and fuel system assessment
  • •Gasket, seal and consumable replacement
  • •Reassembly to specified torques and clearances
  • •Static testing, controlled run-in and load testing where applicable

Symptoms we see

  • Blue smoke and high oil consumption
  • Low compression
  • Knocking under load
  • Metal in the oil or filter
  • Heavy crankcase blow-by

Worth knowing: The exact scope and cost are confirmed only after dismantling and measurement. We quote the inspection first, then the work.

Request Engine Overhaul Assessment

Electrical, UPS, Motor & Pump Repairs

Rotating electrical machines and backup power systems, diagnosed before any repair is quoted.

Alternator & Electric Motor Rewinding

Rewinding covers three distinct machines that are often confused: the engine charging alternator, the generator end that produces your output, and industrial electric motors. We assess which of these has actually failed before quoting, because the remedy and the cost differ sharply.

What the work covers

  • •Single-phase, three-phase, pump, compressor and fan motors
  • •Generator alternator stator and rotor windings
  • •Insulation resistance testing before and after work
  • •Rewinding where it is technically and economically sound
  • •Bearing, shaft and terminal repair
  • •Rotor inspection and balance assessment
  • •No-load and output testing after rewind

Symptoms we see

  • No output voltage
  • Output collapses under load
  • Burning smell or discoloured windings
  • Motor trips its protection on start
  • Insulation failure after standing or flooding
Request Motor RepairView motor rewinding details →

UPS Repairs & Battery-System Diagnosis

A UPS that has never been load-tested is an assumption, not a backup. We diagnose the unit and the battery bank together, because a healthy UPS with a tired battery bank still fails at the moment it is needed.

What the work covers

  • •Fault diagnosis and alarm investigation
  • •Battery bank testing and replacement assessment
  • •Charger and inverter fault diagnosis
  • •Bypass and transfer problems
  • •Cooling fan and thermal fault investigation
  • •Internal connection and termination inspection
  • •Runtime assessment against actual connected load
  • •Preventive maintenance scheduling

Symptoms we see

  • UPS alarming or on permanent bypass
  • No runtime on mains failure
  • Batteries not holding charge
  • UPS overheating or fans noisy

Worth knowing: Repair viability and price can only be confirmed after diagnosis — some units and battery banks are past economic repair.

Request UPS DiagnosisOpen the UPS Intelligence Lab →

Pump Repairs & Overhauls

Borehole, booster and process pumps usually fail through seals, bearings or the driving motor rather than the pump body. Diagnosing which saves replacing a pump that is still serviceable.

What the work covers

  • •Borehole, surface, booster, centrifugal and drainage pumps
  • •Mechanical inspection and electrical testing
  • •Mechanical seal and bearing replacement
  • •Impeller and shaft inspection
  • •Motor rewinding where required
  • •Alignment assessment on coupled sets
  • •Control panel and protection diagnosis
  • •Performance testing after repair

Symptoms we see

  • Reduced flow or pressure
  • Pump tripping on overload
  • Leaking at the seal
  • Noise or vibration
  • Motor overheating
Request Pump InspectionView borehole & pump services →

Generator Fabrication & Fuel Systems

Canopies, exhausts, tanks, plinths and security — fabricated to the machine and the site, not to a standard drawing.

Generator Canopy Fabrication

A canopy has to do three things at once: reduce noise, keep weather out, and still let the machine breathe. Getting the airflow wrong turns a noise solution into an overheating problem, so canopies are designed around the specific set.

What the work covers

  • •Generator dimensions and cooling-air requirement
  • •Radiator discharge and air-path design
  • •Exhaust routing and heat separation
  • •Access doors for service and refuelling
  • •Sheet thickness and structural frame
  • •Acoustic lining selection
  • •Protective finish for the installation environment

Worth knowing: We do not quote a decibel figure without acoustic design and measurement. Noise reduction is described in terms of the design approach, not a guaranteed number.

Request Canopy Design & Quote

Exhaust System Fabrication

An exhaust system carries hot gas safely away from people and plant. Done poorly it becomes a carbon-monoxide hazard and a source of back pressure that costs the engine power.

What the work covers

  • •Exhaust piping, bends and supports
  • •Flexible connections to isolate engine movement
  • •Silencer selection and mounting
  • •Wall and roof penetrations
  • •Rain caps and safe discharge routing
  • •Thermal insulation and personnel guarding
  • •Back-pressure consideration in the routing design

Worth knowing: Exhaust routing must account for heat, fumes, back pressure, nearby occupants and combustible materials. We assess the plant room, not just the pipe run.

Request Exhaust-System Assessment

Diesel Fuel Storage Tanks

Fuel storage determines how long a set runs unattended, and it is the part of an installation most often changed after commissioning. It is also where fire and environmental requirements apply most directly.

