Greetings RV'ers,
On the RV-8, 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, that the outside mounting flange that goes next to the baffle
is cracked. I suppose I could get it welded or brazed or whatever they do to
aluminium, but that seems like a hack.
Apparently, 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:
http://www.chiefaircraft.com/aircraft/oil-system-filters/oil-coolers/standard/aec-8000081.html
The other is the "HE" (High Efficiency) models are $575:
http://www.chiefaircraft.com/aircraft/oil-system-filters/oil-coolers/he-series/aec-8001646.html
Any thought's on either of these two options? Pros and cons. The HE models look
a lot like the S&W model I have, assuming the pictures are accurate.
Thanks for the feedback.
Matt

for what it is worth, I see nothing wrong with welding it. but you need to correct
the real problem that caused it to crack in the first place. It maybe flexing
or vibration mounting etc. but something caused it.

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.

They can give you pricing to repair, and probably have a source for exact
replacement as well.

Matt-
I see the probability of much motion in that area what with the sheet metal
carrying the load and a long vectored brace like you have swinging it. I
can show you a better way to mount it if you contact me directly or you can
take some other advice that I'm sure you will get from the listers.
