AW70 extension housing help

Jim

Hey all,
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...

Cheers,

Jim.

Seal was definitely in backwards. I wouldn't panic too much about the mark in the housing unless of course you have another readily available and/or it leaks from outside the seal.

I am not too sure about the sealant, I see no reason why it would not be ok to put some there. I am not sure how they are designed to seal to prevent oil leaks, perhaps it is purely by a snug metal/metal fit.

Thanks Rob,
I'll just tig the housing and sand it smooth, if it leaks again I'll fix it properly.

Hmm the AW70 extension housing is much less similar than I expected to the AW71 extension housing.