What the work covers

  • •Bulk, day and base tanks
  • •Bunded containment arrangements
  • •Tank supports and structural frames
  • •Fill, vent, suction and return connections
  • •Drain and inspection points
  • •Level indication provisions
  • •Protective coating for the installation environment

Worth knowing: Capacity, material, structural support, containment and ventilation are assessed against the site before fabrication begins.

Request Fuel-Tank Quotation

Fuel-Tank Automation & Monitoring

Automating fuel transfer removes the two most common diesel problems on a standby installation: a day tank that runs dry, and a bulk tank nobody notices is empty until the set stops.

Fabricated powder-coated control and distribution panels built by EmersonEIMS, one wrapped for dispatch, beside a board populated with miniature circuit breakers

What the work covers

  • •Level monitoring with high and low alarms
  • •Automatic transfer from bulk to day tank
  • •Transfer pump start/stop control with manual override
  • •Overflow protection
  • •Bund or leak alarm where specified
  • •Consumption monitoring for the generator
  • •Control panel indication
  • •Remote alerts by GSM or network where available
  • •Event and alarm history

Worth knowing: Only the monitoring functions specified and supplied for your project are provided — the list above is the available scope, not a standard package.

Discuss Fuel AutomationView diesel automation →

Generator Plinths & Foundations

The plinth carries the machine, controls its vibration and keeps it clear of water. It is designed from the actual generator weight and footprint and the actual ground conditions.

What the work covers

  • •Site measurement and ground assessment
  • •Generator weight and footprint confirmation
  • •Reinforced concrete base design and construction
  • •Anchoring and anti-vibration mounting provisions
  • •Drainage and water clearance
  • •Cable and conduit entry provisions
  • •Access clearance for service and refuelling

Worth knowing: There is no universal plinth size. Every foundation is designed for the specific set and site — we will not quote one from a photograph.

Request Plinth Assessment

Generator Security Cages

Outdoor generators and their fuel systems are theft targets. A cage protects the asset without becoming a new problem — provided it does not choke the machine.

What the work covers

  • •Welded steel construction to suit the site
  • •Lockable access doors
  • •Ventilation allowance sized to the cooling requirement
  • •Maintenance and refuelling access
  • •Weather-resistant finish
  • •Anchoring and anti-tamper detailing
  • •Provision for fuel and electrical connections

Worth knowing: A cage must never obstruct radiator airflow, exhaust discharge or maintenance access — that is designed in, not worked around afterwards.

Request Security-Cage Quote

Industrial Machinery Fabrication

Processing machinery built to a defined duty, material and output rather than copied from a photograph.

Hammer Mill Fabrication & Repairs

Hammer mills are specified from what they must process and what output is required. The same frame with the wrong screen, hammer or motor gives the wrong product at the wrong rate.

What the work covers

  • •Frame and grinding chamber fabrication
  • •Rotor assessment and hammer replacement
  • •Screen selection for the required output size
  • •Bearings, bearing housings and shaft repair
  • •Belt, pulley and drive arrangement
  • •Motor mounting and alignment
  • •Feed hopper and discharge arrangement
  • •Safety guarding

Worth knowing: Specification requires the material, target output size, expected capacity, available motor power, duty cycle and feeding method. We do not publish capacity figures that have not been established for your machine.

Request Hammer Mill Assessment

Industrial Grinder Fabrication

Size-reduction equipment is built to a defined duty. The material, the target particle size and the throughput determine the machine — not the other way round.

What the work covers

  • •Fabrication and repair for defined industrial applications
  • •Construction material selected for the process
  • •Drive and motor arrangement to the available supply
  • •Guarding and safety interlocks
  • •Feed and discharge design
  • •Installation and commissioning support

Worth knowing: We do not fabricate or quote machinery from a photograph alone. Material, output size, throughput, operating hours and electrical supply are required first.

How the workshop process works

The same six stages apply whether the item arrives by courier from Turkana or we attend your plant room in Nairobi.

  1. Stage 1

    Initial enquiry

    You send photographs of the equipment and its nameplate, the brand, model and serial number where available, a description of the fault, your location and any previous repair history.

  2. Stage 2

    Receipt or site assessment

    The component is delivered to our workshop, collected where arrangements are available, sent through an agreed courier or transport provider, or assessed at your site where the work needs field attendance.

  3. Stage 3

    Inspection and diagnosis

    Technicians establish the probable cause of failure, the parts required, whether the item is repairable, any safety concerns, and whether replacement would be more economical than repair.

  4. Stage 4

    Written quotation

    You receive the repair scope and quotation in writing. Major work does not proceed until you have approved it.

  5. Stage 5

    Repair, rebuild or fabrication

    The approved work is carried out with the appropriate materials, procedures and quality checks for the component.

  6. Stage 6

    Testing and handover

    Functional, electrical, pressure or load testing as applicable, with a summary of the work done and the parts replaced, then collection or dispatch by the agreed route.

