98 UK spec turbo
How does the bottom pulley attach to the gear train ? I know it's bolted through - how long is the bolt and to what is it bolted ? I ask because it appears that the bolt has either sheared or come off - the gear where it bolts to is unthreaded as far back as I can see so I hope I've just lost the bolt rather than it being sheared off in the block. How far back does the thread start ?
Also - is the bolt available as a part number or does anyone know the size of the replacement ?
thanks for any help

The "Crank" Pulley is held against the main drive gear for the timing belt,if this has been lost, be careful as only a woodruff key is holding the main drive gear onto the engine.

The part number for the bolt is 12369AA011

Suggest you dont run the engine untill it is replaced and correctly tightened.

It is unusual to loose this particular bolt, so would advise checking that it has not "sheared off" as it does thread into the front of the crankshaft, unless it was not correctly tightened after a timing belt change and left loose.

Thanks - I'm not running the engine until I can get the replacement bolt and see exactly what's up. Hopefully it will have just come loose otherwise it will have to be tapped out.
