Can anyone identify this T/O bearing?

325i or dual mass 325e?

I think you have to take it out of the fork, and stand it up to measure it.

I have to measure the whole thing? I thought it was just from the mating surface to the fork to the bearing surface that mattered?

When I was researching what T/O bearing to use on my 323 fw, the comparisons always showed them standing up, to show the overall length. Though I don't know why the part in the fork would matter, the measurement you are talking about seems to be the more important one. Perhaps jlevie will pop in and school us.

Alright cool I will post a pic tonight. I need it for my m50 260 323 flywheel setup.

Any one with photo comparisons of the two?

I thought the throw out bearings for the e/i were the same.
They are listed on Pelicanparts as the same anyway. I bought a bearing a long time ago to replace with my e and then used it with my i swap. works fine and I could not tell any differences between the two.

Part # for an 86 325e TO bearing 21 51 7 521 471
Part# for an 1990 325 TO bearing 21 51 7 521 471


exact same man. :)

It depends on what flywheel is being used. If you have a dual mass you need a shorter T/O bearing and if your using a single mass you need a longer T/O bearing to reach the diaphragm because the whole assembly is thinner.

Maybe the difference is made up in the pressure plate thickness then.

Im just saying i pulled a random car 90 325i and 86 325e have the same part #

[Wishno87]

Just to follow up it was a single mass and the same as the one for an 89 325i that i bought.

They are the same. Was in the exact same scenario. Clutch works great.

that's because the '90 has a dual mass flywheel, earlier years of the 325i have a single mass.
