Could some of you folks that have an stock shroud with the stock fan and fan clutch setup make some measurements for me and photos if you would?

I have a 69 with a 350 in it, a factory a/c car, 21 inch radiator. I have a long water pump. With my current setup, the fan is completely out of the shroud, and we know what that means at idle. I bought a replacement shroud from Rick's Camaros a while back as the car didn't have a shroud when I bought it. I have a 7 blade fan and fan clutch.

John Z told me that the fan clutch I have is incorrect and that the shaft is way too short. And we know he knows his stuff. What I was wondering is if some of you that have an original setup, could measure from where the fan bolts to the fan clutch to the end of the fan clutch that bolts to the waterpump.

Also, could you measure the top of your fan shroud from front to back, (radiator to water pump). Mine is 6 inches.

With these measurements, I can order the parts from Rick's and get them to measure them before shipping them. I don't want to have to return them.

Thanks much,

Rick

Here's the comparison - your photo on the left with the aftermarket clutch and super-short shaft, and the stock '69 setup on the right with the Eaton clutch and 772 fan blade. :thumbsup:

I can see the difference. Do you know what the measurement is between the end of the fan clutch (the part that fits up against the pulley) and where the fan bolts in? On the one that I have, it is 1.5 inches. I need an additional 1.5 inches to get the fan 1/2 way inside the shroud.

And since I have a repro shroud (Rick's reproduction version and not the original GM one), I was wondering if some of the distance was because the repro is not as wide as the original.

I'll be ordering the correct fan clutch from Rick's tomorrow, but want to also see if I need to get another shroud. I'd hate to get the correct fan clutch and still come up short.

Do you know what fan this came off of? The numbers on it ar 914087A75. Maybe the blades on this one aren't as wide as the 772. It could be that I need to get both fan and fan clutch.

I just happened to have both shrouds for a '69

I will give you two different top measurements because there are two different points to measure on both.

small block shroud--in the middle where the bracket mounts and the plastic jogs in measures 5.5 inches
small block shroud--outside of the mounting bracket area measures 6.5 inches

BIG BLOCK--in the middle where the bracket mounts and the plastic jogs out measures 5.5 inches
BIG BLOCK-- outside of the mounting bracket area measures 3.5 inches

Hopefully that makes sense to everyone else

Mike,

Thanks for the reply. I re-measured mine this morning (I have a small block) and found that the part with the indent for the bracket is 5.0 inches and the overall width is 6.0 inches. It's starting to look like the shroud is the problem with the fan not being inside of it. I'm going to go to Rick's tomorrow and get them to pull an original and a repro to measure. Fortunately they are about 40 miles from me.

Thanks again,

Rick

Rick dont forget JohnZ's pic there shows the big difference in shaft length, which if you got the right one, would put your fan into the shroud without replacing the shroud I think. From your last post here, it almost seems you think a new shroud will fix it, I dont think it will.
But glad John posted that, I didnt know there were 2 different lengh clutch shafts for the 350.
:)

Rick - what are you trying to accomplish? Just get the fan into the shroud, or are you looking to make your car correct per factory spec's? From the pic's I've seen your engine compartment isn't stock so my suggestion is just get a spacer like I provided a pic of in your other post. Simple inexpensive fix and you are on your way. I provided you with comparison measurments yesterday showing your shroud was 1/2" short but as I said then the shroud itself isn't going to fix the problem...

Here's your other post so everyone isn't missing the whole picture, much better not to start new threads on the same subject...

Jim,

I bought the correct fan clutch and 772 fan from Rick's and put them on the car on Wednesday evening. This brought the fan closer to the shroud, but still not inside. All the parts are correct, including the water pump, the fan clutch, fan, shroud, and radiator.

What I'm suspecting is that possibly the core support is not properly positioned. Who knows what happened to the car before I bought it. I know that it was drag raced. It could have been wrecked. Some guy in New Jersey had it, I think his name was CJ. You may remember back a couple of summers regarding a lime green 69 Camaro that Jason Sabowich bought off of ebay. This is the one that had bondo on the engine to cover a crack. Jason (in the military) had to sell the car as he was transferred to Germany, but ended up in Hawaii.

Anyway, I've re-done a lot of things, fixed some things, put new things on it, etc., and have a very good driver car. Just a couple more things and I'll be done, with the cooling system being one of them.

What I've decided to do is to by a 67/68 fan shroud for a non-a/c car. This fits the 21 inch radiator that I have in the car and puts the fan shroud depth at 7.75 instead of the 6.0 that I have now. That should get me 1/2 way inside the shroud. Since my car is not a numbers matching car, nor a show car, right now I just want to get it out on the road and enjoy it, and this seems to be the easiest fix. I could go with a fan spacer, but that will put more wear and tear on the water pump. This way, I've got it covered.

Rick

ps: The car is still lime green. With the amount of $green it would cost me to have the body work and paint changed over, the lime color is growing on me.......
