In the distant 2011 already, I personally changed my 850th timing, the source of information for me then was basically, the site
I did this for this article:
In principle, a similar sequence of actions is described in VADIS, but as my case showed, for proper installation of the belt this information may not be enough (especially if the camshaft pulleys were removed, for example, to replace the stuffing box). If you look at the removed pulley, it does not have a fixed position on the camshaft, but can be adjusted in a fairly wide range and tightened with screws.

Thus, the marks on the camshaft pulleys that need to be aligned with the cutouts on the lid serve only as a guide to approximately catch the correct position of the camshaft with an error of + -2 … 3 teeth!
Correctly, the shafts are placed on the slots on their opposite side.
To check, you need to remove the transmitter and the transmitter of the transmitter.
If the belt is right, it looks like the photo below.
When the mark on the crankshaft gear coincides with the mark on the oil pump:

The slots of both shafts are parallel to the plane of the head:

I recommend to anyone who doubts to check it out.

A little lyrical digression.
In my case, the belt was wrong for 1-2 teeth and I was rolling like this from the very moment of purchase. And today I finally finished my small prophylaxis, which lasted almost a week (replaced: hydrics, camshaft oil seals, timing, timing belt, rollers, pump, front crankshaft oil seal, went to Lukoil Genesis 5w40). I put the timing on the right article. Once again I checked everything and started it.
The new hydricks a little rushed and the engine growled like a full-bodied cat. Then it was even more interesting. To say that the test trip surprised me — not the right word, I had a break in the template! The car never rode like this, a herd of Swedish elks woke up in it (they would not have smashed everything there under the hood)! Now I understand why 850 is called a dynamic car.

Well, now it's constructive.
To properly put the belt — the shafts need to be fixed.
To fix the camshafts, there is a special tool VOLVO 9995452.
You can grind and carve something like this, like here (from XC90, we may not have the dimensions, you need to check):
But you can make it easier.
In the Leroy Merlen hardware department we buy 4 plates mm, two , suitable cogs and wide washers In the amount of rubles per 200).
We master something similar to this:

Slots on the shafts with a displacement from the center, by inserting washers, we select a suitable offset.

The width of the groove is 4.28mm, and the thickness of the packet of two 4mm plates, inserted between them a strip of plastic bottle, it turned out just right.

Slightly grabbed the clamp by the master cylinder.

Then everything is simple:
Fixed the shafts;
He threw the timing;
I released six bolts on the pulleys of the camshafts;
He took out a check from the tensioner (do not forget to put a plastic stopper on it, then do not slip it);
Strongly pressed the strap two times on top, twice on the left;
Tightened 6 bolts on the pulleys with a torque of 20 N m.

First start of engine:

I hope the information will be useful, to all successful repairs and impressive results.
