wots the best way to undo the the crank bolt that holds the pully on. cheers lads,

 

On me cos I put it in first gear and then used a long breaker bar, after removing hoses to i/cooler so I could get a big enough range of movement, undone no problem.

Wedge a hammer handle in the bottom end somehow :x

 

Either put the car in 5th gear with the handbrake yanked up, or remove the starter and use a screwdriver to wedge the ring gear while undoing the bolt.

If your doing a cam belt change and u choose the in gear method remember to fully time the belt and tension it back up before tightening the bottom pulley bolt!
