Overhaul to revitalise your engine
A complete overhaul of your Perkins engine may happen only once or twice during its life and is not the simplest of tasks. However, there are considerable advantages in the overhaul process. It extends the life of the engine significantly and returns performance to – or near to – the level of a new engine.
Your Perkins engine is designed to have a life of thousands of hours and if you follow the recommended service schedules correctly, that is exactly what it will deliver. However, at some point even a thoroughly observed maintenance regime may not be sufficient and your engine may need overhauling.
The principal advantage of overhaul is greatly improved performance at a considerably lower cost than replacing the engine with a new one.
Significant savings
By replacing many of the main parts of the engine but retaining the core elements, such as the main engine block, you can make appreciable savings on the cost of simply replacing it – even taking into account the engineering time that is needed for this process.
Exactly what you choose to replace will depend on the areas where your engine performance is less than it was. If there is such a thing as a typical engine overhaul, it will involve the boring out of the cylinders, along with the installation of new piston rings, bearings and gaskets. Crankshafts and cylinder heads can either be replaced or reconditioned.
Improved economy
Importantly, the rebuilding process restores the engine compression – and it is the efficiency of this compression process which allows the engine to generate more power. Another advantage is that because the engine operates more efficiently again, fuel economy should improve in line with this. Perkins distributors are trained to carry out complete engine overhauls, and they have access to specifications and the latest part numbers to ensure that engine performance is fully restored, which returns performance to – or near to – the level of a new engine.
