No pump timing needed. Chain yes definitely.

Why do you want a new HP pump?  Rare (if ever) that they fail.

Actually Iam going to change the chain! And the pump seems old and rusty so Iam thinking about changing it. But how do i get the pump wheel of? I don’t have that special tool

  Have you tried prayer yet?

If that doesn't work: 1. you could buy or borrow a special tool. 
                               2.  make one yourself.

Prayer?

i dont know where to buy or borrow it.....

have an idea how to make on my self ?

Prayer -as in pray.
Might be better off just doing the chain as originally planned.
Wouldn't want to have a failure at removal and "F"it and be totally screwed.

But in order to change top and bottom chain. I need the dismount the wheel on the high pressure pump....otherwise I can’t get the chain of. And I can’t change all the wheels the chain goes on. My car have run 500.000 km.
