I'm replacing the seals/bushing on my AW70 extension housing as it was leaking a lot of oil. A couple of questions:
1: Is this normal? I haven't seen gasket goop smeared all over a flange like this before. Greenbook doesn't mention sealing the flange nut....
2: Previous owner - dodgy McBreakstuff - has apparently used a screw driver to remove the old seal and scored the inner housing surface.... does this mean I need to find a new extension housing?
3: Which way does the seal go? The previous one was like image 2 and I could see between the shaft and the seal...
