Yeah, what he said. More specifically, the turbine shaft which is sticking up, should push straight down through the housing, it may be a little sticky depending onthe seal condition etc. Don't loose the dynamic seal assembly sitting on top of the housing, it is a little spool and the mating plate with the cut out that fits in it. Observe carefully how it goes together, I think it only goes one way, but better safe than sorry.
