    I installed a Jagg oil cooler on my '96 Dyna Evo 5 years ago, no issues, no leaks & running much cooler. A cooler running engine is a longer-lasting engine.

    Not wanting to hijack your thread A1oz, but I thought I would use the title, I know that Lockhart Oil Coolers have gone out of business, years ago
    you used to see a lot of Evo's with these cooler mounted up high on the frame like the below pic (I know it's a pic of a shovel, before somebody replies) anybody know if you could do the same with a twin cam. 
    Is there a reason why the MoCo and aftermarket sellers have moved away from the lockhart style cooler and have mounted them either low down or horizontally on the frame rails. Could having to pump the oil up so high be a problem on the TC's.

    Cheers Benno

    I may be wrong, but always thought they mounted them high so that they would drain back down into the Cam case and then be picked up by the oil pump scavenger system.

    Do you REALLY need one though?  Whats actually driving the need to install one?

    I have run my 86 Evo with a turbo and NO oil cooler on 40+  degree days with no issues (using OEM oil)

    Tussuck, have you ever measured your oil temperature ?
    I think Evo's used to run a lot cooler than twin cams do.

    Benno, I think the low oil cooler mounting is just for aesthetics.
    The high mount is probably a better position, (less crap from the front wheel ).
    The Jagg style cooler is a double flow unit with more cooling abilty than the Lockhart.

    Tussuck : Only thinking of longevity, like most machinery there is an optimal temp, not sure what that is on a TC.
    Speedzter: Your opinion on the cooler being up high is exactly my thoughts also, just haven't been able to find one that mounts up high, I was also concerned that they may have went away from this mounting point for the TC's for some reason to do with the oil pump.
    Do Jagg make a high mount horizontal unit that mounts on the frame gusset up the front, I haven't managed to find one just yet.

    good points...  So Oil temp is the issue then.  For an older bike running Dino oil that is an issue as the safe operating temp range is lower and narrower when compared to say Harley Synthetic oil.  The whole premise was to keep the oil in the safe operating range to ensure it does not start breaking down which would not be good for the engine.

    It would not hurt to research oil temp characteristics etc as you may find that with modern Synth oil temps are not such an issue.

    Tussuck, yea mate I do as the 117 doesn’t like city riding with the stop start traffic and I don’t like it when it starts to idle (fire) on the one piston

    Ahhh...well then that serves you right for have waaaay too many cubic inches in the engine!  lol

    I could do with keeping my engine cooler, and if not for the engine, then for the rider!  Traffic again today, could feel that twin cam radiating and that's before the weather warmed up!
    If not an oil cooler, what do you all think about a larger oil pan to get the overall temp down?

    The reality is cooling the oil won't do much for lowering cylinder/head temperatures in a Twin cam.
    If you've ever seen the amount of oil delivered to the top end, you'd be shocked how little there is.

    If your crawling in traffic, what will help is using some sort of cooling fan that directs air over the cylinders/heads. 
    Another piece of the puzzle is a good tune.

    Hi Guys,
    I looked at this when I first got my Dyna LowRider in 2016, I had come from Jap bikes and was surprised at the lack of oil cooling compared to these types of bike, ever the mighty DR650 which I still have has an oil cooler. 

    Its really an issue in slow hot traffic where there is no air movement. I did some oil temp measurements and was going for Jag originally but wanted a side mount. I saw a guy once put stone through his low mount oil cooler near sofala.

    Im sure the Jag works really well but even the little Harley one made a huge difference to the oil temp, I cant believe its an after market part on the larger TC's.

    Regards

    After my previous glowing endorsement of the Jagg oil cooler, today the whole filter housing worked it way loose on me whilst riding. Luckily was just arriving at destination, oil blown over exhaust, back wheel, rear brake, bulk of the oil came out whilst stationary. Central threaded adapter/reducer found loose, removed all Jagg filter housing & screwed filter back on original stock housing (my tool roll saved the day again).
    Looks like I should have utilized a bit of Loctite!
    Will reassemble, live & learn.

    Add it to the list of things to Loctite and periodically check; perhaps not so much a Jaggs thing, more a Dyna personality thing.

    Yeah, Jagg cooler is a good product, just these rubber mounted engines shaking around.
