So I scored new (reproduction) 13 blade red fan to replace the 7 blade yellow fan on my son's 75 engine (go figure). The new fan from TRF has no metal sleeves in the four holes. Also bought the appropriate adapter and 8 bolts and flat washers. Then I check out Moss's website and their fan has metal sleeves already in their fan. Hmmmmm. Anyone have experience with TRF's fan? Plastic fan spinning at 3000 RPM for hours seems a little risky without som kind of reenforcement. The old yellow fan has sleeves.

Actually, this is for the yellow fan. This won't fit the red fan. Waiting for TRF to open to see what they say.

It never ends. TRF called Moss to see if indeed their 13 blade fans had metal bushings. They actually do not. Found that the bushings caused stress fractures in the plastic so they only sell the un-bushed fans, just like TRF. So, I cancelled the Moss order, will keep the TRF fan, and put it on with some Blue Loctite.

ISTR the originals are sleeved. I suspect the Moss ones which cracked(and I remember the thread some time back) had them pressed in after molding, and were not molded in. Pressing them in would have put more stress onto the hardened plastic, whereas molded in would have the plastic adhered, rather than force fit...

My original 13 blade fan had the steel inserts, as did its replacement. Broke one of the blades but never had any stress fractures.

should we suspect the current polymer composition is different from 40 plus years ago?
my original 13 blade red fan is still in position... no frets.
todays are probably recycled con--ms... brittle..no elasticity left...

the fan needs the metal inserts, period... they take the torque load ofthe bolts, not the plastic..., well, polymer...

Just curious with this question.

Any chance you can show a couple of pics of the TRF 13 blade fan and the adapter like Dicks picture?

I am wondering why TRF has gone to an adapter to mount this,
