Hey everyone, recently purchased a 1970 with 67,000 miles on it without any knowledge of them. I've been reading a bunch of posts on the forum and I think I might have bitten off more than I can chew/afford. As far as I know the car had been stored for an extended period of time because it needed new air bags, but it sounds like it could be a lot more than just the bags.

The car looks nice but it really shows its age when you start to look closely. The interior is in good shape but the cream leather seats are dirty, possibly stained.

Where do most people go for their parts, new/used?? (Air bags, climate control levers)

Are there any service manuals or parts catalogs online??

Is there anything that needs to be changed/checked before driving it? I think I read something about a rubber line for the transmission cooler?


Thanks in advance!

....and a photo.

Joe, it looks like it is down in the front, which is fixable. Stick with this forum and ask your questions as they come up. This is the best place to get the answers you need. NOTE: The annual convention is to be held in Portland, OR, in late August. This is a great place to learn and meet fellow enthusiasts. Hope you will attend.

Portland would be just over 2600 Miles each way. Might have to wait and see where next years is held.

Welcome. You must have had a reason to buy the car with "no knowledge of them". Why did the car need new air bags - they are extremely durable? Cleaning dirty leather is a very simple and cheap project if a bit tedious.

When you say it has been stored for an extended period, how long is that? If it is only a few years - 4-6, that should not be a problem. You should just siphon out or drain the old fuel if there is more than a very little in the tank and put in new fuel. If it has been sitting for more than two years, replacing the brake fluid would be wise. Same thing regarding the oil and coolant. None of these things are any more expensive than any other car. The ATF is pretty durable. If it has sat for 20 years, that is another matter.

Do you know why the previous owner stopped driving it? That is an important thing to know if it is available.

A lot of us get parts from the Classic Center in Irvine California. I believe that US style aircon levers are not currently available. I believe that the Classic Center has digital service and parts manuals and financial membership of this organization or other Daimler affiliated club also gives you access to the Daimler EPC [electronic parts catalogue].

Probably the most important thing to ensure works properly before you drive it is the brakes - two ton of car does not stop well if the brakes are bad. I'd be replacing brake hoses before worrying about transmission cooler hoses. Replacing fuel hoses is sensible unless you know that they have been replaced in the last 10-15 years. The return hose at the back of the engine is the one that is most likely to have not been replaced and a fuel leak there is a hazard. It is not the easiest hose to get to! Are you mechanically minded or have a mechanic? All these things are relevant with regard to what you can chew.

Welcome!

Art has good points. It is very helpful if you would know the history of the car. In my rescue topic there should be good information, I am not saying I did everything the absolutely right way but you get some idea.

http://www.m-100.co/forum/topic.asp?TOPIC_ID=4307

And on this youtube-channel there is a lots of very basic information:

Thanks for the quick replies!

The friends I bought the car from don't really seem to know much about it. It sounds like it was a left over of their grandparents estate that had a collection of cars(40+). This was their grandmothers personal car and was registered under the family business since 1982. I found it under a heap of dust at the back of a warehouse while there to purchase a 2010 Subaru and just fell in love with it.

I believe the car has been stored indoors for the past 5-6 years. I was told they stopped driving it because of problems with the air suspension. That it was too expensive and too much work to fix. They said the air bags needed to be replaced.

There is a good chance it had a fuel stabilizer added considering how many cars they used to have. Is there a drain on the bottom of the tank? or will a hose go straight down the filler neck?

My knowledge of cars is limited mostly to early 90s Japanese 4 cylinders. The most I've done is upgrading head gaskets and a couple motor swaps. I hope to do the majority of the work at home in my garage. I would like to keep the car as original as possible, if affordable.

Thanks for the links Kari, I will check them out.

These are the controls that need to be replaced. They're too brittle to touch.

Welcome to the forum. I just purchased 3925 (1970 model as well), so it is exciting to have another fellow newbie. Happy to compare notes as I have had to do much work on my car to get it in good shape. Folks on this forum have been very helpful to that end.

And sorry, to answer your questions, Neil at Star Motors in Endicott NY and Tom Hansen at the Mercedes Classic Center have been instrumental in supplying parts. If you have replaced a motor before, you should be able to tackle most issues that come up on the 6.3. Parts are pricey and clearances tight for some parts replacement, but all do-able. And in addition to what other parts others have recommended replacing, I would consider doing all of the radiator and heater hoses, as well as the thermostat and thermostat housing gasket. Some of the heater hose is just bulk, cut by you to fit. I would also replace the transmission cooler lines and power steering low pressure return hose, and the flexible brake lines going to each caliper. Unless this car was unusually well maintained prior to it being parked, these are all items that deserve to be changed every ten years or so. Lastly, grease all the grease nipples including those at the rear brakes and differential. If they are dry and you start to drive the car, noise and havoc can ensue...

