Firstly, you need to remove the 22mm bolt and spacer securing the pulley to the crankshaft. Then refit the bolt minus the spacer.
To make up a puller, I used two 8mm bolts and the bracket from an exhaust clamp.
It's best to use two equal length 8mm bolts but these worked for me just the same.
Fit the two bolts through the exhaust clamp bracket into the pulley holes by several turns to ensure a secure fit.
By backing out the pulley bolt which pushes against the clamp bracket, the pulley slowly but surely pulls itself out with ease.
