An easy tip regarding the waterpump pulley, put a couple of drops of superglue on the back of it before you put it on the water pump, fit, it to the waterpump and leave it for a couple of minutes (have a beer) and then its alot easier to put the bolts back in without the pulley falling off every 10 seconds. A long handle 10 mm ring spanner with a slight offset is a handy tool for this also (and magnetise the sucker).
All good tips..if i had dramas i was going to head down this track and glue them together.
If you do,use Loctite 406..best glue available.
