Removing crankshaft pulley without crankshaft pulley removing tool!

Hi all. New member looking for some advice.

The rubber in the crankshaft pulley on my e46 320cd split and the outer rimmed circles sheared off. The crankshaft pulley is obviously still attached by the large bolt.

Is it easy to remove this without a crankshaft pulley removal tool, the one that fits around the teeth to stop them moving when wrenching the bolt off?

Also i tried to wrench off the bolt and the whole crankshaft moved a few cm's. I presume this wont have any effect on the timing??

Thanks for any info.

No effect, get a big breaker bar and take it off. It's reverse threaded if I remember correctly.

Not sure about the 320, but the 325 and 330 are not reverse threaded. Although, it looks to be a different design, so I can't say for sure.

Thanks guys. So if i have ye right all i need to do is put a breaker bar onto the bolt and give it a whack with a hammer clockwise to release it. Once changed how would i go about tightening the bolt up to the correct torque with only a socket set. Thanks in advance.

Anybody got any ideas?

I just checked, it's not reverse threaded.

Take a big breaker bar, have somebody in the car press the brakes (cause you will turn the whole engine before that bolt moves) put it in gear and then spin it

Ahh very good. You sure yeah?

Its a UK import 2004 320cd (diesel)

Its automatic as well so will "pressing the brake" trick work, seeing as i cannot put it into gear??

Thanks.

Pull the radiator and try a impact wrench... Squirt some penetrating oil onto the threads... There is always the old trick of heating it up with a torch then the imact wrench, but I don't know if there are any rubber seals there that may be damaged.

Looks like there is a "castle nut" around it, See if you can wedge a long (lever) bar between the teeth to hold it and then hit the center bolt with the impact wrench or other long wrench with breaker bar.

Could also try sticking a rod/bar through the holes in the back of the pulley and see if you can hook it around/under part of the block to hold it while you turn the bolt with a BFR. Be careful not to pinch anything when doing this.

Right hand thread

I put mine in 6th, applied the brake with a lump of wood and used a 3/4 drive socket wrench and a length of scaffold pipe. it gave in eventually but I had to use the socket wrench ratchet to maximise the load applied. Definitely Normal Right hand thread on my E46 320D so anti-clockwise to undo.
