Hi everyone,
This morning on startup the Crankshaft Pulley has sheared and thrown the accessory belt ! The engine runs perfectly but no power steering, Air con or alternator.
my Local 4X4 garage say they can fix it but their only free slot is 2 weeks time and also I need to get and pay for transport to get it there.
Looking at it there is a single bolt holding it in place and looking on eBay lots of second hand and new pulleys are available so me thinks easy job undo the bolt pull off the sheared shaft and fit replacement
BUT after reading the Haynes manual it talks about removing the starter motor, lock the flywheel then undo the bolt etc
HELP please ?

Unfortunately it's not a simple job, or a quick one.

Although the pulley is only secured by a single bolt, the timing belt pulley is also held in the timing location by the crush of the bolt.
So what looks like an easy job, becomes much more difficult, requiring the crankshaft be locked in the timing position, as does the camshaft. The starter needs removing to fit a flywheel locking plate, to prevent the crankshaft from rotating, while the bolt is removed.
Also the bolt can stick in absolutely solid. I've just done a top end rebuild on mine, and the bolt which I only fitted a year ago was stuck fast, requiring me to use a 4ft extension on my breaker bar, so it's not a job for the faint hearted, not to mention that you need the timing tools, a new pulley (there are 2 types), and a new bolt.
