Timing belt exchange at wagon R+ Bj 4/2001

Hi all together, yesterday I was braked again in my power when I wanted to replace the timing belt on my own. Unfortunately it had to find out that immediately the engine suspension on the right side of the drive direction had to be dismantled, so it seemed to me and there I had serious doubts whether the engine would not sluggish down and then I could not carry it up. So: Repair set, screws fixed again and built instead on the brakes t. But of course the timing belt is still available at approx. 102500km. Does anyone know more precisely how to carry out this repair professionally? Apart from the very small dimensions in the engine compartment, this would have to be feasible for me, but without any support I have my concerns. Thank you in advance!
