compressor housing, an easy way?

[monka]

i have removed the big circlip that holds the compressor housing on my ct9, but is there an easy way to get it back on

Its easier to put back in than take off mate, just wedge 1 edge in first, then spin it using the pliers or a screwdriver, needs 2 pairs of hands though ideally.

I can't really describe it in words lol
