Does the RV-10 and/or RV-14 firewall mounted oil cooler fit on the RV-7 firewall

1. Does the RV10 and/or RV14 firewall mounted oil cooler fit on the RV7 firewall?

2. If the larger physical size of the 10 & 14 oil cooler prohibit it from being used on the RV7, does anyone know of a ready-to-go kit that allows a firewall mounted cooler on the RV7 with minimum fabrication?

3. Please post photos of firewall mounted oil coolers on RV7's?

Thanks guys!

Are you concerned about cooling? Thinking of going bigger. I did and kind of wish I didn't. I live in central Texas and went with a larger oil cooler and find it difficult to get the oil hot during the cooler months. I have it tapped up totally and still can only get it above 180 with an extended climb above 6000 feet. My friends that went stock have no issues in the summer and still tape up theirs as well. Lets see where others weigh in on this.

Guess I should have clarified. Thanks for pointing that out.....

I am not interested in a larger oil cooler. I just don't like the weight and stress up on the cooling baffles and repairing cracks and patches, etc...

I can fix the current cracks on the -7 I just purchased, or relocate the oil cooler to the firewall?

Thought about using the 10 or 14 oil cooler bracket if it fits (or similar bracket if available) on the firewall of my -7, but use the standard smaller oil cooler.

Hope that clarifies things.

Advise appreciated.

I mounted the larger oil cooler from the 10 on the firewall of my 7A.
I also installed a 4" butterfly valve to control the airflow through the cooler.
This setup has worked very well for me for nearly 150 hours now.

Hope this helps,
Jason

I mounted the RV10 oil cooler bracket to the firewall of my RV7A along with a 4" butterfly valve that will be controlled via cable from the cockpit.

The bracket from the RV10 kit has the inlet hole offset to the the inboard side which would cause interference with the scat tube hitting the motor mount tube.

In my case I solved this issue by moving the hole over to the other, outboard side. Moving the hole turned into a bit of a miserable welding job and I suspect the alloy is 2024 alclad, which is considered a non weldable alloy.

I got it done and believe it is strong and serviceable. I do not recommend doing it via welding. The hole should have been moved over via sheet metal work, cutting and riveting etc. If you were to go to that much trouble you might as well just make the thing yourself.

Mine holds the legendary 8432R oil cooler and I look forward to seeing this combination at work in this summer's AZ temperatures. With everything in position the bottom of the cooler is very close to a motor mount tube but I did not have to bend anything to gain clearance.

What's the best source for these large diameter butterfly valves?

The 10 cooler fitted on a 7 with some modifications

Thanks, Bob. Avery is, for some reason, not a place I would intuitively look for this part... DOH! :-)

There was another company manufacturing and selling them. One of the owners passed away and the remaining owner operated the business for awhile. Then he turned over sales to Avery.
