[TR] TR4A - plastic fan - advice?

[Cliff]

So, I wanted to pull the fan hub extension because I wanted to fit an 8 
blade plastic fan backwards.  However, the center hole in the fan is 1/8” 
smaller than the diameter of the plate at the end of the fan extension.  I 
was thinking of turning the fan extension down.

But now I think I'd rather not pull that dog bolt if I don't absolutely have 
to.

Options:
1 - leave as is and put the original metal fan back on, at least, it’s a 
semblance of a fan.
2 - mount the plastic fan frontwise and give up the access to the end of the 
dog bolt.  Mounted frontwise the fan is only about 1/4" from the radiator.
3 - go modern and put an electric fan.

I'm guessing many on the list would choose Door Number 3.  But I'd really 
rather have the plastic fan, if practical, because, well, its paid for.

Has anyone fitted one of these plastic fans, and if so, how did you mount 
it?

Thanks in advance,

Cliff

Hi Cliff,
There is a hefty long bolt that connects it to the crank shaft.

I need to remove the fan hub extension (part 128318).  I’ve taken the nuts off of the 6 bolts that pass through the pulley.  It seems still attached solidly.  Rusted in place perhaps?  Or is there something else to be done to get this piece off?

Thanks,

Cliff
