bmw e46 320d crank pulley replacement

Ok guys – this is a common issue affecting all diesel cars, not just bmw.

Its simply down to the crank pulley rubber material perishing with age.

Here’s the Car in question, a lovely Imola Red Coupe.

Here’s the crank pulley that has broken up, the belt didn’t fail which is very lucky.

To replace this pulley you’ll need a very long breaker bar to loosen the crank pulley. This is extremely tight.

You’ll also need the BMW flywheel locking tool to stop the engine rotating.

Using a ‘drill bit’ is NOT recommended.
