ATHENA GASKETS, IN THE HEART OF EVERYONE BIG PROJECT The head gasket is a technological component, complex and fundamental. To meet the continuous needs of the market, Athena subjects the head gaskets to intense tests control, both during the design phase and during bench tests. Athena head gasket can be produced using different technologies, for example the metal/elastomer combinations or multilayer with steel materials and Athena coating. Choosing an excellent quality gasket is the first step towards the reliability of your engine.

FLOORING PROCESS Each gasket is smoothed out to achieve the optimal flatness, according to the required tolerances. 2. SILICONE EDGING A border is applied during processing silicone on critical areas of the gasket, to increase it the seal around the water and oil passages. 3. FINISH The application of different treatments to the surface allows the gasket to have a better performance, prevents any adhesion phenomenon and ensures resistance to high temperatures. GASKETS MULTILAMELLAR (code 338 > ) MLS Athena gaskets are designed to offer a superior hold, thanks to the wide choice of thicknesses and edging on oil and water passages with respect to the product OEM. The gaskets are formed by layers of stainless steel first quality and high elastic memory (from 2 to 5 layers). For sealing the combustion gases on the cylinder bore is folded sheet metal technology is used. In the end, a special coating applied to the surfaces of the Gasket ensures seal against small imperfections. CHARACTERISTICS – Designed ad hoc to respond to pressure in the cylinder and increasingly higher temperatures (le Athena multi-lamellar gaskets are installed by many car manufacturers as original equipment). – Manufactured in AISI 301 stainless steel with high elastic memory (full hard material). – Equipped with a combination of 3 to 5 slats internal and external, they are suitable for resisting levels compression higher than the configurations standard. The types of steel used for the slats can vary according to the needs of the engine. – Provide excellent holding power across the entire surface surface evenly, to compensate for any type of cylinder bore distortion. – They are the best solution both for engines with head in aluminum and cast iron block, both for engines with aluminum head and aluminum block. – Each slat is sheared with an ultima laser generation that guarantees perfect quality of the cut while the reliefs are printed with a optimal stabilization process. GAS STOPPER Gas Stopper technology is a key factor in the design of multi-lamellar gaskets. The stainless steel slat is folded back on itself around the cylinder hole ensuring a perfect seal even at high pressures. The Gas Stopper works around the combustion chamber to allow the cylinder head and engine block to tighten even more tightly and thus prevent gas outlets. BENEFITS – High sealing properties in high conditions compression; – Greater elasticity and constant load resistance; – Optimized load balancing; – Better engine performance; – Greater duration over time. BENDING RADIUS OPTIMIZED The process of forming the reliefs is a unique system which optimizes the bending radius in order to increase sealing in critical areas. In particular: – Increases the conformability of the gasket reducing stress points; – Improves the grip of the contact area of the pads between the engine block and the surface of the cylinder heads. TREATMENT THERMAL OF RELAXATION All reeds of the head gaskets are subjected to a process of relaxation to significantly reduce the voltage induced during the realization of the surveys. Unlike others, Athena Pre-Coated Metals endure perfectly this type of treatment. The main benefits are: – Reduction of hardness and brittleness; – Greater flexibility and resistance to deformation; – Easing of tension points after the process relief formation; – Stabilization of the seal which allows a reduction of stress in the cylinder bore; – Increased resistance to combustion around the cylinder (pad profile) to withstand high pressures. TECHNOLOGY OF COATING EXCLUSIVE The coating on both sides of the outer slats comes applied after the stress relieving process, to ensure uniform coverage and thus avoid any type breaking. This process, which takes place in two phases, ensures excellent sealing to refrigerant fluids ed motor oils and responds to any need you may have can occur in different hostile environments. – The first layer of the coating is resistant to high temperatures temperatures and allows you to minimize the Irregularities in the surface of the engine block and the cylinder head; – The second layer is a silicone-based compound which avoids sticking of the gasket during the engine disassembly. GASKETS MLS - MLS PRODUCTION PROCESS 1. LASER PROCESS A state of the art laser allows for high cutting gasket definition. For specific materials reinforced internal machinery is used die cutting. 2. RELIEF STAMPING Every single slat is worked to obtain the formation of reliefs according to the technical drawing of Athena which ensures the seal to liquids and gases of combustion. 