Engine Overhaul & Repair
Engine overhauls done right; Factory-Spec rebuilds from our HQ
Every engine that comes through our workshop undergoes a rigorous overhaul to return it to original factory specifications. Backed by decades of experience as official dealers and distributors of the OEM, our team combines deep technical expertise with genuine parts knowledge to go beyond a simple repair, fully reconditioning your engine to perform like new.
With all major work carried out at our headquarters and field service available across the UK, we’re equipped to keep your operation running wherever you are.
Our process includes:
Inspection, Measurement & Evaluation
Every engine is overhauled from the ground up. They are disassembled part-by-part to clean, qualify and test, including a complete engine disassembly, paint and rust removed from all parts and components. All components are screened for the possibility of reuse to minimise cost for the customer. New components needed are always and exclusively genuine OEM parts, supplied from our in-house stock. Quality inside means you get a more reliable, dependable remanufactured engine.
Engine Re-Assembly
The engine reassembly processes include using remanufactured/rebuilt parts and components and new wear parts (gaskets, seals, bolts, screws, etc.) All new parts used are always OEM Genuine Parts. Our in-process inspection and tests will adhere to inspection plans, OEM specifications, including documentation of key dimensions throughout the re-assembly process.
Acceptance Testing & Final Preparation
Our engine test cell can handle most brands of diesel engines up to 3000bhp, and we can facilitate complete engine dynamometer testing to verify performance under expected operating conditions. FAT’s can also be facilitated (optional upon request). ,Following final inspection and test engines will be primed, painted, and packaged/preserved as per customer specification, ready for despatch.
