Drive/aux belt will not go on

Nightmare with 147 1/9 jtd lusso (2003). Wife came home with no power steering - found aux belt trailing on ground.
Got the correct part (gates 6pk1835xq) from parts dealer but it will not go on. I rotate the spring adjuster to the max but still the belt is too short to go on. Re-checked with parts dealer but he is sure it is right one - my checks seem to bear this out (although one supplier on ebay says it is incompatible it seems to be a one-off).
The old belt seems to be 1.5 to 2 cm longer but it is very old.
Gave up today but must try again tomorrow. Any ideas? I am at a complete dead end.

If you old belt that fitted is longer than your new belt that wont fit then you have the wrong belt, they will stretch slightly but nothing like 2cm

use the number on the old belt. 6pk means 6 ribs. The number after pk is the length.

There is no number on the old belt - just bare rubber. No help at all. After that all I can do is go for a bigger belt - yet all of the longer belts for sale say they are incompatible with this model. But it seems mad that before the tension wheel is even brought into play there would be so much tension needed.
I can think of no other way than what you suggest.

Ive come across this problem before and sometimes a pulley wheel may have been changed that is a different size or the spring loaded tensioner wheel is a different size so the belt listed for the car is a different belt to the one fitted. Firstly eurocarparts can look up the correct belt size and then offer you one of a different length.Secondly the 2.4 jtd has an adjustment wheel as well as the spring loaded tensioner whilst ive previously changed numerous 147 jtd belts i cant remember if it also has an adjustable wheel.

I had a look but I am pretty sure there is no further adjustment wheel anywhere - just a spring loaded tensioner. Anyway, I have a disc problem in my neck and its giving me hell now after hauling at that sucker. I have bought an 1840 today which I will try tomorrow with an able bodied helper. I have never known that putting on a fan belt could be so hard and I have fitted many over the years.
I'll report back on the outcome.

OK. here is how it went - even with help and an 1840 belt it didn't want to go on. Most advice I could glean said the spring adjuster needs to go the whole way (needs some force) using a 15mm ring spanner. This didn't get me close as the belt, even with rotating the crank, always wanted to spring off.
But then it came together...3 people required.
Put fan belt on correctly but leave it off the alternator pulley at top of engine - this is the easiest to access.
Strongest person on the spring adjuster with 15mm socket (ring spanner didn't work for us).
Least clever of remaining two people holding a socket spanner to the crankshaft pulley
Cleverest (guess which one I was) person stands at side of bonnet to guide on the belt.
Strong person pushes adjuster full way and shouts to less clever person who rotates the crankshaft pulley steadily. Clever person rotates belt onto alternator pulley. And takes all the credit.
Carry on rotating crankshaft pulley until you are certain it is not running off-centre anywhere.
Then have a cup of tea.
