Having managed to get home with no power steering and no charge or water pump I discovered that the fanbelt had not broken but the crankshaft pulley had disintegrated into two parts . How do I remove the old one and replace it?

I hope you didn't drive it very far with no water pump  A recipe for over heating and possibly warping heads.

The pulley outer is held to the inner by half a dozen M8 Torx headed bolts. Undo & replace  Bear in mind that they are not all equally spaced 

And welcome to the forum

As Andy said ... but if you can "see" its in 2 parts. then they are both there, so probably the torx bolts just need tightening up   providing they are ALL still there ......

It's not quite like Nige. The bit that un-bolts is actually two bits bonded together with rubber ...... harmonic damper  The rubber bit on kaseytea's has expired

hi thanks for replies and no I didnt overheat it I was watching temp guage all the way. However the pulley is made up of two rings with a rubber "damper" in between rubber has degraded and sheared leaving me with outer ring and inner ring no longer connected. Pulley is fixed to cam shaft with 1 large central bolt which is torqued to 150nm plus any ideas on how to remove it

Nope pulley is attached by the six bolts around the centre bolt

Leave the centre bolt well alone

[05omegav6]

To add, if all six smaller bolts are out, use a bigger hammer

As above and TaxiAl says, the outer pulley bit is held by 6 bolts to the pulley's inner.

The crank pulley is two pieces...

1. The auxbelt pulley/harmonic balancer. The broken bit on yours, which attaches with six bolts to...

2. The cambelt crank pulley which is attached to the crank with the big single bolt.

Just to be clear

Err... Engine size?

Does it matter?

I assumed V6. Are the 4 pot petrol, 6 cylinder BMW diesel and 4 cylinder GM diesel the same?

[kaseytea]

Hi thanks for response. I cannot find any other bolts at all . The engine is a 2.2 dti ecotec It sure looks that only one bolt secures

[05omegav6]

It would seem so I too had assumed a v6

[05omegav6]

If you can only see one bolt, then there's only one bolt

Pop the car in first and make sure that the hand brake is fully on, then attack it with a long breaker bar
