NCR oil cooler install. now with pics

lofty55 · September 10, 2010, 03:50:50 PM

Just received my new cooler today. I'll be installing over the weekend. The plan is to unbolt the stocker and raise it as high as I can so the oil runs out. Then swap in the new lines and NCR cooler and top off with a little motul.

Anyone else done this or see a problem with doing it this way?

Thanks.

Sounds reasonable to me. What are your plans for the oem cooler?

Too much oil in the crankcase is a bad bad bad thing -- can happen if you drain the oil cooler back into the case. Highly not recommended to do!

Just remove and then drain existing oil cooler into something clean. Add drained oil to new cooler if possible BEFORE install. Attach lines. Fire and let idle for a minute or two -- then bring to temp. Check oil and add as necessary. Double check oil line fittings after a heat/cool cycle. Then enjoy the ride. Check the oil level after @50 miles to make sure no surprises.

Above shouldn't take more than an hour maximum? So do a before / after temperature test on the same riding route to see if you can see what difference the oversized oil cooler makes. Nice back-to-back verification and lots of Ducatista would be interested to learn as well.

Pay attention to torque values/feel and proper wrench placement. Oil coolers are surprisingly fragile - ask me how I know! Also watch for torn o-rings on the lines and insert carefully. Don't rush things.

Oem leaks. Part of the reason I replaced it. I'll keep it for a rainy day though.

Big thanks for the tips. On a hot day and longer ride, I usually see the temp plateau around 230 as long as I keep moving. It was a little hotter before my exhaust and intake upgrades.

So here is what I think ill do. I'll let my bike warm up to 230 (or something close), then take a route with no stops (freeway) for 10 minutes or so and see what the temp does. I'll swap coolers and repeat. Hopefully I see a difference. If not, I guess I get bragging rights to the only NCR part on my bike

When I told my mechanic about trying to get my bike to run cooler, he sort of chuckled and said, "good luck, those ds1000s get HOT." As we all know.

Pics to come.

230 isn't hot. That is what my bike will run if it is hot out(around 90 degrees F). I'd be worried if it was closer to 300 or above like some of the 695's were a couple of years ago. Those bikes were turning the cylinder and head paint brown because they were running so lean.

Mine too. That's why ill let it warm up to the normal 230 then hit the freeway with the NCR to see if it improves. How much will my engine and oil love me if instead of 230, I get it to plateau around 180, as others have claimed?

The Oem quickly hit 209 on this mornings ride. I'm about to swap in the NCR.

230 seems about right.

SR: How hot is too hot for engine oil?
Ed: This usually depends on the oil being used. For example, synthetic oils usually have the ability to withstand higher temperatures than conventional oil. As a general rule, engine oils will begin to degrade when the oil temperatures begin to reach 250 degrees F, though premium synthetic engine oils resist this breakdown to a much higher degree due to the uniform polymer chain and superior additive package.

SR: Is there a minimum oil operating temperature?
Ed: Normal oil temperatures are going to be between 200 to 220 degrees F in most engines. It needs to evaporate water condensate that may have been built up in the system due to hot engine oil cooling down in cold ambient temperatures.

You're going to want it over 210'F. That way, the condensation in the oil can boil off and not stay in the oil. Repeated temps over 210'F are actually good for the engine...