3. RIVET ASSEMBLY Each individual slat is assembled and fixed with of the rivets to ensure optimal alignment of the layers. 4. FINISH The application of different treatments to the surface allows the gasket to have a better performance by preventing any phenomenon of adherence and ensuring resistance to high temperatures. FEM TEST- The FEM (Finite Element Method) test allows you to create a wide range of simulation options for control the complexity of both modeling and analysis of the system, displaying stiffness and strength. The FEM test also allows a detailed view of the points where structures bend or distort and indicates the distribution of stress and displacement centers. GENERAL NOTES OF INSTALLATION - ATTENTION: For the preparation of the engine, it should be noted that the diameter of the gasket must be greater than to the bore. In particular, the diameter of the gasket must be +0.5 to +1mm wider than the bore. For example if the bore measures 86mm, it is recommended to use a gasket with diameter from 86,5mm to 87mm. This is a general indication which in any case does not replace the opinion of your trainer. INSTALLATION PHASES 1. Thoroughly clean and degrease the engine block and the contact surfaces of the cylinder head. 2. Check the flatness and finish of the surfaces of contact. TO GET A GOOD HOLD IT'S A LOT IMPORTANT TO RESPECT THE ABOVE SPECIFICATIONS. If the contact surfaces exceed the tolerances indicated, the height of the head or the cylinder head needs to be adjusted by a qualified mechanic. Excessive tillage will have consequences on the compression ratio, piston clearance / valve and camshaft timing in engines with overhead camshaft. For this reason they must observe the engine manufacturer's restrictions in this respect to the thickness of the cylinder head. 3. Clean all traces of dirt, oil and corrosion from the bores bolts present in the block. IT IS IMPORTANT THAT THESE THREADS ARE CLEAN, OTHERWISE YOU WILL NOT GET THE CORRECT TIGHTENING, WHICH WILL CONSEQUENTLY LEAD TO A GASKET MALFUNCTION. 4. Lightly lubricate cylinder head screws/bolts e tighten them completely by hand by inserting them into the engine block. Using a steel ruler, measure the height of the screw bolt coming out of the block. All measures should have the same length (unless you use screws bolts of different lengths). A longer length it may mean that the threads are not clean. Inspect the threads and clean again if necessary, in order to equal the lengths of all studs/bolts. IF THIS OPERATION IS NOT CARRIED OUT, THE MATCH OF THE THREADS OF THE SCREWS/BOLTS DOES NOT WILL BE CORRECTED AND THIS COULD CAUSE DAMAGE TO THE LOCK DURING TIGHTENING OR TO THE ENGINE WORKING. After checking the inserted length, remove screws/ bolts and clean them. 5. Check that the sealing surfaces and threads are clean, dry, free from debris/burrs and are free from sharp edges. If cylinder head bolts are used, they must be installed according to the manufacturer's instructions. Center the racing gasket on the block making sure not to scratch its coating. 6. Gently lower the cylinder head onto the block, making sure that debris does not fall on the gasket and that its coating will not scratch. 7. Fit the nuts/bolts following the manufacturer's instructions. Pay attention to the lubrication instructions provided as well as to torques and tightening sequences. OTHERWISE IT WOULD PREVENT THE SCREW / BOLT TO REACH FULL PRELOAD, CAUSING A MALFUNCTION OF THE GASKET. WE ALWAYS RECOMMEND THE USE OF NEW BOLTS AT EVERY HEAD DISASSEMBLY/ASSEMBLY. 8. Reassemble all other components, top up engine oil and refrigeration systems. Check that there are no leaks and, if so, check the cause. 9. Start the engine and wait for it to warm up of use. Check for leaks. Then, stop the engine, let it cool down and check the cause. 10. If no leaks are found after the warm-up phase, it may be necessary to re-tighten the screws/bolts of the cylinder head. Consult the manufacturer's instructions. TECHNICAL SPECIFICATIONS The sealing surfaces must be free from scratches, scuffs, localized corrosion or cracks, as these can cause a loss. For finishing sealing surfaces to be rectified, respect the following maximum values: Rz 11μm - Rmax 15μm - Wt 8 -10μm . The values can be measured with a finish probe superficial like a “Mitutoyo Surftest” roughness tester. The Ra values given below are nearly equivalent to the values above and are obtained with machines such as Rottler, Robbi, Serdi, etc.: Ra 0.8 μm for vertical machining (with cutting tips). Ra 1.6 μm for surface grinding. These values refer to use on finished surfaces comparable to that produced by Flexbar. MAXIMUM DEFORMATION VALUES Using a level ruler and feeler gauges, the distance maximum in the longitudinal direction is: For a length of 100 mm, maximum 0.03 mm - For a length of 400 mm, maximum 0.05 mm - The maximum distance in the transverse direction for a length of 100mm is 0.03mm. IN GENERAL, IT IS BETTER TO TRY TO GET SEALING SURFACES AS FLAT AS POSSIBLE, FOR GUARANTEE THE MAXIMUM HERMETICITY OF THE RACING GASKET. NB: the codes starting with 338 refer to the gaskets MLS, those starting with 330 to Cut Ring gaskets.
