Seems like someone one this forum should have the material info on these components.
I've been staring at the 'flappers', the only thing that bothers me is why the right one is never fully closed. Does anybody know for sure? (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif)

Yes. I know for sure.


After the engine fire that totalled Betty's 74, The Arlington Texas fire marshall's report stated that the fire started due to a gasoline leak, and was accellerated due to the manufacturers use of magnesium in the engine fan shroud.

Thanks Clay, I guess that solves the engine shroud material question, Magnesium it is! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Now somebody tell me why the right side cooling flapper is always 1/2 open and I'll let

It never closes completely because you always need SOME air moving over the oil cooler.

Ernie, I think you could be correct about the oil cooler needing some air always.
In other words...... if anything goes wrong with the system (and it does) the oil cooler has the continuous partially open flap as a safety. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

One last question here, I have an old bellows with a pin hole in it, has anybody repaired one of these?

It's brass right? ('nother material question)Seems as though a good high temp silver solder would work. (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

I took an old ;eaking bellows to work. Cleaned it in an ultrasonic cleaner and found that it's made of copper.......Going to try an silver solder it next week sometime. (IMG:http://www.914world.com/bbs2/html/emoticons/blowtorch.gif)

Great job on the pics.. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

Let me clear up a few small pieces:

The drivers side flap when closed opens the passenger side flap. This cuts off air to the drivers side cylinders (to warm them up) and lets the air on the passenger side go OVER the oil cooler instead of through it. The passenger side also tries to block some of the air for those cylinders (warming that side up also)

Now. You can remove the drivers side flap and rod that runs across. But you MUST leave the oil cooler flap in place and permanantly flowing air over the cooler. I do this by placing the flap UNDER the two guides in the engine tin piece that is placed over the oil cooler. This ensures me that the flap will NOT move under any circumstances.

Recommendation: leave them in. It is up to you whether or not you use them. Just make sure they will go back to their default position (open).

Surprised somebody hasnt come up with a different method for controlling the flaps.

Here's my idea for a manual control cooling!

COLD POSITION - "UP"

Be careful. If you forget.... bad day. The engine will burn up in a few miles depending on how cold it is that day.

Clean engine setup. Nice ventilator tubing. Do you work in the medical industry? Interesting use.
I wonder if it is metric (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Thanks for the warning!

If I blow the 1.7 then I guess I'll just have to build that 'Massive 4' sooner than I thought.

The clear tubing isn't metric but the I.D.'s run tight. It's reinforced high vacuum tubing $$.

I work in Materials Research lot's of Exotic High Vacuum Equipment around. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Yes, I know for sure. I watched Betty's 914 while it burned. The fan shroud lit off and it looked just like the magnesium flare we made in high school chemistry class. It took 2 huge CO2 fire extinguishers and 1/2 of a big pumper fire truck's onboard water supply to put the damn thing out.


It is DEFINITELY Magnesium.
