Subject: | Re: Oil Cooler's... |
I've been running a Setrab 10 row for around 750 hrs, no problems, temps
often run too low and so its half covered with AL tape. It's about 1/3 the
size of the standard Vans cooler.
They are made of aluminum rather than brass and AL just works better for a
heat exchanger.
You can get aircraft fittings on them too, they even have swivel fittings
at 90 and 45 degrees available.

Matt,
A few thoughts:
- Mounting the cooler on the firewall solves the "heavy vibrating object
mounted with a large moment arm" problem. Attached photo is how I did it on
the RV-10 (not shown is the forward cooler support attached to the engine
mount). On the RV-8A I mounted the cooler on the right side of the firewall
with the 3" hose connecting on the right side of the plenum. I believe most
8s are on the right side as there is more room.
- Mounting the cooler on the firewall allows for an easy "oil cooler air
butterfly valve" install in the 3" hose between the cooler and firewall.
Here is one place to get this butter fly valve:
http://www.nonstopaviation.com/controller-cooler-p-14592.html?osCsid=bc77b7d
1ef861c7cd83d92c5a28010dc
- Consider using the AirFlow oil cooler if you end up buying a replacement.
I have this on my RV-10 and have never had a oil temp issue. Here is one
place to get this cooler:

I thought the source of the cracking had been addressed. I had some issues
with the left-rear baffle flange cracking too in the beginning. I made the
rear baffle nice and strong, but used the stock left-rear piece which was
.032. It just wasn't up for the task. I later added a cross strut from the
crankcase just ahead of the hoist loop all the way back to the left rear
corner and added some .063 angle stiffners over the oil cooler flanges for
additional support. I'm wondering if I cracked the flange today taking the
oil cooler off. It was pretty stuck on and I was having to do a fair amount
of prying to get it to separate from the gasket. I would have been more
careful if I'd of realized those flanges are made out of such crappy pot
metal. Man, they are soft.
Since I'm rebuilding, I decided to rebuild the left-rear baffle part and was
taking the oil cooler off today to accommodate that. That's when I noticed
the crack.
Attached are some pictures of the setup prior to disassembly today.

Matt,
Nice job on those angle reinforcing plates. I would suggest examining the way
the reinforcing plates lay against the oil cooler flanges. If the reinforcing
plate presses on the radius of the oil cooler flange, it will introduce a stress
into the radius. Your cure to your cracking problem may simply be to radius
the reinforcing plate(s) so they don't press on the oil cooler's flange radius.
Regarding the softness of the oil cooler flange, that is a good thing. Soft metals
are more ductile than harder alloys. Harder is generally stronger, but also
more brittle.
Charlie

I just dug back through my emails to find the skinny on the Setrab cooler.
I'm pretty sure it is this one:

<http://www.hrpworld.com/store/default/100-series-std-10-row-oil-cooler-3-tall-m22-ports.html>*
It comes with straight on AN fittings but I couldn't get them to work
in the space I had so I used these:
http://www.hrpworld.com/store/default/an-10-x-m22-hose-fitting-90.html
These fitting are mega expensive but swivel which takes alot of the
stress off the attach points.
I went this route for a few reasons:
I had the stock cooler completely covered with AL tape and still
couldn't get over 200 F temps.(Too much cooling)
My baffles cracked from the weight of the stock cooler.(too much weight)
I knew of a rv-6 built by 3 engineers(one is a DER) and they've flown
400 hrs trouble free with this cooler.
I didn't do the firewall mount because i didn't want the hoses
Even still when its cold I can't get over 160 F.

I've been running a Setrab 10 row for around 750 hrs=2C no problems=2C temp
s often run too low and so its half covered with AL tape. It's about 1/3 th
e size of the standard Vans cooler.
They are made of aluminum rather than brass and AL just works better for a
heat exchanger.
You can get aircraft fittings on them too=2C they even have swivel fittings
at 90 and 45 degrees available.

Greetings RV'ers=2C
On the RV-8=2C I've got Stewart/Warner 10610R 10 row oil cooler for the IO-
390.
It's mounted on the rear baffle and its worked well and kept the oil temps
in
the low 180's under all conditions.
I noticed today=2C that the outside mounting flange that goes next to the b
affle
is cracked. I suppose I could get it welded or brazed or whatever they do
to
aluminium=2C but that seems like a hack.
Apparently=2C Chief doesn't carry the Stewart/Warner brand anymore and has
to different
variants of the Aero Classic brand in the 10 Row 10610R compatible unit.
One is the "Standard" model for $269:

The other is the "HE" (High Efficiency) models are $575:
http://www.chiefaircraft.com/aircraft/oil-system-filters/oil-cooler
s/he-series/aec-8001646.html
Any thought's on either of these two options? Pros and cons. The HE model
s look
a lot like the S&W model I have=2C assuming the pictures are accurate.
Thanks for the feedback.
Matt

I originally flew my O-320 RV-6 in Southern California heat during Septembe
r 1997 with an oil cooler mounted on the firewall with 3" SCAT tubing runni
ng to it.
I constantly had high oil temperature. Relocating the oil cooler to the en
gine mount behind cylinder #4 with a full size opening duct to it just an i
nch behind the cylinder lowered oil temp 30 degrees F.
In a high heat environment with high power settings=2C I would not use a fi
rewall mounted oil cooler and 3" SCAT to it. There is not enough air flow
going through the oil cooler with the setup that I originally had.