A site survey and diagnostic fee covers the technician’s attendance, inspection and fault diagnosis. The full fee is deducted from the contract when the work is awarded to EmersonEIMS.

Send your component from anywhere in Kenya

You do not always need to travel to Nairobi to use the workshop. Suitable components can be sent to us by courier, parcel or transport service, and returned the same way once the approved repair is complete.

Transport options

  • •Established courier companies
  • •G4S courier services
  • •Wells Fargo courier services
  • •Matatu and bus parcel services
  • •Regional transport providers
  • •Your own nominated courier

Availability, packaging requirements, liability, insurance, cost and expected transit are confirmed with you before anything is dispatched.

Before you send equipment

  • ✔Drain fuel, oil or coolant where appropriate
  • ✔Protect exposed shafts and terminals
  • ✔Seal injector and pump openings
  • ✔Pack in strong, protective packaging
  • ✔Include your contact details inside the parcel
  • ✔Include the quotation or job reference
  • ✔Photograph the item before dispatch
  • ✔Share the consignment or parcel details with us

Please do not dispatch leaking, pressurised, hazardous or inadequately packaged equipment — it is a risk to handlers and often arrives damaged.

Request an inspection or quotation

Photographs tell us more than a description. Send the equipment and its nameplate on WhatsApp and our technical team will come back to you on inspection, the technical details still needed and the appropriate next step.

Please include

  • •Your name and company
  • •County and nearest town
  • •Service required
  • •Equipment type, brand and model
  • •Serial number from the nameplate
  • •Description of the problem
  • •Whether the equipment still runs
  • •Whether the item is on site or ready to dispatch
  • •Photographs of the equipment and nameplate
  • •Any date you are working towards
Start the enquiry on WhatsAppUse the contact form insteadCall +254768860665

We do not quote a repair price or completion date before inspection. Once we have seen the equipment you get a written scope and quotation, and major work begins only after you approve it.

Frequently asked questions

Can I send a generator component from another county?+

Yes. Components are regularly sent to us from across Kenya by courier, bus or matatu parcel service. Agree the route, packaging and cost with us before dispatch so the item arrives safely and we know to expect it.

Do you repair all generator brands?+

We work across the common industrial diesel brands including Cummins, Perkins, Caterpillar, Volvo, Lister Petter, Iveco and others. Whether a specific component is repairable depends on its condition and parts availability, which we confirm at inspection.

Do you inspect equipment before giving a final repair price?+

Yes. A meaningful price is only possible after inspection. We charge a site survey and diagnostic fee for the inspection, and the full fee is deducted from the contract when the work is awarded to us.

Can you collect equipment from our premises?+

Collection can be arranged in some cases depending on the item, the location and the schedule. Ask when you enquire and we will tell you what is practical for your site rather than promising in advance.

Do you repair both charging alternators and generator alternators?+

Yes, and they are different machines. The charging alternator keeps the starting batteries up; the generator end produces your output. We identify which has failed before quoting, because the work and the cost differ substantially.

Can you rewind an alternator or electric motor?+

Rewinding is offered where it is technically sound and economically sensible. On some smaller machines a replacement costs less than a rewind, and we will say so.

Can every injector, pump or turbocharger be repaired?+

No. Some components are beyond economic repair, and we tell you that at inspection rather than after starting work. Where replacement is the better outcome we recommend it.

Do repaired items receive testing before dispatch?+

Yes, where the equipment and available test facilities allow — functional, electrical, pressure or no-load testing as applicable to the component. The testing done is stated in the handover summary.

Can you fabricate a canopy for an existing generator?+

Yes. The canopy is designed around your machine, its cooling-air requirement and exhaust routing. We do not quote a guaranteed noise figure without acoustic design and measurement.

Can you automate an existing diesel fuel tank?+

Yes. Level monitoring, alarms, automatic bulk-to-day transfer and consumption monitoring can be added to existing tanks. The functions supplied are specified per project.

Do you construct generator plinths at the customer site?+

Yes. The plinth is designed from the actual generator weight and footprint and the ground conditions at your site. There is no universal size.

Can you design a hammer mill for a particular product?+

Yes, provided you can tell us the material, the output size you need, the throughput expected, the motor power available and how the machine will be fed. Those determine the design.

Do you repair UPS systems and battery banks?+

Yes. We diagnose the UPS and the battery bank together, since a serviceable UPS with an exhausted battery bank still fails when mains drops. Repair viability is confirmed after diagnosis.

Can repaired components be returned through a courier?+

Yes. Return is by the route agreed with you — courier, bus or matatu parcel, or your own transporter. We confirm the channel and cost before dispatch and tell you when the item has gone.

What information should I send before requesting a quotation?+

Photographs of the equipment and its nameplate, the brand and model, the serial number, a description of the symptoms, whether the machine still runs, your county and town, and any recent repair history.
