MD2020 fuel injector check part 2/2 - assembly

It is pretty easy to remove the injectors and get them checked, but a bit more difficult to install them again.
Under the injectors you have a insert and under that insert there is a copper ring, and the whole thing is of course stuck pretty well so quite a job to remove without a special tool.
I then bought a internal bearring remover in the correct size, but then there was a new problem.
You also need new copper washers and have to tighten the injectors with a torque wrench.

Tools and parts I used :

3580631 - 3 pcs. gasket between injector and return line - 37 USD
3580077 - 3 pcs. gasket under the injector - 17 USD
3580075 - 3 pcs. gasket under the insert - 24 USD

Beta torque wrench model 606/10 3/8" 20-100 Nm. - 208 USD
Jackhammer (slide hammer) and special tool - 72 USD
