Diesel generator repairs and upgrades

As an alternative to purchasing a completely new power system, one option available to you is to upgrade or refurbish your existing system. Our experienced in-house team can ensure that your trusty system is brought up to date and ready to continue to supply reliable power.

Our team has full capability, training and work to certified ISO standards to completely strip and rebuild any type of engine from basic generators through to twin bank diesels, CHP units and locomotives too.

All components we use in the refurbishment of an engine are to the manufacturer’s OEM specification. For older models where replacement parts are unavailable, a reconditioned part may be used but will remain set to a manufacturer’s OEM specification. All reconditioned parts supplied from stock have all undergone a full inspection and factory overhaul and are backed up by a full 180-day warranty.

As well as individual parts, we also specialise in factory reconditioning of sub-assemblies, including; crankshafts, nodal damper couplings, cylinder heads, water pumps, oil pumps, fuel pumps, fuel injectors, turbochargers, connecting rods and intercoolers, etc. We can also help you with the following services:

  • Engine refurbishment
  • Alternator refurbishment
  • Control panel upgrades
  • Cooling system upgrades
  • Fuel system design and upgrades
  • Acoustic upgrades
