No it works like a typical spring loaded belt tensioner. The hydraulic tensioner sets the pressure of the belt tension, the pulley determines the depth of the hydraulic tensioner on the arm
Long story short, I set belt tension too tight on the pulley and I was able to hear and see the timing arm hitting the hydraulic tensioner. That is how the arm becomes grooved like in his picture
Also to note, never leave the car in gear without the parking brake on. This can cause the damage seen in the arm. The engine is being forced by gravity to apply the force of the car against the rotation of the engine. Causing the arm and all of the timing components to take that force. Really hard on the entire engine
I always use my parking brakes. Even on my automatic daily driver. I'm weird about that .
The pin moves freely so the tension should be good.
