AC hydraulic tensioner issue?

[Smudgemanuk]

Hi all,

I am currently replacing my AC hydraulic tensioner and pulley. M52TUB28

However, there is a metal bush on the old one that isn’t on the new SKF one. I have a press that I could press it out with and then press it into the new one.
Is this normal to have to do this?
And am I correct in assuming the plastic bits on the new one stay in place?

Thanks

Well I ended up pressing the bush out and then gave it a wire brush and a clean and pressed it into the new one.
All seems good now
