| Subject: | Re: Oil Cooler Mount Cracking... |
I posted this in response on the RV list, it is one way to avoid the
cracking, figured it was worth posting here:
Matt,
I had the same type of cracking on my oil cooler after about 60 hrs. I got
rid of my standard oil cooler and used a setrab 10 row with swivel angle
fittings.
http://www.hrpworld.com/index.cfm?form_prod_id=276,587_823&action=product
http://www.hrpworld.com/index.cfm?form_prod_id=276,587_3397&action=product
It comes with straight in AN fittings but I swapped them out with one 90 and
one 45 because that seemed to be the direction that the lines wanted to
enter the cooler. I was able to used the standard lines and just make some
mods to accept the setrab cooler. I also beefed up the bracing around the
cooler with 0.125 angle rather than whatever is standard.
The cooler is about 1/3 the size of standard and so there is much less
weight hanging on the baffles. The firewall solution works fine but I
really didn't want to have the hoses "working" with the vibrations/shaking
of the engine.
550 hrs now and no cracking and my oil temps never get above 200F.
The best part is that I was able to sell the standard oil cooler on ebay for
enough to cover the cost of the new cooler and fittings.

You really do want your oil temp to get above 212 degrees to boil out the w
ater & condensation that builds up.

The oil temp probe is usually downstream of the cooler and measures the temp
of the oil right before it enters the galleries..thats why we are putting an
additional sensor in one of the sump drains.even then it will be cooler than
the oil leaving the rockers..so.the oil temp gauge doesn't really tell you
the temp of the oil circulating in the engine..i bet the engineers that
designed the coolers have some charts that would enable you to estimate the
inlet oil temp for a given output temp.just some ramblings

That's what I've also believed, but just read in the Lyc 0-360 book that
the desired "oil inlet temp" - is between 180F and 160F depending on
Ambient Air Temp . . . They never mention the 'desirably' to go above
212F?

| Subject: | RV-8 POH/Flight Manual/Checklist |
Okay RV8rs,
I've worked on my Flight Manual and Checklist most of the day today and
I'm still not half way finished. But, I am posting what I have on my web
site for all to see.
My flight manual cover sheet and section one as well as my checklist are
posted in Word format and you can save them to your computer or just view
them using Word. If you need them in another format (other than PDF), let me
know.
I have lots more work to do on the flight manual to include 6 more
sections with photos, charts and diagrams. It will take some time to finish -
but
finish it, I will.
With their permission, I will also post the POHs that others have written
(none are posted yet). I have seen some excellent POHs that will give you
a starting point or ideas on how to proceed. If you use their POHs please
give them credit for their work.
As always, use the documents at your own risk.
To find the documents, go to:
_www.rv-8a.net_ (http://www.rv-8a.net) and scroll to the bottom left
corner where you'll find a link for flight manuals.
On the flight manual page you'll find links to the documents.
I'm open to ideas, changes or questions.
If anyone would like to give permission to post your POH, please send me a
note and I'll get back to you to arrange transfer.
Regards,
Stan Sutterfield
