Driveshaft Identification

dandeluca · Mar 23, 2022

So I purchased this driveshaft as part of my m46 swap for my 240. However now that I know a little bit more I am sure it is not an 240 m46 driveshaft.

Can anyone help me identify it.

The front of the driveshaft is about 24" long to the bearing.

and the rear of the driveshaft has a rubber guibo mount.

Thanks!

That front driveshaft half is looking like it's from a 740 to me. Looks too long to be a 240 version from the picture.

I suspect it is from a 740 m46. It is really long I don't think it would fit an m47 240.

Honestly its just a random guess though.

Anyone need an 740 manual driveshaft?

The part numbers are stamped near the end.

So it?s barely legible but the part number seems to be 3502043

So a 240 m47?

Not many google search results for that one.

is that a "lip" or ring near the bearing?

ummmmm

Whatever this is.

Looks like a 240 style center support bearing to me.

Although the necked down section says BMW, so the jury's still out.

Well I installed that bearing, but it matches what was there. :-P

Yeah, the parts catalog shows that's a 240 M47 shaft.

740 with Getrag 265 five speed transmission. 28 1/2 inches.

240 with M47 and it is 24 inches.

740 with M46 and those are 20 1/8 inches.

740 with M90 and it is 29 1/4 inches.

They are all guibo connectors to the tranny.

I think we have a winner. 240 m47 driveshaft with guibo connector. I'd like to thank everyone for playing.
