Hi rg,
Steady on, thats how chinese whispers start wars

. It took me about 1hr 50m to change the belt and reassemble all the removed components i.e. wheels back on the ground. Its not that bad of a job really. The part which will frighten most people is the timing. However, the book of lies actually covers it very well. The pain part of the job is that the belt is wound around the engine mount. Without this aspect you could probably change the belt in half the time.
One word of caution though. Mark the positions of the engine mount and stay bar with marker paint so that you can put them back in the same place. I've never understood how to set the stay bar arrangement correctly.
The plastic container for the ECU's does have to come off the car simply to afford access to the dozen or so 10mm bolts retaining the plastic timing belt cover.
The bolt in the middle of the crank pulley does not have to be removed. Removing the four bolts around the perimeter of the pulley is all that is required.
I looked at the balancer shaft belts all three times when I've replaced the cam belt. In all cases the belts looked brand new so I decided to leave them alone. To replace them is a little more work with a little more dismantling but is perfectly possible. I think you need to take a view when you see them. However, if you view them first and then decide to change them then the car is off the road a few more days until you can source new belts.
I haven't got time right now to write up the sequence but I could if you'd find it useful. No promises on time though.
cheers