Ed --before driving the car, all rubber fuel hoses & fuel filter must be changed out --don't need a fire!---if the car hasn't been started, flush fuel pump, fuel tank, metal fuel feed and return pipes and fuel injection pump separately utilizing an auxiliary electric fuel pump. As Andrew stated all brake flex hoses should be replaced --will save you having to replace brake calipers and rotors due to brake drag -exercise the brake caliper pistons while you are at it -insure freedom of movement.

PS -on more than one occasion, I've had the fuel return tube at the fuel tank plug and have run a wire through to clear the passage --check this while you are doing the fuel system.

Welcome to a fellow Canadian!
Unfortunately choices to buy classic Benz parts in Canada are very slim to none.
I buy some of my generic K Jet parts and such from www.autopartsway.ca. They have great service and ship free. But you will struggle to find any 6.3 parts on there.
So yes for us Canadians, the MB Classic Centre is pretty much the way to go. That and ebay.
Now with our dollar in the toilet this hobby is really going to bite hard in the pocket...
For air suspension support, contact Martin Werminghausen, he is the recognized expert on the Benz air suspension.

Hi Ed. Regarding your ventilator slides, two of the four are currently available from Mercedes. The part numbers for each are as follows:

000-833-15-40 (not available right now)

000-833-16-40 Available

000-833-17-40 (not available right now)

000-833-18-40 Available

You're obviously wanting to stick to originality, but I'll mention this anyway. An aftermarket company, FEBI, makes these ventilator slides. They work well and are cosmetically correct on appearance, but the blue and smoke coloured levers are off on color....when the light up, that is. If you can live with that, then follow these links and you'll get all of what you need:

Thanks for all the info guys. I found an old thermostat in a new parts box in the car so it looks like it's had some kind of recent maintenance.

Aaron thanks for the info on the sliders. The ones that are "not available right now", does that mean they're expected to be back in stock some time soon, not likely ever again, or no one knows?

Ed, it's a guessing game. I can't imagine something like these heater controls not being made again, as they're a "replace every 5-10 years" item. However, Mercedes has called it quits on a lot of necessary items lately. Their rule of thumb for parts is if it doesn't take the car off of the road, they won't give it much consideration. I'm sure they know that FEBI is making them, so that's even more reason for them not to make anymore of their own.

Another problem is that when they do re-manufacture a part to meet a demand, they jack the prices up double, triple, and often more than the part cost before it ran out of stock the first time....and not because it actually costs that much more to make the parts(s), but because they simply can.

In the next 5-10 years I imagine that 3D printing will have been perfected to a large degree, and if that happens, then Mercedes will probably exit out of the classic parts business for the most part. The future is definitely grim looking. But......if 3D printing takes hold then ownership and actual purchase costs will probably subside a great deal.

One last option I'll offer to you....I do this often for customers that are as picky as you and I are. Buy a set of the aftermarket FEBI heater slides, remove the rubber handles, and then transfer the rubber handles on to the original slides. The rubber part is only riveted on to the hard plastic part with brass rivets. It's a very simple job, and when you're done, it still looks like the originals. :)

If we're putting on our originality police hats, I should point out that the radio is a late 1970s item. It "looks about right," but this car would more likely have come with a non-cassette radio.

Aaron do you just drill out the old rivets and then rivet the rubber onto the old plastic pieces?? Is it easy to find that rivet size?

Are all four handles the same?? Could I buy four of the cheaper red ones and use them for the blue and grey since they seem to be more expensive??

Late model radio huh?? That kind of reminds me, I think there are aftermarket speakers on the rear parcel shelf that don't look OEM.

Hi Ed. No, all 4 handles are not the same. And yes, rivets that small are able to be sourced. Drilling the old ones out is one way, or you can file the head off of one side of them with a hand file.

While I, and many others, can appreciate your trying to be resourceful in wondering if it would be less expensive to buy all of one color (which would be soooo incorrect) I have to say that mindset is futile to your ownership experience and the cars well being. You cannot cheap out. It's immoral, and will cause you many headaches. "6.3" and "resourceful" just can't belong in the same sentence. ;)

Regarding your radio, Mike is correct. Though, many upgraded to a cassette type radio in the 1970's. If there is paperwork documenting the upgrade, which will match the radio's serial number to certain paper work and warranty cards, then that';s usually acceptable. If you do, in fact, have aftermarket speakers in the rear, then never fear. You can still buy original speakers and speaker grills. :)
