Am I missing something? Rocco 16v shafts = MK2 Golf

sure u can ust change the inner cv joint t fit the mk1 cant u ??

 

Hmmm, this deffo needs discussing.

As far as I know, the cabrio/Scirocco 100mm shafts are shorter than the Mk1 GTI shafts.

But I wasn't aware (and struggle to believe) that Mk2 shafts are the same length as the Cabrio/Scirrocco 100s.

People that put 16V boxes with 100mm flanges in GTIs on Mk1 shafts end up knocking CVs to bits, since those OEM Mk1 shafts are too long.

That's all I know for now....

 

so nwhat am i going t do ith my 16v mk1 conversion ??? ur saying dont use mk1 shafts with 9a/kr box ?? use kr shafts ??

 

do people just replace the flanges on the box with the 16v 90mm ones then?

Im just running an 8v box at the moment but been looking at 16v options

 

If you use 90mm output shafts, use Mk1 GTI shafts

If you use 100mm output shafts, use late Cabrio/Scirocco shafts.

The difference is caused (AFAIK) by the output shaft face sitting further out on the 100mm shafts.

 

I always thought only one of the two shafts on the Goof was longer...

 

The shafts are different lengths for mk1's, i've posted a pic before will see if i can find it, you can run into problems with the 100mm outers binding in the hubs too.There has been a few threads on it.

Rupe - great pic, just what was needed

By chance can you give the bare shafts a measure from tip to tip and help with the driveshaft FAQ here?

Cheers if you can.

It's either the driveflange face sitting further out on a 100mm 020 'box, or possibly also the actual length of the inner CV unit itself and the distance from the inner cv-bolt up flange to the circlip groove.

Thinking about it though, the circlip groove is dictated by the shaft, so that means it's the output flange.

 

Those shafts aren't bare anymore, but gillm measured some rocco shafts

from http://www.clubgti.co.uk/forum/showthread.php?t=148331

their is also mention of outer cv's being different lengths in that thread too.

 

Comparing a 100mm and a 90mm (new style 90mm for the springs and cones, like the 100mm), the 90mm is shorter

The 90mm flange is about 53mm from the face where the CV mounts to the end of the flange where the spring slides on.

The 100mm flange is about 61mm.

There is about an 8mm difference between the 90mm and 100mm flanges.

Lost me on an initial read there - but does it conflict or confirm what I wrote above?

 

you can mod the the mk1 shaft to take the 100mm cv,just needs a few mm turned of to allow you to fit the circlip.

 

Confirms

The 100mm flange on the 020 sticks out further than the 90mm flange.

About 8mm or so further on each side.

Ah I think it was me that fired us OT

But in a roundabout way, aren't we getting to an answer! We know the 020 'box width doesn't change when it has 100mm outputs on it - be it inside a Mk1 or Mk2.

So without changing anything else, this suggests that either a Mk1 has the same overall track width as a Mk2 < no!> or that the shafts are different, or that the outer CVs on a Mk2 are wider (which IIRC, they're not), or that the Mk2 hub design creates a wider track .

> forwards!
