I reckon...
T=5+11+6
B=12+3+5+2
A=12+ (9 or 13) +10
I thought 12 was the PAS??? Is it the aircon? SGR41208 is the PAS pump.

(Top pic) belt #12 goes between the aircon and PAS. The PAS pump is relayed through the aircon pump. If that makes sense.
For the timing belt isn't #6 the drive pulley from the crank? If so don't think you need to change it. 11+5
For the balance belt I think 12+3

Yes it does, that's what I thought was going on. So why 9 or 13 (or am I being thick?).
Yes, you're right
Number five looks like it has a bearing (6)...is it not critical?
Thankfully I got the balancer belt and idler cheap on ebay as they're about ?115 for the pair!!!

Have you ever touhgt that this belt is too thin? Here in Finland, we have lot of problem, how long this timing belt last. My last original timing belt has only 30 000 km and I lost 4 valves. The timing belt doen?t snap, it loose it?s thoots. Before that my timing belt last 18 000 km.
Now I changed that belt and but 1" belt in. We have in Finland custom made 1" belt, which have two adjustable camshaft pulleys , couple of extra parts, which you need to install this belt,
See that last picture of this site http://www.heikka.fi/hihnapyorat.html
And if you change your belt allways change your waterpump, because you can?t take it off without taking out the timing belt.
I take off my balancer shaft belt, because of that 1" timing belt. It don?t fit anymore, because 1" belt take so much space.

No changes, Just take out balancer shafts pulleys and ready to drive.
I have to also tell you, that I can?t drive my car now(clutch, flywheel etc.), but I will tell you more later, how the car runs without that balancer belt.
I think he mean't just remove the pulleys on the end of the balance shafts. If you remove the shafts you have to plug up their oil feeds.
I've heard people do this before with no noticeable increase in vibration, but also no performance gain either (or minimal) But I didn't realise you needed to do it to fit the 1" belt.

Lead follow or get the flock out of the way
Hope I can explain that to all.
No need to make extra caps. Only take off that belt and the pulleys. Let them be there, no harm. Just a little bit safer engine.
No horsepower on my mind, when we take that belt off.
When you put that 1" belt the distance between cam pulleys and beltwheel? ( that part which is lowest part in the way of belt) is not the same as original.And I mean the distance between cam pulleys and engine. So you have only 2-3 mm distance between 1" belt and balancer shaft pulley.(the first one, when you look your engine forward). Manufacturer recommended that, that pulley will be taken off. It is hard to explain and I don`t have any pictures. Sorry.
This set costs little bit over 400 € and it is full set. The belt is from fiat ducato 1.9 diesel engine. I don?t know where the beltwheel? is from, but it?s ordered from factory of fiat, so it will be genuine original part also. The rest are custom made parts. Manufacturer of this set recommended that same 60 000 km as Alfa Romeo, but as you all know that 60 tkm is a little bit too much for that original belt.
When I get my engine and clutch ready I will make some test drives and tell you better feelings of the car. Hope I get also few extra horsepowers also
Anyone managed to figure out the 9 or 13 issue in picture three?

Errrm, what am I missing?
13 - crank pulley drives the aircon pump.
9 - air con pulley drives the PS pump...
Although in the second diagram of pic 3, there is a wierd drawing of the air con pump pulley - only shows one drive area on it...
EDIT - JUST REALISED MULTIPLE PART NUMBERS - CONFUSED X2 HERE!

Il guess that the top diagram is for cars with AC and the bottom one is for those without - although I thought the all had AC as standard...

For Balancer is 12 + 5 + 3
5 and 3 are bearings and will be good to change them.
They are not from balancer shafts. One is for the balancer belt tensioner, and the other changes direction of the timing belt.
Thanks everyone....think we got there in the end
