Swapping motors M127.984 vs M130.982

[Paul Robinson]

I'm in the process of swapping motors -M127 (manual tranny) to an M130.  I read with interest from the link below regarding unbalanced and balanced flywheels.  The M130 was mated to an automatic, but I do have a 280 balanced flywheel (plus pilot bearing & cover) which will allow me to make the automatic to manual tranny swap on the larger engine.  My question is, can I use the bell housing and intermediate flange from the M127 on the M130?  The parts number from the EPC shows the flange and the bell housing for manual transmission set-up to be the same for both motors, which gives me some confidence. But before I get parts all over the garage floor I figure that it might be better get some input from those who have been down this road already.  Thanks for your time.

Hello Paul,

Yes you should be able to change the flywheel and perform the swap. You will need a set of standard flywheel bolts for the M130 engine since the M127 will not work and the automatic M130 automatic flywheel bolts are the wrong length.

Thank you, Joe.  I just ordered the flywheel bolts, not cheap but that's the way it goes with these old cars.  This engine swap by the way is for a 1964 220SEb Coupe..beautiful car inside and out, but the compression is bad on the M127, and the warm running device is kaput (over $1000 for the WRD alone!).  Donor car engine (only 77,000 miles) is from a 1971 280S, so technology wise I'm moving backward with the carburetion, but hopefully will gain some reliability and driving longevity as a result.  Thank you very much for your help.

Actually the fuel injected engines are as dependable or better than the carb engine. However the injected engines can be a bit more costly or complicated to get put back right.

The twin Zenith double carbs with the automatic chokes on the 280S engine,   can be a little difficult to set up. Keep my email handy.

Thank you.  I will keep your email handy.  My experience is with the 190sl, not the coupes, sedans, or the 113.  If my questions ever get to be a burden, then please tell me.
This W111 car is the Winter/Spring project.  In addition to the engine swap (heart transplant), I will first be doing a rear axle swap (double hip replacement).  I spent the Fall refurbishing a 3.27 axle with new seals, plus new trailing arm and center support rubber.  Why did the Germans gear these cars so low?  Did they use these 4.10 rear ends to pull out tree stumps?

I actually pulled a tree out once with a MB. It wasn't a very big tree but it pretty much destroyed the car in the process. Walked away without a scratch.

 If you've ben working on 190SL's then you will know about carbs. The twin Zeniths aren't too complicated but they drink gas. I've soldered the main jets up and drilled smaller holes which helped out somewhat.
 
Don't throw away and of the fuel injection stuff from the coupe. I have good distributor blocks but I've used up all of my spare fuel injectors so I could use a full set or at least a few good ones.

I'm thinking that I will hold on to the M127, as well as fuel injection parts, relays, etc.  If I ever sell the car then I would prefer that the buyer to have the option of converting back to the original set-up.  Will certainly let you know if this plan changes (have not factored in the storage angst from my wife yet).

I have not had time to go over the Zeniths, so I don't know their condition.  If necessary, I was looking at twin Weber's as a possible alternative, although I've read that they can be finicky.  I'm running Mikuni's on the 190sl, which have been wonderfully reliable.  If only Mikuni made a downdraft!

So........ are you planning to keep her in the basement, or in the attic?

[Paul Robinson]

My wife is on to me, so I can not use the dining room again (the 190sl engine sat there for three years)....so probably the basement?

I hope it's not one of those Pulp Fiction deals.........
