'65 Fan Question

[Clark K.]

Since I could not find an answer to my fan question in the archives, I thought I might get some input from you guys.

During a recent chapter judging, the judges pointed out that my engine driven fan is incorrect. The fan that is now installed (came with the car) has the correct seven blades for an A/C car, but the ends of the blades are "cut off" at an angle. The judges told me that the correct fan blade shape is rounded at the ends.

So, for the everlasting quest for improvement in originality, where can I find a like-new original or an "acceptable" repro fan? -Clark

Here's a link to a post about 11 days ago. I show 2 large pics of my 7-blade fan (although it has round-head rivets, and therefore may have a 1964 MY provenance). Blade tip shapes and angles are unique. GM drawing also shows in Noland's Vol 2, pg. 218.

Re: '65 Fan Question

Clark - The tread Wayne sent you should provide the answers but did I miss something? Is you car an A/C or non-AC car? Pete

Re: '65 Fan Question

My car is a 1965 L76 coupe with A/C. The car has a seven-bladed fan but has been judged to be incorrect. -Clark

Re: '65 Fan Question

Clark,

I have an unrestored '65 L79 w/ AC car and it has a 7 blade fan with the tips squared at the ends of the blades. I believe this fan to be correct for the car and see no reason why an L76 car with AC would be any different.

Re: '65 Fan Question

Clark - Here's your opportunity to educate the judges on '65 C60 Corvettes. The 65 TIM&JG lists the fan for C60 Corvettes to be the 7-blade, 18" dia. fan blade assembly, p/n 3853934 and Wayne has pointed you to the DB thread with the info and pictures and noted Noland Adam's book for additional info (page 218). So if the fan blade assembly on your C60 '65 looks like that you're "good to go" and I'd bring some pictures to the next Judging event of there are any questions.

Have fun.

Re: '65 Fan Question

Clark,

I agree with Pete but only 99.9% as the part number is 3853943 (not 3853934), merely a simple typing error.
My 3 issues of the 1965 Chevrolet Parts Catalog (Oct. 64, Jan. 65 and May 65) all show the fan part number for the "64-65 CORVETTE w/C.A.C. (2nd design)" as 3853943. The "2nd design" refers to the 64 Corvette. If you need a copy of the page in my parts catalog let me know. This is the only fan part number listed for any 65 Corvette w/AC regardless of engine size. I have had a few of these fans in the last 30 years and they were just like the one shown in the picture from Wayne. I have collected, studied, bought, and sold at least 100 or more Chevrolet, Corvette, Camaro, Chevelle, and Nova "muscle car era" fans over the last 30 years and the 3853943 fan is unique, at least in my opinion. My brother, a Ford man, used to call me "fan man".

Re: '65 Fan Question

I am beginning to think that the team of NCRS Flight judges may have been wrong to deduct for my fan. It is possible that they are unaware of the specific fan for a C60 (A/C) car.

However, just in case I need a new fan, where can I find one?

Re: '65 Fan Question

Clark - C60 Corvettes have some different & unique components, so unless a judge has had an A/C car or they been judging for some time, there's a good chance that many judges are not familiar with the Corvette C60 system components.

I suggest you might want to post a picture or two of the fan before you start looking and certainly look at some other 65 A/C Corvettes before you buy another fan blade assembly.

FYI, Long Island does list a 7-blade fan for 64-65 Corvette w/ A/C but I don't know what it looks like.

If your fan blade assembly is configured like the one that Wayne Midkiff posted photos of in the above-linked previous thread, then you DON'T need a new fan (for originality purposes, anyway). The problem, then, would be with the involved judges and NOT the fan blade assembly.

Re: '65 Fan Question

All: thought I'd post this 3rd pic of my '64-5 C60 fan -- this is the view we mostly see, and it shows the features of the angles and bends towards the tip, even better than the GM dwg. in Noland's book, which is only 2-dimensional.

Re: '65 Fan Question

The photo Wayne sent of his car's fan is very helpful. I have the exact same fan, I believe. However, to confirm, where is the part number on the fan located?

Also, how do you insert a photo into this reply?

I don't think that these fans had a part number stamped on them. Some GM fans did and some didn't; unfortunately, most didn't and I believe this was one that didn't.

Re: '65 Fan Question

Here is a photo of my car's fan. It looks like Waynes, doesn't it?

I hope that I did the photo stuff correctly, or I will be embarrassed at no photo!

Hey Clark -- that's the fan, only much cleaner than mine . AFAIR (without unbolting mine, again ) only the letter "H" is present; no "FRONT" or last 2 digits of part # (like "66" for the BB fans 1966+), and no "W" stamped on the back of any of the 7 spiders.

Looks like yours has flat head "button" rivets. Mine has the round head "mushrooms" but mine is not the original unit for my '65 # 014xx; bought fan & clutch assy. at Bloomington decades ago, so probably from a '64 air car.
