Title: can i change my original gearbox flanges
Post by: matping on 07 April 2011, 21:20
i cant get my head around all this gear box stuff   . to put my 1.8 20v turbo in my mk1 ive been told loads of things  ive been told i need 100mm short  drive shafts  ok no problem
then i get told i need  100mm flanges on the box!  which my box doesent have  so i get told i  need to change my box to a box with the 100mm flanges

got told tonight i can just change my original flanges on my original box to 100mm ones to fit the 100mm short d/shafts  ????
this would be the best option for me so i dont have to buy anouther box ! can anyone confirm this for me that i can just change the flanges lol ?   

                          cheers guys  :wink:

Yes you should be able to change just the flanges.

right after a  day of ringing around this is what you need if you want the 100mm gearbox flanges to fit the 100mm short driveshafts
this is for the standerd box from a AGU 1.8 20v T  02J . so its just a matter of changing the flanges
             part number      02A409355D
             from  TPS
             59.58 each

             SORTED !!      :wink:

i havent got around to doing them yet  ive taken the drive shafts off  to reveal the flange  my flange is on with a allen key stud so im guessing when ive unscrewed that  ill have the clip to get out

my 020 box was exactly as shown on broke vw. dont know about your allen bolt mate. is there a cap in the centre?

i think you will need a puller to get the flange off as they should be tight on the shaft. i used this

with some long m8 bolts n washers and got a bit of m10 threaded rod n nuts and large washers when pushing it back on.
did you get new seals? they are 65x50i.dx10

what i remember buddy from the outherday was  i took the passenger d/shaft off with the 8 bolts or so  from the flange . then there was a cap that had 3 metal clips on it that was attached to the shaft  in a star shape as the flanges are star shaped the cap came off attached to the shaft . . ! anyways all this off revealed a allen key stud in the centre of the gearbox flange and thats where im at at the mo  lol any ideas?? think its a 02j aswell !

undone the allen bolt  :smiley:  the flange just pop'd straight out . i havent taken it completely off yet tho as diddent want oil everwhere so im guessing  it should just slide off  and must have a spring behind it .
looks like a tool to be made to compress it back on bud
