Turbo oil drain leak

[MarkM]

I need to replace the oil drain gasket at the bottom of the turbo (1985 300TD), as well as the grommet and o-rings on the turbo oil drain tube. The gasket where the drain tube attaches to the bottom of the turbo is very hard to get to. Here is my question: at the bottom of the turbo, there is a cylindrical unit attached to the turbo housing (I think the waste gate hose attaches to it)...can I just remove this thing in order to easily get at the gasket, and just re-install when done? This seems to be very straightforward, but I don't know if I will upset any adjustments, or if there are springs or such that will be very difficult to get back together.

Thanks,

Mark
