why remove the main bolt on the crankshaft?
what is the purpose of removing the main (left hand thread) bolt on the crankshaft when changing the timing / balance belts? in this doc..

it says that you need to remove the bolt. but in the alfa document that I have for the process..(see here.. http://www.cloverleaf4.co.uk/tech.html) it does not mention it :(
does anyone have a complete copy of the "vehicle characteristics and maintenance guide" that this is taken from?
so - crank bolt out or not - and why?
**** quote from further back in this post ***
.....
Have now corrected the timing. It was one tooth out on the crank. I reckon yours would have been a tooth out in the other direction as I had less low down torque.
Anyway, it is now driving as expected power wise but I really think it does need a balancer belt as at mid to righ revs it doesnt feel right and its a bit noisier. In no rush to do it as its running well enough for the moment.
The biggest problem I have is that the bottom crank bolt will not budge! Even with our nice big new compressor its not touching it. I think the air hammer might be a bit weak though.

The bottom pulley is held on by a left hand threaded bolt so you've probably been tightening it up.
