Alright heres the deal, i have removed all the basic crap to get the trans out.
You know exhaust, driveshaft, heat shields, guibo, trans mount, and like 8 or 9 tranny bolts ( i dont remember exact count).
So i pull the trans away from the motor and it gets about 1 - 2 inches away from the motor then just gets stuck. I can rotate the trans 45 degrees in either direction until the the bracket for the mount hits the tunnel. went i put the trans in gear and turn the motor i still spin the tranny, so i know the input shaft is still connected to the clutch. but i cant for the life of me figure out what i missed. i was reading the DIY clutch replacement and he mentions the bolt on the passenger side, i dont remember seeing it let alone removing it. I was at realoem.com and i was looking at the pic of trans (link below) i dont remember seeing bolt number 7.

Someone help me out.
P.S. i didnt read over this so i may have a few typo's.
-
Did you forgot starter motor?
-
That little bolt # 7 can be seen from the engine bay and from underneath the car. Can you take some pics of the perimeter of the bell housing so we can see what you've done so far.
-
I had the same thing happen, and it was #7...
-
its not bolt number 7, i removed it. the tranny spins clock wise and counter clockwise until the bracket for the mount his the the tunnel. the plate even moves until it gets caught on the dowel pins.
the starter is removed.
It feels like the clutch is still engaged. the plate that bolts to the guibo spins with the motor when in gear.
-
How high up above the ground is the car. Leverage to seperate them is key.
Does it separate evenly from the block 360degrees @ a few mm all over or is only at the bottom?
EXACTLY how many bolts do you have taken off in total.
I am guessing you either have one or two bolts still on the transmission causing this to happen?
We shall overcome this pesky issue :D
-
the car is almost 2 feet in the air.
the tranny is even all the way around when i put a jack under it to level it out. when it just hangs there is a big gap at the top of the bellhousing and the bottom rests against the upper potion of the oil pan.
i count 9 bolts but 1 maybe a brand new bolt. i ordered a few extra but im sure it was in the tranny it was marks on it las if i removed it with a socket.
i can take pics if you really want to see it but there are no bolts going from the tranny to block or vise-versa.
-
The weight of the trans changes the angle of the motor. Take the rear mounts and the bolt in support out also.
I'm a real slacker when it comes to this sort of thing. Get some metric all thread from Lowe's or Home Depot and cut it into 3"-4" pieces and screw it into the holes in the block. Let it support the weight of the front of the trans. Put a jack under the gear case part.
It's a real help putting it back in if you're by yourself. I lift it up onto the all thread and use that to support the weight while I align it at the tailshaft and shove it in.
-
i hear what your saying.
i had skinny pieces of wood i was using around the bellhousing. should i stick them back in between the block and trans and get the biggest prybar i can find?
-
Easy with the pry bar, the bell housing isn't as strong as you would think.
Is the tranny completely level or is the rear end "hanging/drooping" thus bearing most of the weight?
Use a floor jack to support the tail end of the transmission - don't jack it up too high and don't leave it too low.
While being very careful, while laying on your back, hold the trans with your left and right hands at the edges (almost like holding a steering wheel @ 9 and 3 o'clock) and put slight pressure while wiggling the tranny out gradually.
It can't hurt for us to see pics of what's going on as well, me might see something you're not seeing :p
I recently did a clutch on my 325i and I must say the smaller m42 getrag shouldn't be giving you any issues unless something isn't right which is rather odd :confused:
-
The tranny is level until i start to use a prybar to separate the two parts. then i would move the motor and change the alignment. so i stuck some skinny pieces of wood between the motor and trans and still no dice.
me and a friends tried laying under the trans but we werent completely under it due having it fall on our faces. im gonna give it try today and if still nothing i may just pull the motor out again. i had the motor out a few months ago with no probs but didnt have a funds for a new clutch back then( i wish i did, i wouldnt be having this problem). now i have the clutch and cant get the f'ing thing out haha.
ill post pics later.
-
Ya know, IIRC, even after finding and removing that #7 bolt, I still had a heck of a time separating the transmission from the engine. I think it may have just been that my angle was not quite straight with the motor, and the input shaft was binding on the clutch...
Again, IIRC, I think I had to jack the rear of the trans up such that it looked like it was TOO high, and pull evenly back, and it came right off.
The tranny jack helped immeasurably here.
-
i need to figure out a better way to keep the motor from changing position.
-
heres some crappy pics but its all i could get the flash was killing all the shots and its too dark without it.

