Hello all,
I have an older e30 (Feb 1987) That has some sort of balancer/shield on the trans output to the driveshaft
I have removed the 3 bolts that I can get to on the flex disk, I have the drive shaft unbolted from the Diff and the center support is undone, but I can get the drive shaft out.
I have tried separating the two pieces but that doesn’t help there is not enough room to get them apart.
The flex disk/gubio seems to be stuck in the balancer/shield
see pics below.
What is the trick?
Not sure exactly what you are saying is the problem. Is the front end of the driveshaft/balancer seized to the output of the tranny, or is it that you can break it loose from the tranny but cannot find enough space to work it off the transmission?
Assuming the latter, if you haven’t, loosen the large collar nut on the center bearing. (It’s normal lefty-loosey). This should allow you to collapse the driveshaft and make it slightly shorter. A pry bar between the harmonic balancer and the back side of the transmission, after loosening the collar nut, should pull the front half of the driveshaft rearward, collapse it into the back half, and start to get the front end off of the tranny tailshaft.
After you unbolt the two 13mm bolts on the center bearing, let it drop, and after compressing the driveshaft, you should be able to work the harmonic piece off of the tailshaft of the transmission and get it free.
By the way, after you do get it apart, take that large balancer piece and throw it like a discus as far into the woods as you can. Source another set of three 17mm bolts/nuts to match the ones that remained and on reassembly, just put the driveshaft/guibo/tranny together without that damn balancer.
Edit: Upon closer inspection of your photos, that doesn’t look original. The factory setup has 3 studs mounted front-to-rear with nuts on the backside, and the other flanges have traditional bolts/nuts. Seems like the three you’ve removed so far should have been studs and remained poking through the driveshaft flange. Should be no matter, because with those three nuts/bolts/whatever removed, the process described above should still work.

here’s a procedure writeup that might give you some ideas

OK I got it out, The key was to hold the drive shaft and turn the balancer so the cut out aligns with the yoke on the transmission. Then put in the pry bar and give it just a little… POP the drive shaft is out. I will post some pics later with the cut out on the balancer.
Now to get the new drive shaft in.
Thanks for the help
