Refer to the above post regarding the flywheel from an M130 to M180.

The bad engine is M180. The new engine is M130. I want to use my existing transmission on the M130 engine. The transmission in my photographs above is a spare for which I also have a clutch and pressure plate.

The next thing for me to do is to pull my M180 engine and transmission to see what will fit on the M130 engine. I was hoping to get some foresight before I tore into the project. I don't want to get half way taken apart and not have something critical like a transmission or flywheel. The engine transplant will be done at my job where they will tolerate my personal car for one day, but not a week.

Ok,

got it now.
you need the flywheel to suit your new engine but the Spare trans can be bolted straight up to your new engine .
Before you pull the old engine and trans you need to find a flywheel.

You now know that the trans in your car will be the same as the spare trans but with a different top plate. Those floor change mechanisms are a pig to drive so you re right to keep the column shift.

The earlier 190SL top plate with built in shifter is a better trans to drive with but you don't need this.

So..once you have the Flywheel and spigot shaft bearing for the rear of the crank,to suit your new engine you can bolt the two together .

I still think that the flex disc required for the rear of the trans will be bigger on your spare trans so you need to get out and get under ,then measure the bolt centers on the cars flex disc.
Compare it with the spare trans flex disc spider . To save hassles I would just bolt the bell housing from the car onto the Spare trans and reuse it.
That way the speedo drive will have the correct ratio etc etc .

make 100% sure you change the bushes in the two top shift arms . if you dont I guarantee they will fail and you will find gear shifting next to impossible.

lastly You will never do an engine change on a finny in one day ..hire a engine crane and do it at home or get a job where they cut the employees some slack .

If the trans in the car will be the same as the spare, why can't I use the trans that is in the car now? Can I use the flywheel that is attached to the M180 engine?

I just happen to have an extra 190SL transmission in storage...

Not the one that is in your pics,thats a torque convertor and drive plate . it performs a different function.

i would like to buy the shifter off that 190 SL trans... but i am restoring my ponton back to stock which means column shift only

JeffreyNMemphis · #50 07-03-2010, 07:14 PM

That picture is the M130 engine. I understand why that flywheel will not work.

Later on the same car, I swapped out the M180 motor to the M130. In that swap I used all the same stuff from the M180 motor, ... I don't remember changing the flywheel , but I think I must have because the older M180 crank setup was different and the balancing of the flywheel was done on that crank assy prior to crankcase assy.

In your case, I would just take the rear plate off the engine of your M180 motor and bolt it to the M130 motor, and likewise take the motor mount arms from your M180 motor and put those on the M130. The flywheel on the M180 was guide pinned and had 6 12mm bolts. I think the M130 has 6 bolts too. If the flywheel will bolt up to the crank, then bolt it up and try it out.

The pilot bearing is no problem, just buy the bearing for the M130, which I bet is the same as used on the M180. Pull the one out of your M180 and check it out for fit in the M130 crank. I just checked out the pilot bearing between the two motors and it supercedes to the same P/N: 1159800115. The cover ring is probably the same also.

At worst, you may need the manual trans flywheel for the later 6 cyl. I think that one from any of the 7 main bearing 6 cyl crank designs would work. In those the flywheel was no longer balanced to the crank assy prior to assy, but pre-balanced as a unit. Then you didn't have to deal with balacing to the motor in replacement.

This means you need to pull your exisiting engine and trans.
remove the trans from the engine.
remove the flywheel from the M180.
Hold it against the crank of the M130 .
Do the holes line up or not?
If they line up ,bolt it in place and install the spigot bearing and clutch. center the plate and and fit your cars trans with the different bellhousing .

I love this Forum. I learned something about the design of the M180 engine that I could never have guessed and could not possibly have observed when I took it apart. The engine crank is balanced with the flywheel as a unit with the harmonic balancer. The bolts on the flywheel are also a different size than the M130. The flywheel counter-balances the crank on the M180. The M130 is balanced internally, so the M180 flywheel would have a vibration from the counter-weights.

The Emerald Bullet was transported with the donor engine to the shop today. Tommorrow the motor swap gets underway. It should be running soon!

JiveTurkey · #54 07-16-2010, 06:47 PM

Congrats Jeff. I bet you're eager to get that old beast back on the road eh? I think Wilma and Emmy need a linkup at some point.

JeffreyNMemphis · #55 07-18-2010, 04:15 PM

Hello Peaches,

I snapped some pictures of the motor swap.

With the engine out.

The old engine with massive hole.

The donor motor...

The game plan is to go over the donor motor to make sure things like the oil pump are working correctly, then swap all the peripheral parts off of my original motor. I had just installed a new water pump, AC condensor, alternator and rebuilt the carburetors.

The heater tap is an interesting addition...

I have always wondered what that could be for? Maybe my heater cores are leaking.

mercmad6.3 · #58 07-18-2010, 09:46 PM

The heaters will be OK,they last forever. it is more likely to be the taps under the heater box. there are two and they stick. Do a search on this forum for hints on how to free them. I always do it with a hot engine.

Worked last night for a few hours. The 10mm allen bolts that hold the flywheel on won't come off nicely. The metal is soft and won't allow grip or impact. We tried everything we could think of then stopped before we hurt something or someone.
