TR3A-Fan removal possibe?

[Adrian Jones <AdrianJones@compuserve.com>]

Hi Folks,
There's a big chunk of  missing metal from one of the fan blades that I
hadn't noticed before(!) - looks like it snapped off where it is riveted.  

I had installed an electric fan a while back, so I'm thinking of removing
the engine fan altogether.  Is it possible to do so without removing the
radiator?  Looks like there is only 3/4" between each securing bolt and the
radiator.

I can turn each of the bolts with a wrench but once I start it will be
irreversible as I can't mark the position of the balance pieces, etc  so I
thought I'd check with you guys first.

Many thanks as always,  Adrian.
