3.0 TDi BKS Injector pump belt and camshaft seal change

My 2006 3.0 V6 TDi BKS engine needs the LH camshaft seal replaced and the fuel pump belt.
Can't find any procedures, pulley tension spec. or fastener torque specs here on the site.
If I have it right, the pump belt is not timed to the camshaft.

The camshaft seal has failed and the belt is contaminated with oil.

I have purchased a new tensioner, belt and seal (genuine, $ ouch), ready to do the job.

From what I can see, from left to right facing the engine, there is a 21mm nut (pump), 13mm bolt (tensioner) and 24mm nut (camshaft). These are fastener head sizes.
There are holes in both pulleys to support a holder for removal and replacement, 10mm on pump and 12mm on camshaft pulley.
The PCD are both 65mm, allowing one tool to be fabricated.

Could someone please provide the torque figues and perhaps a procedure, please?
I'm located in Australia, posted this initially in the Au/NZ Community Section.

Any help would be appreciated. Will likely write up the procedure iwth pics, there are some Touaregs out there with decent miles up, mine is 166ks.
Belt was due for inspection at 180ks, but seems there is no replacement at service intervals.

Thanks, as a new owner I look forward to participating in the community.

For those unfamiliar with the belt here are some images.
It is the common rail fuel pressure pump run by a belt to the LH camshaft on the BKS engine.

Belt removal requires the removal of either the black plastic intake distributor or the pump pulley. There is precious little space between the intake distributor and the pulley.

The belt, inner cover and surrounding areas were coated in oil/dust which I cleaned prior to the pics.

Look forward to someone being able to advise the info required.

cheers,
richard

Champion job zagg, thanks mate.

Considerably different to the >2007, in a number of ways, the pump pulley and the addition of an idler roller particularly.
The torque settings are there, which is important and the procedure, at least for the later engine.
Now a matter of working out the difference between the engines, if there is one.

I am hoping the removal of the pulley wheels on the earlier BKS doesn't involve a puller, as I can see no threads in the pump pulley.

Now that the area has been cleaned thoroughly I can gauge the extent of the seal leak.

Here is a link to the page.
