Driveshaft Guibo size

FrankM E30 · 03-23-2006, 10:26 AM

#1, how do you measure the Guibo size... 110mm opposed to 135mm.. Is it the outside diameter? or the center hole to opposite center hole?

#2, What E30 driveshafts were offered with the bigger (135mm) guibo? I have a 325 super eta and just took it off yesterday and it looks like the bigger one...

Considering that i'm doing an M30 conversion, it's a good thing.... but overall.. I know RS4Pro had a bigger flange on his driveshaft.. just curious if I have the same thing...

IIRC it was just the very early cars that had the larger one. You can tell by the size of the bolts. The larger ones use 12mm the smaller ones use 10mm.

nope, only the 87 325e's got the larger guibo. I specificaly purchased a driveshaft from one for that reason. I think it was pre 1/87->9/87 that got them.
and the measurment is the outside diameter.

FrankM E30 · 03-23-2006, 05:20 PM

That's really odd ely... bc when i took the tranny off yesterday from my 88 325 (super eta), it was the larger size.. appx 5.3" outside to outside.. which is classified as the larger flex disc.. interesting huh?

makes it much easier...driveshaft portion will be a cinch

Oh yeah ely, what position did you use? ... to make sure u have no driveshaft modifications??

rs4pro3 · 03-23-2006, 05:32 PM

position 3, maybe the super eta's got the larger guibo's also

SpecM · 03-24-2006, 08:33 AM

-^Mine has the larger one.

Joey Link · 03-02-2007, 02:59 AM

Is there any way to figure out which you have without looking and measuring it? Mine looks like a clump of broom bristles, and I need to know which I need for my '89 325iC.

FrankM E30 · 03-02-2007, 05:11 AM

That means your guibo is baaaaaaaaaaad. I guarantee you have the smaller guibo. Check out this site http://www.wholesaleimportparts.com/...7;20Driveshaft

Either front tri-prong holes are 2.6" or 3.12" apart. I'm willing to bet you've got yours at 2.6".

Enjoy!

so which car has the 135mm flex disk???

JoeMadoo · 08-15-2007, 03:37 PM

Every 325e car including super eta after 5/86 has a large guibo. A 325i regardless of the year always has a small guibo.

Funkmasta · 08-17-2007, 01:06 PM

89 325ic is going to have the smaller guibo.

late 86?-88 "e" manual trans cars have the larger guibo, as do M3's

Yep, I've seen the same too.

I have a large guibo in my 88 seta, and I'm having a terrible time finding a replacement DS. SUCKS.

wildstoats · 09-16-2009, 07:04 AM

I have a brand new one that I might not be using now. Damn Getrag 265's messing with my plans, haha
