Gearbox question
« on: 12 October 2016, 19:34 »
I think my gearbox is on its way out. Mr Brokevw reckons its something requiring a rebuild but there is only one gearbox specialist on the Isle of Man and he is expensive. This leaves me looking for a new box, im currently running a 2.0 8v block with an AUG. Ive had a look in my local breakers and he has a mk3 8v gti with a DFQ. So what do i need to make it work? Is it just a 16v clutch kit? Im aware that 3rd to 5th is a tad longer. Cheers

James

I take you have the 8v box. From a mk2.
What is the actual issue with it?
If going mk3, as already said you need the centre plate so that the input shaft will match up with the splines and go on. Although the 1.8 8v has 3 different clutches so yours could be the right centre already

Im lead to belive something in the range of 1500 as the repair man has to take the box out the car.

Cost of getting a box over here is a minimum 50 quid plus shipping to lancaster. Or if i go away to pick it up, 250 quid plus time/fuel

Couple of videos of the noise, happens in a straight line. Gets worse going round one direction of corner, better the other way (cant remeber which). Ive changed the front wheel bearing on the loaded up side when noisy. In these vids the only thing i did to make the noise more noticable is dip the clutch to reduce exhaust noise. Also The speed/pitch of the noise changes with the wheel speed which made me think, wheel bearing/driveshaft/worse.

about £500 is the going rate for a rebuild. and the boxes take about an hour to remove. so that would make it £500 an hour labour :shocked:. have you checked the gear oil level? also the driveshaft cv joints?

Are you not very good with the spanners? Could you not take the box out and attempt to fix it yourself? When I took the box out of mine yes I was slightly nervous I'd f**k it up, but with the help of Mr BrokeVW (the guy is a legend!..) and the guide on his site, I did a fifth gear conversion, slapped it all back together, and it is still running as sweet as.

you don't have to remove the box for the 5th gear conversion. if you take off the front engine mount, you can lower the whole lot down enough to get the 5th gear housing off.
