Finning invests in Cat engine testing

Finning UK & Ireland is investing more than £200,000 in advanced engine testing technology as plant owners place greater emphasis on rebuild quality, uptime, and whole-life fleet performance.

The programme includes upgraded dynamometer engine testing across the Finning network, with the latest development centred on the company’s Cannock headquarters. A new £160,000 high-power dynamometer has been installed to certify the build quality, strength, and power output of engines being overhauled through Finning’s component rebuild centre operations.

The test cell investment forms part of a wider rebuild centre of excellence workshop under construction at Cannock. The 1,230 sq m unit is being developed to meet growing demand for machine rebuilds and major reconditions, including Cat Certified Rebuilds and machines prepared under Finning’s “Rebuilt and Ready to Go” programme.

Dynamometer testing provides controlled measurement of power, torque, and force, allowing engineers to validate engine performance before equipment returns to work. In rebuild operations, that verification step is central to quality control because it confirms whether workshop output can perform reliably under load.

Fleet management is becoming a more calculated exercise for contractors, quarry operators, and infrastructure suppliers. High replacement costs, longer lead times, capital constraints, and downtime risk are pushing more businesses to extend machine life through planned rebuild and reconditioning programmes. A rebuilt engine is increasingly part of an asset strategy rather than a last resort after failure.

Finning’s investment also reflects the growing technical demands placed on plant support providers. Modern machines are more software-driven, emissions-controlled, and data-rich than previous generations, which means rebuild processes need stronger diagnostics, tighter certification, and clearer performance evidence. Fuel efficiency, emissions performance, reliability, and warranty confidence all depend on repeatable testing.

Recent equipment developments show how quickly construction plant is moving into a more technology-led phase. HD Hyundai’s autonomous excavator deployment on a live Swiss construction site and Atlas Copco’s hybrid generator expansion for site power both highlight the move towards data, electrification, automation, and tighter performance control. Finning’s investment addresses a less visible but equally important part of that transition: keeping high-value equipment productive across multiple service lives.

The commercial case is direct. Major plant assets carry high upfront costs, and unplanned downtime can disrupt earthworks, quarrying, lifting, materials handling, or infrastructure programmes. Reliable rebuilds can delay replacement decisions, reduce whole-life cost, and keep familiar machines within a fleet for longer.

There is also a sustainability dimension to the rebuild market. Extending the life of machines and major components can reduce the demand for new manufacturing, shipping, and disposal, although the carbon case depends on the efficiency and emissions performance of the rebuilt asset. Testing and certification help strengthen that case by proving that reconditioned equipment is not simply running, but performing to specification.

Aftermarket support, rebuild capability, and component testing are becoming more central to the construction plant market. Contractors are not only buying machines; they are buying uptime, technical assurance, access to specialist infrastructure, and evidence that assets can continue working safely and efficiently.

For Finning, the new dynamometer capacity strengthens its rebuild offer at a time when contractors are scrutinising capital expenditure and asset utilisation. For equipment owners, the value will be measured in fewer failures, clearer performance evidence, and stronger confidence that rebuilt engines can return to demanding site workloads.
