flywheel locking hole

[pug306driver]

Thanks for all the replies, need to find the hole for when its cam belt time ( pun ) .

Also the engine steady affair at the rear of the engine, the big round one.......the round bush bolt is easy to remove by the looks, but does the vertical bolt at the other end of the "steady" come out without taking the "air pipe" the black plastic looking affair above the vertical bolt??

Its fitted the correct way at the moment, ie, self locking nut at the bottom.
