Oil cooler installation photo

[sdemeyer]

I'm in the process of installing a new Oil cooler on my IV with round cowl and 912 UL. I'm thinking of making a bracket out of heater hose with one end bolted to the gear housing and the other bolted to the cooler.

Before I do this, I thought I would get an idea of how others installed their cooler. Do any of you have photos of your installation?

Thanks,
Scott

I have mine going off the front just under the prop. John has all the setup for doing this.

locating the cooler under the prop shaft works pretty well . the mount brackets on mine are attached by the forward engine mount bolts

surprising it works really well . kinda amazing how all of a sudden it all comes together . for the cold weather i made a sheetmetal cover for the cooler . between the cover and the thermostat it ran pretty good in the cold weather we had last month .
the engine came with a fitting at the oil pump that was too small for a 1/2in or metric hose , what ever that is , 12 or 13mm. had a difficult time locating the correct one . received a couple from lockwood and airwolf that were incorrect also before finally finding the correct one .

being from yelm, you don't need all that. Just the RU2700 filters from K&N. Also I will add, you should no matter what, search out someone to balance the engine, prop combo. I just did mine and I always had fuel smells and such when taxi to the hangar, now it's nice and smooth and fume free. Much better in the air, no more vibrations.

what do they do when the balance the eng and prop ? what did the eng balance have to do with the fuel smell in the cabin ?
smoother has got to be better

[Slyfox]

The balance is done by putting a device on the engine. Dynavibe http://www.rpxtech.com/rpxweb/Dynavibe.asp is the unit I have, there are others. Now understand this. If the engine is vibrating badly, which mine was, than the fuel in the bowls slosh around, causing fuel to come in more. At least this is what was happening to mine, the plugs are cleaner and the smell is gone, yaaa.

the balancing thing sounds like a pretty slick deal . only a little expensive . sounds like balancing a fan on a ge cf-6 only alot quicker . now i can see how you got the gas smell , must have been really rough running .

I tried real hard to find somebody in my town to do the balancing. What a joke. I went to the big airport with my rv and they tried to balance it, but the equipement was outdated and stopped at .5ips. This machine does down to 0ips if you want to do that. I have two planes and I figured I'll check it on the oil change or every other change, takes only a few minutes to hook up. So for me it's well worth it. Oh and most people charge about 300 a pop.

Thanks for the picture Chuck, exactly what I was looking for. On your hose routing, are you coming from the tank, through the cooler, through the thermostat, over the top of the motor into the oil pump and finally back to the tank?

Mine is setup with a cooler laying flat on top of the motor ,in the return line. I don't think this is correct and my cooler doesn't do squat because no air flows through it, hence the reason I am changing the setup.

Thanks,

thanks for the info . guess ive heard of engine balancing but didnt know how it was done . i guess at 300 a wack and two planes , it wouldnt take too many balances to pay for the gizmo

steve , another picture of the cooler . the hose going to the t at the pump inlet from the aft side is from the thermostat . the routing is from the tank outlet on top of the tank to the thermostat , from the thermostat thru the cooler to the pump inlet or the thermostat bypasses the cooler to the inlet of the pump . hope that helps
