Hey,

*bad spelling In title of post 'Whats' *

Im doing an engine swap in a 1990 325I bmw (main bearing dropped in my old engine) and I went to put the torque converter and flywheel back on the new engine and noticed that it wouldnt fit because of this difference...

Old engine... ************************************ New engine.....

[attachmentid=20906]************************[attachmentid=20908]

The peice that is in the new engine is already on the back of the torque converter... should I remove the one on the torque converter or on the engine? and how do you remove it.

thanks for your help. I really appreciate it

I guess I was too quick to ask for help.

I hammered a bolt into it until it was stuck *litte taps* then hit the bolt with the back end of a hammer and that baby popped right out

Isn't that what I call the pilot bearing? I just hope you know that you have to fit a new one in the place of the old one.

the engine you bought was out of a 5-speed, that is the pilot bearing for a manual

What you're looking at is the spigot bearing and is only used with manual gearboxes you can bolt the flexi-plate straight on but the torque converter should have been left on the gearbox when it was taken out. If it was your picture I say with the converter still on the engine you'll have to fit it back into the box before putting the two together or you'll damage the gearbox's pump. To fit the converter you have to stand the box up on its tail and drop the converter on then keep turning the converter till it's on all its splines and the dog drive for the pump make sure you get this right or it'll get very expensive!!!!!!! Sorry to write so much but this is important. Any help you need e-mail me through the site….

you can just take the converter off the motor and put it in the tranny when you get ready to put the tranny back in. Make sure you do get the conv. all the way in the tranny cause you dont want to have to take the tranny back out from under your car to push it in more.
