What the flywheel does here
On a manual car the flywheel carries the clutch. On most modern BMW diesels and many petrols it is a dual-mass flywheel, two masses with springs between them. On an automatic the flexplate and the torque converter do that job instead.
Bavarian Engines Store does not hide a flywheel in the engine price. If you need one, it has to be in the order.
When to replace it
If the clutch is slipping, if there is a rattle at idle that disappears when you press the pedal, or if the dual-mass unit rocks too far by hand, replace it while the engine is out. The labour is the engine removal. Paying it twice is the expensive choice.
A solid flywheel conversion is a workshop decision. It changes the clutch and sometimes the starter. It is not something we do quietly inside a used-engine listing.
Match the engine and the gearbox
Bolt pattern, starter ring and clutch spline have to match the gearbox you are keeping. A petrol flywheel on a diesel, or a dual-mass unit from a different code, may bolt up and still be wrong.
Automatic cars: the torque converter must sit fully home on the pump before the gearbox is bolted. A converter left proud destroys the pump on first start.
Bolts
Flywheel bolts are stretch bolts on many BMWs. Use new ones and the workshop's torque and angle. Old bolts are a common cause of a knock that sounds like a bearing.
Lock the crank the way the repair instructions say. Do not hold the crank with a screwdriver in the ring gear.
Ordering
Tell us manual or automatic and the gearbox code if you have it. We will not guess a flywheel from the engine title alone.
Warranty on the engine does not cover a flywheel you reused.
Warranty
Many engines come with up to 12 months warranty. A proper workshop must fit the engine. The warranty is for a fault inside the engine. It does not cover the wrong engine, a dry start, the wrong oil, or damage done after you open the crate.
Shipping
Crate shipping from Hamburg costs 299 EUR. We pack the engine in a strong crate and send it to the address on your order. You need a forklift or an engine crane to unload it.
FAQ
Is the flywheel included with the engine?

Should I always replace the dual-mass flywheel?
If it rattles, rocks too far or the clutch is out, yes, while the engine is out.

They have a flexplate and a torque converter. Both have to match.

Yes. Crate shipping from Hamburg costs 299 EUR to the address on your order.

Up to 12 months on many engines, for a fault inside the engine, after a proper fit. See the warranty page for the full rules.
