Right then:

I've got a brand new TD04H sat here.
Customer wants is put on a motorbike so I am busy fitting it however:

The compressorhousing interferes with the frame, I can easily rotate it BUT can I rotate it anyway I like or only the two pre-determined positions as dictated by the dowelpin in the housing? I can easily mod it but I'm wondering if for some reason it wouldn't work properly if I turn it in a certain position?

Second problem is the bearingpart: can I rotate that as well?

Last one: there are 4 holes in the bearingpart, one on each side: 1 has a flush surface for fitting a flange, with the holes for bolts, the other three have internal threads and nothing else.

So wich ones are for oil and wich ones for water and wich of the oil ones is the drain???

I'm assuming the flange one is the drain but what do I know...

Hope someone can offer some advice!
