Quick! 5 speed swap flywheel position notch

[cpandrewschmidt]

Hi all,
In middle of 5 speed swap. Keeping the Dual Mass flywheel. There's a little notch welded on it, i assume for timing. Does it matter where that notch lines up when putting the flywheel on? THx

BMW uses a locating dowel in between the crank and flywheel on one flywheel bolt to locate the flywheel correctly.

It only goes on one way when installed properly.

thanks, Im hoping i have it right then! the holes for that dowel all looked pretty similar on the flywheel. hard to tell but it did go one so I assume it's right

Like this.




One of the holes in the flywheel is larger than the rest to accommodate the dowel.

Wouldn't the flywheel position only matter on an E where younhave sensors in the bell housing rather than up front ?

[cpandrewschmidt]

good question, not sure. Bellhousing did come from an '87 e with dual mass flywheel. It has two sensors in the new bell housing. It's being swapped into a 91 325i vert.

I swapped an ETA 5spd into my Cabrio and we just cut the wires off the sensors and left them there to plug the hole. I also swapped to an RHD 7 lb flywheel which to my collection, was not machined for a dowel.

I just don't see what purpose it serves

[cpandrewschmidt]

Thanks Jeff, good to know I don't need those wires. I'm sure I would have been searching for hours to where they'd go!

Last question. Do I need to plug the holes on the radiator where the cooling lines came out for the auto? Don't want to start it up and have a mess if coolant will pour out :)

The transmission cooler section is separate from the main radiator, the only thing that would leak out of the holes would be residual transmission fluid.

I left mine open when I converted my car.
