Want to replace stock 1150 oil cooler lines

[Guest]

I want to replace the lines on the 1150 oil cooler I purchased some time ago. It is a long story, but basically I need to replace them, and I want to keep the banjo fittings that connect the stock cooler to the stock connections on the engine case. I am open to ideas, although SS would be the obvious choice. It is the banjo fitings that I am finding difficult to find in their original size.
Thanks in advance.

I went there, and this is the problem:
First, the thread size of the stock system is M12x1.00. This thread size is apparently uncommon. The site has M12x1.25, which I have just verified will not work.
Second, there is a shoulder on the factory bolt, it measures ~13mm or 0.548". The site has one fitting which they say fits 0.570 or 14mm banjo bolts.
Has anyone done this conversion before, and if so, what did you use?
I have lots of -6AN stainless hose lying around that I could use if I could find the correct fittings.

Either:
get an adapter plate for the filter cover so you can get swivel adapters that screw right in or

get a nice set of OEM 550 lines off of ebay. The 550 lines are a little shorter but my relocating the cooler a little I was able to make it work.

Finding a banjo fitting for those front ports is going to be tough I think. Aren't they 14mm anyway?

I saw one of those butchered filter covers on an otherwise pristine bike. I nearly puked.
The threads on the bottom banjo bolt are 14mm and the top are 12mm, but with a step to make them 14mm where the line fits.
Turns out we have an Earl's shop here in Indy. I went in there and explained what I was doing, and he hooked me up with no problem. I picked up 4 banjo fittings for less than $60, tax iincluded. They have a 14mm hole for my existing banjo bolts, and take -6AN SS hose, which I happened to have laying around. Now to just build these wee beasties and get them tested.

You didn't happen to get a part number for those parts, did you?

[koolaid_kid]

Funny you should mention that. I looked at the receipt when I got home and the part number is listed as "8076XX".
I have been looking on-line and have found similar, but not 14mm banjo to -6 AN hose. I found this on Summit's site:

http://www.summitracing.com/parts/EAR-807691ERL/

They took a kit like this and pulled out the banjo bolt and crush washers, selling me just the fitting. But the Summit fitting is 12mm to -6AN, and I measured the fitting I have with my cheapie digital caliper and it is definitely 14mm.
You could call them, here is there web site, but it is useless except for their address and phone numbers.

The manager there seemed to really know his stuff, and he might be able to fix you up over the phone.

WOOOOHOOOOOOOOO!

No more money shots, eh?



Indianapolis is the motorsports capital of the world, but it can be ass-grindingly difficult at times to find the supplies and expertise that you KNOW are around here somewhere -- you just gotta know a guy who knows a guy who knows a guy who will tell you his life story before revealing the secret location of a little unmarked shop with broken windows behind a dumpster at the back of an alley. Fortunately, the secret of Earl's is a bit better known. But only a little.

For example, I spent most of the morning looking for a machine shop with a hydraulic press to replace a wheel bearing in a car (don't ask) -- I went on three wild goose chases before the fourth panned out. You'd be amazed at how many busy shops don't have a hydraulic press, and apparently have never heard of such a crazy thing as replacing a wheel bearing...

Brian is the guy who told me his life story, then about earlsindy. Thanks Brian.
I had to wait a bit, the manager was flirting with a piece of eye candy while the guy waiting on me was totally lost. When the eye candy left, the manager came over and got me fixed up right away.
Here is what the piece looks like, but it has the banjo bolt also:

Update: They are done

Finally got around to finishing the project. Took a couple (well, 3) tries to find the proper length of the stainless steel lines so they would not touch the header pipes or have too much line just "hanging around".
Center View. I zip tied them to the frame crossbar and to each other so they would not hit the header pipes.



Bottom view. Because the fitting was larger than stock, and the lines were as well, I had to route them outside of the factory "U" where the stock tubing fits. Otherwise, they interfered with the oil filter, which would be a bad thing.


Top view. Although you can't tell from this angle, I made them as symetrical as possible, which required multiple attempts to make them long enough but not too long.



Please pardon my dirty engine. I changed the oil and started it to check for leaks, but have not taken it for the intitial cruise, which will be followed by a thorough cleaning.
And Brian, Tim, Joe, etc., no more money shots.

Just a note, if you have not build SS lines with Earl's fittings before, it takes a bit of practice to get it correct. The result is worth it IMHO, because I have never had a properly assembled line leak (yet).
