[Healeys] Fan

[Roger Grace]

Steve thank you; yes agree they are different and the one in my car does not have those semicircles; the photo used in the Moss notice photo may have just been a generic picture and I tend to concur with you that the later ones without the cut outs may not have had the problem but were recalled to avoid any confusion;  I plan to review with Moss next week (if anyone has any history) and make a decision then; I am probably going to change to the 4 blade one as have not had any cooling problems and also have an oil cooler fitted.

The picture of the fan in the Moss notice is not the same as the 6-blade Chinese fan I was referring to earlier that failed in my car.   It looks very similar, but it does not have the semicircular cutouts in the fan hub below the blade like the older one.  I’ve tried to illustrate this in the photo, within the limitations of Paint.  The cutouts may have been reliefs for bending the hub arms during manufacture, but apparently they caused a concentration of stress leading to cracks at that location when the blades flexed/vibrated.

 

 



 

 

It would appear that Moss found new problems with the later design that they selected to avoid the problems of the earlier one.  In any case, I agree with Mike that it would be a good idea to remove these and try something else if you have one installed in your car.   A new fan is a lot cheaper than fixing damage caused by a flying blade or two.

Correction...my mistake...

I had not realized that Moss had used the AEC76 as their pattern for the since recalled fan....I would suspect that Roger's is one of the recalled fans see here.

Might be smart to get that off .

BTW after trolling through my old database I managed to glean what I believe is the original part number for the original Texas Cooler. 
I believe that they were a Hayden product part #A8758. I'm pretty sure that they are long since discontinued.
