The method in the madness

See the steps we undertake below for our engine refurbishment process.

Step 1. Inital Survey

On receipt of the engine at our workshop facility, an initial survey will be completed to document the general condition of the engine any highlight and deficiencies at an early stage of the process.

Step 2. Engine Strip and Inspection

The engine strip will commence, removing all major components from the engine, to progressively facilitate the removal of the Crankshaft from the block, enabling an in-depth examination and concise survey of the machine.

At this stage of the process, our client would be invited to inspect the condition of critical parts and discuss their specific requirements to recondition the complete engine back to its optimum condition.

Step 3. Critical Component reconditioning

Specific components such: as Crankshafts, Turbochargers, Alternators and Coolers, which will require specialist overhaul facilities, are then be distributed nationwide via a network of approved specialist suppliers. Rebuild parts and new components required for the engine rebuild are sourced through a variety of OEM and approved aftermarket suppliers.

Original components which can be reconditioned and reused, are cleaned, inspected and recertified within our workshop.

Step 4. Engine rebuild procedure

The engine rebuild will commence following a thorough clean, inspection and re-certification of all components. The engine is rebuilt by experienced and knowledgeable engineers, who work to exact procedures as detailed by original OEM manufacturers.

Critical components such as main bearings, connecting rods, pistons and cylinder heads are assembled in a built for purpose work facility, with all running tolerances measured and recorded at each stage of assembly.

On completion of the rebuild process the engine is pre-lubricated and the complete Oil system is flushed. Finally the rebuilt engine is re-sprayed prior to despatch.

Step 5. Documentation and Service Support

A concise build report is compiled throughout the engine overhaul procedure, detailing every aspect of the rebuild; Component serial numbers and specific assembly location are recorded, along with all build specification and running tolerances of critical components.

Once the engine is re-installed on-site and our client is ready to run, a GS service engineer will attend the site, to assist with re-commissioning checks and subsequent bearing trials.
