The ol' Paul Smart developed a leak in the oil cooler- No Bueno!

Here's the main thread-

as your answer in that thread, a radiator shop should be able to braise a seam. Radiators, oil coolers and trans coolers all work pretty much the same.

Cheaper than getting a new one, but will have to repaint t after though.
I'll update this later at a convenient time Thank you for tuning in.....

Are they braised in the 1st place? Also, I understand that the pressure is much higher in the oil coolers than in a standard radiator. Anyone have an idea how much pressure it needs to withstand?

#3
between 21 psi hot at idle to 57 psi hot at rpm load 4500+

between 35 psi cold idle to 72 psi cold rpm load 4500+

shouldn't very much at all from these on the PS

And these numbers would be similar to auto numbers and oil coolers also


EDIT: I forgot to add that these are for the 900 motor

Isn't your bike under warranty?  Unless it is backordered your dealer should be able to get one in a few days.  you could bypass the cooler temporarily.  If you choose to go to a radiator shop do make sure they understand the pressure it will be subjected to.

Of course not! The warranty expired 6 weeks ago  :P
I'm going to give the radiator shop a try. Should be a lot less than $300., & I'm going to ask for an 80PSI pressure test.
Thanks for the input, I'll keep y'all posted  [thumbsup]

Six weeks :(  I would try speaking to the dealer, can't hurt.  If my memory works KTM uses the same cooler and sell it for less.  Anybody out there know if I am correct?

Whew! I took the oil cooler to a radiator shop yesterday (yes, they were open Memorial Day), & they pressure tested it, but couldn't find a leak. They went ahead & put a nice fat weld around where I thought it was leaking. Did it while I waited... $10.
Got it back together & fired it up, & let it idle for quite awhile. Looking good, so I rode to the gas station.
Got it up to around 8k rpm, & about 210 degrees.

NO LEAK  [thumbsup]

Thanks for everyone's input  ;D
