Thumbs up Industrial Strength 617 Oil cooler lines - installed!

My dad's 300SD was recently under surgery for several things including a new timing chain tensioner, tensioner slide rail, upper guide, valve adjustment, crank pulley bolts replacement, vacuum pump inspection and gasket replacement, water pump replacement, water pump housing gasket and t-stat housing gasket replacements, coolant flush, oil change, AND Oil cooler lines replacement as the car still had the originals.

We took the old lines off, and had them fitted with 3/4" USA style hydraulic fittings....and had matching hoses of (almost) proper length made. They saved the old pipes and brazed the fittings on. The hoses are immense, and made from 750psi rated hydraulic/oil line. The crimps are huge, each line weighs at least a few pounds! Cost was about 1/2 of new OEM lines and they made them for us in 1.5 hours right here locally, not bad! These should last for-ever!

Some pics:

Great job, that should last a lifetime.

This looks like a copy (almost) of what I did 3yrs ago. I used parker Push lock hose instead. had the Hydraulic hose shop put this together for me.

had it with the old eng before the timing chain took it out, and 24,000 + mile with the new engine.

what kind of shop did the work? tractor repair? hydraulics firm? inquiring minds...

MB should have made their original oil lines this way - cheaper to replace, cheaper to swap out, probably only slightly more expensive to manufacture. Only down side is there are more areas for potential leaks. But the hoses themselves are simpler, and probably less prone to leaking than the current assemblies.

Parker and other companies make reusable hose fittings. You can actually buy your own hose (following the Fitting makers directions) screw the Outer Sleeve over the hose and screw the Fitting into the Hose.

But, those type of fittings are more expensive than the crimp on ones.

However, you need to use hose that is compatiable with the Fittings.

We had the lines done at our local ThermoKing facility, they run a hydraulics side business from their parts counter. The guy did a very nice job on the lines.....and it took him barely 1.5 hours!

Are they too stiff? Keep and eye on the oil cooler for leaks.

That should give you peace of mind knowing your oil cooler hoses wont just pop at any given time and an easier way to change it if you will ever need to(most likely you wont). Hose looks like the high pressure side hoses of the power steering pump.

They are somewhat stiff, but still flexible, and they get more flexible when warm....

I also eliminated the A/C compressor (it was locked up anyways)....and the compressor mount....which allows more movement in the main lines. This particular engine is not known for "moving" much, it has 0 side to side shake, and sits like a rock in the compartment....so there should be very little line strain.

That looks like an excellent option too. I would consider it if doing it again.

REALLY nice!

Does anyone know if the lines for a w123 240D are the same as a w123 300D?

I know the oil cooler on my 240D is different, but the lines can't be terribly different.
