I have the same job ahead... amazing that you've shown me the way. What's satisfying (and I haven't even started yet) is that your work environment is just like mine. Not a clean workbench, but a cramped fairly dirty engine bay. Now to find a new ZF12m.

Thanks for the video, I'm just about to replace my hurth 50 with a zx5 and I didn't have a clue until I found this video. Thanks again.

I'm looking at doing the same thing, is the gear ratio the same between the hbw 100 the the zf12? Did you lift the engine 10mm because of lack of space in the engine bay or is there a 10mm difference between the input and output spindles on the new gearbox? Any help is. Much appreciated
