- ✓ lightens 6.6 kg
Lightened high-strength chrome molybdenum flywheel with starter ring, suitable for all M50 engines,
installed in:
- BMW 5er 520i 24V, 525i 24V, 525iX 24V ( E34 )
- BMW 5er Touring 520i, 525i, 525ix ( E34 )

Is replaced against the original flywheel, reference :
1223540, 1223596, 21211223540
The original clutch (228mm) is usable, reference : 21211223545
The screws have to be taken over by the M20 engine because the original ones are too long.
Below in the matching accessories you will find the required Sachs Performance clutch pressure plate. You can also choose between the appropriate organic or racing Sachs Performance clutch disc.
Advantages of our lightened single mass flywheel:
- our flywheel weighs only 6,6 kg, the standard wheel over 12.0 kg
- all our flywheels are made of chrome moly steel with quality G 1.75, extremely suitable for high-speed motors
- recognized for unlimited HP
- significantly better acceleration due to less inertia
- the engine runs faster, no loss of performance.
- suitable for motorsports, racing or serial vehicles
- lower fuel consumption
- significant reduction of the turbo lag
- precision balancing, bearings are less affected, finely balanced according to DIN ISO 1940
- including ring gear
- suitable for either a standard clutch or a high-performance clutch
- Our flywheels are registration-free as they have no direct effect on the actual performance.
Delivery:
- 1x lightened high-strength flywheel made of chrome molybdenum for all M50 engines from BMW E36, E34
- Installation instructions
Our lightened flywheels are registration-free and therefore do not need to be registered.

Saubere Verarbeitung. Top Preis.

Verarbeitungsqualität des Schwungrades war nach Sichtprüfung sehr gut. Einziger Mehraufwand war das kürzen der M8 Schrauben auf 13mm länge. Zusammen mit einem original Sachs Kupplungssatz ist das Schwungrad nun die ersten 150km gelaufen. Ohne Probleme. Würde den Kauf erneut machen.

Top Ware - vollkommen OK. Eine Kleinigkeit: Die Löcher der Schrauben für die Befestigung der Druckplatte sollten komplett durch das Schwungrad gebohrt werden - denn so sind die mitgelieferten Schrauben zur Befestigung der Druckplatte zu lang.

Passt wie beschrieben mit den Schrauben vom m20 auf den m50 Motor. Die Passbohrung könnte etwas sauberer gebohrt sein aber ansonsten Top! Der Motor ist deutlich drehfreudiger. Würde ich jederzeit wieder machen. Kuppeln lässt sich alles wie Original weder stärkere Vibrationen noch ruckeln oder Ähnliches.

- Which screws can be used?
The original bolts can be reinstalled.
- Which clutch can be used with the Epytec flywheels?
You can continue to use the original clutch or an identical Sport / Performance clutch. Please check with the clutch manufacturer whether these are of the same design as the originals. If this is the case, then it will also fit 100%
- What is the friction coefficient of the flywheel?
In principle, the friction coefficient can be assumed to be at least the same as that of the original cast disc. Due to the higher alloyed steel, our pulleys are slightly better than the original cast pulley. Of course, the material of the friction disk also has a major influence here; this must be checked with the manufacturer of the friction disk
- What material are the flywheels made of?
The flywheel is made of 16MnCr (chromium molybdenum) steel, which means it has a density of 7.76 kg/dm³
- Does the flywheel have a TDC marking and other markings for the ignition?
The flywheel has no TDC marking, only the pin on the back, just like the original flywheel. Tip: To adopt the TDC marking, the original flywheel must be turned to the TDC point before disassembly and the new flywheel must be marked in exactly this position.
- Does the flywheel have the default unbalance or is it balanced to zero?
The flywheel is supplied with the default unbalance. Unbalance can be created as follows! We first balance the pulley to 0, then apply a test mass at the specified point, which corresponds exactly to the unbalance. The pulley is then balanced to 0 again with the test mass. If you now remove the test mass, you have exactly the specified unbalance.
- Do we only sell the ring gear / gearwheel of the flywheels?
No, we can only sell the flywheels complete.
- Why do I have to run in my clutch?
The principle of a clutch is similar to that of a brake system. The different materials / surfaces must first adapt to each other. This happens through friction. With standard clutches or organic linings, this happens relatively quickly, as the lining material is "softer" than with sintered metal linings.
