R100 GS Oil cooler lines Question

Patrick C Buckl · 12-05-2012, 06:19 PM

Hi everybody,
looking to upgrade/replace the stainless lines on my gspd oil cooler. I have looked at the relocation kit from Touratech but really would just like new lines, probably aftermarket...partly for good looks and partly because mine have corroded quite a bit on the outside of the braiding with rusty grime and basic wear.

Any idea of the threading?
Could I buy a basic Pepboys aftermarket oil cooler line kit?
Does someone sell one already made?

Any help would be appreciated.

Any pictures of what youv'e done would be fantastic.

New lines are 125 from BMW. I have a lot of oil and hydraulic lines made locally and I doubt they could beat that price.

BMW's oil cooler uses a 16 X 1.5mm "Bubble Fitting" . This type of fitting is quite difficult to source and expensive.

Take your existing lines to any hydraulic place. They can disassemble the fittings & make up new hoses. I did that when I shifted the cooler off the crashbars & into a central position on the frame.

Be aware that the fittuings into the cooler can get quite corroded. I thought I was going to trash my cooler getting them off.

I put on rubber hoses (they are braided internally). Given the use I have put the bike to (4WD tracks, gravel etc), these are better - easier to clean. The picture is just after installing. They fit better now, once I put proper clips onto them in order to route them more neatly.

thank you for that and great pics. I actually have a lot of aircraft repair places around me of which many say hydraulic something or another so I would imagine thats a good resource for me.

Thanks a ton.

Another 50 bucks and your in Touratech Territory.

Pretty Sure the kit is $175

I;m pretty sure the Touratech lines are made by Motoren Israel in Germany so don't pay for the added mark up. If your local hydraulics shop can make you the proper lines cheaper then I would go that route.Remember your oil pressure go spike as high as 150 PSI.

Can you elaborate on the fittings on both ends? I would like to make up some SS lines for my RT cooler?

The banjo fittings at the thermostat are easy; you can buy two banjo adapters and straight hose ends or dedicated banjo hose ends for that location. The cooler ports are another story. I have found only one source for the bubble flares. These can also be had in an adapter and hose end or as a dedicated hose end. Oddly, the dedicated ends are available in black only. I have machined a hidden adapter but have not had a chance to test it.

How hard would it be to change the fittings on the Cooler out to AN?

Funny you should ask. I bought weld on -6 male fittings to do just that, and consulted with my favorite welder about the idea. He was in favor of it, but since I was planning on retailing this conversion, I shelved them. It would have required cutting off the original fittings and welding on the A/N fittings without leaks.

So yes, I think it's possible.

Hmmm, would I just weld onto the current fittings, or saw them off or what? I obviously am looking for a relatively clean look. That doesn't leak of course!