I think I might have an answer for you...does it come off then stop abruptly, or does it feel like it is stuck on a big spring?
On my second car, lots of stuff corroded thanks to the PO, and the metal gasket got stuck on the 2 alignment sleeves. It was a royal PITA to dislodge it, but a big screwdriver got it free.
If the metal gasket is free and rotates around then this is not the problem. Maybe the pilot bearing died and debris damaged the input shaft's splines...could be getting hung up in the clutch disc. Fixing THAT will not be easy.
MAYBE it is getting stuck/cocked in the clutch disc. Try supporting the motor so that it cannot tip forward/backward when removing the tranny. Removing the tranny with everythign lined up might help free the input shaft. If it is all getting replaced (clutch parts), start shooting lots of Penetrating Oil up in there. The stuff is made of magic, I swear...saves my tail every time.
-
It just stopped. now it doesnt want to go on or off. I've been thinking it was the pilot bearing or the the input shaft just getting caught on the splines.
Its nice hearing someone else say it, now i dont feel so bad for thinking it.
-
Did the clutch make any odd sounds/grinding before, especially in neutral? Maybe the pilot bearing crapped out and fell out of the crankshaft, and is siezed onto the input shaft end. I will cross my fingers for you that it is not the case.
-
After you mentioned the pilot bearing possibly being the problem i figured 1 person ( besides myself) was enough. so i tried looking for the reciept from when i purchased the pilot bearing that is now in the car and couldnt find it. I opened the new pilot bearing that i ordered with my clutch kit and saw that the bearing was black and not peach (or whatever color you want to call it) like the one in the car now.
So as much as i didnt want to i decided to make a hole in the bellhousing and unbolt the pressure plate and hope i could see something. Then i put a screwdriver in the hole to get the pressure plate off the dowels. As im doing that the tranny starts coming off.
So heres what i see. the damn pilot bearing is stuck to the input shaft. I have not attempted to removed it but its really on there. Ill get it off tomorrow.

Now i have a damn hole in my bellhousing. I'm sure what i want to do with that. I dont know why i have to different pilot bearings when i ordered both from BMA, one was ordered over the phone and this second one i went to there Shop last Saturday and picked the kit up.
I'm sick so now that i finally have the bs done im going to bed. If i dont go to LBGP this weekend ill work on the trans some more. maybe just put a plate over the hole.
-
Well holy damn, I guessed right!
That is crazy man, putting such a hole in the bellhousing! I commend you on doing what needed to be done though. Drilling some holes and bolting in a small patch-plate should be sufficient here, or maybe mounting 2 steel patches and filling the gap between them with epoxy. Good luck!
-
Well im glad you did because you encouraged me enough to put me over the edge and say fuck it just do it. i was thinking of drilling 4 small holes, tapping them and bolting a plate over the hole.
-
Yeah that should be more than sufficient. I say go overboard and clean everything real well, and put some notecards over each side and fill it with epoxy. Or just screw some thin aluminum/steel sheet over it since nobody will ever see it and you can get back in should you ever need to. I demand pics either way :D !
-
Well im glad you did because you encouraged me enough to put me over the edge and say fuck it just do it.
I'm impressed too! The quick and dirty! If anyone asks you can say it's an inspection cover
-
well dang thats insane. I'm glad you got it off though!
-
Awesome!
A hole in the bell housing isn't a bad thing, just cover it up. After blowing several pressure plates on a previous car apart, my bell housing had some ventilation in it as well.
I'd use a puller to get the bearing off. Harbor freight, Sears, Autozone etc should have what you need.
-
I'm impressed as well that you did that. Don't forget to get a new dowel pin as yours seems a bit messed up. Congrats on getting it off.

For sure.

haha i like that idea.

How did you blow up your pressure plates? Yeah i'll get a puller from one of those places.

Yeah i maybe be ordering as much new stuff for the trans as possible since it is out and super easy to clean and get to the whole thing. I'm gonna replace
my fluid too.
I cant wait to get my Z4 3.0 shift kit too.
