I have bought the tensioner and belt required for the ex-mrs pd130, and was wondering how difficult a job this might be, and the potential for royally f**king it up! I am tempted to have a go at this myself, despite the tight spaces that i would need to work in.
I am assuming that its simply a case of taking off the old tensioner, replacing the belt, whacking on the new tensioner [are there specific torque settings for the tensioner? If so, does anyone know them please] and pulling the pin out [as in the pic].

Is it that simple? Do i need to know anything else?
