SERVICE
GET YOUR CYLINDER IN TOP SHAPE!
Athena supports you in restoring and repairing aluminum endothermic cylinders with nickel silicon facing.
Athena can intervene on worn aluminum cylinders, eliminating the surface facing and reapplying a new Motor Nicksil facing, with final diamond lapping.
To carry out these processes, Athena uses the same machinery and technologies employed to produce its cylinders, which are then destined both for its Aftermarket offer and for the manufacturers of some of the best-known brands in the sector.
Depending on the conditions, wear, and seizure, our specialized staff can intervene with different services to restore your cylinder. Read on to learn more!
Environment
Our commitment to a sustainable future
From the perspective of responsible resource management and in line with the company philosophy, this cylinder restoration service fosters economic development that is more respectful of the environment. It reduces resources used and promotes the reuse of an existing product.
THE MOST COMPLETE INTERVENTION
RESTORATION OF THE BARREL FACING
This is the intervention our customers choose most often: we remove the worn, damaged or detached layer on the barrel, and then reapply a new one via Nikasil coating.
The composition of the blend used by Athena is unique and it is the result of years of experience in the sector.
The deposition process is constantly monitored by qualified personnel from our chemical laboratory, with the aim of obtaining high surface hardness and suitable wear resistance to guarantee excellent performance, durability and reliability of the engines.
Find out how we completely reapply the Nickel-Silicon alloy surface facing right now!
ATTENTION: Athena cannot restore cylinders with original chrome facing.
Removal of worn-out coating
The previous layer is removed with weak acids and bases that do not damage the cylinder's aluminum structure in any way.
Analysis
Analysis and dimensional verification of the barrel and critical areas.
Application of the new coating
Application of the new coating using a galvanic bath.
Sanding
The barrel is sanded to ensure a perfectly cylindrical shape and perpendicularity with the cylinder deck.
Finish
Exhaust and intake ports are deburred.
Sandblasting
Sandblasted finish of the external part of the cylinder.

Additional services for you
EXHAUST BRIDGE MACHINING
On 2-stroke engines, machining is carried out on the exhaust bridge in the exhaust port to allow perfect alignment with the internal barrel. The exhaust bridge is carefully lightened by a few hundredths to ensure maximum efficiency and interaction between the piston, rings and cylinder barrel. This processing phase makes it possible to increase the reliability, performance and durability of the piston over time.
ADDITIONAL SERVICES FOR YOU
CYLINDER HEAD SUPPORT RESURFACE
The cylinder deck may present irregularities or not have the correct roughness due to overheating, detonation, or damage during the engine overhaul. This can lead to damage to the cylinder-head gasket and the potential negative effects that can result. The flatness of the cylinder deck and of the o’ring grooves is therefore restored, ensuring a better seal and engine efficiency.
ADDITIONAL SERVICES FOR YOU
INTERNAL WELDING
The welds, carried out in our production departments, make it possible to recover cylinders that have been seriously damaged. However, in situations such as heavy seizures when the cylinder is structurally compromised, our technicians evaluate the effective possibilities of reparation. If the chances of recovery are very low, the process would not be done.
ADDITIONAL SERVICES FOR YOU
ANTI-KNOCK RING
We use numerical control machines to make a slot on the cylinder, which allows the application of a bronze ring by interference.
This intervention has the purpose of considerably reducing the risks linked to self-ignition or knock, which can erode the cylinder head surface and consequently compromise the seal of the gaskets and the relative efficiency of the engine.
ADDITIONAL SERVICES FOR YOU
SMOOTH FINISH OF THE CYLINDER
This is one of the final phases of the complete restoration process, and it is sufficient for cases of light seizures in which the facing has not been affected. The perfect roundness of the barrel is restored and surface roughness is reduced to a minimum, with tolerances of 0.005 mm or customized parameters for the customer (e.g. +0.01 mm).
The execution of the “cross hatch" will create micro-scratches on the surface of the barrel which retain the oil and guarantee ideal lubrication.
ADDITIONAL SERVICES FOR YOU
BARREL BORING – OVERBORE
The increase in the internal diameter of the cylinder leads to the consequent increase in the displacement. The machining is carried out according to the customer's instructions, once the possibility of boring the cylinder has been evaluated considering the residual structural rigidity.
For 2-stroke cylinders, the internal openings are also reprocessed with a correct angle and possible recovery and lowering of the exhaust bridge.
