defroster fan on steering column

Recommended Posts

My 36 Roadmaster has an aftermarket fan on steering column that has soft rubber blades. The rubber is shot. I haven't found an acceptable replacement. Any ideas would be appreciated.

Most likely a Trico brand vacuum fan. There are several listed on ebay both the rubber type and the caged type which has a metal fan. Sometimes parts and pieces are listed. Or take yours apart and make new rubber blades and reassemble. Personally, I bought the caged type for my `36 40series coupe.

Thanks. I didn't expect to find blades. I can make em if i can find the rubber. Seems like some rubber gasket material might work but the local auto suppliers don't even know what that is anymore. i am not aware of modern uses for that kind if stuff that might be a source.

One-in-a-billion chance it matches the blades I have in a box of junk... But do you have a picture?

I use liquid polyurethane rubber to make some parts for real orphan cars we get in the shop. It is the same rubber used in motor mounts so it is tough. If your blade is complete or can be temporarily patched you can spray it with mold release (Pam cooking oil) and use it as a pattern to make a plaster of paris mold. For the center hole you can spray mold release on a wooden dowl or wrap a layer of Saran wrap around it or you can put the new blade on dry ice and then turn or mill it. The latter would be tricky on something with very thin edges where a slight bump could break them when frozen. A search on "liquid polyurethane rubber" will give sources and mold techniques.

My '37 had this fan attached to the column.  I haven't taken it apart yet to clean and repaint.  It's on my list of things to-do.

 

If you need to use it to create a pattern  (that is, of course, if this is the correct fan you need), let me know and I can send it to you.

This is what I had in a box of junk. It got mixed into a box that was supposed to be for 1918 Buick parts. Obviously it isn’t. Don’t know a thing about it other than it has rubber blades and has been in that box for at least 50 years.

Great "air conditioner" for the period.

Yep, and speaking of — after seeing the photo of Gary W’s fan I’m now pretty sure this fan was out of, or intended for, the 1940 Buick coupe my car’s prior owner also owned. It got mixed into a box of original unsalvageable ‘18 parts that had been kept for patterns/reference.

 

An attempt to reach out to the buyers of the ‘40 was shot down. The owner’s family were rather upset when they discovered the guy who bought it for his ‘little museum’ was actually a dealer. Thought if both cars ever knowingly crossed paths at the same show at some point the family would appreciate the photographs and learning the ‘40 eventually found a home that actually loved it for what it was. Also thought of giving them this fan once I knew what it was — but it’s been too many months.

 

I have no use for this fan, in fact, if I ever get the ‘18 running as well as Your’s Larry, I’ll be needing more protection FROM the wind!


I can’t see any markings on it, no idea what it is, don’t know if it even works, maybe only good for parts? It does look a lot like the one Gary W pictured in his ‘37. If anyone has any use for it it has the typical ‘pay it forward’ price that goes along in this hobby. Can take more pictures....

Just figure it belongs in use.

With perseverance, time, and money, you can get it running great. 

 

Remember my thoughts on these 100+ - year old cars.  Drive it, break it, fix it, repeat

 

Also remember that the really old car ownership is not for the faint of heart or wallet.

Wow! Thanks for all the helpful ideas, offers to loan stuff for patterns etc.

My fan is almost identical to Ben's. The hub and blades look exactly the same. I will contact Ben directly.
