Okay... big dissapointment here.
turns out that mk3 driveshafts flanges are not only larger, but the length of the driveshaft is longer too; approx 3/4 of an inch... uh oh...
and the actual flange sits out about half an inch as well...
has anyone ever changed the flanges to make this work??? i have another tranny sitting there with the 90mm flanges.
aside from that there is just the spedo cable issue, but i'm not concerned with that...
-
Are the u-joints the same size? If so, you could put a flange from the Mk3 shaft on the Mk 2 shaft, so it would match the tranny with the 3 end, and the diff with the 2 end.

oddly enough the shaft diameter on the driver's side is smaller :? :x
but i like your idea... maybe i'll just have the shaft cut & re-welded & balanced...
but if anyone has done it this way with success, please share!!
oh yea... don't forget that the flanges on the MK3 trans code CHE stick out about 1/2 an inch more too... so maybe just shortening the drive axles will do it.
-
There are also u-joints with one size one way, and another the other. I'd go to an auto parts store with someone who has been in the business a long time though, as they will know what you are asking about. If the slip joint has enough travel, I wouldn't worry about 1/2. Hey, arent you guys supposed to be metric up there? :wink:

:oops:
yea metric... so um... 1.5 cm? lol i didn't mic it or anything... i wish i could talk to someone else who has done the conversion, and find out what they did.
longer axles would be bad if i hit a huge pot hole or something right??? wouldn't it put a lot of stress on the shaft & tranny ???
-
i have a mkII transmission in my mkIII car. it has the 100mm (mkIII) output flanges in the mkII transmission (which originally had 90mm's)which then allow the mkIII axles to be used.
similarily, in your case, (i think) 90mm (mkII) output flanges could be put into your mkIII transmission. and it should all bolt up. i think :lol:
alternately, you hybrid the 100mm inner CVs and the mkII axles...

yep

:lol: we have to straddle both systems so we can still do business with you archaic americans!!

cool! so did you do the flange swap or someone else?
-
i believe dr. diesel did on that car. its not a difficult job though. you have a bentley right?? :lol:

sure do!!! funny people on here say i just need the 100mm drive axles :roll: lol... but i like a good challenge!
anyone in need of 100mm mk3 axles??? :lol: i was hoping to use them, as i just found out that my driver's side axle has a tear in the boot coming from the tranny side... :evil:
ill probably stop over at the stealership sometime and grab those caps... i've talked to a transmission guy and he said that it's real easy to take the flange off, but doing so while saving the cap is a bit tough... and in a pinch would put silicone to seal it up.
also, the tranny i'm stealing the flanges from is an N/A (yet to get the code) but if anyone wants to buy it real cheap, it works, but i don't know about grinds etc...
i've been itching to get this transmission in my car for a while now... the ratio's i have now are pretty disgusting
-
hrm.. i think that there are 100mm mkII axles out there. maybe for GTI or scirocco. they might fit without changing anything else...
-
Hi there,
Are you using the Mk3 02A cable trans? If so then the axles / driveshafts from a Corrado G60 should bolt right up.
Don't your 100mm inner CVs fit on your old driveshafts?

Yes there are 100mm mk2 axles
9A
2Y
ACD
AGB
ACL
AON
AUG
as stolen from www.scirocco.org/gears
I might have a set of 100mm ones in my garage come to think of it...
-
hmmmm... should i really go with 100mm though??? i'm only looking to get around 100 hp and 160 ft/lbs torque... 90mm's can handle that right???
-
I'm pretty sure they can handle it, but what's easier, swapping complete axles or flanges?
-
for ease finding direct swap axles would be best. alternately you could fit 100mm CVs to the old axles, i think they will fit as Mikki suggested. you might as well keep the 100s, no harm in it. if you have the 90mm flanges and no other parts, you could put them in that gearbox for time/money savings.
-
well i have a 1.6N/A tranny just lying around... with the lower gearing i would probably never use it unless all my tranny's blew... so why not just use the flange's from that?? :) i mean.. it's bad enough that i bought mk3 100mm driveshafts... now if someone wants to trade me good used MK3 driveshafts for the MK2 100mm driveshafts, i'll do that.
I also bought a reman driveshaft ... the boot was torn all the way around and was getting no lube :( finally found out what that clicking noise was :roll: and was looking to keep that one good driveshaft.
i can't wait to try this tranny out on a dirt road though (not that my car makes that much power, but the tranny does have a peloquin 80% diff :twisted: )
-
Please let me know how that diff is, I was thinking of getting one for my next car.
I'll check my garage and see if I have any 100s, you can have them for cheap. They will need to be repacked though

if they are exactly the same length as mk2 90mm's then i'm all for it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! shipping might hurt though, but it will be a lot easier.
personally i think that $800 for a peloquin kit is wayyyy too much... do you have access to a relatively cheap kit somewhere???

There is one for sale on vortex installed in a short ratio tranny for $750 OBO
They are mk2 axles. My friend and I parted out a car about 2 years ago and it had 100mm axles. I'm just not sure if we scrapped them or not

$750 OBO... hmmmm I guess that wouldn't be too bad!
-
ok well MK2 flanges on MK3 CHE tranny. DONE
for my first time doing this, i think i did quite well!
funny how one side of the mk3 tranny had an allen screw holding it in, and the other side had the rubber sealing cap. (so i have an extra rubber sealing cap...)
forgot my camera :( i would have taken pics! honestly!! :lol:
i find that turning this tranny by hand via the flanges is much harder than on my mk2 n/a diesel tranny. wonder if that is because of the limited slip?
-
I've seen this happen many times on other forums I'm on. Take and knock the 100MM CV's off of your new axles and put them on your old ones. From there should bolt right up.

yea but the 100mm flange on the tranny sticks out another little bit... this way swapping the flange's i won't need to worry about clearances etc.
