W113: New Life Old Soul, Ch. 7 She's Out

 Had a lapse in progress, waiting on some necessary garage equipment that I loaned out a while back (engine hoist). So, now that I picked up my hoist, I was able to get the engine and transmission out and have the engine on a stand ready to get disassembled. There was a bit of work left to do before removing the engine, but it was about 20 minutes worth of work as I had everything ready to go. 

First thing on the list, remove the fuel hoses that were ridiculously old, brittle and one which was partially kinked. 



You can see how worn through the rubber hose was from having the hose clamp tightened beyond belief. 


Tachometer drive cable connection. Has a small kink at the edge. Nothing that would seem to prevent the cable from correctly driving the tachometer. Strictly cosmetic. 


Here it is removed. There seemed to be a small seepage of oil around this area, I'm not sure whether it was from the valve cover gasket, or the tachometer drive assembly.




Water temperature sensor cable



Engine ground cable, cable attaches to the transmission and to the bolt on the firewall. 

Removed the exhaust manifolds 

Here are the manifolds off the car and on the ground. Nice picture of these manifolds. At one point in time, a lot of work went into making these. The only problem,  someone welded the manifolds directly to the rest of the exhaust and did a poor job at that. The small bumps on the tubes where there should be flange, is partially welded and has been leaking exhaust for ages. You can see the blackening from rich exhaust. I'm sure the exhaust smell was pleasant driving with the top down. 

Here's the hole in the exhaust with a crack running around about 1/3 of the pipe. 




Seems like quality wire heading over to that starter lug, doesn't it? 

Skipping ahead 7 minutes, the engine was out. I didn't take pictures of any under car work. All that involved was transmission linkage removal, disconnecting the driveshaft from the transmission, and removing the two engine mount bolts. Once out, I set down some tires by the hoist where I can rest the motor while removing the transmission to get the engine stand pieces bolted to the engine. 


Here's the transmission. Tiny compared to later model cars and very light. Not something that will take gobs of power, but it's perfect for a car that's being cruised around in. 

Here's another shot of the transmission. This will be cleaned up nicely and will be nice and shiny silver once it's ready to go back into the car. 


Shifter bushings? There are none, nada. This car was completely barren of anything resembling a bushing for the shifter. How this car was even remotely driven is a damn wonder. 

Now with the transmission removed, we see the clutch assembly. It's a Sachs unit that was on the car. The clutch has life in it, but the flywheel and pressure plate has burn spots. Clutch was getting toasty at some point. 

I guess we could call this the starter plate. Bolted onto the engine block in 4 spots, then the transmission and starter bolt to this chunk of aluminum. 

Here is that plate removed. Seems the oil pan was removed too, there's a ring of orange RTV around the front and rear. I'm sure that isn't original, but I've seen crazier things. It seems to me that this engine must have been removed before - that or somebody was having quite a bit of fun trying to do this job with engine still installed. 

Disassembly station. Engine is on the stand and is getting ready for total disassembly. 



Engine number. Haven't payed much attention, but I forgot to check if this is a totally numbers matching car. 

Greatest oil filter housing ever?

  1. The engine is original. The M127 II or "127.991" is the specific engine for the 230SL. The "1" is for LHD cars and the "0" is for manual transmission cars. The actual engine number is 008 985.
