Renovation of CATERPILLAR engines and parts

Renovation workshops: a second lease of life for your engines and parts

We know that machine downtime can impact your activity. This is the reason why Eneria has invested in its own renovation workshops for engines (the ARME engine renovation workshop) and parts (the SAVE parts renovation workshop).

Eneria proposes a global services and maintenance offer: preventive maintenance, oil checks, maintenance contracts, Caterpillar warranties, spare parts, engine renovations and system optimisation.

The Eneria Services and Maintenance team supports you by proposing a broad and personalised offer that meets your needs, irrespective of the type of Caterpillar engine or part. Engine and parts renovations provide faster access to new equipment, while also protecting the planet by giving a second lease of life to your equipment, but most importantly, they enable you to make significant savings by opting for renovated parts or engines.

Maintenance and renovation of Caterpillar engines: give a second lease of life to your engine

Since 2020, the Maintenance and Services teams at Eneria have been renovating your Caterpillar engines in our new ARME engine renovation workshop, located on our manufacturing site in Montlhéry, near Paris.

Our experts renovate Caterpillar engines that are more powerful than 2 MW. Engines that are less powerful than 2 MW are renovated in the Monnoyeur Component Reconditioning Centre (CRC) in Brie-Comte-Robert, France.

What are the main steps of the renovation of a Caterpillar engine in the Eneria renovation workshop?

Unloading and cleaning

When the engine arrives in the unloading zone in Montlhéry, the teams clean and degrease the engine, before sending it to the engine renovation workshop.

1

Disassembly of the engine

When the engine arrives in the engine workshop, it is completely disassembled by our technicians. Every part is machine-washed, then sand-blasted to remove any imperfections from the parts.

2

Reassembly of the engine

Once the parts of the engine have been cleaned, the engine is transferred to the reassembly zone. Every part of the engine is checked and replaced, if necessary. Eneria uses new or re-manufactured Caterpillar parts, or parts from our component renovation workshop. The Eneria technicians are trained and certified by Caterpillar in order to reassemble the engines.

3

Engine tests

Once the engine has been reassembled, it is sent to the test bench in order to test all the technical elements. This step is essential before installation on the customer’s site. The compliance and performance of the engine are checked.

Maintenance and renovation of Caterpillar parts and components

The component renovation workshop reconditions cylinder heads, turbos, water pumps and dampers according to the Caterpillar standard exchange process.
