What Is Involved in Reconditioning a Diesel Engine

Across the industry, you’ll find that dealers and resellers are likely to take liberties with what they consider to be a reconditioned engine. This is partly because there are no strict, government- regulated guidelines for what passes as a reconditioned engine. This is one of several reasons that we maintain membership with the Engine Reconditioners Association (ERA). Doing so helps to assure our clients and customers that we adhere to high standards and stand by our work.

To give you a better idea of what we mean when we talk about reconditioned diesel engines, here are a few of the key areas that we address in the process of rebuilding an engine:

Engine Block

Firstly, the entire engine block will be disassembled. It will be cleaned in a hot acid bath, which completely removes any built-up grease, grit and dirt. Once this is done, we’ll check crankshaft tunnels to ensure they’re true and within manufactures specifications. If necessary, we will also line bore your cylinder block. After this, we will check the engine’s deck height and cylinder decks for wear and inperfections , counter bore depths and for cracks and to see if they are flush. We’ll surface grind the deck face and recut counter boresIf it is a wet selvve block we with ensure your lower seal areas serviceable and not to badlt corriedPArretn bore engine we ensure your parent bores are not cracked and with a reusable condition, before we fit the standard or oversize liner Finally, cam bearings will be replaced as needed.


Camshafts need to be straightness , hardness and free of cracks. We will test everything regards before grinding each camshaft as necessary. After that, we will also re-profile camshaft followers or even replace them if required.

Connecting Rods

Also known as ‘conrods’, these components undergo substantial strain when the engine operates. Reconditioning them is significantly more affordable than replacing them – and we’ll be able to determine relatively quickly whether or not this is an option. If so, the connecting small end bush will be replaced and resized. The big ends of the rods will be closed and honed before they are re-sized.


We mentioned checking the crankshaft tunnels for trueness above. We will also check the crankshafts themselves to ensure they’re straight. In addition, they will be lector magna flux checked for cracks. Any problems in this regard will be corrected through a process of grinding and polishingand will make sure the oil seal area is re- useable.hanged. It was popula

Timing Gear

As part of the reconditioning process, we will inspect all timing gear bushes. Those that are in disrepair will be replaced.

Cylinder Head

Several problems can develop with the cylinder head of a diesel engine. To begin with, broken valves can lead to serious damage over time. Likewise, insufficient use of coolant can lead to cracks and corrosion of the cylinder head. Our team will crack- and pressure-test the cylinder head before checking it for straightness. It will then be reconditioned as necessary.

Rocker Arm

There are two main problems to look for on the rocker arm. The first is bushing wear, which can lead to problems with the reconditioned camshaft if not addressed. The second problem to look for is excessive wear on the rocker arm and face. After an inspection, replace rocker shafts and rocker bushes if necessary.

Oil Pump

Reconditioning the oil pump is a relatively straightforward matter. We’ll overhaul the oil pump if possible. If it would be better off replaced, we will swap it out with a new pump.

You’ll be amazed at the difference in performance once we’ve set you up with a reconditioned engine in Perth. Your vehicle or machinery will operate much more efficiently – with greater power and a much longer lifespan. And all of this is possible without the need to purchase a newly manufactured engine.
