Anyone think that a pan temp in the 230s* is high?  Thanks Doc

I ran a Tru Cool tranny cooler on my 00 when I rode to colorado a year ago. It was very cheap and worked really good. I normally run an old Lockhart sportster cooler unless I go on a long trip then I go for the larger one. Tru cool makes alot of different sizes and they are well built and light. Jeggs and Summit sell them. Worth a look!!

 I am curious. Is it better or worse if you don't run the adapter or just run the lines back to the engine before it dumps back into the tank? I run an adapter because I want to cool my oil before it enters the engine. I have a friend who swears it runs cooler the other way, WTF. Just wondering if there is any data to prove if it even matters. We all want as much temp drop as possible IMHO. 

Rokin,
I can only relay what I've read from various manufacturers of coolers, but it is my understanding that it is better to filter the oil first, and then cool it. Everything I've read says that hot oil not only flows more freely through the filter, but also filters better.

For an evo... yeah.

My '02 TC would run 230-250 when it was 110+ ambient. Dry desert air results in higher combustion temps than you wet folks in the southest...

My '08... I'd love to see 230 in the pan.  I bet it hit 250 yesterday and it was bout 90 ambient.  I've seen 300+ in the pan when it's over 110... that was with oil cooler and XIED's

It is cooler the other way around but only because of where (oil bag?) it's being measured... think bout it.  You cool your oil before engine, it heats up and you measure temp in bag.  He heats oil in engine, then cools it and then measures temp in bag.  It's all the same temp going into both engines... right??  but go ahead and let him think he's cooler.....

So,  i should prolley add at least 15 to my '02 stats above to equally compare... but these new 96 TC's with '02 sensors are definitly hotter!

I would consider it high if the bike was moving, although HD considers it "normal."  Normal isn't necessarily ideal, however.  I've seen 230° several times in two years, only in summer while in stop-and-go traffic, always below 210° while moving.  I consider this acceptable.

One of the reasons I am considering going back to the crash bar oil cooler is that it was the BEST method for cooling my bikes' oil. Even with my dual oil cooler set up, the temps were in the upper 200s and bordering 300 while running hard across the Mojave last summer. Then again my bike has always run hot oil temps. In a couple of weeks I'll probably pull the Spurgin and go with the crash bar and the 10 row.

About 3 weeks back I put a Jagg on the frame down tube. Already had Harley's premium low cooler on it . Should have done this years ago , much better....xzo

Which brings me back to the baser matter of the situation. I often think that the oil cooler down low is blocked by the big fender and this does not get the proper heat exchange from a steady breeze. The ONLY time it dropped the temps below 250 is when I rode in the rain and the water provided liquid cooling on fins. I would like to run one on the down tube, but with my old style lowers there is not enough clearance, hence the Spurgin. On the other hand the crash bar is ALWAYS in the breeze. I'd like to see pictures of the Eastern Performance oil cooler with lowers to check out the clearance.

Look at the cooler fan combo in the post today by Jim B. "Oil cooler or Lenale fan" It works great!

I'm heading for the Laughlin River Run this morning, I'll look for more oil cooler options... Report back later in the week...

100 degree's yesterday, it's only supposed to get up to 99 today...

Anyone have a Davern Machine cooler? No internal fins. I bought two of theirs years ago for my 118" FXDL, but never got around to mounting them. They also sold [and I bought] a bypass block that mounts between the case and the oil filter mount. I can't remember exactly how the plumbing was routed to/from said block.

The Davern's look similar in design to the ebay Eastern Performance ebay coolers shown earlier;

Internal fins vs no internal fins?: I would think that there would be a big difference in cooling.

For plumbing simplicity, the filter mount with internal 'stat used on some of the SE bikes works nicely on bikes that can use it. I used one of those on my FLHT. One line to crash bar, one line back.

Dave, do you happen to have a part number for that filter mount? That is exactly what I would like to do with my bike.

SEE ya there TAB  .  Taking off Fri morning.

Dan,

I'll look to see if I still have the paperwork. Iirc, the MoCo sold the mount in a kit form, maybe in black or chrome. Iirc, you could also find it in the parts book for the SE FLH bikes with 103 engine.

email me in a day or two if I forget and don't post back.

Thanks, Dave.

Dan,

I sent you a PM about that cooler. I have one for sale. Forgot to mention in the email that the replacement mount is silver not chrome.

Got it and replied. Thanks.

Dan,

I replied to your reply but I don't think they ever made them in black, only silver or chrome. Never did understand why.

Anyone know where to get the best deal on a Jagg 10 row oil cooler for a bagger?

Jenny

I was taught never to bullhead a t either ...easy fix is to turn the t 90 degrees so the t will flow on the run and branch regardless of any pressure delta.

Hope it is done right.  Doc
