Strongest gearbox for 3B

[Beetie]

Excellent idea Beetie

[1975DCS]

So how did this all ended up?

[4WheelDrifter]

You could ask Audiman. But I think he's gone deaf from all that gearbox noise.

Actually I'm interested in whether it's possible to get stronger bearings for the ARV.
I heard that MTM did a kit to strengthen the 5 speeder, but not from a reliable source.

I'm interested in this too, as I also have a 3B 5 speed. The synchro on second gear ocassionally plays up, so I doubt I have too long before I'm looking at a recon or replacement.

urQ tranny

The strongest box (by far?) is the urq box but the ratios are not ideal and you'd have to change the diff, topspeed would be reduced. Next in line would be the RS2 box with the strengthened first gear.

the urQ does have 3,889,and will raise the topspeed ,thats for shure have 2 trannys at home,for my projectcars

This has been talked about before....... the 016 not as strong as some say (read)

But I have heard that Jonus for example

was running 850bhp using the original 90 quattro N/A 016 gearbox!

jonus did use the old 016,in the old engine setup, but in the new setup he using the 01e with the thorsen unit(the thorsen are only one peace of steel,so the thorsen not workin,spool unit)

I've done a few 01e rebuilds now and as far as I know there are no substitutes
for the main beraings .
It's a custom made bearing with collars and flanges etc .
Available at the audi dealer or at an SKF shop .
Abt 150 euro a piece .

I've also searched various bearing catalogues for a matching part .
Maybe with a little machining , or an intermediate part or so .
No go . There's not enough room .

But taking them apart and back together again was fun you know .
The first one took a week . Machining the special tools not included .
The last one only took two days .

Pat, what do you estimate the cost of a tranny overhaul is, that is mainly syncro mesh upgrade and what ever other neseccary parts that has to be changed?

What special tools would be needed for such an overhaul?

Regards, Johan

[stragenmitsuko]

New main bearings ( price of gold ) , diff bearings ( std skf , pretty cheap ) new synchromesh rings and you'll be close to 700 euro .
And then it depends if other parts need to be changed or not .

As for special tools . I've machined them all from scratch .
Mostly pullers and pushers .
And there's the pignion position measuring tool That was a tough one .

Look at the pictures here . The text 's in dutch .
Halfway the tread .

Very impressive, not a very easy tast to do even if you have all the needed parts and tools!

Thanks for the link.

If I have understood correctly there is no 5-speed 01E box that has both, the wide 1st gear and the flexible mainshafts ? so if I want a 5 speed box, , i have to accept the fact that i can't get both ?

[AndyP]

AFAIK the 5 speed O1E box does not have the wide 1st gear OR the flexible main shaft. These were upgrades only fitted to late 6 speed S2 and RS2 gearboxes.

[Tuna]

when I go through the material at this link:

http://elektro.cmhnet.org/~charlie/photos/cars/01E/

it looks like that CBD boxes with a number over 80045 has the wide gear and the all DPM and finally the 2 pieces of CET

CET 01E 300 043 E/EX/EV has wide gear on numbers under 79843
CET 01E 300 044 J/JX/JV has wide gear on numbers above 79844

as I understand it the flexible main shaft was introduced only to the 6 speed.

I may have interpreted the homepage wrong, if so please correct me, my English is not the best.

AndyP , which of CET boxes do you have ?

Johan

I'll get it out at the weekend and have a good look and take some pics.
