Title: Oil Cooler Leak Post by: Duc L'Smart on May 25, 2008, 08:10:16 AM The ol' Paul Smart developed a leak in the oil cooler- No Bueno!
Here's the main thread- http://ducatimonsterworldwide.org/index.php?topic=2971.15 All suggestions most welcome [thumbsup] Title: Re: Oil Cooler Leak Post by: printman on May 25, 2008, 08:21:00 AM 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. Title: Re: Oil Cooler Leak Post by: Duc L'Smart on May 25, 2008, 08:23:19 AM 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?
Title: Re: Oil Cooler Leak Post by: printman on May 25, 2008, 08:41:55 AM 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 Title: Re: Oil Cooler Leak Post by: Howie on May 25, 2008, 02:30:11 PM 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.

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] Title: Re: Oil Cooler Leak Post by: Howie on May 26, 2008, 04:50:07 AM Of course not!

Anybody out there know if I am correct? Title: Re: Oil Cooler Leak Post by: Duc L'Smart on May 27, 2008, 07:33:54 AM 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 (http://homepage.mac.com/metcalfe/.cv/metcalfe/Sites/.Pictures/Weld.jpg-thumb_202_269.jpg) |
