Topic: Oil Coolers — Show me how you mounted yours?

[SKTP]

I am in the process of 836ing my bike. I will be adding an oil cooler. I have the oil filter plate coming and I have the cooler/rad part...

How did you mount yours? Pictures?

This off the horn idea seems smart?

That one looks like a knockoff of the old Lockhart oil cooler that bolted to the horn mount. If the holes in the bracket are better than Lockhart's version, maybe it would sit horizontal? The old Lockhart would usually end up tilted a little bit. Under a fairing no one noticed, but on bare bikes it was kind of an eyesore. It worked well, though, and added a little more oil to the system, never a bad thing!

 Here's my Lockheart you can see the multiple holes in the aluminum bracket, it had an ignition box mounted above it. Obviously there's no horn. I need to address that.

Yep, that's what the one I removed from a rebuild! It had no horn, either.
Another bike I saw (750) installed an air horn instead. It had a little 12 volt compressor that ran when the bike's horn button was pressed. There was a slight delay (fraction of a second) between pressing that button and my ears hurting, but it worked! It sounded like a semi.

Thanks Don.

I have no idea what brand my cooler is but it looks like it was mounted in a similar fashion. I want to figure out ow to have my horn and the cooler...



It tucks in pretty nicely...I am tempted to turn it 90 degrees on one of the frame down tubes, because my exhaust leaves the left side pretty open...The motor is currently out of the bike. Will need to mock up once it is back in

 I had one that was hung from two Adel clamps, it worked well, was on an 1124cc dragbike that did a few bar hopping nights as well.

I think this oil cooler is a 80s Honda. It’s mounted to the frame and horn to cooler.

I'm reminded of the roadracer's oil cooler we made: we went to (car) junkyards and removed the power-steering coolers (mostly old Fords, they were perfectly shaped to fit this arrangement) and mounted them into the outer oil hose between the oil tank and the engine. With the roadrace fairings enclosing the engines, the high rate of air discharge flow that wrapped around the sides of the engine, routed back under the carbs by the fairing, dumped high-velocity air right into the coolers. They were effective with the fairings, but not so much without them, as 'bare' racers discovered. I've long thought that when I replace my oil hoses I am going to do this with mine, as I run the Vetter lowers from time to time and that will both improve engine performance from the more-even cooling across the cylinders (which I've noticed when touring in places like Arizona before) and drop the oil temp as it exits thru there. My hoses are getting old, maybe this is the year!

Here's mine mounted on my K3 with horn, no issue. 
If you mounted it turned 90 degrees, I dont think you could run the lines cleanly.

If we had a massive charging system I thought about using a turbo scavenge pump to pump oil in it's own circuit from the tank, through the cooler, and return back to the tank. I had never really looked at the specs on a scavenge. This one here is IMHO WAY bigger than needed.

2GPM Scavenge Pump Rate depending on oil temperature/viscosity, 30+ PSI continuous as Pressure Pump
4 lbs Total Weight, 2” Diameter Motor
Operating Current: 12 VDC version is <5A nominal, 15A maximum

Perhaps there is some sort of OEM type scavenge pump avail out in the world that is smaller/lighter and more suited to handling this task.
