Lightweight flywheel for Volkswagen Golf 3 4 / Audi A3 8L / Skoda 1.9 TDI 2WD 5-speed gearbox 02A 02J

This lightened and reinforced High Performance flywheel from STR Performance , significantly optimizes engine revolutions as well as the distribution of weight between the front and rear of the crankshaft in terms of inertia on Volkswagen Golf 3 4 Bora engines. / Audi A3 8L / Skoda Fabia 1.9 TDI 90hp 110hp 2 wheel drive 5-speed gearbox 02J 02A 228mm

Only compatible for 1.9 TDI 90hp 110hp transverse engine (not compatible audi A4 B5, A6) 5-speed gearbox 02A 02J clutch 228mm

Benefits of our lightweight single-mass flywheel:

• our steering wheel weighs only 4.6 kg, the original steering wheel 9 kg
• all our flywheels are made of chrome molybdenum steel G 1.75, extremely suitable for high speed engines
• homologated without limitation of CV
• significantly improved acceleration due to less flywheel mass
• the engine revs up faster, no loss of performance.
• suitable for motorsport and production vehicles
• less fuel consumption
• reduces response lag typical of turbo engines
• precision balancing, bearings are less affected, fine balanced according to DIN ISO 1940
• including starter crown
• compatible with both a standard clutch and a high performance clutch
• made in germany
• integrated release crown

Here are the assembly instructions:

Preparation :

The friction surface of the flywheel, the threads of the crankshaft, the crankshaft screws (only if these do not have a threadlocker) and the clutch screws must be cleaned of grease, dirt and grease. dust with a cleaner (e.g. brake cleaner), otherwise the clutch may slip after installation.

Screws with thread lock must be used with "medium strength" loctite.

Flywheel screws:

• Make sure they are screwed tightly into the thread.
• First tighten by hand then tighten evenly "crosswise" to 116Nm with a torque wrench.
• (1st pass about 65 Nm - 2nd pass 116 Nm)
• The friction surfaces (organic and sintered) are equipped with a "spring cage".
• In order not to impair the operation of the clutch, the friction disc must be fitted with the side of the spring cage facing the flywheel.
• The friction disc is centered on the flywheel using a centering mandrel (not supplied).
• Then the pressure plate is pressed onto the flywheel spindles and screwed on.
• It is important to ensure that the friction disc is centered if no centering mandrel is available for mounting.
• Screw the pressure plate with the cleaned screws
