Locking the flywheel/crankshaft

[geoff]

Not sure what year a later MK2 is but on my '07 hdi I always disconnect the flexi joint to get better access, a quick and easy solution.

Locking pin - can be a nuisance, on mine I ground / filed a decent chamfer on the end of the pin which helps a lot.

You will definitely need to pin the pump for the belt installation.  

Cannot see ?  just jack up the engine a bit higher to get a better view.

Early six segment pulleys pin at 5 o clock position
Later three segment pulleys pin at 12 o clock postion

Try a chamfer on the pump locking pin for ease of entry / helps to find the position as the pulley starts moving over the hole.

Having difficulty .... always good to stop for half an hour for a cuppa and a sit down as you'll come back refreshed and usually the job simply gets done without any fuss. .... Lol !
