Question about engine

[Szymon]

Hi
Last week I bought a few engines for my prewar 170v. One of them is a little different. It has got aluminum head and lightweight oil pan. Gear box is different too, it could be modified. Can you please help me identify it? Is it pre or postwar engine?
Thanks

The engine is post war W120 1953-1957 (180 Sedan), maybe a few others.
A nice find.

Thanks

What about gear box? What model is it?

Is that welding around rear side of the bell? From the pictures, it looks possible, that a bell from W136 gearbox was taken, a metal plate welded on its back side and then fit on some gearbox /maybe w15?/.

The engine in question is from 1953. The date of casting is indicated on the cylinder block. Day, letter /the number of the letter in the alphabet means the number of the month/ year.

Yes looks also to me that the weld an differend gearbox on the bellhouse.
This engine does not fit in the 170 because of the shape of the oilpan.
That doesnt fit in the chassis

Does anyone know if you can simply interchange the oil pan?

Please let us know if it is possible.

I don't believe so .... the bolt hole pattern and number of bolts is completely different.  It also looks like the drive end on the engine is different also.

Hi,

This oilpan does not look like the 180-oilpans I have seen. I think it comes from another type of engine.
The 180 has an aluminium pan.

At my opinion you can use this engine block with an oilpan from a 170S.

You have to change the cover for the camshaft transmission.
If you use a chain transmission you can not use the 170S distributor, oilpump and camshaft. Wrong rotation direction.
You have to use distributor/camshaft/oilpump from a 170Sb 170SV or 180 first edition.
If you use a oilpump from a 180 you have to bend or replace the bottom part to a lower position.

And perhaps more.....

Good Luck !

Hi,

The part between engine and gearbox is normally made of aluminium.

This one is cast iron ? and modified to fit a gearbox I have never seen before

The cast iron bell housing may have been cut off form a transmission with the one piece transmission case and bell housing.
Although it is true that the camshaft and oil pump gear are different on the chain engine, I believe that the distributor rotation is the same. That's why the gear teeth directions are reversed.
