I had a leaking trans cooler line (the rigid line where the flex lines going to the trans cooler are attached) due to rubbing against the metal clamp that is held down by one of the bolts that attach the lower oil pan. The rubber had become dislodged and allowed metal to metal contact which eventually rubbed thru and I had trans fluid. dripping all over the floor (I caught it before it ran out luckily)
I had a local INDY (a good ole bowah to me!) said a new line would run several hundred $$ and take weeks ot geet it in the first place. He said he had successfully repaired the pressure side of rigind lines by brazing over the hole. Basically he disconnected the line, blew out all the fluid with compressed air followed by some acetone squirted in one end, then he wrapped a quarter section of larger dia. steel line held by a tie wire and torched it while applying braze material. Its been working fine for years. If the line is a return line you could work down a short section of rubber hose (or slit it) and clamp it tightly.
I suggest you avoid yanking the SLS, its a nice feature. OTOH, if you can get the right shocks (known to work well in a 300TD) and someone that has experience with the type of modification required, then its a possibility. I saw a W126 being modified from SLS to conventional shocks, there was a cutting torch involved. It was a lot of work, I have to think a wagon will be similar.

Dieseldiehard were you aware the hydraulic suspension lines carry over 1800 PSI?

You need good lines to hold that much pressure. Brazing in a new section of pipe might work but it would be easier to replace the pipe. The only rubber hose that would hold the pressure would be hydraulic hose. Much more costly than a steel line but might be the way to go if it is impossible to worm the new steel line into position.

Right On about the SLS pressure, a brazed section of steel over the steel tubing will carry all the pressure the original line was meant to handle.
I advised that any rubber splice must go around the return side, assuming it has to be less pressure because its vented to the chamber at the other end, unless there is a large surge when the SLS valve actuates. What do you know about the SLS return line pressure?

Randy do you know what vehicles the two wagon springs were specified on? I have always felt there is some difference between my '79 and '85 wagons in terms of softness associated with the springs. Handling too seems to be different as a result of the springs (they might just be soft!
Both o the wagos have new Bilstein comforts up front and new bushings, ball joints and control arms/track rods. The '70 is much better in handling than the '85.
Trying to correlate the data you listed (thanks much for that BTW!) I figured that the 123-324-29-04 springs will deflect 2.4" per 150 Lbs, does that sound right to you? That seems like a lot of travel to me. If I canget ahold of a spring I may try to check that figure. Converting Newtons (joules/meter) to cm then to pounds is tricky math and I'm not sure I got it right.
Anyhow,
The 123-324-41-04 springs calculated as 2.5" deflection with the same loading, not much difference!
The height difference between a sedan spring and a wagon spring might be something I have been looking for, I have a sedan that is sitting a littel high in the rear and I want to lower it by using the thinner spring pads, the extra 0.75 inch in height of the wagon springs might also be helpful, if I can find some wagon springs I'll be all set. This reminds me, I have a >new< set of 115 rear springs. Maybe I can use them?

The springs listed would be for the generic TD with the turbodiesel and automatic (123.193) so I'm thinking that would be models from 1981 - 1985.

It's hideously Byzantine but, all the info is here @ skinnerbox:

For anyone who cares, there's no major modification necessary when replacing the hydropneumatic struts with standard shock absorbers. They bolt right up. All one has to do is trim whatever length of shaft (on the shock absorber) that protrudes beyond the locknut so the interior panels fit properly.
Think I'm just being difficult? Come drive my car. Maybe you can help me adjust the gearbox while we're at it.... I wish my girlfriend would let me replace that with a less sophisticated unit, as well!

Instant Carma(sic) has caught up with me.

I walked out this morning to get in the wagon and go to work and guess what? There's a HUGE puddle of SLS fluid underneath her rearend.

GO figure...

I'm truly sorry to hear that, R Leo. When I bought my wagon in September, one of the struts was puking fluid, and both axles were shot. I had the rear end all torn apart anyway, so I just put the shocks on (I have a '77 230 which ended its LONG career - - 790k on the clock - - by donating said components to the TD). Also, I intend to use the stainless hydraulic lines from the hydropneumatic system as my fuel lines when I get my veggie system installed. I have all the stuff I tore off my wagon out in the shed. I was saving it, thinking I might restore the car someday, or buy another one to restore, but if you need any of the parts, let me know.

Jay.

Hi! I'm Randy. I'm a Benzohaulic. "We admitted we were powerless over Benzos - that our lives had become unmanageable."

Thanks mucho for the parts offer...I haven't crawled under there yet to see exactly what has popped (part of the wonderfullness of having several cars to drive & work on is being able look at that puddle, walk back into the house, grab another set of keys and move on).

I expect that it's one of the flexible lines and (I hope, I hope!!!) that it is one that I have a spare for since, a few months back, I bought a set of struts, accumulators and hoses from another forum member that was parting out a wrecked TD. The suspension components had been replaced about a year before the wreck...got the whole kit and kaboodle for $100!
