Slits sent me a fan for Waide's engine and it doesn't fit inside the housing.

As far as I'm aware, there are only two sizes: 245mm and 226mm ('78-'79 only)

I have a 245mm housing. This fan appears to measure 250mm, but I'm unaware of anything over 245mm ever being produced.

All of the 245mm (early, late and 5-blade) are interchangable. Ron sent an early style 11-blade. It should fit.

Liz's early 11-blade does fit.

Anyone?

really early sandcast alum ring fan you have there .

cut it down in a lathe .

unless Slits has the alum. ring then he should sell as a pair.

I was hoping it was a part off of 114.

Slits could eBay it for $$$$.

I did notice the casting looked rough, but why can't I find ANY reference to this size fan?

I have the ring .... he didn't request it.

I didn't sell it .... I just sent what he asked for.

Now, if the fan was in an engine fire would it swell 5 mm?

I am headed to the parts stash to get the number off the ring, but as I remember it was 3R.

Hot enough to swell=Hot enough to melt IMO. So I don't think so.

The fans should be magnesium. How can I tell this is aluminum without filing it? I can tell the difference between mag and aluminum when I file it, but otherwise????

255 dia.
245 on top of 255
difference in rings

Fans are mag ,The ring is alum on the .03

Thank you very much.

Ron, eBay calls.$$$$$$

If you hold a torch to it and it melts, it's aluminum. If it turns into a flare, it's magnesium.

I believe there was also a 250mm. Rare though. Great thread here:
