If your Perkins engine has reached the point where routine servicing won’t restore its performance, remanufacturing is often the most practical route forward. It costs significantly less than a new engine, and when done properly, a remanufactured Perkins will perform to original factory specifications.
But “done properly” is the key phrase. The quality of a remanufactured engine depends entirely on the standards applied during the rebuild process. Here’s what that process actually involves when carried out to British Standard BSI AU 257:2002.
Every remanufacturing job starts with a complete strip-down of your engine. This isn’t a case of removing a few worn parts — the engine is fully disassembled so that every component can be individually inspected and measured. This stage determines the full scope of work required and identifies any damage that might not be visible from the outside.
The engine block is bored back to standard dimensions and fitted with new cylinder liners. This restores the precise tolerances that the pistons and rings need to seal correctly and maintain compression. Even minor wear in the cylinder bores will cause oil consumption, blow-by, and lost power, so getting this right is fundamental to the rebuild.
The cylinder head is remanufactured with valve seats re-cut and new valves fitted where necessary. This ensures proper sealing in the combustion chamber and correct gas flow through the ports. A worn or poorly seating valve will compromise both power output and fuel efficiency, regardless of how good the bottom end of the engine is.
The crankshaft is ground to restore its journal surfaces to the correct dimensions. The crankshaft takes enormous loads during operation, and any wear on the journals will affect oil clearances and bearing life. After grinding, it’s paired with the correct undersize bearings to maintain factory-specification clearances.
The fuel injection equipment is remanufactured to ensure accurate fuel delivery and timing — both critical to performance and emissions. Where the original engine is turbocharged, a remanufactured turbocharger is also fitted.
The engine is reassembled in a clean workshop environment using new pistons and rings, bearings, oil pump, water pump, and a complete set of new gaskets. All other components are inspected during reassembly and replaced if they don’t meet the required standard.
Using new wear components throughout isn’t optional if you want an engine that performs like new. Reusing old pistons, rings, or bearings to cut costs simply shifts the problem down the line.
Once assembly is complete, the engine is run on a dynamometer. This isn’t a quick idle test — the dyno confirms that the engine produces the correct power and torque figures, that oil pressure and temperatures are within specification, and that there are no leaks or issues under load. Any engine that doesn’t meet its rated performance goes back to the bench.
After testing, the engine is sprayed in a hard-wearing black paint and secured to a pallet ready for shipping. Final quality control checks are carried out before dispatch.
Timik Engines are members of the Federation of Engine Re-Manufacturers (FER). This means every remanufactured engine is required to meet BSI AU 257:2002, the British Standard code of practice for engine remanufacturing. This standard sets out specific requirements for the inspection, machining, assembly, and testing processes, ensuring a consistent level of quality that generic “reconditioned” engines often can’t match.
It’s worth understanding the distinction here. The term “reconditioned” is unregulated — it can mean anything from a basic freshen-up to a comprehensive rebuild. “Remanufactured” to BSI AU 257:2002, on the other hand, means the engine has gone through a defined, auditable process with specific quality benchmarks at each stage.
Remanufactured engines from Timik come with a 12-month warranty from the date of invoice. The warranty covers any defects or faults arising from the remanufacturing process, materials, or components under normal use and maintenance as specified by the original manufacturer.
Remanufacturing makes sense when the core engine (the block) is structurally sound but the wear components have reached the end of their service life. Common signs include rising oil consumption, loss of power, excessive smoke, or low compression across cylinders.
If you’re unsure whether your Perkins engine is a candidate for remanufacturing, get in touch. We can advise based on the engine series, its current condition, and what you need it to do.
