WTB a W114 230.6 Pullman

Saw a 230.6 Pullman a few hours from where I live for sale. It's close to where family of mine lives also, like 30 minutes from them. Car costs around 2400 Euros, and it's completely dismantled, all parts are removed. The car was already sandblasted (to the case for body parts apparently) and has already a primer on it. There's some welding work left to do.

All parts (+interior) included. Not sure if everything works, according to the seller the car worked fine before he started dismantling it.

Car had an ugly green colour that just doesn't fit with a pullman…*would repaint it in another original MB colour but not this one. Hope it doesn't lower its value.

I have yet to finish my 220D, but I'm attracted to this deal somehow. Anything I should look out for, or anything I should ask? Any parts that are expensive/hard to get for the Pullman? I'm thinking of rear doors, rear door interiors, chrome bars at the back, some of the seats… anything technical like wheels, brakes, etc. that is different on Pullman cars compared to a standard 230.6? Anything to look out for with normal 230.6's to begin with?

Thanks

PS: Just noticed "Pullman" is the wrong term here. I guess it's just a V114, or "230.6 long" or something like that.

Wheels will probably be 15" instead of 14" but it doesn't matter. Any body part that is unique to the LWB cars will be difficult to find. I like those cars also, seldom seen in the states...

15" wheels shouldn't be a problem, I actually hope they're included. I'll make sure any unique LWB parts are included, especially interior parts also.

Two little things that could be a danger:

The car has hydraulic assisted steering (could pose problems and apparently very expensive) and a self levelling suspension. Any more tips what to look out for, especially regarding these past? Read about about the assisted steering, but couldn't find any tips or hints on what could fail on the suspension.

1. Do you mean power steering? Different from other power steering?
2. I didn't know that SLS existed in the 114/115 era. Is it the same as W123 SLS (on wagons)? Rear only? I have no idea if the parts are the same. On a 123 it's wonderful. There are things that can/will go wrong with it but they aren't insane to replace. Often the valve will start leaking and the accumulators will fail, resulting in a rather harsh experience when you go over a bump.

Yes, power steering!

As for the suspension, at least I believe it is this. It's called "Niveauregulierung" in german, so I think it's the self levelling suspension. I'm not sure if it's fron or rear or both, and if it's the same as the W123, but I found this here and it also fits 123's apparently:

SACHS Stoßdämpfer hinten Niveauregulierung Mercedes /8 W114 W115 C123 W123 | eBay

Quite expensive… I've seen some cheaper stuff but also some more expensive parts. What does this SLS consist of? Is it just these parts that are on eBay or is there something else part of "the system"?

Oh and yes, I heard about the leaking. Can these parts be repaired easily or do they usually have to be bought new? What are the accumulators and valves called exactly, so I can look up their price?

It's the rear suspension. It consists of a hydraulic pump driven by the engine that recirculates hydraulic fluid to the rear suspension and back to the front tank contentiously. There is a leveling valve that adjusts the ride height of the rear end based on where the car is sitting. For example, (using a US W123 station wagon) you have the car turned off on level ground and the car is level. You open the lift gate and 3 fat men sit on the back sill of the car. The car is no longer level. You start the car and the valve is now in a position where it knows that the suspension is too low so the valve sends more fluid to the hydraulic struts raising the car to a level position. Then the three fat guys get off the back of the car, that changes the positioning of the valve and it lowers the fluid to the hydraulic struts, again making it level. In between the valve and the hydraulic struts are hydraulic accumulators (spheres). These are spheres with a diaphragm - on one side of the diaphragm is nitrogen (I think) and on the other side hydraulic fluid. The diaphragm is not rigid - if you were to poke on it (through the hydraulic fluid opening) with the eraser side of a pencil you would feel the diaphragm and it would give a little. This is what makes the ride smooth. When an accumulator fails it is because the diaphragm has broken, meaning there is NO give in the fluid pressure. So if you go over a bump the suspension immediately responds by first sensing that the car is too low and adding pressure, then sensing that it is too high, relieving pressure. The result is that the back of the car can kind of jolt / hop when going over a speed bump. It's unpleasant. The jolt will only be on the side of the car that has the failed diaphragm.

The common failure points of the SLS are the valve and the accumulators. The valve will start to leak and it can be rebuilt (and it is not expensive to rebuild it). The accumulators you replace.

One of the discount auto places on-line lists the price for an accumulator as $110. The price for the hydraulic strut is $239. If you want to look at other prices, go to autohausaz.com and put in for your car search a 1985 Mercedes 300 TDT (it won't recognize the older non-US 114/115 car). The click suspension. Then click the part you are wondering about.

You replace the struts if they leak. You replace the accumulators if you get a big bump when you drive over a speed bump. You rebuild the valve the car sags overnight or otherwise just doesn't level itself.

Then in the front of the car I have no idea what you do -- my car never had issues in the hydraulic pump or tank.

It's a really nice system and provides a really nice ride. Very important for a car that will have varying loads in the back end...

The valve can be bought new (at least for a later car) but is extremely expensive. Rebuilding works fine. I used to sell rebuilt SLS valves on ebay, but I don't do that anymore.

The common scenario is for someone to neglect the car for years and you don't know what needs replacing. You find out when you start the car and observe the rear suspension. (making sure there is clean CORRECT hydraulic fluid in it. Mercedes sells it. Not cheap, not expensive.

Thanks for the great explanation!

It makes sense on the V114/V115, because you can have a lot of people sitting at the back (up to 6 people) + stuff in the trunk… I've just checked the original price list from 1974 (the car is from 1973 but whatever) and it was in fact an option, for all models/chassis, even for the 200D. Funny thing is that the original price was 666 german Marks.

Is there also a way to see if it's broken without driving? Because I won't have the possibility to drive with it, since the car is completely taken apart. It would suck to mount it only to realise it has to be repaired and take it out again.

Isn't this system only installed at the back? Or are you talking about the power steering?
