I busted my oil cooler today, its 100% toast i just spit out atleat 1/2 quart of oil today.

the NCR one is too expensive for my taste, are there other options other then a stock one off ebay or welding it?

I suppose you could purchase any number of aftermarket options and weld your own tabs to make it fit? I mean...if we're already talking about welding anyways ;)

Im not sure if its even practical to buy another one. I was just going to rent a tank of argon tommorrow and run a pass through the inlet/outlet area and call it a day. i think thats where its leaking.

How?   [popcorn]

There's the S4R option. (minor mods required)

There are M14x1.5 to AN-6 fittings which would adapt your engine outputs to AN-6.  At that point, any number of aftermarket options become open to you.

dont make too much popcorn cause i dont know. I hang my oil cooler with a wire 90% of the time when i remove it. theres maybe 10% of the time where i let it sit on my fender. Maybe thats what caused it? but i dont know for sure where its leaking yet. im cleaning it up leting it dry and throwing some baby powder at it.

duckstew thats good to know, i will see what well priced options are out there. pennyrobber, that looks way to small. I already run stupid hot in the city, i dont need a smaller oil cooler. maybe a bigger one!

Check out Earl's products at Amazon.  Here is an example:

My oil cooler has a nasty leak on the right side where the hose meets the oil cooler. i dunno if it is the hose or the cooler but i am definitely interested in an aftermarket solution. NCR has dope stuff but its expensive. I also found an oversized cooler here:

Looks like they are out of stock though. That one is still expensive.

Let us know what you come up with so i can copy it!   ;D

There are 2 O-rings on the inlet fittings into the cooler as well as one crush washer between the inlet fitting and the cooler housing.  Any of those three could be your issue.

Thats what my mech thought too but after replacing the o-rings, it still leaks. Maybe the crush washer? My bike has been knocked over by drunks trying to parallel park in my neighborhood. make the beast with two backsing night clubs! Im thinking it may have cracked something.

isnt ryanracer set up to sell oversized oil coolers?

So, looks like the aftermarket ones are about 10 row, single pass.  I'm assuming they are flat tube and folded fin construction for the core?  Anyone know the tube diameter on the radiator flow tubes in the core?  Also, what's the internal pressure these radiators are subjected to?

EDIT:  The reason I ask is that I have a supplier for high quality full copper cored radiators that I used at my last job, they are super nice, well built and come powder coated - BUT - they are only rated to about 30 psi.

Believe it or not, but this piece has the same frontal area as the stock unit. I hear you about a bigger cooler though. Good luck.

What about Jegg's or Summit Racing?  Gotham Cycles? 

really? it looks so much smaller. was it a straight bolt on for you?

The hoses were a direct fit but I did need to buy a cap as the cooler on the S4R has a small return line that feeds oil to the heads. Also, I had to make brackets to hang the cooler from the frame. Then I had to source a multistrada valve cover to get rid of the old bracket. It sounds like a lot but it really wasn't too big a deal.

Just stumbled across this re-post. I read the original one and it inspired me to buy an 848 oil cooler for my 696. I decided to make my own lines which required me to source all the fittings and so on (i went through JEGS for the lines and AN fittings and Summit Racing for the 14mm to AN 4 adapter ). I originally went with AN 8 lines which ended up being WAY to large so i switched them out for AN 4 which fit better. I just took the bike out today and everything seems to be in working order. I may end up eventually switching the lines to AN 6 as i think the AN 4 lines are a little small and probably somewhat restricts the amount of oil the system can circulate but i'm happy for now and will do some more testing first to confirm my initial suspicions. I also had to fabricate a bracket for mounting the oil cooler that is similar to what is described earlier in the thread, just a few bolts, rubber washers and some spacers from the hardware store. In all i spent around $340 which is better than any manufactured system would run you new. I ended up trying a different type of line as the original 848 lines definitely will not work with how the 696 is set up. It's a synthetic weave instead of the stainless steel lines typically used. The added benefit is weight savings and it's a little bit easier to work with (more flexible). Concerning heat, The return line sits about a quarter inch from the down tube and so far is unaffected by the heat. I have my fingers crossed that it will work out. Right now it is ran around the front cylinder head  If anyone is thinking about trying this i would encourage it. I'm not the most mechanically inclined person but if you have the hand tools required it will only cost you the price of the parts, a weekend and a six pack or two of beer [drink].

Love it!  Just move the voltage regulator so you get some air-flow through that unit...

did you get the cooler from the dealer?  $340 seems very reasonable for such a good looking final set up.

I bought the oil cooler on ebay for about $140 shipped including the original mounting bracket and lines. The cooler was stated by the seller to have had about 1,400 miles on it which to me means practically new ;). The AN fittings and lines were right at $140 with the remaining $60 spent on the oil bypass spring, washers, harware and beer  [beer] It was a fun project that without the waiting for parts only took me a weekend. I did have to remount the horn and the voltage regulator which i may move again sense Duck-Stew thinks i can get some more air flow.... Just need to find a better location.

that is definitely a very original idea and the triangular oil cooler looks a lot better in that location than i would have originally thought.

the oil bypass clip did you get that at a ducati dealer or is there an aftermarket one you can get that fits?

Thanks sbrguy, I thought the triangular shape was interesting as well which is what really caught my eye when i was mulling over how i should do the project. I got the oil bypass spring from ducatiomaha.com. They have a pretty easy OEM parts ordering program or you could always opt to go to the dealer if there is one in your area as it could save you time. I ended up waiting for about a week and a half for the part to get shipped through them to me as they didn't have it in stock. I haven't seen an aftermarket one anywhere except what is offered in other oil cooler kits like comp werks but i'm not sure if theirs is aftermarket or just sourced through a ducati dealer.
