300SDL Resurrection
 
It's time I started this thread. I bought a 1986 300SDL on eBay in the winter of 2002-2003.

This was the sale picture of the car. It was non-running. All I really knew was the engine was blown. I had the car delivered and I trailered it up to my moms farm (we can't have non-running non-registered cars here) for later disassembly. The exterior of the car looks great. The paint is in like-new condition. However, the interior was very worn. The springs were shot in both seats, and the texture was worn off the steering wheel. My suspicions were confirmed. I don't think this car has 216k miles on it. I think it is more like 316k.

In June of 2003 I took out the engine and trans. Here is the engine out on on a stand. You can see a LOT of oil all over, and a hole in the block where the number 6 piston resides. In fact, you can see the big-end of the connecting rod in the hole. I took most of the engine apart and later that year I had the transmission rebuilt by a shop in Cummins, Georgia.

Most of the next 5 years were spent on construction projects and acquiring parts. First, I needed a block. A nice forum member donated a block wich I had shipped from Oregon. I got a whole piston set for less than $1000 on ebay and I also acquired all the seats and door panels from a '91 560SEL and a replacement carpet set. It looks like I'll be rebuilding the interior as well as the drivetrain.

I brought the car back home this fall so I could work on it here. First, I washed out the engine bay.

This summer I had the block resleeved and the crankshaft reconditioned. Then I got busy with rebuilding the engine in a 240D my son bought. Now that that one is done, I can get to this one. I put the engine on my engine stand last weekend and now I'm getting my connecting rods ready. I was missing an end-cap and another nice forum member sent me some. Now I;m mating pieces together and with some grinding tomorrow, will get 6 balanced connecting rods.

It appears that the engine was rebuilt for, or by the previous owner and the conrod end-cap came off. I don't know why. The bolts didn't break. There's nothing in the threads, which means they both loosened up and came off. Looking at the number on the connecting rods and end caps, it also looks like it was assembled with parts from multiple engines. Lucky me, they used a #22 head.

I look forward to following this thread. Keep the pics coming, it looks like a worthy car to redo!

Since I was waiting for engine parts, I decided to drive up to the farm and pick up the seats from a '91 560SEL that I bought 4 or 5 years ago. I got them and then took out the old broken down ones that were in the car. Here is a comparison of the front passenger seats.

This is the area of the car with the seat removed. You can see the four bolt locations. I've cleaned this area up a little. I found some change and a fuel receipt from April 2002. Maybe the last time this car was running.

You need to be able to move the seat up to get at the rear bolts for removal. The same with the fron ones. It helps to move the seal back. I used a 10.. socket with a universal joint. While the rear bolts are angled, you still can't get a straight shot at them.

These are the new and old driver seats. I like the newer style. They are very comfortable and offer a lot of support. Time will tell though since I haven't driven in one of these yet. The old seat had 4 broken springs and one of the broken springs had cut through a wire bundle underneath. I bet something didn't work. The new seats are heated, although I haven't hooked them up yet.

This is the driver side area for the seat. Same as the passenger side except for one additional connector, which thankfully were the same on both versions. I have new carpet for this car, but will change that out when warm weather returns.

Thanks. And no. I think standard was the square/rectangular slotted ones.

I am a bit green with envy. My 87 has the burgundy interior and it too has been rode hard and put up wet. I would love to freshen it up but the funding is drying up quickly. I would even consider changing it over to all black, if it meant i could find all the pieces for the right price. Mine is also in need of some body work.

Yeah, I've not had anything nice enough that I'd want to be seen in yet. I've been waiting until I get this thing done. Adam's a hard one to compete with!

Didn't we trade some 603 parts for some booze? :confused: :D

We might have. I had to acquire a lot of parts for this project over so many years I've forgotten where most came from.

You in Hell, Michigan? I can arrange it. I bought the instrument cluster for my Harley there.
