Oil Cooler Installation Instruction

[mr bill]

I mounted mine on the back of the gear box, using an aluminum adapter for the different hole centers and rubber shock mounts. The manufacturer recommends isolating the thermostat from vibration.

I used the oil cooler mounts supplied by Kitfox.

Hi Muth,

thanks for posting the oil cooler from Rotax Europe - I guess they are available at all Rotax dealerships. It looks like a really good way of simplifying the hoses - if I see correctly, the thermostat screws directly into the inlet and outlet ports on the cooler? I have the factory supplied on and it ends up with a lot of hoses and an issue of working to get minimum radius turns. thanks again for the post.

I mounted the oil T-stat on the firewall with homemade brackets.

Hi Ross
yes in- and outlet ports matches with the Rotax oil cooler and the assembly is mounted with 2 screws per side and self constructed brackets and shockmounts to the gear box

Thanks Thomas - it looks like a very nice design.

I await more of your flying pics too - they are spectacular!

cheers

Floog, I was looking at your install, it looks solid. However, it appears you used Teflon tape on your connections. Teflon tape should not be used in aircraft. PFTE thread sealant is the recommended product.
With Teflon tape, even when being very careful, small bits can become loose and block passages.

Ralph,

Thanks for the heads up on the thread sealant option. But I'm gonna have to respectfully disagree with your concerns about Teflon contamination. If it's properly applied it's a GREAT SEALANT. Especially in a hydraulic system.

Here's the problem I see with Teflon tape; even if you are very careful putting it on the first time (keeping it off the first 2-3 threads), when you eventually remove the fitting for service, small threads will be left in the female thread roots that you may or may not even see. Then when you reinsert the fitting (with its carefully applied new Teflon tape) it can push those leftover threads into the system where they can wreak havoc. Too risky, maybe years down the line.

I am not an expert, but,
I do feel the need to say that all the maintenance manuals ,documents , including very serious accident reports that I have read suggest teflon tape is not an acceptable sealant for aircraft applications and has caused many a problem.
