Hello There:
First, after removing the crankshaft bolt the pulley will come off no problem. Next, there are four (4) 10mm bolts that need to be removed. You will need a gear puller, at least I did, to remove the balance shaft drive gear and then the cam drive gear behind it. Be careful not to loose the key on the crankshaft.
Good luck with that!
Exitwound is correct; you will need to remove these to be able to do the job such as change belts and change out your seals.
Hope this helps.
